Re: How does Linux handle DST/ST? It's all about time...
If some variation of that sleazy hack doesn't work and you can't find some some source for the info you want (maybe something like https://isDSTactiveInMyTimezone.com/ :) then you'll have to determine if DST is active on your own. That requires a timezone file for your locale and some source of "current UTC time"; your system clock chip can presumably supply the latter. Here's hoping you can find existing code (like a Python library) to paddle around in timezone files. If not, you can dump a timezone file with zdump; the output shows (among other things) the exact dates/times of transitions into and out of DST, as well as your locale's offset from UTC after each transition. The timezone files typically live in /usr/{share,lib}/zoneinfo/ The timezone file governing your system is specified in /etc/timezone So, on my Ubuntu system this command dumps the current timezone file: zdump -v /usr/share/zoneinfo/$(cat /etc/timezone) ...in a text format that could be parsed to discover if DST is in effect in my timezone.

Re: How does Linux handle DST/ST? It's all about time...
You can mess around with DST and such but this slightly sleazy hack might serve an alternative: find some way to get your "dumb" machine to tell your "smart" machine what time it thinks it is currently, and then force the smart machine to that time. For example, if SSH works from the smart machine to the dumb one then from the smart one you might say: % x="$(ssh dumb date)" % sudo date --set="$x" ...or some variation on that theme. --M ___ gnhlug-discuss mailing list gnhlug-discuss@mail.gnhlug.org http://mail.gnhlug.org/mailman/listinfo/gnhlug-discuss/

Re: tech recruiters you like?
I shouted with joy when it was announced that the completely vile practice of prospective employers demanding that you reveal your compensation history will (at least in MA) become illegal next year: http://www.nytimes.com/2016/08/03/business/dealbook/wage-gap-massachusetts-l aw-salary-history.html ...and even though it's reported as being intended largely to defend against gender discrimination it is *long* overdue in all cases. Our skills/abilities/services have a market value and it's arrogant for a prospective employer to attempt to decide what's "proper" based on whatever our previous circumstances were; if I was overpaid in my previous gig it's not their responsibility to perpetuate that error, and if I was underpaid they are not somehow entitled to continue the punishment, either. I'm mentioning this because in my experience headhunters/ recruiters ask early and often for lots of sensitive info about a candidate's circumstances (not just compensation) while offering as little as possible in return. This new legislation applies directly to them because in many cases they end up being your employer in contract situations, even though it's easy to forget that because you may never lay eyes on them or their place of business. I've had some success deflecting rudely inapprpriate questions along these lines by ignoring them and countering with: What do you know about the client? Do you have an existing relationship? What do you know about the hiring manager(s)? the team? [ Too often, they only know what they've scraped off the prospective client's WWW site, ie. nothing... ] What's their budget? What rate would you intend to charge them for my services? What rate are you offering me? How do you account for the difference?" ...etc. Obviously, every situation is different; sometimes we're in the driver's seat and sometimes we're nearly powerless, often it's a distasteful mix. --M ___ gnhlug-discuss mailing list gnhlug-discuss@mail.gnhlug.org http://mail.gnhlug.org/mailman/listinfo/gnhlug-discuss/

Re: Chromcast

I received a Chromecast as a gift but haven't messed with it much; I, too, am disappointed but not surprised at Google's refusal to support Linux users. I think the Chromecast device for the most part (we'll ignore "tab-casting" mode for now) operates independently, pulling content directly from providers like YouTube and rendering it on your TV via HDMI. You tell it what to stream using commands transmitted locally via WiFI from a Chromecast-enabled app (I'll call that app the CA) running on something like a Windows or Android machine. I think the CA can only (using something like the DIAL protocol) discover Chromecast devices that have associated with the same WiFi Access Point, though an interesting question might be: will a CA on my laptop still work if I disable WiFi but remain connected via wired Enet to the same LAN the Chromecast is on? I'm guessing there are no CAs for Linux because Google needs the CA to be easily able to comandeer the WiFi connection on its host platform, and there are too many variables involved in doing that on the average Linux box. > I must switch to Windows Vista on this computer to cast.

If it's a named pipe any writes to it will block until somebody opens it for reading and if they subsequently close it the writer will see an error (SIGPIPE?) that it'd better be prepared to handle.

I don't know what the current crop of WD Desktop drives is like but when I was evaluating them for inclusion in a product about 4 yrs ago they didn't make the cut.

Their stylish pedestal package had blinkenlights and a dramatic sci-fi appearance, but the center of gravity was so high and the pedestal's footprint so small that they tipped over given the slightest nudge. Also, they offered no (or too little) control over the permanently enabled power-saving "feature", the device taking long enough to spin back up and become available that it was sometimes abandoned by the kernel as faulty.

911 calls from unsubscribed devices
My understanding is that mobile phone service providers are required to transmit/relay all 911 calls regardless of whether the originating device is registered/subscribed to the provider in question. If so, what kind of (preferably minimal and unobtrusive) HW/SW would a generic laptop (running Linux, of course) have to be equipped with to exploit that requirement to have a basic 911 Panic Button capability? I assume that, ideally, a 911 operator would like to have a conversation with the caller to better assess the nature/urgency of the emergency, but I also assume that's not strictly necessary as long as location info is included in the transmission, as obtained either via GPS or tower-triangulation. ___ gnhlug-discuss mailing list gnhlug-discuss@mail.gnhlug.org http://mail.gnhlug.org/mailman/listinfo/gnhlug-discuss/

I haven't worked with ClearCase in quite a while but have done so at several different companies.

We even kept the tool chains in ClearCase so we'd be sure to have all the correct compilers and stuff for recreating ancient builds. - I liked (what we used to call) The Wayback Machine aspect where you could easily fall back to whatever versions were current at any particular time - useful for quickly finding when something got b0rken. - I liked the ClearCase-aware make that could determine if (as was often the case) a given target already existed in somebody else's view and, if so, perform a "wink-in" instead of having to build it locally.

Picky, picky, picky. Well, for completeness I suppose we should mention the "deleted file" trick (not necessarily better than your flock trick) where your app creates its secret-squirrel file in /tmp and then deletes it while holding it open. (This trick is popular with malware eg. the Flash plugin) Your confederates can identify likely instances of your app using ps and then verify by reading the secret-squirrel file via the symlinked handle in /proc/$yourPIDhere/fd. Since the file has no directory entry it can't be deleted by friend or foe and only those with appropriate privileges can access it as described, and all traces vanish upon process termination.

Re: Files, unliking, access, oh my.
>Can that space that the file takes up be overwritten during >this interim? Or does the OS hold the inode sacrosanct until >both references AND processes are no longer making use of it? Right - the OS's official record of a file's state is the (in-memory copy of the) inode - the directory entries are simply tags. Once a file is opened the kernel's relationship with that file is entirely via the inode and deletion of one or all of the corresponding directory entries has no effect on that relationship, which persists until the refcount goes to zero, ie. all procs that had it open have closed it. Only then will allocated disk space be released and eligible for reuse. ___ gnhlug-discuss mailing list gnhlug-discuss@mail.gnhlug.org http://mail.gnhlug.org/mailman/listinfo/gnhlug-discuss/

Still safe to nuke it. When you say "nuke the connection attempt" do you mean kill the process that's attempting to open the connection? I can't, because it's an inbound connection and that process is (apparently) somewhere inside Facebook. I only have control over the response at my end which, in my case, is nothing at all since the port is blocked, with failed attempts logged as shown. An nmap scan of the machines behind my firewall currently shows nothing (legitimate or otherwise) listening on port 443, so I don't have any suspects to "nuke" at the moment here inside the walls. I was mostly just wondering if these connection attempts are examples of some intentional Facebook behavior, or whether I should instead bring it to their attention as evidence that one of their systems (or personnel) may have been compromised. ___ gnhlug-discuss mailing list gnhlug-discuss@mail.gnhlug.org http://mail.gnhlug.org/mailman/listinfo/gnhlug-discuss/

I do have a Facebook account and may or may not have allowed a "session" to remain active overnight, though I'll claim that shouldn't matter as I ask the following: is there *ANY* legitimate reason why anything should be attempting to connect from Facebook to my home IP address, which offers no such services?

Ah. I'll probably concede any point you want to make about the dictionary definition of "-proof" as a modifier not meaning "perfect", but definitions and proper usage often seem to matter less than we'd like. (And, yes - I *could* care less! >-/ ) The security-is-a-process-not-a-product dictum reminds us of our burden; the "process" of security costs vigilance and resources. So, given any problem P, calling a thing "P-proof" makes it tempting to tick the SOLVED box and move on; vigilance wanes or vanishes, dictionaries remain safely undisturbed on the shelf. News-beings reporting on high profile penetrations or malware infestations these days don't even bother to mention a specific OS or vendor; the generic term "computer" is sufficient and, statistically, it's likely that the reporter and most of the audience all conjure the same image when that term is used. It's to the point where the only reason it's newsworthy to mention the OS in question is when it's *not* Windows or Mac. Since it's likely (inevitable?) that compromised Linux systems will someday be involved in sensational headlines, I'd think it would be even more humiliating if somebody can dig up claims that Linux is "virus-proof" or "immune" or "uncrackable" or... FWIW, some term that conveys the "process" idea, or the notion that "perfect-security-is-impossible-but-we're-better-than-most" would be preferable.

Me, too, though communicating results from the interactive process back to the parent process (the one desiring User input) may only be part of the puzzle. If we hope to provide a flexible solution we should allow for the possibility that no TTY style interaction may be possible. Does the parent have its std{in,out,err} connected to something suitable for interactive use, or indeed to anything? Maybe it's a daemon or something launched from cron. An X-based solution could still work in such circumstances; it might even be preferable in some ways as it would likely leave std{in,out,err} free for communications with the parent. ___ gnhlug-discuss mailing list gnhlug-discuss@mail.gnhlug.org http://mail.gnhlug.org/mailman/listinfo/gnhlug-discuss/

Re: Am I 32-bit, or 64-bit?
It'd take some pretty bizarre build errors to generate a kernel that describes itself as x86_64 when it isn't. Therefore, (assuming you're really running in the filesystem that your x86 system was based on) what's likely happening is that the exec() machinery that allows mixed use of x86 and x86_64 binaries is doing its thing and it wasn't until the Chrome installer asked the kernel which flavor it is and then started looking for the (absent) x86_64 loader and libraries that you even noticed. BTW, for recent kernel sources I think the value you wanted to use for ARCH is i686 rather than i386, even though the latter may be what the "arch" command reports. ___ gnhlug-discuss mailing list gnhlug-discuss@mail.gnhlug.org http://mail.gnhlug.org/mailman/listinfo/gnhlug-discuss/

It's certainly possible to write a filesystem onto (say) /dev/sdc (the whole disk rather than a partition thereof) and then mount /dev/sdc somewhere; in my experience everything Just Works. That violates the Principle Of Least Astonishment these days, though, so use partitions unless you have a clear need to do otherwise. And, certainly, in the OP's case where his dd'd image was pulled from a partitioned device, an fsck run against that entire image (instead of one of its partitions) is guaranteed to fail. > In order to access partitions within an image file, you want > the "kpartx" utility: > > http://linux.die.net/man/8/kpartx A very handy tool. Before kpartx I'd compute offsets of partitions by hand when rummaging around inside partitioned images, using loop devices to access them.

Re: Testing direct IO with FIO
Does your strace output show any fcntl() calls? I believe it's possible (maybe even necessary?) to set attributes like O_DIRECT and O_ASYNC using fcntl() as well as during the original open(). ___ gnhlug-discuss mailing list gnhlug-discuss@mail.gnhlug.org http://mail.gnhlug.org/mailman/listinfo/gnhlug-discuss/
WANTED: rebuildable/salvageable computers/components
I've been assembling computer systems from donated/scavenged components, installing Linux and then giving them away on Freecycle to folks who are glad to receive them, no matter how humble the machine. I naturally prefer to obtain otherwise functional systems whose only affliction is the presence of Microsoft products on the disk (easily cured) but I've also created some Frankenstein monsters with components from several other carcasses. So, if you're tossing a machine (or usable components thereof) please consider sending me a description and I might be able to put all or part of it back into service instead of it ending up wasted in a landfill. ___ gnhlug-discuss mailing list gnhlug-discuss@mail.gnhlug.org http://mail.gnhlug.org/mailman/listinfo/gnhlug-discuss/

Re: home design + construction + landscape design software? (CAD, remodelling)
I'd forgotten that I, too, have a friend (in an NYC architectural firm) who recommends Google's Sketchup. I've not used it. I daydream about being able to walk around the house snapping photos and feeding them to some app where I click on key points while specifying dimensions and such, from which the app then deduces the entire layout and generates a manipulable wire-frame, 3d renderings, a materials list, etc, etc. [ IIRC, I may have seen a gizmo on This Old House that will scan a room with a laser and do many of the things in my wish list, but it's probably expensive and almost certainly not Linux-related. ] ___ gnhlug-discuss mailing list gnhlug-discuss@mail.gnhlug.org http://mail.gnhlug.org/mailman/listinfo/gnhlug-discuss/
Re: home design + construction + landscape design software?
Yeah, to really be useful a program like the one you (many of us!) are looking for ends up being a serious CAD system and, unsurprisingly, nobody's giving those away. I've used that sweethome3d and it's nice for fooling around with general layouts (even that took me a fair bit of noodling) but back when I tried it (approx 2 yrs ago) I concluded it was unsuitable for planning an actual remodelling project. I still have some of the images I rendered: http://b0rken.com/20091214kitchen/ ___ gnhlug-discuss mailing list gnhlug-discuss@mail.gnhlug.org http://mail.gnhlug.org/mailman/listinfo/gnhlug-discuss/

Re: SCP from STDIN: "-t" option undocumented?
Having just now quickly RTFSC and done a few superficial experiments I conclude that the -t option (mnemonic for "to"; there's also a secret "from" flag -f) is not suitable for use by humans. It tells scp that it's in "server" mode and should expect to communicate with its counterpart using some undocumented protocol that appears to mix commands and data in-band via stdin.

[semi-OT] SPAM email headers don't mention my email address?
I'm getting much less SPAM in the last year or so (yay!) and I gather that's at least partly due to the shutdown of some botnets. And I hate to say anything positive about ComCast but I think another factor is that their filters are pretty good. SPAM volume is now low enough that it's remarkable when one gets through, so when one arrived this morning I had a look at the headers and it reminded me of a question I've had for some time: How does a message like this get delivered to me even though the headers (at least those present in the message as delivered) never mention my email address? Last time I started to look into this (over a year ago) I think I got as far as concluding that the trick somehow involved the Blind-CC mechanism but then I got distracted by another matter and didn't pursue it.
