OpenSSL Cleanup: Hundreds of Commits In a Week

carlhaagen Re:Quatity is not quality (374 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 (694 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 (694 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 (275 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.

Interview: Ask Theo de Raadt What You Will

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

There is no need for third-party tools for what you want to achieve. While the solution is a bit ungainly, all of it is already supported by OpenSSH and its sftp subsystem. This is how I configured things on my system:

First off, add a group that you call f.e. "sftponly". New users that are to be allowed only sftp access should have "sftponly" as their login group, and have /sbin/nologin as shell to deny them shell access. Their home directories should be owned by root:sftponly, and within the home dir you then create relevant user-controllable directories which should be owned by :sftponly.

Secondly, the sshd_config magic that makes the whole charade work:

Subsystem sftp /usr/libexec/sftp-server
Match Group sftponly
ForceCommand internal-sftp
ChrootDirectory %h

carlhaagen OpenBSD and Wi-Fi (290 comments)

I've been using OpenBSD as my wireless home router, server and development platform since 2005, and can from 9 years of experience safely say that the current state of OpenBSD's Wi-Fi drivers and 802.11 stack is troubling. On one hand, most chipsets out there have rudimentary driver support in OpenBSD, including WPA2 and CCMP facilities. On the other hand, the 802.11 stack still lacks 11n support (minor problem) but what's much worse is that while only two of the drivers - ral(4) and athn(4) - state that they can handle power-saving clients when running in HostAP mode, none of them actually do it properly. None of the support ral(4) chipsets can handle power-saving clients despite what the ral(4) man page claims, and while athn(4) works slightly better it's still flaky with unreliable results, no matter what wireless chipset the client uses. The effect is that OpenBSD is useless as a wireless access point without having the clients pull one of several tricks available to avoid them from entering power-saving mode, as have been posted and explained by troubled users on the OBSD mailing lists regularly over the years.

I understand that Wi-Fi portions of OpenBSD aren't exactly prioritized, but are these issues even on the roadmap?

The Next Keurig Will Make Your Coffee With a Dash of "DRM"

carlhaagen Re:Why? (769 comments)

It's about the cost, not the coffee or the effort. High price tags attract people who suffer the "spender syndrome" - dishing out a lot of money on something even plain or generic gives these people a feeling of being above the average, being set aside from the rest of us, of enjoying something that is "exclusive" only to their kind.

It's like when you find the exact same piece of generic furniture sold at (but not designed by) IKEA in some upstreet furniture shop - IKEA would call it "ROBUST" (or whatever) and sell it for $89, while the other "boutique" will call it "Multimedia bench in Nordic pinewood" at thrice the pricetag. People with money will buy it, and they will feel like they did a better deal than paying $89 at IKEA. It's one of the oldest tricks in the book of retail.

Apple Drops Snow Leopard Security Updates, Doesn't Tell Anyone

WV Senator Calls For Ban On All Unregulated Cryptocurrencies

carlhaagen Re:Can anyone say money laundering? (240 comments)

You're suffering a fundamental misunderstanding of the Bitcoin protocol. The entire currency as it stands at any point in time is contained within the blockchain. Every single minting of a coinbase, and every single transaction ever made; from where, to where, at what point, how much etc. Also, AML already demands exchanges to able to supply identification for each account that ever does a BTCfiat exchange.

WV Senator Calls For Ban On All Unregulated Cryptocurrencies

carlhaagen Gee, color me surprised (240 comments)

A banking goon wants cryptographic currency - a technological currency the banks cannot gain any control of - to be banned. How about that. What's next? A system for banning competition in business?

Slashdot Asks: Do You Label Your Tech Gear, and If So, How?

carlhaagen What difference would a label do? (250 comments)

Someone obviously picked it up and decided NOT to bring it to the reception or Lost And Found. How would a label on the item matter? How were you thinking when you wrote this up, Tim?

Tesla Model S Caught Fire While Parked and Unplugged

carlhaagen Was it the car at all? (329 comments)

With the fire not originating in anything connected to its electrical system, why are they assuming that the fire originated in/from the car at all? It sounds highly unlikely, and more like vacuous sensationalism.

Germany's Renewable Plan Faces Popular Resistance

carlhaagen Re:How much is this going to cost? (176 comments)

The argument isn't over power lines, it's over house owners on the countryside not wanting their scenery ruined.

Germany's Renewable Plan Faces Popular Resistance

carlhaagen Do what the Swedes do (176 comments)

Dig the power lines down instead of hanging them on pylons. In addition to pandering towards the senses of complaining house owners, it also solves the problem of critical outtages during storm seasons, which is why the Swedes are in the middle of dismantling pylons and moving their grid under the surface.
