New Chemical Process Could Make Ammonia a Practical Car Fuel

carlhaagen I see a problem here... (380 comments)

"For a fraction of the cost". There is no money to be made by selling the world something it needs for just pennies. Ammonia is available everywhere for pennies, and I suspect sodium amide is available for pennies as well. This doesn't equal good business when you can still sell gasoline for some orders of magnitude more, and as such you can be damned sure no one will ever allow this to be a legit fuel for cars.

Ask Slashdot: What Would It Take For You To Buy a Smartwatch?

carlhaagen Re:Acceptable battery life (427 comments)

There's nothing hard about it at all. I just don't like being at the mercy of a power socket every single day. A device that requires recharging once or more per day isn't a mobile device, it's IMMOBILE. You can't leave civilization (read: trekking, outdoors etc.) with a device like that and you can't rely on it in situations where you leave home for a day without having to carry a charger with you as well.

I'm happy for you. My iOS phone lasts 5-6 days as well.

Ask Slashdot: What Would It Take For You To Buy a Smartwatch?

carlhaagen Acceptable battery life (427 comments)

The Android-based things we've seen so far need to be recharged at the very least once a day. I can't even stand the thought of owning a smartphone model that requires recharging every day.

Ask Slashdot: How To Bequeath Sensitive Information?

carlhaagen Weird questions... (208 comments)

You state that you have a long career in IT, and at the same time you ask how to electronically hand over information generated within IT. Among those things, you even claim that you have passwords, meaning that they have been stored insecurly. This has "IT Janitor" written all over it, or possibly a concocted story.

One Developer's Experience With Real Life Bitrot Under HFS+

carlhaagen I've also had this happen with HFS+ (396 comments)

An old partition of some 20000 files, most of them 10 years or older, in where I found 7 or 8 files - coincidentally jpg images as well - that were corrupted. It struck me as nothing other than filesystem corruption as the drive was and still is working just fine.

US To Auction 29,656 Bitcoins Seized From Silk Road

carlhaagen Re:If Feds sized BCs, spend from backup? (232 comments)

The coins aren't contained in the wallet as such, but rather they reside in the blockchain. The wallet holds the private keys that allow you to move coins away from their public address counterpart. Once that is done, it doesn't matter how many backups of that wallet there is, because the coins are already somewhere else - already locked to another private key in the blockchain. Also, his coins have already been "secured" (moved to another address), so there is nothing anyone can do.

Also also, DRP is in custody, without access to the internet, and thusly was never able to do anything.

Life Sentences For Serious Cyberattacks Proposed In Britain

carlhaagen Smells like a planned way to... (216 comments)

...label pretty much any hacking as "life-threatening or endangering the nation's security". I mean, we've seen this before, in how people who pirate TV shows and software are by American organizations pretty much labelled "terrorists".

Norwegian Infectious Disease Specialists Have New Theory On HIV In Africa

carlhaagen Re:Reasonable, no smoking gun. (118 comments)

A contributing factor is probably their outrageous belief that copulating with virgin girls "dispels" the HIV.

OpenSSL Cleanup: Hundreds of Commits In a Week

carlhaagen Re:Quatity is not quality (379 comments)

It seems you're not familiar with the process of software development. You just don't issue one single commit containing a billion changes. It's a step by step process, for several reasons, most importantly the mechanic and iterative process of searching for bugs.

Ask Slashdot: What Tech Products Were Built To Last?

carlhaagen Early 2004 G4 iBook (702 comments)

Still runs just as good as the day I bought it 10 years ago, incl. the HDD that came with it. The CCFL backlight in the screen has lost a lot of brightness output, though.

Ask Slashdot: What Tech Products Were Built To Last?

carlhaagen Old computers and certain new components (702 comments)

All of my old home computers I kept are still in 100% working conditions - a few C64s, Amigas, Ataris etc. In terms of more modern computing, my best example would be my home server/router which is a 14-15 years old Abit BF6 motherboard with a low-power passively cooled P3-600/133 and 512MB of RAM. This machine and its original 200W PSU saw 8-10 hours of use 5 days a week during 2000-2004, and from 2004 to this very day - 10 years - it has been running 24/7 as my home server/router, without failure. The only thing that has been replaced in that machine is the original HDD I bought with it, a 12GB Fujitsu drive, that died in 2010, after 10 years of service. They don't make 'em like they used to.

This 1981 BYTE Magazine Cover Explains Why We're So Bad At Tech Predictions

carlhaagen *Sigh* the cover was symbolic art (276 comments)

The cover art was delivering the message of the "wrist-worn/hand-held computer". It was neither joke nor prediction; it was symbolism.

Interview: Ask Theo de Raadt What You Will

carlhaagen Re:Smoother Chroot and Sftponly integ into OpenSSH (290 comments)

Small explanation: what happens is that when the SSHd matches the user's login group successfully, it forcefully switches over to the internal sftp component instead of the default external subsystem, which in turn makes it possible to chroot the user to his/her home dir without having to place a plethora of system files in each user's home directory.

Interview: Ask Theo de Raadt What You Will

carlhaagen Re:Talk to the hardware vendors (290 comments)

Proper support for power-saving clients comes down to buffering outgoing packets until the client asks the AP for them, rather then instantly sending them to the client which may or may not be asleep at that point. This is not a driver firmware issue, it's a fundamental stack problem and lies entirely in the hands of the OpenBSD developers.
