| | (n)vi - Erase in ex mode Posted: 15 Jul 2022 03:22 PM PDT How does one erase characters in ex mode (':' command line) of (n)vi 1.79 or make 'Backspace' behave as in Vim? 'Backspace' and 'Delete' only move the cursor left, from where new keystrokes overwrite instead of preferably inserting. This is the same for insert mode, but I can use 'Esc' to clear everything after the cursor; 'Backspace' does erase at the shell command line. I am using (n)vi in xterm in fvwm, each of which are included in a new OpenBSD 7.1 installation. Note that Vim and its vi command, i.e. :set compatible, are not the same implementation as (n)vi.

Posted: 15 Jul 2022 12:53 PM PDT I have run in to the Nagle / Delayed ACK problem that causes 40ms overhead on small TCP packets. According to Redhat documentation I can add the quickack 1 option to the route and it will disable the Delayed ACK feature. So, this is what I did: [root@x]# ip route show default via 10.100.11.1 dev ens192 proto static metric 100 10.100.11.0/24 dev ens192 proto kernel scope link src 10.100.11.13 metric 100
And then I added the quickack option to my interface: [root@x]# ip route change 10.100.11.0/24 dev ens192 proto kernel scope link src 10.100.11.13 metric 100 quickack 1
This solved the problem. However, how do I make this change permanent? Or is this even the best method for disabling this feature? I tried to add 10.100.11.0/24 dev ens192 proto kernel scope link src 10.100.11.13 metric 100 quickack 1 to /etc/sysconfig/network-scripts/route-ens192 but it did not persist.

For reference, this is a script that DOES work. It converts selected .MP4 files to .mkv, copies the time stamp and prints some feedback to the user. #!/bin/bash for i in $NAUTILUS_SCRIPT_SELECTED_FILE_PATHS do ffmpeg -i "$i" -movflags use_metadata_tags -c:v libx265 -crf 26 -preset slow -c:a aac -b:a 160k "${i%.*}.mkv" && touch -r "$i" "${i%.*}.mkv" && notify-send "Converted '$(basename "$i")'" || notify-send "Failed converting '$(basename "$i")'" done notify-send "Conversion finished"
Now, this is a script that DOESN'T work. It should convert selected .m4a files to .mp3, add a cover image and some tags, copy the time stamp and give some feedback to the user. #!/bin/bash for i in $NAUTILUS_SCRIPT_SELECTED_FILE_PATHS do ffmpeg -i "$i" "${i%.*}.mp3" && eyeD3 -a "Author" -A "Album" --add-image="cover.jpg":FRONT_COVER "${i%.*}.mp3" && touch -r "$i" "${i%.*}.mp3" && notify-send "Converted '$(basename "$i")'" || notify-send "Failed converting '$(basename "$i")'" done notify-send "Conversion finished"
When I run this one, I get multiple errors that say "Failed converting (a part of the path to the file)"... for some parts of the path to the file, like parts of folder and file names. I'm not sure what I'm doing differently here. I'm using the same $NAUTILUS_SCRIPT_SELECTED_FILE_PATHS parameter, but it doesn't work the same in the second script. As a reference, this other script, which is the same as the second one but applies to all the files in the folder, does work perfectly, so I'm sure the commands inside do do work. #!/bin/bash for i in *.m4a do ffmpeg -i "$i" "${i%.*}.mp3" && eyeD3 -a "Author" -A "Album" --add-image="cover.jpg":FRONT_COVER "${i%.*}.mp3" && touch -r "$i" "${i%.*}.mp3" && notify-send "Converted '$(basename "$i")'" || notify-send "Failed converting '$(basename "$i")'" done notify-send "Conversion finished"
What am I missing? Can the $NAUTILUS_SCRIPT_SELECTED_FILE_PATHS only work with certain file types? Is the issue somewhere else? | | Why does /etc/resolv.conf keep changing? Posted: 15 Jul 2022 02:29 PM PDT I am running a debian based linux vm using virt-manager with two ethernet interfacs one connected with NAT and the other is bridged to br0, in /etc/network/interfaces I have the following configuration auto lo iface lo inet loopback auto eth0 iface eth0 inet dhcp

The build itself is quite simple, as there are no binaries to build – every file that will be installed on the target system is already present in the source tree. Now the build process fails with an error message I cannot make sense of: dpkg-genbuildinfo: error: badly formed line in files list file, line 1 dpkg-buildpackage: error: dpkg-genbuildinfo subprocess returned exit status 25 debuild: fatal error at line 1182: dpkg-buildpackage -us -uc -ui failed
What is the files list file mentioned in the error message – does that refer to the .install file?

The debian dir is copied and stripped down from another (more complex) package I built earlier, which completed without such errors iirc. Nonetheless, I do end up with a deb package which seems to have everything in place – scripts as well as files to install. (Which indicates that the .install file cannot have been all that wrong, at least the files are getting collected.) What is wrong here?

Posted: 15 Jul 2022 04:01 PM PDT I'd like to disable my CD/DVD drive so that it doesn't spin up every time I select Save in my Kate editor, or select a file-accessing action in other applications. The spinning up just delays what I'm doing, and I'm not even using the DVD drive. I want to leave the CD in the drive, and not have it spin up. I found a website that said a udev rule will definitely disable the drive. So far, I've tried the following 2 rules (separately), but neither of them disable the DVD drive (it still spins up - even when not mounted): ENV{ID_SERIAL}=="PIONEER_DVD-RW_DVRTD11RS_SAC1009942", ENV{UDISKS_IGNORE}="1"
KERNEL=="sr0",ENV{UDISKS_IGNORE}="1", RUN+="/bin/touch /home/peter/udev-rule-ran"
The RUN+ in the second instance, creates my test file "udev-rule-ran", so this tells me that my rule file is being executed, and that the rule line is being run. My Question: Could you tell me what I should be doing to definitely disable the darned DVD drive? I also want to be able to enable the drive again on the occasions that I need it. Supplementary Details: I'm trying very hard to write a udev rule to disable my CD/DVD drive. I've tried various non-udev methods to disable it but none of them work. There is no loaded module¹⁾ for the drive that I can unload, so I can't use that method to disable the drive. ¹⁾ So I think the driver must be compiled into the kernel. | | Understanding network problem (syslog) Posted: 15 Jul 2022 01:01 PM PDT I am running a lubuntu 14.04 server and its always worked well, except for the last couple of days it keeps dropping off the LAN.

I like my workstation to be close to silent and I just build a new system (P8B75-M + Core i5 3450s -- the 's' because it has a lower max TDP) with quiet fans etc. and installed Debian Wheezy 64-bit on it. And something is getting on my nerve: I can hear some kind of pattern like if the hard disk was writing or seeking someting (tick...tick...tick...trrrrrr rinse and repeat every second or so). In the past I had a similar issue in the past (many, many years ago) and it turned out it was some CUPS log or something and I simply redirected that one (not important) logging to a (real) RAM disk. But here I'm not sure. I tried the following: ls -lR /var/log > /tmp/a.tmp && sleep 5 && ls -lR /var/log > /tmp/b.tmp && diff /tmp/?.tmp
but nothing is changing there. Now the strange thing is that I also hear the pattern when the prompt asking me to enter my LVM decryption passphrase is showing. Could it be something in the kernel/system I just installed or do I have a faulty harddisk? hdparm -tT /dev/sda report a correct HD speed (130 GB/s non-cached, sata 6GB) and I've already installed and compiled from big sources (Emacs) without issue so I don't think the system is bad.

| English equivalent of German da- constructions Posted: 15 Jul 2022 02:53 PM PDT In German, the prefix da- can precede a number of prepositions, and in each case the compound da preposition is an anaphor, with the meaning of the preposition itself + it. For instance, the preposition mit means 'with' in a variety of senses (accompaniment, instrument, amongst several others); the compound version of this preposition, damit, means 'with it/that'. So Wenn ich endlich damit fertig bin, kann ich draußen gehen means When I am finally done with it, I can go outside. Naturally, the interpretation of 'it' - i.e. what it refers to, its antecedent - should be available from the context. Now, you may well be familiar with the anticipatory 'it' in English. The anticipatory 'it' functions as a substitute for an extraposed subject. For instance, It is rude to speak like that. [To speak like that is rude.] It is such a pity that he is so clueless. [That he is so clueless is such a pity.] I fin etc. In these constructions, 'it' is said to anticipate the subject. I probably ought to note that 'it' can sometimes be used to anticipate an object, as in I find it amazing that no one has yet questioned the politician on this matter. In these cases, the extraposition is obligatory. In German, the compound da prepositions can likewise anticipate clauses. For instance, Ich freue mich darauf, dass wir nächstes Jahr nach Deutschland fahren werden means I am looking forward to going to Germany next year, but translates literally to I am looking forward to it, that we are going to Germany next year. Similarly, Es hängt davon ab, wie viel Geld wir verdienen können. means It depends on how much money we can earn (where 'it' here refers to whether or not they can go to Germany next year). Literally, however, it translates to It depends on it, how much money we can earn. In German, the need for anticipatory da constructions arises from the fact that a preposition cannot directly take a clausal complement. In English, this is not so: English prepositions can take as complement all types of clause but one, namely the content clause. In the case of the content clause, an alternative construction may be used: preposition + the fact + content clause. Here are some examples of this construction, as well as of clausal prepositional complements: I am looking forward to going to Germany next year. I agree with what she says. She is familiar with how the education system works. We need to get used to the fact that the entire world has changed etc. Although this overview of German da prepositions is by no means comprehensive, it is sufficient for the purpose of this question. For more information, I refer you to the following: Libre Texts - Da- Compounds University of Michigan - Germanic Languages and Literatures Learn German with Herr Antrim
Now, without further ado, on to my question. In English, there exists a similar class of words to the German da prepositions: namely, the there compound prepositions. Amongst these are the following: thereby, therewith, thereto, therefor, thereupon, therein, thereafter, therein, thereat, thereto, therefrom Many of these compound prepositions are now archaic, or used exclusively in legal writing (or by quaint linguistic antiquarians). However, I am curious to know whether or not there were constructions in archaic English that employed the there compound prepositions in a similar way to the German da anticipatory constructions. In other words, did archaic English have anticipatory there constructions? Would sentences such as His argument relies thereon(,) that all the accused are guilty. and I am looking forward thereto(,) that we are going to Germany next year. have been grammatical, or indeed commonly uttered? (Naturally, the wording of the above sentences would have been different in archaic English, but I hope I have conveyed the thrust of my question.) | | What does this sentence imply?

Posted: 15 Jul 2022 09:37 AM PDT I'm a Polish-English translator and I work mainly with legal documents. There's a phrase in Polish: "między innymi" (abbreviated as m.in) that means quite literally "among others". It's used everywhere in legalese; mostly in numbered lists: The program dedicated to the employees, pursuant to which, i.a.: (i) an Employee, at his/her request, may be assigned to work for another company in the Group for a period of 3 to 6 months; (ii) the Employee performs work during the assignment period under the supervision of the host company, but still under the Employment Contract. "Między innymi" can be used in both formal and informal texts. Now, here's what I think (correct me if I'm wrong): "among other things" sounds informal to me (because of the "things"). "Among others" usually refers to people. Neither of them can be abbreviated (?). Inter alia, or i.a. (is the punctuation/space correct? Also, is this abbreviation common and understandable to non-lawyers?) are both great, sure. However, I'd like to have more than this one option, especially when the document is intended for clients who don't always understand legalese. I've thought about "including" and its variations ("including without limitation"/ "including but not limited to") don't work with all sentence structures.

Now I understand that 'Most Hungarians' is a plural subject, so should the 'good English accent' agree with the plural subject? However, I'm not trying to say that each of them has their own distinct 'good English accents', I'm trying to say that they have a single English accent that is perceived as good by the general public. That is why I'm inclined to say 'a good English accent'. Which one is grammatically correct?

Posted: 15 Jul 2022 03:13 AM PDT I always learnt that "more than one" takes a singular verb because it is followed by a singular noun as in: more than one child has bad grades. But what happens when it is followed by a plural noun? For example: more than one of the children [has/have] bad grades? Grammarphobia says when "more than one" modifies a singular noun, it goes with a singular verb: "More than one person is going." But when it's followed by "of" and a plural noun, it takes a plural verb: "More than one of the people are going". -->https://www.grammarphobia.com/blog/2007/12/can-more-than-one-be-singular.html on the other hand, this site suggests a different answer: more than one of the authors has received the Nobel Prize. "More than one," although plural in meaning, always takes a singular verb. Another such idiom occurs when "one or two" acts as the subject: One or two was found in the kitchen. (However, "one or two were found in the kitchen" is also acceptable). -->https://crosstalk.cell.com/blog/10-tricky-cases-of-subject-verb-agreement And what happens when the sentence is preceeded by "there is/are" or "here is/are? So in the end what verb should I use? How can I correctly write these sentences: More than one of the dolphins contracts/contract dangerous diseases. More than one of them contracts/contract dangerous diseases. There is/are more than one sick dolphin. There is/are more than one of the sick dolphins. There is/are more than one of them. Normally I'd use the singular for all of the sentences above, but grammar sites made me lose my sense of grammar, of which I had little to no knowledge!

Posted: 15 Jul 2022 09:02 AM PDT Let consider context (e.g. historical recent past) where modern meaning of missile as a self-propelled ordinance with reactive or jet engine doesn't exist. Then its original meaning is "an object which is forcibly propelled at a target, either by hand or from a mechanical weapon" (Oxford). How it is different historically it was from projectile (if it was), which same source defines as "a missile designed to be fired from a gun" or "an object propelled through the air, especially one thrown as a weapon". Were they full synonyms, were they used interchangeably or projectile had appeared later? | | What is the origin of the joke 'a freckle past a hair' when one is asked the time of day?

Posted: 15 Jul 2022 04:11 AM PDT I am looking for an idiom or expression which can be used to describe the action of someone deliberately playing below their skill level. For example, a pool or billiards expert missing a few shots on purpose. There are 2 situations where I am looking to use this expression, so, for any potential answer, I would like to know if it fits one or both of those meanings: 1. Negative Connotation The player is playing below his/her skill level because they are trying to deceive (for example, getting their opponent to feel overconfident and bet money on the next game). Example usage: He's ______-ing! He wants you to believe that he's less skilled than he actually is. 2. Positive Connotation The player is playing below his/her skill level because they want their opponent to have fun and not feel bad about losing by a heavy margin. Example usage: My father-in-law wanted to play chess so I had to __________ because winning in a few moves might have been a bit humiliating.
What I considered The expression "to dumb down" came to mind initially but it means something different. The verb "to hustle". Dictionary definitions seem to imply that it would work only for the case with the negative connotation, but I am not entirely sure. Cambridge Dictionary suggests several meanings of the word, but the most relevant one is: a dishonest way of making money However, I believe that in colloquial usage the word tends to have a neutral or even positive meaning: hustlin' The problem I have with this word is that it seems to be connected to money, but I would like something more general and not specific to making money. To go easy: This seems to fit the case with the positive connotation, for example, "I decided to go easy." So this is one I'm heavily considering. To smurf: This slang word fits well but it's only used in online gaming as far as I know. | | Synonym for to-be-discovered?

通过微信读书 API 抓取读书笔记到本地数据库。 -
通过判断笔记 /高亮划线生成的时间戳，过滤出自『上次导入时间』-『当前时间』这一时间段的所有笔记 /高亮划线内容。 -
将过滤出的所有笔记逐条打上『#YYYY-MM-DD 』格式的日期 tag 和『#书名』 tag ，外加 1-2 个自定义 tag ，例如『#inbox 』。 -
将输出的笔记写入到一个名为 WR_YYYYMMDDmmss(本次导入时间).md 的文件中，并自动将这个文件存入 Logseq 的 pages 文件夹下面。 它的目标用户群应该主要是，以微信读书为主要阅读器，喜欢同时阅读多本书，有回顾 /深度处理读书笔记的刚需，并且主力使用 Logseq/Roam/Obsidian 等双链笔记工具进行个人知识管理的人群。 名字我也起好了，就叫『微信读书时间胶囊』。 | |

| | Does SignInAsync have the ability to create jwt like how it does for cookies? And whether to avoid using SignInAsycn when using JWT auth? Posted: 14 Jul 2022 02:50 AM PDT I have a project with .NET Identity tables and SignIn and User manager. The SignInManager.PasswordSignInAsync checks whether the username and password is correct and if so then it will create the cookie as part of the response. Currently the authentication configured is the default cookie based. Following is the existing example of login action: [HttpPost] [AllowAnonymous] [ValidateAntiForgeryToken] public async Task<ActionResult> Login(LoginViewModel model, string returnUrl) { if (!ModelState.IsValid) { return View(model); } // Require the user to have a confirmed email before they can log on. var user = await UserManager.FindByNameAsync(model.Email); // This doesn't count login failures towards account lockout // To enable password failures to trigger account lockout, change to shouldLockout: true var result = await SignInManager.PasswordSignInAsync(model.Email, model.Password, model.RememberMe, shouldLockout: false); switch (result) { case SignInStatus.Success: return RedirectToLocal(returnUrl); case SignInStatus.Failure: default: ModelState.AddModelError("", "Invalid login attempt."); return View(model); } }
I want to change this to JWT based and for this I plan to create the following: - GetUserFromDb(username, password) - this will be called instead of
SignInManager.PasswordSignInAsync and it will check in the db if the user exists and return the user details - CreateJWT(userdetails) - the output of point 1 will be passed into this method as an argument and this method will build the JWT token with user name, and all the claims.
- Change the authentication scheme in startup to JWT bearer based
Instead of doing any of the above manual work, I want to ask- - Suppose I change the authentication scheme to JWT bearer based, then does
SignInManager.PasswordSignInAsync have the ability to return a JWT rather than the cookie? - During User registration, I can continue using
var result = await UserManager.CreateAsync(user, model.Password);. But during login does it make sense to use SignInManager.PasswordSignInAsync (to check user/password) and then call the GetUserFromDb (to return user info) followed by CreateJWT (to set JWT)? Or should I prefer to not use the SignInManager.PasswordSignInAsync? - Does
SignInManager.PasswordSignInAsync create cookie in the response only if the authentication scheme is default (cookie based) or does it do so even if the Authentication scheme is changed to JWT bearer based? In this case it doesn't make sense to use SignInManager.PasswordSignInAsync when doing a JWT based authentication? | | Query the Euclidean Distance between points and and format your answer to display decimal digits Posted: 14 Jul 2022 02:51 AM PDT select round((sqrt((pow((max(lat_n)-min(lat_n)),2))+(pow((max(long_w)-min(long_w)),2)))),4) from station;

I've tried with this method: public static bool RunCommand (string command) { try { ProcessStartInfo startInfo = new ProcessStartInfo { FileName = "cmd.exe", Verb = "runas", Arguments = "/C " + command, UseShellExecute = false }; Process process = new(); process.StartInfo = startInfo; process.Start(); process.WaitForExit(); return true; } catch (Exception) { return false; throw; } }
I've tried passing the following commands as the argument "command" in order to show up the Task Scheduler: - "taskschd.msc"
- "start /wait taskschd.msc /s"
- "C:\windows\system32\taskschd.msc /s"
- "control schedtasks"
The idea is to continue the execution of the main program when the Task Scheduler is closed (its process is killed), but the "process.WaitForExit();" instruction is linked to the cmd command, so the main program continues after cmd process is closed, even when the Task Scheduler window is still being displayed. The problem is that the "taskschd.msc" process, when launched, is wrapped into an "svchost.exe" process. I can't determine its PID because of the many different svchosts running at the same time, so I can't kill it manually either. I've tried the solutions proposed here, but to no avail. I've also been looking for a way to give an alias to the the "scvhost.exe" process launched with this cmd, but it seems that's not possible. I've been thinking of compiling a new exe just to launch the Task Scheduler under a process name that I could control, but I don't think it is a good solution. Any ideas, please?

I already tried to restart my adb server and remove and create a new emulator, wipe the data and try to cold boot it, but the issue persists.

Emulator: Google Pixel 3 API 30 | | PowerBi Service principals and Row level Security Posted: 14 Jul 2022 02:51 AM PDT We are using PowerBi and would like to embed a report in another system. We have set up everything so far and can display the reports with a service principal for several users. However, we only want the users to see their own records, so we have created roles that only display a few records based on the username. This works well in the PowerBi Desktop 'view as'. But when we request the embed token from the other system, we get a 400 response code back. I have read the following(https://docs.microsoft.com/en-us/power-bi/enterprise/service-admin-rls): Service principals cannot be added to an RLS role. Accordingly, RLS won't be applied for apps using a service principal as the final effective identity. Can I then achieve my goal at all, that a large group of users can view a report and only see their own data? Or is that only possible if I create a separate account for each user? My report without roles can be embedded. That works. Then I added a role to my report. Role is Owner and DAX is [Owner__c] = USERNAME()  And adjusted the body of the API from: { "accessLevel": "View", "datasetId": "8d72284e-f104-4213-9376-606397b2f838" }
to { "accessLevel": "View", "allowSaveAs": "false", "identities": [{ "username": "0015p00005ZSE7wAAH", "reports": ["7fa1badb-ccb3-45b8-84cb-15e5b2018efa"], "roles": ["Owner"], "datasets": ["8d72284e-f104-4213-9376-606397b2f838"] }]
} This is a my datatable  Did I miss a point? Do I need to add someone(who?) to this the role under dataset security? Why is USERPRINCIPALNAME() or USERNAME() not the id, which I defined in the request body? As soon as I add a role to my report(Dax:[Owner__c] = TRUE) or ([Owner__c] = USERNAME() or even hardcoded [Owner__c]='0015p00005ZSE7wAAH') I get a status code 400 | | How to modify request headers in Next.js Posted: 14 Jul 2022 02:51 AM PDT I have a need to add a header to each request to the server.

In official docs, it is mentioned that $listeners object has been removed in Vue 3. Event listeners are now part of $attrs. It is taking non-prop attributes (class, style) as well.

Icon-component: <template> <vu-button v-bind="buttonProps" :class="buttonClass" v-on="$listeners" @click="buttonToggle"> <vu-icon v-bind="iconProps"><slot/></vu-icon> </vu-button> </template>

My program parses this data into a vector map, then uses this data to construct an xml file using boost::property_tree. The text file is about 3500 lines, and the program consistently crashes at line 1773 with: terminate called after throwing an instance of 'std::bad_alloc' what(): std::bad_alloc Aborted (core dumped)
At first I thought maybe the size limit was being reached, but reading up on std::string shows that the target computer should be able to allocate the size required.

I am reorganizing our Azure environment and part of that is converting mail enabled security groups to dynamic M365 groups. There is about 1600 groups. My PowerShell script to do this has been created and is working as expected. I have not made these changes to all 1600 groups my D-DAY is the 22nd. This brings me to my issue. When I created my test groups, I noticed that when I pull up the new group in the "To" field in outlook (pulled from the GAL, not using the autocomplete) I noticed that when I hover over the new group email in the "To" field I get a pop up saying there are no members in that group. I checked in Azure and o365 and I have all my 10 users in there, pulled in using my dynamic rule syntax. I do not know why it is showing no members. Being able to see who is in those groups will be well used by our users and something like this will generate a whole bunch of support calls\tickets.

Using Apache virtual blocks, .htaccess or other solutions? "Best" for me probably means the fastest and most SEO-friendly option, but maybe there are other important factors (security, easier to configure and maintain...). Right now I'm using Apache, but for example for https apparently always checks the certificate of the old domain before redirecting to the new one, so maybe there are faster solutions?

Posted: 14 Jul 2022 07:58 AM PDT For development reasons I have both Postgres 12 and 14 installed on my local machine. However, often I also need to use the pg_dump utility to create backups. pg_dump 12 won't connect to a Postgres 14 database and viceversa.
If I simply run pg_dump, Ubuntu will use the one in /bin by default which is pg_dump@12. If I want to run version 14 I have to manually type: /usr/lib/postgresql/14/bin/pg_dump
Is there any way I can quickly switch between them? Something like: pg_dump@14
| | Are on-prem Windows Virtual Desktop servers still a thing? Posted: 14 Jul 2022 07:40 AM PDT My supervisor wants me to look into a virtual Windows 10/11 desktop solution leveraging our on-prem VMware cluster. Luckily, our cluster hardware has plenty of CPU/RAM/storage to accomplish the scope of the solution. The issue I'm running into is finding tutorials on how to set this up using Windows Server 2022-era products. All the solutions I can find seem to require an Azure tenant. I would have no issues recommending an Azure-integrated solution, except for the kicker: My company's Azure tenant is managed by a non-US corporation, to which we have no administrative access and getting an Azure VDI solution in place is so convoluted as to be effectively impossible. I know Windows Virtual Desktop is old tech and I totally understand why Microsoft is pushing Azure cloud services instead of on-prem solutions, but my situation dictates that I come up with an on-prem solution that will have the potential to last the next 3-5 years without Microsoft killing it with EoL support and security update cancellations. My question is two-fold: - Is Microsoft Virtual Desktop still a thing, and if so, where can I find some tutorials (preferable video-based, like YouTube) on setting it up?
- Is an on-prem, Windows-based VDI solution viable (even if you wouldn't recommend it over Azure, Horizon VDI, or Citrix) for the next 3-5 years (until my company gets with the times and moves to the cloud)?

Posted: 14 Jul 2022 10:51 AM PDT We have Microsoft hosting for exchange, office 365, defender for endpoint and are using the Office 365 MDM for device management. We only have Azure AD basic not premium. I've started an intune trial, created a Windows 10 VM as a device, added AD-based user, added the device and user to an intune group with policy and installed the company store app from the Windows store. In that app, settings > sync runs without errors. The device shows up in the intune device list and is compliant, but managed apps never sync. They are stuck at "Waiting for install status" My guess is this is because our MDM is Office 365, but I don't see any way in the admin panel or in any docs I've found to change that for just this test user, or the test device, or the intune group. Is there some way to force intune to be the MDM for just this user, device, group? Additional information: On the device, Settings > Accounts > Access Work or School shows the device as "Connected to (company) MDM" (which will be the office 365 MDM?) and "Connected to (company)'s Azure AD" In intune, DESKTOP-xxxxxx | Enrollment table shows "no results" for the device Is that significant? Joining AD and installing the company portal are both supposed to enroll the user or device if I'm reading the docs right. | | nginx reverse proxy - proxy_pass leads to 503 service unavailable Posted: 14 Jul 2022 08:37 AM PDT i have to following configuration: server { listen: 8080; location / { proxy_pass https://somehost.abc.xyz; proxy_redirect off; proxy_set_header Host somehost.abc.xyz; proxy_set_header X-Real-IP somehost.abc.xyz; proxy_set_header X-Forwarded-For somehost.abc.xyz; proxy_set_header X-Forwarded-Host somehost.abc.xyz; proxy_set_header HELLO pizza; } }
Whenever i hit the the proxy, let's say i go to http://localhost:8080/home , i get 503 service unavailable (not from the nginx service, from the app i'm trying to go to https://somehost.abc.xyz/home). But if i just go to https://somehost.abc.xyz/home or do a redirect return 301 https://somehost.abc.xyz/home; its all good and i get to the app. Although this doesn't help me, beacuse i want to get there through the proxy so i can add a request header to every request that goes through.

Posted: 14 Jul 2022 08:52 AM PDT I'm testing various GCP features and I've faced with the question in the title. After a little bit of experimentation I think the following should hold: - 2 peered VPC can not share the same subnet ranges, while VPC sharing is sharing the same subnets: if we want instances to communicate and we adjust firewall (FW) rules, does this make any practical difference?
- Shared VPC creates a hierarchical relation where one end is the manager of the network and FW rules and therefore can dictate all service projects abilities and can revoke shares, this also means that the host part must have access to service projects to let pick them and allow them to use the host project VPCs. Anyway VPC peering require a certain level of access to projects if one wants to peer them, but the 2 projects are on-par (both ends must allow the peering): this is an administrative/auth difference
- Shared VPC allows for a simplified FW setup as you have only one central point to setup your FW rules: you have the same set of subnets shared; while peering - alike VPNs - requires to setup rules on both ends: this is a management simplification
- Shared VPC can exhaust its resources (IPv4 ranges) faster but this means you have a ton of instances connected...
- VPC peering can do passthrou (daisy chain) up to 1 level: I've 1 connection from VPC A to VPC B and one from VPC B to VPC C. VPC A and C can not communicate but VPC B can communicate with both. On the opposite in a share scenario a project can only be either a host or a service at the same time but I can create a scenario with multiple projects sharing the same subnet and talk to each other transitively... this is probably the most relevant difference I've seen
Let say we have N different projects with N different administrators, if all parts agree on having some sort of network connection among instances, is there any other pro/cons in choosing peering over shared?! Edit - maybe this is the really biggest difference: if a service project uses a shared VPC and you later want to remove it, you need first to create a new VPC (or use the service project's default), reassign a new nic to all the instances which are currently using the shared VPC, let this new nic use the project own VPC, redo the FW rules and check for correct connectivity of all instances before detaching them from the shared VPC.
- additionally VPC peering can be used within the same project to increase the isolation between workloads but letting few selected VM communicate.
Edit 2 - As of now (2021-01) shared VPC can be used on a second NIC but it is a beta feature
- also one can not add more than 25 peering to a network, therefore it is quite common to let project communicate via shared VPC in so-called hub-and-spoke designs.
- Just discovered that VPC peering can be applied even between different organizations!

| | SMTP network ACL on AWS Posted: 14 Jul 2022 11:04 AM PDT I have a very restricted ACL for my VPC. We have a public subnet and a private subnet, each subnet has its own individual ACL. What I don't understand is why the following ACL works for sending email over port 465 via Amazon SES. public: - inbound: src 0.0.0.0/0, port 465
- outbound: dest 0.0.0.0/0, port 465
private: - inbound: N/A
- outbound: dest 0.0.0.0/0, port 465
I get both outbound, but the inbound for public doesn't make any sense. Where in the SMTP RFC say the smtp server (SES, a relay) will connect with the client back on port 465? I would expect client pick a high port as shown in the following netstat: tcp 104 0 ip-10-0-1-75.ec:36836 ec2-54-243-225-221.:urd CLOSE_WAIT tcp 0 0 ip-10-0-1-75.ec:50903 ec2-54-243-161-229.:urd ESTABLISHED
urd is 465 from what I understand. So my instance in the private subnet routes the request to the NAT instance, and the NAT (in public subnet) sends the packets to the remote server. So why is 465 needed inbound anyway? | | Sendmail and Gmail Posted: 14 Jul 2022 08:36 AM PDT I'm trying to send email with sendmail.

Thanks in advance.. | | Unable to bind OSX 10.9 to Active Directory 2008 Posted: 14 Jul 2022 09:00 AM PDT I am struggling to bind OSX 10.9 to a 2008 r2 Active Directory. I can join the domain fine when I boot into Windows from the same machine. From OSX I can find the domain controller successfully and have verified consistency of Active Directory service records (using dig -t SRV _service._tcp.fqdn.example.com to check _ldap, _kerberos, _kpasswd or _gc) but I cannot bind to the domain. I am attempting to join a small network with only one DC. I receive the message: "Authentication Sever could not be contacted. (5200)" This is the case whatever method I attempt to use (Join from the Users and Groups pref pane, Bind from the Open Directory utility, using dsconfigad from terminal). I don't think it is a problem with system time as the time on the client and DC are the same. Any other suggestions as to the problem or direction as to what to look out for in the log files? | | kvm guest can not connect to outside of host, vice versa Posted: 14 Jul 2022 09:00 AM PDT I have a vmware vm running ubuntu 12.04 server(name=vmhost), with network bridged and full access to the internet.

| Uncaught Error: Maximum update depth exceeded error with useState() Posted: 11 Jul 2022 04:05 AM PDT Why am I getting this error? Uncaught Error: Maximum update depth exceeded. This can happen when a component repeatedly calls setState inside componentWillUpdate or componentDidUpdate. React limits the number of nested updates to prevent infinite loops. This is my code: const [roles, setRoles] = useState([]); useLayoutEffect(() => { setRoles(["5nxg5wvb"]); });
Note that the same error appears when I use useEffect, and that error only goes away when I change the code to this: useLayoutEffect(() => { setRoles("5nxg5wvb"); });

Posted: 11 Jul 2022 04:05 AM PDT I've just integrated application insights into an application, and what is clear is that we are getting a lot of 401 error messages against an api layer. Looking at the way the sample code is written, its clear that it tries to call the service without even attempting to authenticate first, then uses the 401 to redirect to the login page, where it authenticates before reattempting the original request. Whilst is works, My question is, "Is this reasonable, and should I expect callers to authenticate before calling an endpoint"? from my perspective, it makes debugging distributed calls very difficult. The service architecture is overly chatty, and this makes it even more difficult to actually follow the callstack | | Display Form data on popup\modal when submitted in Angular Posted: 11 Jul 2022 04:04 AM PDT I have a form with submit button.

The matrix ends up with columns of ones and zeros. The goal is to have the indexes parsed from the strings of the matrix assigned to ones. I checked the debugger and the line result[x][y] = 1 doesn't execute with each forEach iteration, but instead assigns a 1 to each element of the y column of the matrix at the end of the forEach. const result = Array(N).fill(Array(M).fill(0));
Inside of a for loop: bitGraph.dfs(`${N - 1},${j}`, visited) .forEach(node => { const [x, y] = node.split(',') .map(index => Number(index)); result[x][y] = 1; });
Example: returned array: ['5,0', '4,0', '1,5', '1,4', '1,3'] result: [ [ 1, 0, 0, 1, 1, 1 ], [ 1, 0, 0, 1, 1, 1 ], [ 1, 0, 0, 1, 1, 1 ], [ 1, 0, 0, 1, 1, 1 ], [ 1, 0, 0, 1, 1, 1 ], [ 1, 0, 0, 1, 1, 1 ] ]

If I declare a variable as Int32, does it necessarily use all the allocated memory? That is, if my Int32 has a value of 1… Int32 myVar = 1; // binary 00000000 0000000 0000000 00000001 (4 bytes = 32 bits)
…then are all 32 bits used, or are they only used as needed when the variables value requires the bits? Seemingly, unless I used a low level language like C, C++, Rust, assembly, then Huffman encoding doesn't provide any compression of my data, albeit perhaps some very basic obfuscation of the original ASCII representation.

For this purpose I'm using debezium + kafka connnect, kafka and kafka streams.
For now I'm able to sync the changes perfectly to elasticsearch, including update, delete and create. But what confuses me is if my approach is correct and that if there's any other better way to do this. Here's my approach : - Stream changes for each table (9 in total) from DB to separate kafka topics using debezium + connect.
- In streams application, read those topics as KTable and join them to get complete doc.
- Write the KTable (output of join operation) to another topic and sink it using elastic search sink connector.
The reason I'm reading topic as a KTable is because it could happen that (say) some information regarding a specific record was modified after (say) 24hrs. If I read them as KStream then join operation will be windowed and that could cause issues. For example :
Let's say there are 3 tables, product, product_category, categories.
Then on initial sync things might work fine. But later on if another category was added for the same product (a new entry in product_category) after 24 hours. There's a possibility that the windowed join will not work if windowed option is set for 1 hr. And I'm not sure how KTable - KTable join works internally, is it efficient and will it scale properly for 8-10 Million records ? Also is it okay to create a new topic for each table ? I'll most probably have to join on all of those tables (9 tables in total). Any advice would be really appreciated :)
Let me know if some more information is needed.

Posted: 11 Jul 2022 04:04 AM PDT I need to show a preference dialog that wait for Joypad keypress. I know that DialogFragment has its own Window then has its own onKeyListener. I can easily catch Joypad press by setting a listener like that. public class MyDialogFragment extends PreferenceDialogFragmentCompat { @Override protected void onPrepareDialogBuilder(AlertDialog.Builder builder) { super.onPrepareDialogBuilder(builder); builder.setOnKeyListener(new DialogInterface.OnKeyListener() { @Override public boolean onKey(DialogInterface dialogInterface, int i, KeyEvent keyEvent) { // do stuff with intercepted key press return true; } }); } }
But, I have trouble catching GenericMotionEvents. In order to intercept them, I've overridden onGenericMotionEvents in the Activity class and eventually forward the Event by calling a method on MyDialogFragment class. It works 100% correctly when MyDialogFragment is not shown as when an analog trigger/direction stick is moved, I can get an event. The weird part is that IF MyDialogFragment is shown, then I can get only analog direction stick events BUT NOT left/right analog triggers events.

Posted: 11 Jul 2022 04:04 AM PDT How can I display this return in three columns on my web app, preferably with given headers? (FIGURED IT OUT!) THIS IS PROBABLY IMPORTANT! According to the writer of the gvizQuery function, which I use to find data in a referenced Google Sheet, the return is an array of arrays. Also, I now run V8 of Google Apps Script. So, this is the simplest version of the code where I provide a serial number, which is sent to the query function, and returned along with a reference to ou and most recent user. document.getElementById("btnserno1").addEventListener("click",fetchCBOU); function fetchCBOU(){ var sernum = document.getElementById("serial").value; google.script.run .withSuccessHandler(printCBOUU) .queryCBOU(sernum); } window.printCBOUU = function(CBOUU) { console.log(CBOUU); var CBOU1 = CBOUU document.getElementById('idCB').innerHTML = CBOU1[0]; document.getElementById('idCBOU').innerHTML = CBOU1[1]; document.getElementById('idCBRecent').innerHTML = CBOU1[2]; }
In the Stackdriver logs the return is displayed like this. Feb 17, 2020, 12:07:22 AM Info [[[5CD725B5B0, /Grundskolor/Boras, utd8377@edu.kunskapsskolan.se]]] This is what it looks like in the console. First a perfect match. 
On the web app it displays the three values in one place, and leaves the other two as undefined.  If I instead do a partial match, I get more arrays in console. 
But in the web app I get all those values in the first element and the two other elements are still undefined. If I manipulate the incoming data after it arrives, and try split it up, I get different results depending on if it's a perfect or partial match. I change the middle part of the code to this. window.printCBOUU = function(CBOUU) { console.log(CBOUU); //Creating the new variable, based off CBOUU, adding quotation marks. var str = CBOUU + ''; console.log(str); //Creating the new array, based off CBOUU, and now, since it has quotation marks, it becomes an array. var CBOU1 = str.split(","); console.log(CBOU1); document.getElementById('idCB').innerHTML = CBOU1[0]; document.getElementById('idCBOU').innerHTML = CBOU1[1]; document.getElementById('idCBRecent').innerHTML = CBOU1[2]; }
For a perfect match and a partial match that only has a single matching device everything still works. 
But if I do a partial match and get many hits everything breaks, as it is no longer working with variables with three sets of data, but instead as many values as there are matching devices, times three values. And to display them I'd have to keep adding CBOU1[n] values for each one. 
Do note that this is not static data! I'm trying to display the return from a function where I search for a partial serial number from a Google sheet. Logs (I thought this was an array, with three values for each object, but apparently this could be an array of arrays) [20-02-14 16:28:16:153 CET] [[[5CD9264KBW, /Grundskolor/Boras, user1@my.domain], [5CD9264K64, /Grundskolor/Boras, user2@my.domain], [5CD9264K7V, /Grundskolor/Boras, user3@my.domain], [5CD9264K6M, /Grundskolor/Boras, user4@my.domain]]
Console after I try to turn it into a usable array (here it looks to me to be a single array of only one object, with a bunch of values) ["5CD9264KBW", "/Grundskolor/Boras", "user1@my.domain", "5CD9264K64", "/Grundskolor/Boras", "user2@my.domain", "5CD9264K7V", "/Grundskolor/Boras", "user3@my.domain", "5CD9264K6M", "/Grundskolor/Boras", "user4@my.domain"]
My response to @Cooper who has tried to help me. When I try your code, @Cooper , like this. document.getElementById("btnserno1").addEventListener("click",fetchCBOU); function fetchCBOU(){ document.getElementById("idCBS").innerHTML = ""; var sernum = document.getElementById("serial").value; google.script.run .withSuccessHandler(printCBOUU) .queryCBOU(sernum); document.getElementById("serial").value = ""; } window.printCBOUU = function(CBOUU) { console.log('Device info: ' + CBOUU); // function splitItUp() { // using it as part of my code, with my return const data = CBOUU let a=data.slice(3,-2).trim().replace(/\], \[/g,'~~~').split('~~~'); let b=[]; a.forEach(function(r){b.push(r.split(', '));}); let html='<style>td,th{border:1px solid black;}</style><table>'; b.forEach(function(r,i){html+='<tr><td>${r[0]}</td><td>${r[1]}</td><td>${r[2]}</td></tr>';}); html+='</table>'; document.getElementById("idCBS").innerHTML = html; }
I get an error, as it can't work with the data. Uncaught TypeError: data.slice(...).trim is not a function
If I instead set data to what looks like my return and submits any serial. const data='[[[5CD9264KBW, /Grundskolor/Boras, user1@my.domain], [5CD9264K64, /Grundskolor/Boras, user2@my.domain], [5CD9264K7V, /Grundskolor/Boras, user3@my.domain], [5CD9264K6M, /Grundskolor/Boras, user4@my.domain]]';
Then it runs (doesn't use my input, of course) and this is what your forEach function looks like to me, @Cooper. As you can see it doesn't display the given data. 
The page.html section for where the result is displayed looks like this. <table class="striped"> <tr> <td><h6>Serial</h6></td> <td><h6>Device OU</h6></td> <td><h6>Most Recent User</h6></td> </tr> <tr> <td><h6 id="idCB"></h6></td> <td><h6 id="idCBOU"></h6></td> <td><h6 id="idCBRecent"></h6></td> </tr> </table> <table id="idCBS"> </table>
When I do get my many results to show here, I would, of course, like the headers to line up with the results. ALRIGHT, I NOW HAVE COME MUCH CLOSER TO A RESULT I LIKE! Now all the data is listed in columns. I borrowed some formatting suggestions from here, with a for-loop inside the array idea from another place to make the data display in a table, which probably can be done in several different nicer ways. Maybe even a way that will keep the alignment correct? This the current js. document.getElementById("btnserno2").addEventListener("click",fetchCBS); function fetchCBS(){ //This clears the results between searches. Else the html+= below will keep adding rows of data at the bottom. document.getElementById("idCBS").innerHTML = ""; var sernum = document.getElementById("serial2").value; google.script.run .withSuccessHandler(printCBS) .queryCBS(sernum); document.getElementById("serial2").value = ""; } window.printCBS = function(CBS) { console.log(CBS); var i,innerArray; var L = CBS[0].length; for (i=0;i<L;i++) { innerArray = CBS[0][i]; value1 = innerArray[0]; value2 = innerArray[1]; value3 = innerArray[2]; console.log(value1 + "__" + value2 + "__" + value3) // This creates the table in the idCBS spot. // Both <table> and <tr> bits can be removed, and result is still the same. let html='<style>td,th{border:0px solid black;}</style><table>'; html+='<tr><td>' + value1 + '</td><td>' + value2 + '</td><td>' + value3 + '</td></tr>'; html+='</table>'; document.getElementById("idCBS").innerHTML += html; } } //Code for the clearResults button document.getElementById("clearResults").addEventListener("click",clrResults); function clrResults(){ document.getElementById("idCBS").innerHTML = ""; }
It is displayed in page.html like this. <h4>Results<button class="waves-effect waves-light btn-small" id="clearResults">Clear Results</button></h4> <table class="striped"> <tr> <td><h6>Serial</h6></td> <td><h6>Device OU</h6></td> <td><h6>Most Recent User</h6></td> </tr> <table id="idCBS"> </table> </table>
This means I have the headers of the coming table visible before the search. But, since I use two tables, the headers aren't responsive, and don't adjust to the width of the coming columns which have wider values. It looks like this. 
If I try to put the headers inside the html+= creation loop in js, I of course get repeated headers. If I instead put the headers inside the idCBS table on page they are wiped by the early document.getElementById("idCBS").innerHTML = "" command. If I don't use and instead choose either or , then the data isn't looped properly, and is instead appended to the same row. Maybe I haven't tried all combinations, but I did try quite a few. I'm guessing there is a better combination of js + html to display my data in a perfectly aligned table, I just haven't found a solution yet. And, now I did! Changed the table code a bit, so I could move the idCBS to where it didn't interfere with the headers. <table> <thead> <tr> <th><h6>Serial</h6></th> <th><h6>Device OU</h6></th> <th><h6>Most Recent User</h6></th> </tr> </thead> <tbody id="idCBS"> </tbody> </table>
Columns now align! So, I'm good for now, but if anyone has suggestions for improvements, feel free to comment. I was shown that there is an alternative to moving idCBS. <table id="idCBS"> <tr><!-- table header --> <th>Serial</th> <th>Device OU</th> <th>Most Recent User</th> </tr> </table>
Then use: var myTable = document.getElementById("idCBS"); myTable.insertAdjacentHTML("beforeend", html);
But, if I don't move idCBS to then I can use my clearResults button, as it'll wipe the entire table. with idCBS in tdbody, the insertAdjacentHTML of course works fine there too. | | Duplicate notifications - react-native-push-notification Posted: 11 Jul 2022 04:05 AM PDT I have a problem with react-native-push-notification module on Android.

This works fine, but now I have to match authenticated user (from LDAP repository) with users from my database.

[closed] Posted: 13 Jul 2022 06:12 AM PDT Let's say that, through alien or divine intervention, something caused humans to be supernaturally unable to release any new hardware or make any new significant tangible (non-software) inventions from the day that Nintendo 64 was released world-wide. Any invention or hardware product that already existed at that date, however, can be built indefinitely in existing and maintained factories. (Including the N64 itself.) In such a world, would people have found ingenious software solutions to truly maximize the hardware of the Nintendo 64 and other then-current video game consoles and computers? With well over twenty years having passed since, and no new hardware to learn, would game developers have come up with all kinds of now-unthinkable hacks to enable breath-taking 3D worlds since they are not hobbyists homebrewing for a grossly outdated system, but highly paid programmers producing a steady stream of AAA titles with vast resources and accumulating experience? Is there really a "logical limit" that you hit in just a few years? I mean, look at some of the things that people made "in later years" for the Commodore 64. Same hardware as back then, and zero monetary incentive to do so, yet seemingly magical compared to what people assumed you could do with it when it was new/current.

I cannot restart or shut it down. When I try to use terminal it shows: NO LOGINS: System going down at 14:54 I logged out of my Apple ID and logged in again. However, it's still not working. I cannot use any buttons or applications. I only can use Siri to help start the applications. Anyone know how to fix it? Many thanks!

Screen static/garbage but only on internal display Posted: 13 Jul 2022 09:09 AM PDT I have a Early 2015 MacBook Pro Retina 13" which suddenly developed a very odd and specific issue earlier today. When running only the internal display under macOS, the display is unusable - multicoloured garbage and static, moving across the screen. Yet when I hook up an external display the problem disappears and both the internal display and the external one show macOS correctly. When rebooting and choosing the boot menu with only the internal display, all is well again. When loading macOS, it's fine until about two thirds of the way through the progress bar, and then the static psychedelic freakouts happen again and you can't even see the login screen. Again, hooking up an external display makes both displays work again, until the external one is disconnected (HDMI or Thunderbolt, makes no difference) When rebooting to Windows 10 Pro under Boot Camp, with just the internal display, everything is fine. If I load from a Gparted Live USB I have, also fine. If I boot a macOS installer, again fine, up until the point a clean install of macOS is performed. It was running Catalina, but I've also tried Big Sur and El Capitan (which is what it shipped with from new I believe). Booting to Recovery from any version of macOS, or Safe Boot, and no issues, perhaps because Metal GPU drivers aren't loading. Not sure. Having done fairly extensive testing before reaching out here, this leads me to believe it is a software issue with macOS because the internal Retina display clearly works. I'm wondering if it's related to Display Scaling because I usually run it at the "Look like 1440x900" setting and for some reason when booting macOS, the Apple logo and progress bar are smaller as if the scaling is applied from boot, and that's causing a macOS-only problem. I've looked for potential Terminal sudo commands I could use to try and force a display driver reset or some such, but have not found any yet. I've seen display faults on Macs before, but never anything like this. It's incredibly bizarre and specific, not a complete display fault across the entire machine, just macOS when not Safe Booted. Any advice please? I literally can't work out what the issue is. And I don't want to just use it in Windows 10; it's a Mac, I need it running macOS and it needs to work when not hooked up to another display to get around the issue. | | Wifi Drops when in Clamshell Mode Posted: 13 Jul 2022 05:07 AM PDT I have a MacBook Pro (13-inch, M1, 2020) in clamshell mode, connected to a 4k monitor and power through a USB-C hub.

What could be causing this? | | Use "startosinstall" to install macOS Catalina on External Drive Posted: 13 Jul 2022 01:00 PM PDT I want to use "startosinstall" so that I can install macOS Catalina onto an external hard drive in order to preload MacOS onto multiple SSD's quickly. I've researched into this and have found websites such as https://grahamrpugh.com/2018/03/26/reinstall-macos-from-system-volume.html which suggest using: /Applications/Install\ macOS\ Catalina.app/Contents/Resources/startosinstall \ --applicationpath /Applications/Install\ macOS\ Catalina.app \ --agreetolicense --nointeraction --volume /Volumes/External\ Macintosh\ HD
I've tried running the above but have had no success and always find that I get this returned: Usage: startosinstall Arguments --applicationpath, a path to copy of the OS installer application to start the install with. --license, prints the user license agreement only. --agreetolicense, agree to license the license you printed with --license. --rebootdelay, how long to delay the reboot at the end of preparing. This delay is in seconds and has a maximum of 300 (5 minutes). --pidtosignal, Specify a PID to which to send SIGUSR1 upon completion of the prepare phase. To bypass "rebootdelay" send SIGUSR1 back to startosinstall. --converttoapfs, specify either YES or NO on if you wish to convert to APFS. --installpackage, the path of a package (built with productbuild(1)) to install after the OS installation is complete; this option can be specified multiple times. --eraseinstall, Erase all volumes and install to a new one. Optionally specify the name of the new volume with --newvolumename. --newvolumename, the name of the volume to be created with --eraseinstall. --usage, prints this message. Example: startosinstall --converttoapfs YES
but can't seem to actually get anything to run. If anyone could provide me with some working code or show me how to solve this problem, I would be eternally grateful. Thanks for your help | | Can a Mail.app smart mailbox take *nesting* into account? Posted: 13 Jul 2022 04:01 AM PDT I'm using the fairly old version 9.3 of Mail.app on a computer running El Capitan; I just set up my Gmail account with it, and it seems to be correctly syncing. For organization purposes, I would love to have a smart mailbox that simply contains every message not in another specific mailbox (edit: that is, a folder), which I'll call A. The problem is that I don't keep any messages directly in A -- I keep them in A's sub-mailboxes (sub-folders) B, C, etc, and the sub-sub-mailboxes of those in turn. So the smart mailbox is not very useful. Is there any way I can make my dream a reality: A mailbox that only lists messages that are not inside Mailbox A at any level? | | Find string anywhere, not only at the beginning of words, in Safari on the iPad Posted: 13 Jul 2022 12:40 PM PDT In Safari on macOS one can choose whether to match a word that starts with the string or that contains it (see answer to Safari web browser do not find strings on a page in the common way). For example, if Find on page is set to contains, searching for "os" in this page matches the "os" in "choose", while if it's set to start with it doesn't. Apparently I'm stuck with "starts with" on my iPad, but I would like to match all occurrences, anywhere.

Posted: 13 Jul 2022 10:02 AM PDT When using Preview, I can create a text box to add text on top of a PDF. However, the text box is not always created in the correct area.

Thanks | | How to see count of unread emails from the Mail app in the Mac OS menu bar? Posted: 13 Jul 2022 08:04 AM PDT What's the best way to see the count of unread emails from the Mail app in the Mac OS menu bar? (Bonus points if I can use it to open the Mail app as well.) I don't really use the Dock, and I've gotten used to apps like Airmail and Fantastical that use the Mac OS menu bar to show information, like e.g. the count of unread emails. The best I could find after a quick search was https://www.macupdate.com/app/mac/22042/mail-unread-menu (from this thread), which looks like it hasn't been updated in ~6 years and might not work without also installing the MailPluginFix plugin. Is that really the best way to do this?
