4:01 PM
@FaheemMitha Yeah that's good advice. I try to remember that it could always be worse and that as long as you "keep your chin up" and keep pushing forward it will almost certainly get better. Sort of the further you fall the easier it is to get back up
 
@FaheemMitha I think most ISPs still offer it, may or may not be outsourced to Google. Only hosted email I've used recently is at work, where we've outsourced it to Google.
 
Outsourced to Google? Ugh.
 
Can't escape it! lol
 
I got the impression that Luxsci uses sendmail. Which is weird.
 
@Jesse_b BTW, I'm pretty sure when presented with a valid order to turn over email, every US-based email provider will do so. Not just Google. And presumably the same for non-US ones, when presented with the right paperwork for their jurisdiction. That's the law...
 
4:04 PM
@derobert Oh for sure. Google had an event though where the government asked them for the email of a single person and they turned over full backups of EVERYONE's email
 
@derobert The point is some of these companies don't require a valid order.
Which is nice for the US govt, because often they would have a hard time getting one.
 
It was discussed in a defcon conference, maybe like 2014? The legality of it was in question because the US has strict laws against the government looking at your USPS mail or listening to phone calls without a valid warrant, but it was determined that email providers can do it because your email is stored on their hardware and therefore they own it not you
 
Wasn't part of the Snowden revelations that some of these big companies had built-in backdoors?
 
@FaheemMitha Hah, the US government used to maintain it just required a subpoena. I'm not sure if they still do... But the idea that a prosecutor couldn't get a subpoena is absurd. Only reason I can think of is the office photocopier broke.
 
@FaheemMitha I don't think that's even a secret thing. It's well known that sprint has a portal designed for law enforcement that they can log into and read texts from any sprint customer without a warrant
Tmobile moved away from natting phones for the sole purpose of making it easier to track them for government officials
 
4:06 PM
@derobert Well, I do know in practice often they don't get warrants. Otherwise why have secret backdoors? So maybe it's not so easy.
Is it possible to get warrants or whatever with no reason? Because I suspect that's often the case with the psychos in the US Govt who spy on people.
@Jesse_b natting?
 
@FaheemMitha Possibly they gave up on that crazy interpretation of the law. Or of course, it makes the case much stronger — reasonable chance a court suppresses the evidence saying it required a warrant. But if you can get the warrant, then that won't happen.
 
@FaheemMitha My cousin is a detective in new mexico and he claims it's actually much harder than people think most times
@FaheemMitha network address translation. I guess NATing would be more appropriate
 
@Jesse_b Ok. I'm not immediately seeing how that is relevant.
@derobert Unusually, I'm not following you here.
 
@FaheemMitha Also... there is no warrant (or anything) requirement to spy on foreigners.
 
@derobert Yes, well. That's a separate issue.
 
4:09 PM
@FaheemMitha I guess since the phones all got NAT addresses they weren't able to pinpoint a specific user (since they didn't know what IP that user was using)
 
@Jesse_b Oh. Right.
 
We get people posting to the OpenBSD-misc mailing list from ProtonMail accounts from time to time, but for some reason they are almost always trolls.
 
@Kusalananda I'm not sure what to infer from that.
 
Oh yeah
 
@FaheemMitha Say that a prosecutor seeks to introduce subpoenaed emails into evidence. The defense could challenge that was obtained illegally, a warrant was required. If the defense won, the evidence would be suppressed. So a prosecutor can always go above the law's requirement; if the prosecutor got those emails via warrant, the evidence would be safe. Can't challenge it for "you got a warrant but only needed a subpoena". So a prosecutor might do so even when not required.
 
4:11 PM
@FaheemMitha Sorry, I should have connected that to the discussion a bit further up where ProtonMail was mentioned.
 
@Kusalananda I suspect many OpenBSD-misc subscribers would be wary of using web-browser-based OpenPGP encryption
 
come to think of it, almost everyone that signs up for a fraudulent account with my companies cloud is using a protonmail account
 
But I'm not sure what's generally considered required, and if the 180-day period from the SCA matters anymore.
A warrant requires a magistrate to sign off on; a subpoena does not. So a warrant is a bit harder to get. (The evidence required is also different).
 
@derobert Ok. I see. Sure, it's better for the prosecution to get a warrant. But only if they are actually using it to have a trial. As you know, lovely people like Obama etc. don't do things that way.
They prefer dropping dropping bombs on people remotely via unmanned aircraft. Or locking them up without due process.
 
Except for the drone strikes, Obama mostly did trials.
 
4:14 PM
I imagine Trump has similar preferences, though for some reason we don't hear much about that.
@derobert He did? I thought he liked the Cuban jail.
Or the concept of it, anyway.
 
@FaheemMitha his trials are BIGGER, so MUCH BIGGER
 
I mean, even the existence of that Cuban base is illegal.
 
the BEST TRIALS EVER
 
It was obtained from Cuba at the point of a gun. In the 1930s, I believe.
@StephenKitt I can see you're a fan.
 
@FaheemMitha humanrightsfirst.org/sites/default/files/… ... so he inherited 242 from Bush, and got it down to 41.
 
4:16 PM
@derobert I see. I wonder what happened to the other people?
Annual cost to operate Guantánamo: Approximately $445 million.
Wow.
 
@FaheemMitha A lot of them were released
 
Transferred, repatriated, or resettled was 197
 
@Jesse_b Really?
 
@FaheemMitha Yeah...I mean we traded like 7 of them for that treasonous bergdahl character
 
I'm not sure exactly who that organization is, but they have a NY Times cite for where the people went... nytimes.com/interactive/projects/guantanamo/timeline
 
4:17 PM
@Jesse_b Oh. I don't know who that is.
 
@FaheemMitha He was an army soldier that deserted while in country and gave secrets to the enemy. Then returned home with a heroes welcome and retirement pay
 
@Jesse_b I see.
 
It was worth setting a precedent of negotiating with terrorists to save him
 
Also note the last arrival of March 14, 2008. So you really can't blame Obama for gitmo. That was a G. W. Bush policy. (And remember also Obama wanted to close it — but Congress prohibited him from doing so.)
 
Beaudry Robert "Bowe" Bergdahl (born March 28, 1986) is a United States Army soldier who was held captive from June 2009 to May 2014 by the Taliban-aligned Haqqani network in Afghanistan and Pakistan after he deserted.Bergdahl was captured after deserting his post on June 30, 2009. The circumstances under which Bergdahl went missing and how he was captured by the Taliban have since become subjects of intense media scrutiny. He was released on May 31, 2014, as part of a prisoner exchange for five Taliban members who were being held at the detention center at Guantanamo Bay. This exchange and the...
I don't see the hero's welcome.
 
4:20 PM
He was returned home as a prisoner of war not as a deserter
 
@derobert My understanding is that he wanted to set up a similar facility inside the US.
Which would have been directly in contravention of US law.
The Cuban prison wasn't illegal, because it was outside the US.
 
He did face a military trial but was ultimately found innocent and given several promotions. It would have looked really bad if we traded several high ranking terrorists for him and then convicted him of desertion when he got back
 
@Jesse_b Well, ok. Still not particularly heroic.
 
When he first got back he did a press conference with Obama (Heroes welcome)
 
@Jesse_b How do you know they were terrorists? That word gets thrown around an awful lot.
@Jesse_b Ok.
 
4:23 PM
@FaheemMitha Well they were enemy combatants. Whether they are justified or not is debatable. If I was born in afghanistan I would certainly be an enemy of the US
 
@Jesse_b Well, because the US invaded Afghanistan illegally.
 
@FaheemMitha I think he wanted to set up a normal prison inside the US (or possibly use out existing federal prison system). So it'd be subject to normal US law, not outside it.
 
@derobert Possibly. I don't have any documentation about that. Just what I recall reading. Which I might have misunderstood. Or the writer could have been wrong.
I think Glenn Greenwald wrote some stuff about it.
 
@Jesse_b wait, what? That's not what that Wikipedia article says.
 
@derobert Which part?
 
4:28 PM
@Jesse_b under "Military investigation and court-martial" it talks about pleading guilty to desertion: "On October 16, 2017, Bergdahl, via his attorney, pleaded guilty to charges of desertion and misbehavior before the enemy."
"On November 3, 2017, military judge Nance accepted Bergdahl's guilty plea and sentenced him to be dishonorably discharged, reduced in rank, and fined $1,000 per month from his pay for ten months, with no prison time."
 
Huh, I guess I remember it incorrectly
I know when he first came back he was promoted to sergeant though which pissed a lot of people off
 
@derobert So you have no email hosting recommendations?
@Jesse_b Or you?
 
@FaheemMitha I don't, I use gmail lol
 
@Jesse_b That's sad.
 
I think the fact that spammers and scammers use protonmail is actually probably a good thing though. They likely take customer privacy seriously
 
4:39 PM
@Jesse_b LOL
 
@FaheemMitha honestly, I'd probably tell someone who isn't going to run their own server to use gmail, unless they have some weird requirements.
 
@derobert Eek. Weird requirement, like not being spied on?
 
And sure, the US government might spy on you. The same is true of almost every provider. But Google at least has fully TLS-enabled their mail service, unlike a lot of smaller providers.
@FaheemMitha Unfortunately, that is a weird requirement.
 
@derobert It's not just the US govt. Google itself goes through stuff. And maybe their friends.
@derobert I don't think that's weird.
How is Gmail spam filtering?
 
@FaheemMitha It's pretty good
 
4:44 PM
@Jesse_b ok
 
Google is by far the largest email provider. Paid email is tiny in comparison. So being spied on is the norm. (And yes, then everyone complains about it on Facebook...)
 
I think many mail providers do it now but gmail also has a cool feature where you can do like jesse+something@gmail.com to sign up for things
So if you start getting spam from that company you can easily filter all those emails aout
out*
 
@derobert I don't use Facebook. And that's ironical. Seeing as what FB does.
@Jesse_b Other people do that.
 
@FaheemMitha Yep, exactly. I don't use FB either. But it's hugely popular, and entirely makes its money examining what you do on the site to sell ads.
Of all the reasons to spy on someone... I confess I don't get that worked up with "to target ads".
 
I need some éminence grise to tell me if I need to delete / edit my own answer:

Q: Is an answer including commercial software on topic on U&L?

FabbyOn my main site, (AU) answers including commercial software are on-topic as long as it's relevant and you're not the owner or you disclose you're the owner and you don't use the platform to SPAM. As I just posted an answer referring someone to commercial software (although with a money-back guar...

@StephenKitt: track0 contains the MBR and/or partition table.
 
4:54 PM
@Fabby right, but why would that prevent recovery using ddrescue?
 
(do you want me to add that below the comment you just left?) I'd rather take this up here as it might confuse the OP
 
@Fabby here is fine
 
not for photorec and for testdisk, but for anything else out there: it's just an unreadable image you cannot just mount.
 
@derobert People can find other reasons.
 
(or is that a non sequitur?)
 
4:56 PM
@Fabby but the OP mentioned trying PhotoRec and TestDisk without success
 
The point is that the information is out there for people to use.
 
@StephenKitt yeah, because they can't figure out neither what the disk's actual contents are neither!
 
If Google gets taken over by not-nice people, who knows what might happen?
 
(parted shows -512 GB, disks shows 18 Exabytes, ...
 
@Fabby well yes but that wouldn’t stop PhotoRec from doing something if anything was readable at all ;-)
 
4:57 PM
It's a bloody mess!
 
Assuming, of course, that the current owners are "nice".
 
indeed
 
@StephenKitt That's why IMHO he needs hardware recovery: the disk is not recognised
 
basically what bothers me about your answer is that it suggests sector 0 has magical properties (to naïve readers)
 
And I've known SpinRite to recover stuff like that.
 
4:58 PM
(since you mention not being able to recover disks with a bad sector 0)
(and seem to suggest that a bad sector 0 would explain the symptoms, which I don’t think it would)
 
@StephenKitt :D OK. Not I get where you're coming from.
In my experience, such a disk cannot be recovered except maybe by SpinRite or Hardware recovery.
How should I phrase that?
Actually, I'll remove the reference to track 0 as not to confuse anyone.
 
@Fabby that seems fine to me ;-)
 
@StephenKitt Thanks fropm bringing it up!
No imps, mages nor any black magic needed!
 
@Fabby you’re welcome! I suspected you knew what you were talking about, but there’s enough obscurantism out there around hard drives and I’d rather avoid spreading it ;-).
 
@StephenKitt :D :D :D
I'm from the CP/M era where booting your machine meant:
Read track0/1
 
5:03 PM
@Fabby yup
 
Edited again and removed second appearance of track 0
@derobert thanks and no, it's an 8-Bit DOS program that comes in a bootable image bundled with FreeDOS...
@derobert Ah, I see what you mean now! Yeah, it's a self-extracting EXE file/
 
@Fabby 16-bit, it’s not CP/M ;-)
 
@Fabby self-extracting exe file? Is there a way for someone running e.g., Linux to make the boot disc for it? If there is, and it's not entirely obvious, that'd be good to explain.
Of course, I guess in principal, "go find a Windows machine and do X" can be an answer too.
 
@derobert You can iopen the EXE in fileroller or unzip it or request an ISO file from the manufacturer
@derobert It's an iso wrapped in a home-grown self-extractor written in Assembly.
the first screenshot is indeed a Windows executable
all the rest is pure DOS INT13
 
@Fabby that sounds worth mentioning in the answer.
 
5:12 PM
Added another note in the answer to mention he's on Linux and they'l deliver just an ISO.
@derobert Well, I don't want to be singing Hail Mary's about this piece of software neither.
Otherwise the footnote about this old, ugly but very efficient piece of software is going to be longer than the
 
Fair enough. It looks like you've updated your answer to include the relevant info for how it applies to a Unix user.
 
(looking for word)
@derobert Yup.
What's the English word for "examination" but for a problem and not for a human?
ah! Root-cause analysis will do!
so, don't want to write too much about Spinrite as the note would be longer than the root cause analysis!
@derobert :P ;-)
 
I wouldn't call that a root-cause analysis. I've had some Seagate disks fail like that, though. They were part of RAID arrays, so never bothered attempting recovery...
 
How do I know if SpinRite 6.0 will work for me?
What drives does SpinRite run on? What does it need?
SpinRite can run on any PC compatible system with a 32 or 64-bit Intel or AMD processor and a color screen. The previous SpinRite v5.0 is available to v6.0 owners who need to run SpinRite on older 16-bit 8086/80286 systems and/or monochrome screens.
@derobert It's not what I want to say, but that comes closest. Lemme go for a smoke and think about the word...
(English is only my third or fourth language, depending on how you count)
 
I'd also try taking an external drive out of the external enclosure and connecting to a SATA port.
 
5:18 PM
Damn I'm an idiot!! Analysis is the word I was looking for!
(getting up to go for a smoke fired the right neuron!)
@derobert Mmmh...
True!
Lemme add that!
SMOKE FIRST!
 
5:31 PM
@StephenKitt care to remove your comment?
 
@Fabby I removed it quite a while ago
 
@StephenKitt ah, caching then...
 
+1 :-)
 
It seems to me the relevant demarcation is free vs proprietary software. Not commercial vs noncommercial. Since any software is potentially commercial. I could put up an ad to sell copies of the GNU Emacs program for USD 1000 per license, and it would be perfectly legal, though only a lunatic would buy it. — Faheem Mitha 19 secs ago
(Minor corrections made...)
 
@FaheemMitha :D
Thanks for the laugh! I needed that after the first downvote!
 
5:40 PM
@Fabby hah, looks like your rewrite got you two extra upvotes though, so I hope you can live with that downvote :-P
 
@Fabby What downvote?
 
@derobert Yeah, I can!
@FaheemMitha This downvote
 
@Fabby Oh. You're too sensitive.
 
@FaheemMitha Yes I am: I try to do things too well and hold myself to a very high standard.
I need to split for an hour or so for Real life stuff
 
@Fabby You should try to relax.
 
5:44 PM
(like food)
@FaheemMitha I'm going to right now!
:D
 
Blatant homework
-2
Q: how to write a makefile to run these codes?

Khang NguyenThe code in project2 is for a program that plays a simple game called Chomp. The programmers of this project have opted to package some of their code in a “module” called chomp.adt, from which the related files cookie.h and cookie.cpp files can be generated. The steps necessary to produce this ...

> Note: you will probably not be able to base this makefile upon my self-updating makefile as in the earlier part of the assignment. Instead, you will probably find it necessary to write this one from scratch.
 
@StephenKitt Time to offer some private tutoring, perhaps.
 
@Fabby ha ha yes please
 
@Fabby Wow, Chromium sucks at rendering that.
Chromium on the left, Firefox on the right.
 
5:58 PM
@derobert wow! Apparently I used a shadow in the font...
 
I wonder if gif support is just broken in Chromium — and if it's just me, or everyone.
 
@StephenKitt sounds like give me teh codez and Homework
@derobert Chrome rendered it poorly here; Firefox & etc all OK
 
@JeffSchaller yup, I wonder if we should add tags ;-)
 
@StephenKitt then you'd be calling for trogdor to eat your homework
 
oh that’s addressed in the homework question
 
6:06 PM
:(
 
PNG this time and no shadow on the font. @StephenKitt@JeffSchaller@derobert
 
@Fabby looks good!
 
:-)
 
6:22 PM
Hmmm, I wonder if "I will not ask Unix & Linux to do my homework for me" would be better...
 
@StephenKitt I thought the word was tidbit but my spell checker wants to correct it to titbit (which contains tit, which is totally allowed in the UK, but a dirty word in the US, so asking you which is correct so I don't get into trouble)
 
6:42 PM
@derobert Urgh...
OK, Re-doing it
0
Q: I will not ask homework questions on Unix & Linux

FabbyAs per chat here is a little tidbit that I made that can be put below obvious homework questions where the author is not asking about specific help at where they're stuck but rather want a Gimme the codez... Version 1 If this would not be welcoming enough according to the CoC, please let me k...

Your wish is my command, master!
:D ;-)
 
7:31 PM
@Fabby I wish people would stop posting Simpson cartoons.
Really not a fan of the yellow people.
 
@FaheemMitha Sorry for offending you: it's just a cartoon...
 
@Fabby Not offended.
I'm just not a Simpson's fan.
 
grep -rnw . -e SENDMAIL=True to search for pattern SENDMAIL=True in current directory recursively
Does this syntax hold good?
 
It seems to have been around forever, too.
 
@overexchange Works for me but I would use quotes grep -rnw . -e 'SENDMAIL=True'
I don't think it's really needed though but there may be some case where that = is interpreted in an undesired way
 
7:43 PM
ok
 
@Fabby That's not really a question, though. Unfortunately on a QA site, if all you have is a hammer, everything looks like a nail, I suppose.
 
@Tim I don't think so, but why?
 
@FaheemMitha On AU Meta is used for announcements as well...
 
@MichaelHomer That's not exactly a well-defined term.
 
7:52 PM
@overexchange if I had my druthers, all of the options would be before the parameters: grep -rnw -e SENDMAIL=True . even though GNU tools can parse it, just to make it easier on the human to tell what's going on.
 
@FaheemMitha Indeed.
I pay Microsoft to run my email, but I suspect that's not a popular option here.
Running a mail server is hard.
 
@MichaelHomer Microsoft? What service is that?
@MichaelHomer And could be depressing. All that Spam.
 
@MichaelHomer Running Installing a mail server is easy... Protecting it well and doing good spam filtering is hard... ;-)
 
@MichaelHomer Thank you. I didn't know about that. Odd choice for a Linux user. How is the service?
 
7:58 PM
@FaheemMitha I have never had any problems with it.
 
@Fabby I think the spam part is implicit in the "running" part. Imagine a world with no spam. That's how it was in the early days of the net. But you've been around long enough to remember that.
@MichaelHomer Ah. What's the monthly cost? And how is the spam filtering?
The page you linked to says USD 4 at the top.
 
@FaheemMitha Yes, I remember BBSes, FidoNet, Compuserve, ...
 
@Fabby I don't really remember those, but I remember a (relatively) spam-free internet.
 
The spam filtering is fine, sometimes it filters things out I want to keep, but it gets better. I assume it's also $4, but I pay annually and in a different currency.
 
@MichaelHomer Gets better how? Is it trainable?
 
8:00 PM
@MichaelHomer lemme guess: Crowns?
 
@FaheemMitha I tell it the message wasn't spam
 
@MichaelHomer I see. So that helps the filter? I suppose it's a Bayesian thing.
 
@Fabby No?
Well I suppose it does, later messages tend to end up delivered
 
@MichaelHomer I wonder how you wound up using that. Not exactly an obvious choice.
 
@FaheemMitha There aren't many providers at suitable scale to pull it off. ActiveSync is sometimes handy too.
 
8:07 PM
@MichaelHomer What suitable scale?
I thought this was for your private email.
 
9:00 PM
Basically them and Google. You need a lot of infrastructure to do a good or even adequate job on email and to secure it
I have run my own servers before and it was a nightmare, and I've run them for work before and it was a nightmare. I do miss procmail though.
 
9:27 PM
Is there a way to view the source of my PS1, before it has done the replacement?
 
@AaronHall Just print it out?
For bash/zsh printf '%q\n' "$PS1" will give you a fully-escaped version.
 
or echo "${PS1@Q}" which I think is bash v4 or above
 
what's %q do?
 
quote
@Q I think is 4.4+
For bash
 
>ARGUMENT is printed in a format that can be reused as shell input, escaping non-printable characters with the proposed POSIX $'' syntax.
(printf %q)
 
9:44 PM
@MichaelHomer it didn't work on the version I have on RHEL..., but the printf one is fine.
 
10:01 PM
@FaheemMitha you could always palette-swap it, making everyone wonder...
 
Yellow lives matter
 
@derobert Not sure what you mean.
 
@FaheemMitha Then you could have green people. Or purple. Or whatever.
Just not octarine. Please none of that.
(It wouldn't work for the purpose, since the people who need to see it couldn't.)
 
@derobert Still not following. It's possible my brain is fried. Why would I want vari-colored people?
@derobert You mean The Color of Magic?
Yes, apparently I remembered that correctly.
 
@FaheemMitha Because you're really not a fan of the yellow people. You could make them green.
 
10:15 PM
@derobert How about normal colored, vaguely pink or brownish people?
 
@FaheemMitha his head is a cylinder with a sawtooth on top and eyeballs as large as his hands. I don't think normal is possible to achieve by color change alone.
 
@derobert I forgot you were a Pratchett fan. Though I seem to remember us swapping quotations at some point. Possibly on the sad occasion of Pterry's demise.
@derobert Who is he?
 
@FaheemMitha Bart Simpson...
 
Name element 117 Octarine? If you think that's a good idea - and we do - please sign the petition here; https://www.change.org/p/iupac-joint-institute-for-nuclear-research-lawrence-livermore-national-laboratory-name-new-element-117-octarine-in-honour-of-terry-pratchett-s-discworld
@derobert Oh, him. Ugh.
Alas, a new element didn't get called Octarine.
 
@derobert "His head is a cylinder with a sawtooth on top"
Loled pretty hard at that

Hi
Has anyone of you installed Ubuntu on a hard drive with USB adapter? How has your experience been? I want to do something like that but I'm worried that in the shutdown or for some reason the file system gets corrupted.
