suggestion: naming temp files
by D. Hugh Redelmeier 18 Apr '18

18 Apr '18

I often want temp files. Putting them in /tmp means that they will automatically be discarded on reboot -- kind of handy. But it means that they are public: they are in a space shared with all other users (if you have other users). I consider it a bad habit for that reason. Lots of people put temp files in the current directory or in their home directory. That's what I do. But then, when you come back a week later, how do you know that this file is garbage? The best way is to have a naming convention. Many people use tmp, tmp2, tmp3 as names. I find those visually too like real filenames and longer to type than I want. The names I use are 0, 1, 2, 3. They are short, distinctive, and unreasonable as permanent filenames. You can find the litter you left behind with: locate -r '/[0-9]$' You will notice that the system does have some files that match too so you cannot blindly delete all matches. To me, it is obvious. But I didn't think of it. I copied this from Chris Sturgess almost 30 years ago.

VM decisions for school laptop..
by Michael Galea 13 Apr '18

13 Apr '18

Hi All, My son is off to university for CS this fall, and will need a laptop. I'm looking at purchasing one for him, so he can run Windows and Linux. I'm figuring on going the VM route. He can use both OS's but is probably more familiar with Win, and his courses mandate a number of windows only tools. I'm heading in the direction of booting Win10 and using a VM running Debian. A bit of research indicates that the two most popular free VM contenders are VMware and Microsoft's Hyper-V. Can anyone recommend one over the other? Are there better choices? As per laptop specs, I am figuring on getting something with a late model Intel i7, 32 GB RAM, and 1-2TB storage. I figure many laptops must meet this spec. Is there anything else I should be looking for? -- Michael Galea

USB 3.2 - Display Port symbol is a styalized P
by Russell 12 Apr '18

12 Apr '18

I found a logo for a Type-C USB 3.2 device having DisplayPort capability online. The USB 3.2 hardware is scheduled for distribution sometime in 2019 As Mailman drops image attachments from messages to this list, unless moderated I think, I can't show the actual logo. Here is my symbolic glyph description and my notes, for when I go looking for this hw. SS =~ ( +/+ P [: : : ...] The logo image I saw from USB-IF has two outlined upper case S's followed by the usb trident and a half sized open brace. Next comes two stacked (one over the other) + signs and an outlined upper case P. There is some sort microsized image on the label near the brace, but it is too fuzzy to see in the low resolution image I saw. Finally there is the port itself. -- Russell

does anyone know how to make CentOS 7's PPPoE client handle IPv6?
by D. Hugh Redelmeier 10 Apr '18

10 Apr '18

I have a DSL account with Teksavvy. They claim to support IPv6 on DSL. https://help.teksavvy.com/hc/en-us/articles/205837513-IPv6 I'm using a CentOS 7 box with Roaring Penquin PPPoE to connect. That's worked fine for a couple of years. But only for IPv6. I would like to enable IPv6 because BIND, my nameserver, is trying to access some IPv6 things and is failing. Does anyone know how to enable IPv6 in this situation? Almost as good would be convincing BIND that it should not talk IPv6. I'll need to do this anyway on another gateway at another location. It is hooked up via an ISP that doesn't support IPv6.

Really funny email from Microsoft
by D. Hugh Redelmeier 06 Apr '18

06 Apr '18

I got email from Microsoft. Maybe you did too. Subject: URGENT—Action needed before April 10 to help protect your PC Your final Windows 10 security update is on April 10, 2018 ... It sure looks like a scam but it really is from Microsoft. It is very badly worded. - it really only means that an old version of Win 10, "Anniversary Edition" will receive its last update on April 10 (one year after release). This explanation is nowhere in the email -- I had to infer it from googling. This is no big deal because the updates system will automatically take the system to the newest released version anyway. Well, it will try. The Windows Update system regularly chokes on my small systems. Mostly because Microsoft mandated 2G RAM and 32G disk for cheap licenses and update does not reliably work within those resources. Its failure modes are various, pathetic, and undocumented. - the message does not tell me which of my systems are still on old versions. I have lots of systems with Windows licenses that barely get used. Oops, in the HTML salad of the email was a link to a web page showing the status of all my devices (but it doesn't highlight the ones "at risk"). My major use-case for Windows on those machines is updating Windows. A secondary use-case is updating firmware of systems whose manufacturer is smart enough to release firmware updates but dumb enough to require Windows for those updates. - if the final update is to be released on April 10, should I not update on or after that date, not (just) before? In no way is this my final Windows 10 security update unless I scrub Windows from my systems. Or something more important ends (me, Microsoft, the world, ...).
