Yeah, I definitely plan on follow-up posts with any changes that occur.

As for engines, I used cocos2d for all of the 2d (imagine that) stuff like menus and the HUD. The 3d objects I made using blender, modified some code I found online[1] to load them into the project, then pretty much just cobbled together a physics and rendering engine by hand. Good times.

I use SSH keys to log into Linux and OS X boxes all the time, servers and otherwise. And boy have I wished there was an easy SSH server to run on Windows.

You have to log into remote boxes these days and SSH keys are the best way to do that.

I find it just plain distracting.
Uhm, MySQL indexes efficiently sort in both directions. You can use a composite index to achieve an ordered set with a set of while conditions, even with millions of rows. As long as the app is only fetching like 10 rows, it should be lightning fast.
In most systems, you're probably already doing it. Any ORM that has a level 1/2 cache built in (like Hibernate and EHCache/terracotta/etc or SQL caching in Rails) is storing the data in more than one place. If the data is in the cache (or if the cache fails for whatever reason), you're in the same boat you are now.

If you're just using redis for write-through caching/memoizatoin and there's some failure, you still have the answer in hand and can return it to the user, you just lose the benefit of the speedup from the cache.
Indeed it is, thank you!
A composite index will work wonders for this situation. EXPLAIN is your friend.
Yes, you can tell it to either make a copy to disk ever N seconds or use an AOF mechanism, but that doesn't mean it's in sync with your database. Depending on how your DB can get updated, you'll want to think about how the cache can get stale and whether you're expiring data in redis periodically, or removing keys/using different hashes for keys. The specific way to do this will depend on the app that you're using.
This is part of my reply to swaits from his accurate review of the WakeMate 1.0.

"Thank you for your considerate e-mail and your respect for my privacy (by bcc-ing my e-mail).

It's funny that you e-mailed me, since my boyfriend and I read your story on hacker news, about an hour ago and thought about how they could be launching a new product in the ill-be-gotten gains of defective wakemate sales.

The experience I had was very similar yet, I still have my two wakemates (defects and all). I have no desire to send either back until I get a replacement charger, prepaid postage and working device. I have explained that to their customer service. Basically, I am holding them ransom; though, since they don't work, I don't think I have the upper hand.

If you would like, I can send you one of mine. I don't know if you like/play portal, but it could become you companion band.

Thank you for speaking out and letting other's see what has become of this. It had so much promise and then went horribly wrong."

I feel that everyone should know of this service atrocity (yes! An atrocity!). I worked many years in customer service, and I know that I would not be in business, let alone retain customers, with this type of service. The fact that customers paid for a device/service that has not delivered the features that were advertised; and, the Wake Mate company has not come close to satisfying their current customers, with broken devices that have not been replaced, nor a charger that won't cause a fire, one would wonder what they will do with the 2.0 version?!
Except at taking risks, it would appear.

I wish they would stop calling those data structures functional. Just call them immutable. It's the other way around. Functional languages use immutable data structures. One can use those "functional"data structures with any programming paradigma (not sure how to use them in Prolog though).

I really like what GitHub do, though in this case I would say that the GitX client (forked one) is way more productive and overview:aböe IMO. I even managed to teach my MBA partner how to use it - this one is actually a bit more confusing than GitX interface. Abstraction is not always for the good, but a very good try at least.
Wait until you hear about 2711 Centerville Road, Wilmington, Delaware.

Such shady entities registered there include "Level 3 Communications", "California Pizza Kitchen", "The Walt Disney Company", "Dole Food" and "Qualcomm".

Seriously, all those companies are Delaware corporations who maintain their registered office at that address, despite the fact that their CEO has probably never visited that address in their lives.

This is such a common occurrence that it hardly merits notice. Even if you throw in the observation that dubious businesses favor incorporation in Wyoming (which has no corporate income tax, franchise tax or tax on corporate shares), that's still not saying much.
Microsoft launches Cloud based Office 365 worldwide on Tuesday
I work on a project with 3 other devs; an xcode conflict is an "oh, bummer" moment, but not a hairpuller. 90% of the time we've both added files, and the merge is as easy as "choose both."

It's still the sort of thing where you want to check out, change the project, and check back in quick to avoid conflicts. I can imagine it getting worse with far-distance branches though.

It's not too different from a makefile, except you'll get a better error message when you muck up your makefile.

He's actually right; dopamine is our primary pleasure reward system. In addition to interacting with GABA alcohol triggers dopamine in the same way caffeine, amphetamines, and even ecstasy do. And please don't tell me you think Opiates have no effect on dopamine...most drugs just keep dopamine around longer by blocking the reuptake. Opiates literally release the stuff. Hence the massice euphoric state.

Yeah, already have greasemonkey and the only thing I have to do to "publish" files is to save them with the same name.

This project is a lot of work for zero benefit.
So actually it's much worse than Greasemonkey.

Also, with GM you can just save the script with the same filename and it'll use that instead.

This project is 100% useless.
I would agree that it's not a very complex or innovative idea. I'm assuming Facebook is intentional in not doing the same sort of thing, aiming for simplicity (everyone in one circle).

Calling them "persistent data structures" is probably more useful.

Prolog has "difference lists", which are (currently) pretty unique to Prolog. Its special case of variables that can be mutated, but only once, has interesting implications.
I appreciated your article too, but I have a different opinion on the value of luck.

The "big players" don't trust to luck when the release an app, especially if they've poured in thousands in dev costs. They use paid installs to push onto the charts, and then them momentum of the app takes over from there.

Flask doesn't have any sort of database interaction built in. You do it all with the more general Python tools. SQLAlchemy is a common ORM for Flask, probably because of the Flask-SQLAlchemy extension. I've never done any migrations with Flask, but I would think http://code.google.com/p/sqlalchemy-migrate/ could do it.
Kitchen interior design ideas
Kitchen Designs in one of the most desirable home improvement projects for many home owners.
Flask has become my framework of choice because it's incredibly well designed, the code is clean, and also because it's decoupled from an ORM.

Rails and Django emerged at a time when RDBMS ruled, and they were both built around an ORM. Now you have more database options that have less of an impedance mismatch, but because Rails and Django are so ORM-centric, forgoing the RDBMS in favor of another option means you now have a framework mismatch.

Graphs are a much more elegant way of storing relational data. With graph databases you don't have to mess with tables or joins -- everything is explicitly joined.

For most Web development projects, I have shifted from a relational database to a graph database as the primary datastore, and use Redis, Memcached, and MongoDB for specialized purposes when called for.

Neo4j Community Edition (http://neo4j.org/) is open source and now free, and pairing it with the TinkerPop stack (http://www.tinkerpop.com/) is ideal.

With Neo4j you can now store 32 billion nodes (http://blog.neo4j.org/2011/03/neo4j-13-abisko-lampa-m04-size...) with 2 million traversals per second (http://www.infoq.com/news/2010/02/neo4j-10), and you can use Gremlin with it (the graph traversal language), which let's you calculate PageRank in 2 lines -- to see what you can do with Gremlin, check out this 10 min screencast (http://www.youtube.com/watch?v=5wpTtEBK4-E).

For tabular data, relational databases rock. But the relational model doesn't align well with object-orientated programming so you have an ORM layer that adds complexity to your code. And with relational databases, the complexity of your schema grows with the complexity of the data.

The graph-database model simplifies much of this and makes working with the modern-day social graph so much cleaner. Graphs allow you to do powerful things like find inferences inside the data in ways that would be hard to do with relational databases.

There is an open-source Python persistence framework in the works called Bulbs that connects to Neo4j through the Rexster REST server, and there are binary bindings in the works as well. There is also a Python open-source Web development framework for graph databases called Bulbflow that is built on Bulbs and Flask, which will provide stuff like authentication and authorization, in a graph-DB way. Both frameworks should be released in the next few weeks.

I might be a little old school but I wouldn't seriously let a complicated system take care of schema migrations for me. Well, actually I do (in a system unrelated to Rails or Flask) and it's a mess.

For my current side-project, I'm actually building a thin ORM layer that basically handles migrations through hand-written SQL scripts.
And they say nerds don't grok design.

There's two sides to the argument. On the one hand, centralizing is big. It allows huge gains in efficiency- steam plants fueled by coal are 99% efficient, and by the time the power reaches the wheels of your car you're still probably around 60-80% (Otto cycle is 25% at absolute best, not counting drivetrain losses) It allows flexibility in source- nuclear, coal, wind, solar- and the source can be 'hot-swapped'.

At the same time, it is important to remember the energy has to come from somewhere, and this is something politicians, media, and industry has made a habit of carefully ignoring, so it does seem like a good idea to remind less inquisitive folks electric cars are not powered by free, unlimited energy. (Crazy as it may sound, folks believed that was the case for anything driven by 'renewable energy' a handful of years ago. That's what they were taught; renewable = free/unlimited)

No problem, Kenji :)
Sorry, I meant to write a different company name and product name for a company with one product, rather than brands.

Better phrased, my question should have been "Should a startup with one product, and no near future plans to add another, use the same name for the company and product?"
You didn't really say anything so I attempted to infer from context. My apologies if I did not infer correctly.
What does the title even mean? Doesn't seem like the article explains it either, or what the rationale for this bold statement is. It's basically "Women take less risks so they are better" all over again. Which is very debatable.

I want to love electric cars, but I see two big issues: (1) if they go mass market, all that electricity will still have to be generated somewhere. Coal? Nuclear? (2) The batteries need rare-earth minerals, which are brought to market through environmentally-degrading open pit mining. Furthermore, at this point, most rare-earths are available almost exclusively from China.

We are primarily B2B/Enterprise too, so that is very relevant. So your plan is to have lots of products, uniquely named, all under the Fogbeam Labs umbrella?

How would your strategy change if you only planned to have one product in the next few years?

A couple of companies from our industry are good examples here:

http://newrelic.com/ - Company name and single product name are both the same.

http://www.3tera.com/AppLogic/ - Company name and product name different (ignore their acquisition by CA for this example).

To me, 3tera's AppLogic sounds more suitable for B2B than New Relic. It also leaves us open to producing other products in the future, should we wish to.

One thing that really impressed me is that they didn't try to reinvent the wheel with their contracts. Good examples are the $PORT environment variable and sending all logs to stdout. It takes design maturity to do the wise thing instead of the fun thing, which would have been to force everyone to conform to a "Heroku Contract" API of some sort, which would really be no contract at all.

Did you investigate requesting the files directly from the filesystem, like "file:///home/monkey/.js/google.com.js".

You'd need to tell users to enable file access for the extension though chrome://extensions/, since that isn't enabled by default and users have to opt into it. I also don't know if there is a way to get the current user's homedir without hardcoding it.

Also: you're being super careful to not allow arbitrary reading of the filesystem, right? A good sanity check would be to ensure that realpath() of any file served is under ~/.js before handing it off.
