luser001··on How I spend my first 5 minutes on a server
Why do you say a VPN server is more secure? Which one?

I, for one, trust ssh more than any other software wrt security, especially with password login disabled. Disclaimer: I am not a security expert.

Are you insinuating that the user could have used sudo access to install a backdoor of some sort? If so, changing the password won't stop them either. Am I missing something?
luser001··on Map Shows Where 220mph Trains Would Go in the U.S.
The fuel efficiency of a vehicle rolling on rigid steel wheels on a rigid steel track is FAR higher than that of a vehicle rolling on pneumatic tires on asphalt.

The number I have seen quoted is that a train can move 1 ton 400 miles using 1 gallon of diesel.

luser001··on Map Shows Where 220mph Trains Would Go in the U.S.
High speed Internet access whether DSL, cable, or ethernet requires "a copper wire in every home" [ok, fiber requires a glass wire, but it's still the same concept].

Why do you say copper wire is useles?

luser001··on Evernote hacked
Pretty cool tool! My passphrases (omitting spaces between words) get a score of 2. But if I drop the vowels, the score goes to 4 and crack time to 'centuries'.

I wonder if this is a good way to create passphrases. Anybody want to chime in?

luser001··on Torvalds clarifies Linux's Windows 8 Secure Boot position
Wow, I think I learned more about Linux + UEFI from this comment than anything else so far. Thanks!

> Why? Do you really consider it worth $100 to you just to prevent someone else from getting $9900, or do you just value $100 so little that you are willing to round it down to $0?

Not the original commenter. But yes to both.

Look up multi-round games. Strategies fit for single-round games don't work in multi-round ones. Many of our strategies and heuristics are meant for multiround games, which is what most life interactions are.

By overanalyzing the experiment and treating it "just" as a experiment, imho, you are actually defeating the point of the experiment. ymmv, just my 2 cents and other disclaimers.

luser001··on Tom's Obvious, Minimal Language (like INI, only better)
You seem picky. :) But check out libconfig. Maybe it'll work for you.
luser001··on Stop Using Small Font Sizes
Thanks! I didn't know that a CSS px wasn't the same as a screen pixel.
luser001··on Stop Using Small Font Sizes
Hear, hear! :) I'm really happy to see this get to the front page.

But why pixels (px) and not points (pt)?

I made a site using 12pt text and it looks good everywhere (ipad, iphone, chromebook, linux, windows, mac).

I suspect 16px is going to look too small on a Retina Macbook (I don't own one, so I wouldn't know).

luser001··on Spotify and Facebook: Is that phishing?
> you might end up getting burned by the extension when travelling.

Good point. This could happen. I'm assuming by "burned" you mean "unable to login". If so, you can always type in your home country's domain into the webapp version and get the correct hashed password. I agree this isn't ideal. Just saying that there's a plan B.

luser001··on Spotify and Facebook: Is that phishing?
> Doesn't seem like a good fit for the paranoid.

Agreed. But OTOH it's a very lightweight solution, which is an advantage. And in any case, it's MUCH better than using the same unhashed password everywhere.

I'm claiming that using PwdHash is strictly better than not using it. YMMV.

luser001··on Spotify and Facebook: Is that phishing?
Amazing.

Also, this is yet another privacy threat that I dodged because I use the PwdHash extension (https://www.pwdhash.com/). You type the same password for all sites, but the extension invisibly uniquifies them on a per-site basis.

luser001··on Why is Spotify chugging upload bandwidth when it is not streaming?
I didn't see it uploading a lot over about 20 minutes. (1) I was listening to an obscure album, (2) I listen to small number of songs repeatedly, although I have a large number "starred" and in playlists from previous installs of the app.
luser001··on Why is Spotify chugging upload bandwidth when it is not streaming?
Awesome. Ubuntu even has packages for this. Thanks for the tip!
luser001··on Why is Spotify chugging upload bandwidth when it is not streaming?
Maybe somebody else in the house is running Spotify? [See "bufferbloat": http://news.ycombinator.com/item?id=2088389]
luser001··on Why is Spotify chugging upload bandwidth when it is not streaming?
I use Spotify on Ubuntu Linux.

Looking into how it behaves there.

luser001··on Why HN was down
> I eventually realised that typing sudo every time he touched a box was no defence against doing the wrong thing.

IIRC, sudo logs all commands to syslog. Which might come in handy. Yes, root commands will be logged by bash to .bash_history, but there are limits of # of commands lots, what happens if you are logged in multiple times into same account etc.

Anyway, that's why I like sudo.

luser001··on Why HN was down
Agreed, infinite loops are a little hard to protect using asserts.

When I hit the first infinite loop bug on a code path, I frequently add code to assert that the number of calls is less than $A_LARGE_NUMBER to catch future occurrences of the same root cause.

luser001··on Why HN was down
I use assertions to protect against things like this.

I liberally sprinkle my code with assertions (CS theory calls them pre-conditions and post-conditions, iirc) to crash early if the system is an invalid state.

One my pet peeves is that few programmers seem to love assertions like I do. Would love to see to comments on this.

luser001··on Why Do Cars Have Brakes?
IIRC, even manual transmissions have a speed limiter that will prevent you from shifting into 1st at 100 mph.
luser001··on Why Do Cars Have Brakes?
Kids, listen to this man. :)

When I was newbie, I didn't downshift and was instead keeping the brakes lightly pressed. After a few mins of this, when I pressed them a little harder to slow down more (at a turn), the pedals sickeningly went way more than they were supposed to. Remembered in a flash what had happend. Thankfully, I was able to pull over and let the brakes cool a bit.

The brake fluid had overheated and turned into a compressible liquid (if you remember your Pascal's Law (iirc), hydraulics can only work if the fluid is nearly incompressible).

luser001··on Why Do Cars Have Brakes?
What car? Without cruise control? My car doesn't downshift unless I've set it on cruise control at an intermediate speed like 55 mph and it is a long downhill slope.

I understand why: it's most efficient to drive in the highest gear even at speeds as low as 45 mph in a manual. I would imagine it's similar for automatics too.

luser001··on Setting Up a Local Development Environment in Chrome OS
Ummmm. It is possible to run a full-blown Ubuntu including arbitrary kernels etc. Some are doing it.

This is just an easier method if all you want is access to a powerful Debian userland: it turns out that Debian already solved the problem of creating a self-consistent cross-compiled directory tree ages ago so it makes sense to reuse that solution here.

Can you get 6h battery life for $250? I have the Samsung one and it delivers on the battery life promise.

Second sentence of the paragraph that follows the one you pasted.

luser001··on AT&T Will Force Your Data Plan For Your Unlocked Out-of-Contract "Smart" Phone
http://venturebeat.com/2010/12/21/fcc-net-neutrality-is-a-go...

I wonder if this is legal because of the net neutrality ruling on mobile networks that the FCC put out a couple of years ago.

luser001··on Computer Science PhD trends
You can do EB-1, EB-2 only if you first acquire a H-1B visa. Wrt which you wrote: "Acquiring a H1B visa to work in the United States is not hard. When, I (a foreign born student) graduated and applied for an H1B visa, it took ten days for it to get approved."

Actually, the difficulty varies from year to year and from company to company and from subfield to subfield. So yes, people do suffer from the status quo.

Just throwing this info here in the interest of completeness.

luser001··on Ask HN: How do you deal with your mediocrity?
Complex topic. In a nutshell, you should care that you're mediocre only if your competing with others. If not, why should you care?

After you leave school, the need to be not-mediocre will become less acute, because life is less competitive than we're led to believe in school.

Basically, as you grow older, you'll stop competing and start living.

Not really sure if this helps. Good luck!
