I once watched Def Con talk about security fails. Some idiot tried to hide a file and overwrote it somehow with "F**k you" over and over, or something similar
Overwriting a file over and over again on an SSD just wears your cells, but does not guarantee you're overwriting the cells you actually want to erase at all.
SSDs can only be erased completely (full-disk) at once by the disk controller.
Can anybody recommend a dual-band, half-height mini-pci WIFI board that is both fast and isn't prone to the coughing fits that Intel's iwlwifi driver seems to be? I've got a broadcom one that won't go any faster than ~72mbps a pile of Intel ones that are all completely rubbish in their own little ways and now Realtec on that is also locked at quite slow speeds.
Just looking for a known-good card that can manage ~300mbps without choking. Any clues?
@ThomasWard Just curious of your opinion on this : unix.stackexchange.com/a/337042/85039 (not just my answer, but the question itself in general). Is the user's "fear" substantial enough ?
I have been trying to install arch on my mid-2011 Macbook air, I moved the ISO to an 8GB USB-Drive with:
dd bs=4M if=/home/ronnie/Downloads/archlinux.iso of=/dev/sdb status=progress && sync
Then, I restart and get the rEFInd boot-loader and have four choices to boot from the liveUSB. The first...
Hey guys. I know this question is all over the internet. But really, should I learn python or c++ if I want to be a Linux developer (one day) and is bytes and bits a good site to learn python from?
@RonnieDroid You can make software that runs on Linux using pretty much any language (although I wouldn't recommend objective C or .NET). For some things, scripting languages like Perl or Python are better, for others compiled languages like C work best. There is no one, good answer to what you're asking.
If you don't know how to program at all, you might want to start with a high level scripting language (so Python, Perl, Ruby etc). Or, conversely, you might want to start with a low level one like C to learn the very basics. It all depends on how deep you want to go.
@terdon okay. Thank you for the help. I know nothing until now. So I think I'll go with Python just because it is much easier (that's what I read) then if I learn one, I think I'll be able to learn more
Most higher education CS places tend to start you with a high level language and let you build something, then teaching you about C to ruin your life, then teach you about assembly to make you really value C and then let you do whatever you like... By which point you end up back in a higher level language but appreciate what they're doing.
I don't think I'd ever advocate learning something as complicated as C++ as a first language. I'm sure it's possible but I've worked with people who started with C and C++ and it makes for some really cranky programmers.
C is a bit better because it's hard to do enough to get opinionated about. 99% of your first week with C is spent swearing at, crying on and pleading with the compiler.
@Oli well I already ruined my life writing my first novel (which still needs editing but I'll take a break from it for now) so I need to learn with fun, no ruining-lives languages please. Haha
@Oli thank you for the information. So as I want to learn to make software for Linux, I think python well cover that, and I have no plans to do anything more than that for now.
I read the tour page, and it said accepted answers aren't always the best, they just mean that it worked for that user. Well, it is possible to have two working answers, so why can we only have one accepted answer?
@UbuntuUser I deleted one of your three answers since that was just an request for more info from the OP. In general, while it's OK to post multiple answers if they each offer a different approach, it is usually better to post a single answer with both approaches.
I updated my Ubuntu 16.04 and now I have this issue.
The file names and some texts are missing. I had this issue earlier but it didn't exist after rebooting the system. I don't want this problem again, do tell me what I can do :)
@terdon @UbuntuUser : I just saw this question -> askubuntu.com/questions/871423/dd-command-unrecognized-operand which includes a link to another question -> askubuntu.com/questions/710535/… for which I provided a working answer a long time ago. Today I received two downvotes ... Haven't you seen that the machine in the old question had a Legacy BIOS ? I am asking because of your comments on the new question. I updated the old posts.
@terdon @UbuntuUser I updated the old posts by highlighting this information to make it better visible ... in case you downvoted my correct (I tested them of course before posting) and working (accepted) answer, please revoke those downvotes ! Thanks in advance ! :)
@terdon It copies the first sector of the ubuntu partition to the Windows partition ... I always did this in times when I dual booted ubuntu and Windows Vista using the Windows boot loader on an old Legacy BIOS machine !
@terdon bcdedit /set {***} path \linux.bin ... this tells the Windows boot loader where to boot from ... again : please believe me, that did always work ... this is the problem with old answers and users not reading things carefully ! :)
@terdon Did I ever say I am perfect ? I wanted to make the answer as short as possible ... in that old time I copied the first sector to an USB and from there into Windows ... later I tried it directly ... and saw that it worked ... used it over and over again ... :)
@terdon As you can see, I care a lot about the quality of my posts ... so without talking to you I might have overseen that space forever ... please bare in mind that I wrote the answer more than one year ago. :)
And that's perfectly understandable. All I'm saying is that you came on a little strong there. A simple "hey, is anything wrong with my answer?" would have been much better than addressing specific users (neither of whom had anything to do with your downvotes, AFAIK) and accusing users of "not reading carefully". That's all.
asking people to revoke downvotes (even if you qualified it with "in case") is a risky thing. you can't prove who downvoted you, so it is your words vs. their words and that isn't a productive exercise at all.
@cl-netbox No need to apologize, I know you get passionate about your answers :)
And yes, of course the right dd command (as shown in that post) would work. The error the other OP was getting was because of the space.
And a good thing too since your command would have wiped the beginning of their drive. That's 100% for the question you answered, but not very good for what the OP wanted to do.
hey guys, i wanna ask something, i was thinking of using something light weight on my laptop, but has good looks nonetheless, also i have a very specific need, something that is more towards web based usage. i like peppermint os. but is there something a little older, with a stable history, just asking !!!!!!!
i know, kde plasma 5 is real eye candy, but in my usage it went up to about 1.3 gigs of ram usage in a basic install with my required softwares on boot
8, but running around 15 - 20 tabs in chromium and matlab and weka in the back, leaves barely 100 mbs at times while i work , i am university student, i need to run algorithms on datasets
I am waiting for a stable release of 17.04, and i cant really afford to have my system crashing on me, my supervisor will kill me
so not using the testing releases of ubuntu 17.04 or debian
as i said, i really loved peppermint os, but it crashed bith in my actual laptop and the vms i made with different setups
i would have loved to get arch, but cant really afford giving days to just setting up, and keep fixing issues of software compatibilty ( trust me arch takes time ) !!!!!
@Hizqeel well, if you feel it is actually trying to answer, then no, don't flag. If it's bad, just downvote. The NAA flag should basically be used for things that are, well, not answers. Say, if I ask "How can I list all files in a directory?" and someone answers "With cucumbers!", that should be flagged.

A guy spends some time writing an answer which he believes is right. But then reads it again and realizes it's wrong. So he grabs gdb, opens like 5 tabs on gedit and disassembly a program, writing what EVERY assembly instruction (maybe 2 or 3 I didn't know the purpose) did, mapped the whole stack, examined the memory on the stack
after hours of work, he realizes his answer was actually right, he just quoted the wrong part of the man page of gcc
