Re: What happened to libre office?
Minor item: The command for libre office calc is "localc", not "libreoffice-calc" (which might explain why the command isn't found). "man -k office" should list a few other options for you.

Re: linux based hex editor
I've used hexedit ('apt install hexedit' or 'dnf install hexedit'). It works
well and is terminal-based keyboard driven.
The keymap takes a little getting used to, but once you've used it a while it
works quite well.

Re: SD cards
Specifications set minimum requirements, rarely does a specification set an actual maximum limit. In this case, the specification requires that compliant hardware support *at least* the rates specified (within the defined optionality of the specification), but does not bar hardware from supporting higher rates or additional features, as long as the specification is met otherwise. Most likely the manufacturer is quoting the maximum possible rate for their hardware under laboratory conditions and using carefully specified supporting hardware; rather than the real world conditions with various unknown additional hardware elements (e.g. a card reader) and environmental conditions. Basically, you'll probably never see the maximum quoted data rate because some *other* hardware in the system probably won't support it (again, readers *can* support higher speeds, but most won't), but the card *could* deliver data at those rates in a theoretical perfect environment. Most quoted rates do, somewhere in fine print and often only on their website, describe the basis for the claim. With a little digging you can probably find the exact answer if you're curious enough.

Re: Software Portfolio
Some thoughts that may help (in addition to the good advice from Keith, Steve, and David). 1. Working on some open source software in Github is a good place to build a "here is what I have done" portfolio. Github has pretty good public analytics showing all your public commits and pull requests, as well as issues, reviews, etc... I've used github history to understand engineering skill, practice, and approach for both candidates and coworkers. 2. What to work on depends a lot on what you find interesting. If you want to work on Java or other JVM languages (e.g. Scala), I can probably make some suggestions (ping me off-list for detail) for open source projects to work on; if you can be patient I might be able to provide some *light* guidance on some of those. 3. The extreme majority of companies are terrible at interviewing. It's not entirely you that's bad at interviews; the company is probably about as competent interviewing software engineers as the average garden slug. 4. You can try an approach I've seen some people have good results with. A number of companies have started using things like HackerRank to (foolishly in my opinion) "test" potential hires. It's relatively simple to work through the "challenges" and "tutorials" on that site if you have time. Completing the majority of those both makes it simple to pass these "test" interviews (whether you know how to design software or not), and can also produce a large visibility boost if you want to find work with one of the companies that use the service for hiring. Side note (OT and rant, skip if not interested in curmudgeonly rants). Using canned "code challenges" as a pass-fail "test" is about the stupidest way to vet software professionals ever. High quality engineers are not faster programmers (and make no mistake, HackerRank is mostly based on "get the 'correct' solution fast"). High quality engineers produce designs that meet requirements better, are more secure, perform better, are more reliable, and/or cost less to maintain and operate. The fact is that people interviewing engineers don't know how to evaluate engineering skill so they fall back to "objective" tests, and end up filtering *out* the very people they want. I want to be clear, asking a coding problem isn't bad; provided the goal is to listen and observe problem solving, however, not get a "right" answer. Most people I interview never complete my coding problems; but I learn a lot about how they approach problem solving in the process. What's the alternative, though? I advocate dropping the "interrogation" style interview entirely. If you have to dig and manipulate to get truth from the interviewee, then you should not hire them at all; they cannot be trusted. Focus on a clear, honest, open, adult conversation and mutual learning instead. Ask questions about what the candidate can do, wants to do, interests, and expectations. Learn, both directions, if and how the candidate may meet the needs of the business, and if the position offered will meet the needs and expectations of the candidate (not everyone wants every position, nor should they). I have found, through hundreds of interviews, on both sides of the table, that an honest and open conversation is many times more successful than the typical approach.

Each file in the objects folders is an item (file, typically) in the repo. The
filename in objects is a hash.
The files are a differential format. You might check permissions (ls -l) and
extended attributes (lsattr/chattr) on that file to see why git doesn't like
that file.

This is a different error (different object) from the earlier error. This
time, instead of a file it cannot read, git is trying to rebuild the structure,
and is finding a file with an invalid gzip encoding (usually resultant from a
partial success on some earlier process, or failure reading from a remote
filesystem)
From the look of things, something is messed up in that particular object file.
You might check which "real" file it represents, copy the (likely binary) file
out of the repo, git rm the file, rerun git gc, then re-add the file to git.
If re-adding doesn't clear it up, perhaps push the repo to a different folder,
remove this clone, then re-clone from the other folder (or, if you already have
a remote, just push to the remote, remove the local, then re-clone from
remote). Sometimes that will clean up issues that don't respond to git gc.
Side note, git doesn't like binary files much. It can handle them, but most
git errors I see are related to binary files. Also, don't ever run git on a
remote filesystem, particularly samba (not sure if you are here, just noting
this in passing); git operations seem to make remote filesystems very unhappy,
and even a slight blip in filesystem driver can absolutely wreck the git repo
structure. I've seen a simple git fetch on a samba mount generate a few
thousand samba error files, and utterly destroy the git repo (requiring a
re-clone).

Re: git can't read file
First step is remove the git.log file, run git gc, and see if the error returns. The missing file issue can be transient, but can also be a case of file corruption; often due to using a remote filesystem that has synchronization issues (e.g. SMB). If the error returns after removing the log file and rerunning git gc, then you can look for that file in the .git folder structure and see if there's a filesystem lock, file permission issue, or something similar blocking git from reading and modifying the file.

Re: Why "no such file" error ??
I know it seems simple, but have you checked permissions to ensure the user ID running the script has both read and execute permission for the executable, and the extended attribute noexec is not set on the executable? I've seen that error when permissions are not quite as expected, or when extended attributes are set to prevent an action... Another possibility that comes immediately to mind is whether there is a symbolic link in the path to the executable, symbolic links can get weird at times. Third question, Did you copy over the binary, or recompile the program on this new machine? If you did copy an existing binary, a recompile might be a good idea to rule out issues caused by ELF or glibc changes.

Re: Invalid Context= error
I've seen things like this after an upgrade. A couple items seem to be happening. 1) The Hebrew language package is missing a file hunspell expects. Ubuntu installs a stack of languages on every upgrade, even if the original install removed them. If you need Hebrew, you might want to manually reinstall, if you have no need of Hebrew, it might be easier to remove (and purge) it. 2) It looks like the Mint-Y icon theme is missing or moved. Reinstalling the theme and/or switching to another theme, then switching back, should resolve these errors.

Re: Boot up from cold boot no network
I've discovered a similar issue just yesterday. I hunted it down and found that the cause, for me at least, was in the static NetworkManager configuration. NetworkManager configuration now marks *all* interfaces as unmanaged *except* WiFi and Cellular, basically all non-wireless interfaces are prevented from being activated. Apparently some genius at Ubuntu decided nobody uses wired connections. In /usr/lib/NetworkManager/conf.d/10-globally-managed-devices.conf, check the line that starts with "unmanaged-devices". If it reads as follows, consider modifying or commenting out the line. unmanaged-devices=*,except=type:wifi,except=type:gsm,except=type:cdma If you make changes, run "systemctl reload NetworkManager" to update the running daemon.

Re: Gimp
Mike, It looks like what you are trying to do is merge three photos with different exposures into a single photo with greater dynamic range. That's usually described as High Dynamic Range, or HDR, exposure. There are tutorials online for how to do that; a search for ["High Dynamic Range" GIMP] should bring good results.

Looks like an attempt to create an alternative to the Linux kernel that is single process and has no users (check their github at https://github.com/nanovms/nanos and related https://github.com/nanovms/ops). There may be some value to that, but things like CoreOS and Project Atomic make that value narrow. Their approach is designed around a single-process approach that isn't common for modern server systems, including in containerized designs. The NanoVM approach requires a full VM as well, which provides more cross-process isolation, but also dramatically increases overhead. Even the simplest system usually requires at least a couple daemon processes to handle things like log shipping or process monitoring. Sometimes other containers can fill those roles, but that doesn't work if each process is a full VM, rather than a container. They seem to be doing well making this open-source (Apache 2.0), but it's not clear if the company is committed to remaining entirely on an open-development path. Overall it seems somewhat niche, and they may find their business plan is not as effective as they hope.

Re: Domain Registering and Hosting/Website Funny Business
TL;DR Have your friend contact GoDaddy, ideally by logging into their existing account and contacting support from there, and request they delete all content as you no longer control the site and they no longer have any right to continue serving that content. Most likely, the new owner simply didn't make any change to the name server entries when they bought it (domain gamblers tend to do that a lot). Basically, the name still resolves to the same site host, and the purchaser is waiting for your friend to beg them to "return their domain" so as to keep the site (and presumably the business) running. Some just kind of wait for contact, others will wait about 90 days, then send email to the website warning of a deadline and demanding heavy payment to not redirect it to a parking page or something similar. A lot depends on who the host provider is. If, as in this case, the host provider is the same as the domain provider (side note, don't do that in the future; always separate the two so nobody controls both but you), then you may have some issues, but at least in theory your friend can, at minimum, ask that the hosted content (which they still own and on which they hold copyright) be removed. If the host provider is separate from the domain provider, then you could either arrange back payment and regain control, then point a new domain to the site, or ask the host to remove the content (again based on ownership and copyright). In this case (with GoDaddy hosting both), I hope your friend has backups of the site and can redeploy elsewhere, and I hope GoDaddy does the right thing relatively quickly (sometimes they can be difficult in this regard). This doesn't apply in your case, but one other, somewhat ugly, possibility does exist. Some host providers use a domain challenge to identify the site owner if they lose access otherwise (they have you put a code in a dns record to prove you are you). Those are particularly pernicious as anyone with control of the domain actually can steal the site and content by claiming to have forgotten a password (which can result in theft of an entire business identity for purely online businesses, and is a form of identity theft). Always worth checking if your hosting provider uses that option, and ask them to either administratively disable that (permanently), or move to a different hosting provider (assuming you can). Note: Domain challenge to prove ownership of a domain, separate from ownership of the hosting account, is totally normal and reasonable, I'm referencing here using domain challenge to prove identity and ownership of the separate hosting account. Hopefully that helps. Joseph Sinclair P.S. The domain origination date does not change unless the domain is returned to an unregistered state. When a domain is auctioned, it is never "unregistered", the registration simply transfers after GoDaddy takes over the registration for non-payment.

Re: Should an opensource dev know Linux
Call me biased, but, in my opinion, all software engineers (and programmers/coders too) should know, or be learning, *at least* enough about Linux to: edit and build their software at the command line configure and script an automated build (using a common tool like jenkins, Github actions, or any similar system) define a dockerfile and build a docker image with podman run a docker image with podman and CRI-O, runc, and/or Containerd. That said, I find where I am now I have to allocate about a month+ for every new hire to learn at least that much, and most take much, much, longer (thanks to poor decisions by executive management we're mostly hiring junior devs, overseas, at the low end of the pay spectrum, though, so even base skills are pretty shallow). Some know a bit of shell scripting and may be aware of Linux, but very few software engineers I encounter at work actually run Linux routinely. As to the resume bit, depends on who is hiring. If it's someone like me, it's going to help. If it's some clueless MBA who has only ever used Windows and makes tech stack decisions based on the latest Microsoft .Net features, perhaps not.

Re: Scripting/automation method/language
A lot depends on complexity. A few questions: 1) Is this easier to understand, or harder to understand as Bash 2) Is it more or less work to maintain as Bash versus a more general purpose language 3) What options exist for general purpose languages to accomplish the task Depending on answers to these, you might stay with Bash, if it's not too hard to follow and not too much more work to maintain. If you have large and/or complex processing, you might want to use something like Perl (which is a required core system dependency for most distributions), Awk, or Python. Depending on other software routinely installed on the systems, you might also have the option to use Go, or anything that compiles to LLVM. You might also find that Python is already installed; perhaps just with the binary named python3 or similar. I don't know of too many distributions that don't require python currently. You might also package the scripts with any required dependencies (languages like Python or larger toolsets like Ansible and Terraform) in a container, and run the contained package in open mode (e.g. like a flatpak) on the destination system. This has the added advantage that these management scripts can be read in, executed, then removed cleanly as needed; reducing the need to keep yet another item up to date on the machines.

Re: krita, acer, samsung
Some things to note: The NVMe drive in the Acer will significantly improve startup and disk access, it's about 4-5 times faster than an SSD. The extra RAM in the Samsung, as well as the more capable i7 CPU, will make the general "feel" of the machine smoother and faster while in use. The Samsung with the 8th gen i7 is not a good choice. Ideally one would add an NVMe to the Samsung 12G ($120 gets you a Samsung 1TB NVMe in an 80mm M.2 form factor), but lacking that (I do not think the Samsung Ion, guessing that's the machine, has NVMe M.2 available) All else being equal, I'd probably opt for the Samsung 12G, or the Acer if startup time is more important than working with larger art images. Note that 8G RAM (including O/S) limits drawings to about 8K resolution, max, at high color depth, and while that's good for screen, it might not do for anything intended to be seen on paper or canvas. One other thing, It might be worth taking a look at the Wacom Cintiq panels if your wife is interested in high quality digital art. It's a very good drawing tablet under a high quality (USB connected) screen that can attach to just about any laptop or desktop. A bit pricey (16" is ~550; Wacom One 13" is ~400), but hard to beat for someone with significant skill or talent who is transitioning from Analog to the digital world.

Re: Why I hate updates ... Thanks Michael ...
Joe, I would recommend running a couple simple cleanups to get some space back for now. Keep in mind this will be a temporary fix; you will run out of space again fairly quickly if you cannot remove some programs or otherwise permanently clear some space on the root partition. Empty the trash/recycle folder Remove old kernel versions (I recommend keeping the most recent two) Remove less commonly used fonts sudo apt purge "fonts-kacst*" "fonts-khmeros*" fonts-lklug-sinhala fonts-guru-extra "fonts-nanum*" fonts-noto-cjk "fonts-takao*" fonts-tibetan-machine fonts-lao fonts-sil-padauk fonts-sil-abyssinica "fonts-tlwg-*" "fonts-lohit-*" fonts-beng-extra fonts-gargi fonts-gubbi fonts-gujr-extra fonts-kalapi "fonts-samyak*" fonts-navilu fonts-nakula fonts-orya-extra fonts-pagul fonts-sarai "fonts-telu*" "fonts-wqy*" "fonts-smc*" fonts-deva-extra fonts-sahadeva Remove unnecessary apt files and unnecessary library dependencies sudo apt-get clean # this will gain a good amount of space, but it will fill back up with the next apt update or apt upgrade sudo apt-get autoremove --purge # this will remove packages leftover from other programs and no longer needed, --purge just makes sure the related configs and help files are also removed, cleaning up space in /usr/share and /usr/local/share Check logs in /var/log, if there are some very large files (or a large number) that are compressed (old logs are typically compressed automatically), you might consider moving those to an archive folder in /home where you have plenty of space. I don't recommend removing old logs arbitrarily. Look at /tmp, /var/crash, /var/spool, /var/cache, etc... See if there are large files you can move to a folder in /home or (/var/cache) remove. sudo du -ms /var/* | sort -n # This will list folders in increasing size order, the largest at the bottom are good candidates to clean up, size is in megabytes, so anything over 500 is a good place to see if you can clean up. Look at what you have installed (something like Synaptic helps here) and see if you can remove rarely used, but large, applications (use apt purge to remove them, so the config and support files are removed as well) The typical Mint install includes a lot of software, some of that may be things you never use. Try to find large applications (things like Evolution, or Banshee) that you do not use, and remove those. As others have mentioned, you need a larger root partition eventually, but the steps above should help you clear enough space temporarily to limp along until you can accomplish a more permanent fix. Hopefully that helps you get to a more stable state. ==Joseph++ P.S. This isn't relevant to Linux Mint 17, but is relevant to newer systems: Note that /var/log/journal often has a very large amount of old logs in modern systems. This is the systemd journal, and has it's own commands for cleanup: sudo journalctl --disk-usage # Show how much space the journal logs take up, in one of my systems this is over 6G. sudo journalctl --rotate --vacuum-time=4weeks # rotate the journal files, and remove any older than 4 weeks; this will typically clear around 2-4G of space on systems that have been running a long time. Note that you can also configure journald to rotate and remove old logs automatically, this is configured in /etc/systemd/journald.conf. I recommend reading the relevant documentation before making changes there.

Re: C on Linux or all of Java?
C and C++ are mostly used for shrink-wrap applications and libraries. The Linux Kernel is still C and the Windows Kernel is mostly C++. About 90% of business applications are Java. It's the most widely used language and platform for web-based applications and microservices. The Spring platform is very popular, but I'd actually recommend looking at Eclipse microprofile (microprofile.io, quarkus.io for a good implementation) for microservices, it's much lighter and faster. Node.js is popular with "full stack" shops. It's very quick to pick up, but extremely difficult to build non-trivial systems and maintain them. The single-thread nature of the system and dealing with javascript async constructs can be particularly difficult. For desktop applications in JavaScript (not ideal, but some entities want this) there is the Electron framework. Microsoft likes this a lot, and some major Microsoft applications, like MS Teams or VSCode, are written in Electron. If you're looking to develop systems for Windows only (unlikely, but possible), then .Net and C# are widely used. Mac is kind of a grab bag, but Objective-C is still pretty popular. A lot depends on what one wants to learn and why. Just learn something? Perhaps Java as it's very widely applicable. Learn something as a challenge? C++, it's probably the hardest to learn to do well, and can build extremely complex systems. Learn something quickly useful? Go, Python, or Node.js. These are popular, quick to get started, but you have to be aware you can design yourself into a corner very quickly, and maintenance can get difficult. Transition from PHP to more general-purpose systems? Go is a good place to start; it's designed from the ground up as a language for new or transitioning programmers. It requires you follow very strict rules, including an enforced style guide, but it's also easier to write "correct" code than most alternatives. Other goals might point to other alternatives, it all depends on the purpose.

Re: question about Java
Ed, thanks for correcting me. OpenJDK is GPLv2 with classpath, not GPLv3 as I had asserted earlier. TL;DR: The technology isn't what makes (most) systems good or bad, the engineering is. I like, and work with, Java, Javascript, Python, Go (granted, the style guide there is unpleasant), and C++. I've even held my nose and worked on .net code a couple times. I am familiar with several other options and toolsets (and really like some that just aren't quite popular enough for enterprise use, like Scala). I've seen good engineering in most technologies, and bad engineering in all of them. I've been creating systems with Java for a rather long time. The only versions of OpenJDK I ever had issues with were 5 and 6, which lacked a couple of items that were closed-source and had to be replaced (in version 7 they were replaced with open re-implementations). I've seen some code, written objectively incorrectly, that depends on internal API's of the JVM and, technically, violates the license terms as those classes are specifically called out as not licensed for use. That software won't move from version to version well, or at all, because it's using internal details instead of published APIs. I've also excoriated more than a few lazy-bum (I'm being extremely kind here) "programmers" who insist on using those internal API's because they cannot be bothered to take 10 minutes and look up the standard API equivalent (or bring in a common library for that functionality). I've worked on a LOT of Java code, and while it's far from the only language I use (I currently work with 3 *regularly* at work), it's one of the most productive for me and most of my teams. For modern cloud-native systems it's one of the best options in many situations. (although, please don't mention the abomination called Springboot; that's the real zombie godzilla that needs to die). None of this is to say Java is somehow superior to all comers. More this highlights that good engineering is far more important than the language or platform in most cases, and that even for the same language bad engineering or a bad platform choice can make a huge difference. BTW, lest you think compatibility only works in demonstrations, I ran a test, just for funsies, on all 18 microservices we have in production to run these Java 8 or 11 systems on Java 14 (pipeline builds help here) and loaded them in dev containers to check compatibility. None had any issues at all. If we didn't have policy limitations to LTS versions, I'd probably upgrade them all to 14 in production, as it does improve several performance metrics by a bit. Yes, there is a lot of lousy engineering in enterprise, but it doesn't matter what platform you pick. Bad engineering happens, and tends to stick around a long time because it costs too much to redo. That doesn't mean the foundational technologies are good or bad, only that the use of them was. P.S. I just took a quick look at JBidwatcher, I've seen worse code, but only in contests to write bad code. That thing may meet a valuable need for people, but it is truly terrible from an engineering design standpoint, I'm not even a little surprised it is tied to very specific VM builds. It uses internal JVM classes all over the place, even when there are better choices in the standard library. It's almost like they designed it deliberately to prevent portability.

Re: question about Java
Mike, You are running Java 11, which is the current Long Term Support version for Java, and preferred for most uses. If you're running software that isn't horribly outdated and badly designed (and there is some of that) it will run on your install just fine. If the ImageJ2 software is still talking about a transition from Java 6 (circa 2006!) to Java 8 (circa 2014), they're sufficiently far behind as to be dangerous. There are known unpatched vulnerabilities in Java 8 that make it unacceptable for use in a desktop environment. That's part of why all of the distributions have replaced it with Java 11 by default. You could upgrade to Java 14 for the very latest VM improvements, but it's not a particularly big deal unless you're writing Java software or running Java in the server realm.

Re: question about Java
Sorry, Michael, but this is complete bunk. On 2020-05-04 11:29 AM, Michael Butash via PLUG-discuss wrote: > Again OpenJDK and OracleJRE are totally different - including version > numbers. If someone says "works with Java 8", they 99.9% of the time mean > OracleJRE and their versions, and theirs only. Oracle JRE or JDK is a repackaged OpenJDK build, and nothing more. The version numbers are identical. The code is identical. The build process is identical. The only thing you get with Oracle builds is the *option* to pay for Oracle commercial support. In fact, any package in any Linux distro labeled OpenJDK is generally a packaging of the Oracle build, which is why OpenJDK 8 builds are no longer available easily, as Oracle pulled Java 8 to commercial-only support last year. > > OpenJDK is only ever used with, well, I don't even know anymore, as > everyone Open Source moved on to hate Java, Oracle, Larry Ellison, etc. OpenJDK is, and has always been Open under GPL3 If you want fully open and community (or commercial from not-Oracle) builds of any recent Java version (8+) you can get those from adoptopenjdk.org, which is a consortium of large and small companies that are supporting continued open access to the GPL3 source code and builds of the Java system. A huge amount of the internet is running OpenJDK, and a vast array of systems are transitioning to the adoptopenjdk builds simply to ensure continued access to support from multiple vendors. > You can pretty safely remove/forget OpenJDK as an end-user at this point I > think, unless something specifically mentions needing it. If you're running Linux, and you need Java, you should be installing the OpenJDK package from your distribution, if nothing else to ensure continued and frequent updates along with the rest of the system. If there is an option for adoptopenjdk for those packages, that's a good choice, but the builds from the distribution for Java are made from the official codebase that underpins all builds, including Oracle's. > > -mb > Joseph Sinclair > > On Mon, May 4, 2020 at 11:24 AM Michael wrote: > >> Thanks for the tip! >> So then looking at it it looks as if I have Java 11 installed.
