TrueCrypt Master Key Extraction and Volume Identification

mrt_2394871 Re:What about a face recognition trick? (222 comments)

Face recognition (at least the Android Jelly Bean/Kit-Kat version) gives too many false positives at the moment. Somewhere between 5% and 20% of the time, my face does not unlock my phone/tablet, and I need to enter a PIN.

Also, the scope for involuntary unlocking is much larger.

Google Makes It Harder For Marketers To Collect User Data

mrt_2394871 Re:And google will retain that info exclusively. (195 comments)

If you want to know if I've read an email:
request a return receipt
If I want to give you that information, I will.

Goodness, there's an existing, non-scummy way of working all this out which preserves user expectations of privacy and provides you with the information you actually want, not a poor proxy of it.

What Are the Genuinely Useful Ideas In Programming?

mrt_2394871 Re:I can think of one that Steve Jobs disagreed wi (598 comments)

"Quicksort is already implemented a thousand times, so there's no need to implement it again, just find which library you need."

Yes, that's true, but we're talking about education here, not building websites.

Also, knowing about QS implementations lets you know when it's been done wrong.

Case in point: Microsoft's C runtime library shipped around the time of Windows NT and Visual Studio 6 had a sub-optimal qsort implementation - it took 97 seconds (on a 600MHz Athlon) to sort 260,000 integers with a constrained set of values (0-180), whereas other implementations (eg Numerical Recipes) could do it three orders of magnitude quicker.
Delving in, the qsort() algorithm didn't exchange elements where the value equalled the partitioning element, which leads to increased comparison function calls (effectively proportional to 1/range).

Ask Slashdot: Suitable Phone For a 4-Year Old?

mrt_2394871 Re:4 years (682 comments)

Actually, I gave my 3yo daughter an older smartphone with no SIM. [...]

Most phones, even if you remove the SIM, will allow you to phone the emergency services (999, 911, 112 or whatever). I believe it's a requirement of the GSM standard.

Romanian Science Journal Punked By Serbian Academics

mrt_2394871 Error! Reference source not found. (95 comments)

Is this real? (Metallurgia International's web site appears to be gone, so there's no direct proof).

Surely even the worst kind of journal would ask that the Error! Reference source not found broken cross-references be fixed?

"Ballooning" Spiders Use Electrostatic Forces To Generate Lift

mrt_2394871 Re:Nature is amazing (213 comments)

What if the intelligent designer just wanted to use evolution? I've never understood why the two solutions have to be exclusive.

Well, Intelligent she might be (gives you the afternoon off, after all), but it's a bit more dispassionate than I'd want my Benevolent Omniscient Being to be. Have you read about all those parasites? The ones that eat their host from the inside out, the ones that affect the brain, so the host goes wandering out into wide open places and gets eaten, etc.

It's almost Lovecraftian.

Disney's Titling Problem With Its Star Wars Movies

Google Enables VP9 Video Codec In Chromium

mrt_2394871 Re:It's... OK. (161 comments)

... why bother? ...

If VP9 wasn't there, H265 would face no competition. So then the H265 consortium would be able to pull all sorts of egregious crap. End-user licence fees, mandatory unskippable ads, you name it, they could require it.

But VP9 does exist. So they very probably won't.

Did Google Tip Off EU About Microsoft Browser Ballot?

mrt_2394871 Re:Snitch? (187 comments)

And if you search for "web browsers" on Bing IE doesn't show up at all except in a side bar under 'related searches'. Seems MS hasn't done any SEO for IE under the term 'web browser'.

But if you're using IE, you're using IE, and there's no need to search for it.

And if you're not using IE, then you're either on a platform which IE doesn't run on, or you (or your friendly BofH) have already taken steps to not be running IE. For either of those cases, you wouldn't be helped by searches for "web browser" listing IE highly.

So any outlay of resource on SEO would be wasted.

Google Docs Vs. Microsoft Word: an Even Matchup?

mrt_2394871 Re:A Mature Local Machine Product vs Immature Clou (346 comments)

Aren't those documents created or edited by LibreOffice by any chance?

Because in a few cases this has happened to me (with OpenOffice of course) but I don't remember a case that a document I created using word could not be opened with word. I edit very large documents (several hundred pages most of the time).

In my case, it was a Word document created in Word, saved (repeatedly) in Word which caused Word to crash (All the same version of Word). Fortunately LibreOffice could open it, and Word didn't crash on the resaved document.

Google Nixes Some Calendar Features and Other Software Offerings

mrt_2394871 Re:Carddav/caldav? (235 comments)

That's one of the biggest things that I've preferred iOS to Android. That, and the stupid way applications are stored on the system partition so you 'run out of free space' despite having gigabytes free.

That was changed with the release of ICS.

Not quite. ICS had almost seamless support for the "move to SD" model of app management, but it still got confused if you ejected any card (even one that didn't hold any apps).

My Nexus 7 (with JB) isn't partitioned at all.

Ask Slashdot: Current State of Linux Email Clients?

mrt_2394871 Re:thunderbird has the same problem as firefox... (464 comments)

Thunderbird with IMAP and the lightning extension installed routinely (like 20x per day) locks up for 5-10 seconds and shows wrong messages (or no message) when quickly switching between new emails.

Check if it's caching the calendar feeds. If it is, turn the caching off. That should solve the lock-ups.

Ask Slashdot: Which International Online Music Stores Are Legit?

mrt_2394871 Re:Magnatune (166 comments)

In addition to your points above, John Buckman is a cool dude. You can write a comment on his blog and get a reply.

I emailed him when Magnatune went subscription-only (I'd bought a dozen albums prior to that), with a bit of a moan that I could no longer buy per-album. I was astonished when I got a reply from him, setting out why he'd taken Magnatune down the route he had.

As you say, cool.

Microsoft Office 2013 Not Compatible With Windows XP, Vista

mrt_2394871 Re:theses (711 comments)

I wrote my thesis in Word (97, I think). There's a Master Document option so each chapter was its own individual file; equations used the default equation editor, and headings and table/figure numbering (and the tables of content, figures & tables) all used the standard Word facilities.
That said, all my figures were created elsewhere, and imported as EMFs (for vector graphics) or PNGs; and I used Endnote for the reference handling.
Since then, I've used Word's own referencing system. This turns out to be adequate if you:

  1. only write in a linear fashion, or
  2. never add cross-references, or
  3. don't care about [14] cropping up before [5]
