But that's because IBM has a strong presence in the SQL standard committee and can nudge it to standarise (post-factum) things they already implemented in DB2.

Since all of the previous states are there in the repo history, you can make that gif yourself at any moment!

Postgres at least will store rows roughly in insert order. So whether you're using integers or UUIDs for primary keys won't affect on-disk layout. When scanning the index, the data…

What is the epiphany here? What is the insight or enlightenment to be gained from this story? I have my own, but I'm curious about what people believe is the moral of the story.

That's also why, when you go to the movies and it turns out tickets cost the same regardless of the film, you should go for the one with the longest running time.

One of the important reasons Postgres connections are serviced by a separate process is that if that process segfaults, you only disconnect other connections (because if might have…

Almost two years ago the "The Pulse of Spain" was made, based on the same idea (disclaimer: the designers of this are also designers for our product (and dear friends)). It's in Sp…

Logs subpoenaed from your ISP show that you were using Tor between 3:10 and 5:23 PM on 02/05/2012. Logs from forensic analysis of a breakin to EvilCorp show that the attacker came …

Why can't you use a connection that has issued LISTEN for anything else? In fact, I'm fairly sure you can use it normally. We're using NOTIFY to broadcast database changes to servi…

BTW, I think at least in Peninsular Spanish you'd say "Viva Brasil" (omitting the article).

We wrote a similar utility for our ORM-for-SaaS library some time ago, using lxml if available and falling back to ElementTree: https://github.com/ducksboard/libsaas/blob/master/li…

Not really, the ones calling down to date_trunc should be marked as STABLE, since the underlying function is STABLE. psql=$ \df+ date_trunc Schema | Name | Result data type | Argum…

I've been thinking about switching to sup a few times, but the inability to sync changes back to the IMAP server is a deal breaker to me. If I mark an email as read in sup, I don't…

We have one on https://demo.ducksboard.com/ too :)

Doesn't matter if it's MD5 or SHA512. You can extend either hash function in the exact same way ( http://en.wikipedia.org/wiki/Length_extension_attack )

What I meant is that using PKCS#5 padding ("N bytes of a value of N") will make it even more susceptible to a CBC oracle attack. I'm not nearly qualified to talk about that stuff, …

Once this TODO is completed and real PKCS#5 is used, CBC padding oracle attack? https://github.com/mothran/bunny/blob/master/libbunny/AEScry...

I thought most disks nowadays support Secure Erase, so there's no need to futz around with dd. https://ata.wiki.kernel.org/index.php/ATA_Secure_Erase
