I guess what counts as productivity depends upon what you want to produce. I need a web browser (Firefox) to learn about stuff and get it. Is there any reason to prefer one over another? I didn't know what inkscape is. Googled it (with browser). It looks like it might be fun to play with, but is it "productivity"? I have used gimp years ago, mostly to make party invitations with logo and map. I might have used inkscape if I knew about it at the time. Office, I have heard, can read Microsoft Office documents, which is something I refuse to do. Years ago I filtered out a lot of stupid spam by setting the SMTP server to reject anything with an attached MS-Word file. I think it still does that, but nobody sends them anymore. I'm hoping it follows Adobe shockwave flash web pages into oblivion. Besides the browser, my "productivity apps" are: -- emacs. There may be other ASCII editors, but how can one produce _anything_ without _some_ editor? -- gcc. I am interested in the Scheme programming language, but I need a C compiler (and make) to make the Scheme interpreter, and everything else. -- evince. A *.pdf reader. If I download a journal article, it's a PDF. -- TeX, LaTeX. To make my own article.pdf. -- Postfix, Apache. That's the way I roll. Others might think Facebook is a good substitute. Phltt! This conversation started with a link to a Video. How do you make a video? You get the raw material from a video camera/"phone", but what software should I use to cut and paste, maybe enlarge and crop? -- Keith

During TRIM testing, we managed to get an OCZ Vertex to spew I/O errors, and then finally fail to be recognized by the BIOS upon reboot. Note that this isn't a normal workload (the drive is being pounded on) and TRIM is still very new. So, I am not saying that the drives are not reliable in general. I simply don't know. Cheers, Jeff

Re: Software to write books

If you want to get it published or accepted as a dissertation, the deciding factor is what the publisher or school wants. If you just mean you want to write many pages and get them bound for personal use, I have gone to Park/Print in Worcester (very near my house) with a *.pdf file containing a math book, a Scheme report, or my own notes. They print it two sided 8.5x11 and bind it in a soft plastic cover and "comb" binding for short money. https://www.parkprintonline.com/ I have also gotten hard cover binding with title on the spine (back). I did this twice, once for my dissertation, once for some of my grandmother's writing. They cut it to the size you want. There was a place in Newton that did that, I don't know if they are still there. Chuck Anderson via WLUG <wlug(a)lists.wlug.org> writes: > Maybe you are thinking of LaTeX (pronounced La-Tech)?

Last meeting I tried the share-screen feature of jit.si and it worked. Tim asked "What's an idempotent monad?" or something like that. (It was in the title of the document on my screen.) I was not prepared to summarize a decade of grad school in a few seconds, and so did not answer. But if you promise not to ask too much about what it means, I could put together a few slides and demonstrations to show what it can do and how I use it.

Re: Ideas for the next WLUG meeting

by Joshua Stone

Tim, I'm glad you feel that way about it! The /sysroot upgrading process is one of my favorite features about Silverblue, as you gain some of thebenefits of COW snapshots without relying on a particular filesystem(example: https://github.com/openSUSE/snapper) GRUB is also enhanced where instead of selectinga different kernel, you're booting into an entirely different /sysroot complete with kernel, libc, drivers,firmware, etc. all of which are tagged under one discrete OS version string. This design shouldmake bug fixing a lot easier as a user may only need to attach the OS version string when filing a bugreport, and a developer could boot up that particular version inside a VM. This update model should alsoeliminate variance between "not updated" and "fully updated" like we see with traditional packagemanagement where a package mirror might not have synced all of the latest packages. The rollback mechanism is also quite innovative, which Silverblue can get for free by designing updatesthat perform the equivalent of `git checkout ${BRANCH}`. I'm sure there will be much to discuss when we get to have a demo. -Josh On Mon, 2019-11-18 at 13:45 -0500, Tim Keller wrote: > Josh, > I think this would be an awesome talk.

Re: [Wlug] Re: Next Meeting?

by Stephen C. Daukas

Is introducing yet-another-flavor-of-linux useful? I understand what you are trying to achieve, but one of the first questions that came to my mind was "what is the difference between Knoppix and a regular Linux distro"? (The first was actually "what the hell is Knopix"!) Will it be confusing to the people looking at is verusus what they see when they look at SuSe, Red Hat, etc.?

If things like that > exist, why care about encryption vulnerability? Because with properly configured wireless and patched clients, you can be sure you are connecting to the trusted network, not a Man-in-the-Middle. It requires mutual authentication, which happens for example on the WPI wireless network by using EAP-TLS certificates. The client is supposed to verify the server's certificate and the server of course verifies the client's certificate. Unfortunately, most networks don't use EAP but rather use Pre-Shared Keys (WPA2-PSK). > If you need to patch both sides to be secure, > then you are not secure in the coffee shop no > matter what you do.

In the strictest sense this is true, but as far as the KRACK attack goes, the wireless AP side is much less likely to be a problem, because the vulnerabilities are in parts of the standards that are not often used (802.11r "Fast Roaming" for example). The client-side vulnerabilities, especially in Linux/Android, are much more serious. On Linux, the client can be tricked into using a null session key. However, in a coffee shop KRACK is moot because most coffee shops don't use encryption at all to begin with. In any case, WPI's recommendation to use the VPN if you are not sure of your device's or the network's immunity to KRACK is sound, because even if there was a M-i-t-M, they still would not be able to decrypt the VPN traffic. Security is helpful in layers. Belt-and-suspenders.
