Anyone else blocked by the stupid cloudflare scam about not having 3rd party cookies enabled meaning you have virus on your computer? And preventing them from reading the article?

Huh? I browse constantly with third party cookies disabled in Safari and Chrome and never have a problem. I can see that site perfectly. And that's certainly not how CloudFlare decides that your machine is likely to be infected. What are you seeing when you visit the site?

I was browsing with firefox with 3rd party cookies disabled, and I saw this message a few times. What irks me and triggered my kvetching is that I "played the game" and did submitted the captcha 3 times and it still didn't work. Twice in Firefox and once in Safari in private browsing mode.

Here is a screenshot, with my I.P. address at the bottom:

It looks scam-y too with the "google pays me $x a day" and "automated profit package" ads.

P.S.: I remember seeing it on a blog post on jgc.org at least once, as well as on joyoftech a ago but not today.

Interesting article but pls fix website for mobile readers http://twitpic.com/9o9q35 I would have commented on your blog but on Firefox the "about me" floats over the disqus column so I can't.

I've noticed most HN posts from blogs suffer this issue... I was thinking of a "Your Site Doesn't Work On Mobile" notification service...

Thanks. I'll take this up with the folks in San Francisco and see why you were seeing that.

Personally I wouldn't trust a microSD card for any production role beyond being a bootloader. You'll be paged one day only to find you had to make a time-consuming visit to your co-lo, and that all your data was irretrievably gone. The solution to this is to have one "real" PC acting as a NAS and serving iSCSI. You would have to divide the extra cost of this PC across all the ARM servers you have.

Micro SD are notoriously bad for server usage, they are designed to store infrequently changed files for a while, like mp3 collection, cameraphone snapshots, apps etc... Going with a brand name might help. In order to extend their lifespan, you might want to minimize the writes by disabling some logs and the "last access" updates on files (`noatime` for "no access times"). Some examples: http://tombuntu.com/index.php…

Instead of disabling the logs, you can put them on a tmpfs. You'll lose them if the machine crashes or reboots, but it's still better than not having them at all.

If someone (looking at SanDisk) were to make a range of SD cards for servers and lightweight ARM desktops that would be of real interest. Because the current stuff out there for phones and cameras is of variable quality and is about the worst thing about these new lightweight arm systems.

SD is my main concern with these hacker boards, I mentioned it in a previous item. They shouldn't really be relying on this sort of basic flash memory, but I know why... it's accessible and cheap - plus many uses won't be 24/7. Time will tell, but it feels like a time bomb that will affect people who don't know about it (i.e. those that don't know about configuring these devices for minimal writes).

YES DO IT (I would help if I had spare time, I'll just wish you good luck instead)

If it had a lot more memory that would be interesting. Though really you can get a 256Mb VPS for £5/month http://prgmr.com/xen/ and you don't have a setup charge or unreliable hardware.

I was thinking about this as well... maybe not in comparison to cheap providers whose performance are variable, but for £12/month from Linode you can get a 512mb VPS with 20GB of disk space. How does the performance of this ARM box compare to a Linode?

Well, for a ballpark figure:

md5sum of 3.4 kernel.tar.gz (average of three runs)

512Mb Slicehost 2.2Ghz Quad-Core AMD Opteron(tm) Processor 2374 HE = 0.275 seconds

512Mb BeagleBoard XM 1GHz Cortex A8 = 2.023 seconds

Checkout TonidoPlug2 (http://www.tonidoplug.com/tonido_plug.html). It has 512 MB DDR3 RAM, Gigabit Ethernet, WiFi b/g/n and in-built enclosure for SATA II HDD. You can boot it directly from the SATA instead of internal flash. All the right things you need in a personal server. Also it runs debian squeeze.

"Micro-SD card performance is highly variable, and generally rubbish" Agree with that. I use a pandaboard as a build server and I felt it is a lot efficient to use NFS than running off an SD card. Ewan, have you tried USB HDD instead of SD card?

Pandaboards run much faster with USB hard drives instead of SD cards. That's what I hear from lots of knowledgeable people, anyway. I've not actually run any benchmarks though.
