I am new to MongoDB but this book has been helpful in evaluating and learning about how to scale with it. At work we’ve been thinking about using it for some projects but it was important to investigate and review it in more detail before we jumped into it and added it to our stack. Overall, it’s a great book on Mongo scaling, succinct and complete. It doesn’t elaborate on every possible scaling topic, but it’s enough detail to make important architectural decisions. Mongo is a great new technology, and this book is a good companion. For more info on using mongo in general, check out “MongoDB: The Definitive Guide.”

I actually started this post just to have somewhere to embed the issuu code, but ended up like it so much I created a “real” blog post. Check it out below! All I did was upload an insurance pdf I had in my documents folder and it magically turned into an embeddable flip book.
If you want to see it on a page by itself, check out this link.
A few days ago an apple employee gets drunk and forgets his phone at the bar. It’s not just any phone though, it’s the next generation iPhone not to be out for months. Given how secretive Apple is, I’m sure this person is in a world of hurt right now. I was kind of surprised when I saw the story on Gizmodo a few days ago, but was even more surprised when I saw it in the NY Times this morning. Someone is going to be getting a serious spanking from Steve Jobs.
BTW there’s no evidence that the apple insider was drunk, but for his/her sake I hope they were or had some better excuse for leaving a very secret prototype in a public place.
As google seeks to dominate all things digital, it gets one step closer. This time with language translation. It’s actually quite impressive to see the results. I read this article from the NY Times and was pleasantly surprised.
Human Translation of a passage from the Le Petit Prince
On the first night, I fell asleep on the sand, a thousand miles from any human habitation. I was far more isolated than a shipwrecked sailor on a raft in the middle of the ocean. So you can imagine my surprise at sunrise when an odd little voice woke me up. It said: “Please … draw me a sheep.”
- Wordsworth Children’s Classics, 1995
Google’s translation of the same passage
The first night I went to sleep on the sand a thousand miles from any human habitation. I was more isolated than a shipwrecked sailor on a raft in the middle of the ocean. So imagine my surprise at daybreak, when a funny little voice woke me. She said: “If it pleases you … draw me a sheep!”
It’s amazingly similar! Sure the original book may have actually been part of the training data, but you look at the other examples and Google out performs the competition most of the time.
If you came to this site in the last month or two you might have noticed some weird things happening. You look at a post and then you are redirected to some random site trying to sell you something. Turns out I got hit by a hacker targeting WordPress on Media Temple. Almost 1/4 of all WordPress blogs on my host got hacked..lucky me! If you are running WordPress don’t forget to keep up with security updates and keep your server perms in check. I haven’t posted on johnarroyo.com for months because of work, but that also meant I hadn’t properly updated my WordPress installation in a while either.
If you were one of the unlucky folks who got hit with some sort of injection or other attack, check out these posts. They’re helpful in cleaning up your site and keeping it secure. If you didn’t get hit, be proactive with your site security!
BTW I hope you like the new look of the site, I changed my theme and customized it a bit…it was about time for a refresh
If you are using a mac or PC and want to add Vorbis (*.ogg) and FLAC (*.flac) playback to iTunes and Quicktime then these two apps are very handy. I just recently installed them and they work great. Fluke is used to add FLAC playback and XiphQT is used to add Vorbis playback. Instructions to install and use these apps are included on the Fluke and XiphQT websites.
FLAC and Vorbis are both open source compression formats. The popular mp3 and AAC (Apple) formats both have proprietary technologies in them. FLAC is popular with the classical music sect because it is a lossless format. 100% of the audio is preserved but less space is needed tp store it. Some popular artists like Brian Eno and Perl Jam have began to embrace FLAC as well. Vorbis is a lossy compression, like mp3, but it does not use propriatary technologies and some say it sounds better than mp3. For more info on these formats check out these links: FLAC, Vorbis.
