I think this should be Spinn3r’s logo: FYI. I found this on pizdaus.com with no permalink or attribution.
In the last month I’ve found two bugs that can cause MySQL to lie about Seconds_Behind_Master (at least on 4.1.22). Let’s recap: Maximum Packet Size on Slaves If max_allowed_packet is large on the master but smaller on the slave the slave won’t be able to read the data from the master. What happens is that [...]
So far Ron Paul has raised $852k in five days. They’re targeting 1M. If you think you can help donate here. In a little more than five days, you raised over $852,000 online for the Ron Paul presidential campaign. Our original goal was $500,000, but you blazed past that amount in just a couple of [...]
When we migrated to 64bit Debian Etch about two months ago we noticed that some of our database boxes were paging even though they had plenty of memory to perform the tasks at hand. The boxes had 8G and we told INNODB to allocate 7G to the buffer pool. The problem is that after using [...]
Today’s Open Source hero award goes to Kosmix for OSSing their GFS implementation: Applications that process large volumes of data (such as, search engines, grid computing applications, data mining applications, etc.) require a backend infrastructure for storing data. Such infrastructure is required to support applications whose workload could be characterized as: Primarily write-once/read-many workloads Few [...]
I didn’t see this anywhere in the MSM today. Did you? Iranian president Mahmoud Ahmadinejad Monday afternoon met with a group of Jewish rabbis who gave him a silver grail as a sign of friendship. The president is currently in New York to address the United Nations General Assembly.The rabbis carried a placard which read, [...]
When you have a large website it seems vendors/spammers are constantly doing a whois on your email and sending you spam to hock their wares. Today I received this fun little email: You are losing business to your competitors because your web site is not showing up high enough on the major search engines. We [...]
Remember the other day when I blogged about MySQL being broken with binary replication? I was wrong. It might actually be functional (I still haven’t tested) but the problem was more difficult to diagnose than I originally thought. Here’s what was happening. The default slave_net_timeout value is 3600 seconds. The network was being congested due [...]
This has to be a joke. Apparently, Bush uses a teleprompter with phonetic spelling: When Mr Bush addressed the UN General Assembly today, the White House inadvertently showed exactly how – with a phonetic pronunciation guide on the teleprompter to get him past troublesome names of countries and world leaders. The White House was left [...]
What’s the deal with replicating binary data in MySQL? Is anyone out there doing this successfully? We ran into an evil problem last night with 4.1.22. Apparently, if you replicate binary data (in this case a gzip stream) it will break replication. The data inserts correctly on the master but fails to insert correctly on [...]
We know there are eight fallacies of distributed computing – but I think there’s one more. A physical machine with multiple cores and multiple disks should not be treated as one single node. Two main reasons. First RAID is dying. You’re not going to get linear IO scalability by striping your disks. If you have [...]
There’s a new YouTube group called CopWatchers where people people can upload videos of police harassment and brutality. What an awesome idea! This video itself is pretty interesting:
Designing a scalable system means nothing until you put it into production. There are a number of real world problems that come into play when you have a system live and running and under load for months which you’d never anticipate otherwise. Today we hit one. There’s a bug in MySQL where it reports healthy [...]
I like this joke in the ‘watch’ man page: You can watch for your administrator to install the latest kernel with watch uname -r (Just kidding.)
I sent off an email to the Facebook Fund platform submission email address and received this response. During this process, however, it has become clear that we will receive proposals which contain similar or even identical ideas. As a result, and in order to protect other developers and us from claims that we or anyone [...]
This is awesome. I betcha Microsoft wrote this system.
The NY Times has a new article on Alan Greenspan’s new book in which he slams the Bush administration: Mr. Bush, he writes, was never willing to contain spending or veto bills that drove the country into deeper and deeper deficits, as Congress abandoned rules that required that the cost of tax cuts be offset [...]
I was invited to a Google Engineering Open House yesterday and heard more discussions about Google’s infrastructure from Jeff Dean. Not to disappoint, they lifted the kimono a little bit and released some more data points on their impressive infrastructure. For example, Google Translator’s accuracy is improved 0.5% for every doubling in training corpus size. [...]
Apparently, Yahoo has acquired BuzzTracker. This makes for the 4th memetracker acquisition including Newroo, The Personal Bee, Blogniscient, and now BuzzTracker. I guess the going price for a memetracker is $5M. Interesting that they only track 100k. Spinn3r/Tailrank is indexing north of 1M. More on that shortly…. Of course you can read the full story [...]
Apparently, VECO CEO Bill Allen testified that he spend $400k to work on Ted Stevens’ house: Bill Allen, former chief executive of oil services company VECO, testified that he spent more than $400,000 to bribe state legislators and for work at Stevens’ house in the ski resort town of Girdwood. He said VECO also paid [...]
