Just a warning for everyone from California, Colorado, Washington, Oregon, etc. They do require you to certify for the background screening that you have not done any federally illegal drugs in the last 12 months, and possibly do drug tests

Back in 2005-2006 we ran into significant issues with the GC and pinned memory related to Windows sockets when building a networked server for XMPP. I believe the GC has improved since then for that scenario, but it was a big surprise when

This is why DevOps became a thing. It's complicated managing systems at scale. If you were using these tools and aren't at scale, well, that sucks. Unplanned downtime is the main drawback to both hosting your own OS's and usi

Interesting anecdote. As a father I feel nearly the exact opposite so I'll share my opinion. On academics, I want my kids to learn how to learn. And to love to learn. I want them to learn to be persistent, have mental fortitude, be for

If you are a software developer, the risk of committing to one year (three months at least partially in Mountain View) doesn't sound that scary to me. If you leave on good terms with your current employer you could probably just get yo

Separating things into components is great, at least in-process where you can enforce interfaces with compilers. Managing deployment, versioning, and compatibility of 10's of networked services (aka micro services) is not a good way to

I would say that you should be very careful with putting your Twitter-gained engineering knowledge to use in a startup. In most cases as a startup you should purposely not do many of the things Twitter does. For instance, micro services and

Most of the time IT is just implementing policy from the CIO, which is basing it on the requirements of the company's insurers. Insurance companies require some very annoying things like Anti-virus. It's like having a lock on your

I'm pretty sure I could never get an engineering job at companies that interview like this. I've shipped tons of real world products over the last 20 years, founded companies, and just reading about what it is like to interview sc

Looks like this uses a Ruby version of redlock under the hood: http://redis.io/topics/distlock Seems to be just a little abstraction so you don't manage the locks yourself.

So this is for read through caching with distributed locking. There are a couple scenarios where this is interesting. 1) If calculating the item in the cache is so expensive to some system, and might happen so many times concurrently, that

Perhaps I'm just feeling like a Grump Old Guy today itching for some down votes, but, why was concurrency control like this not in the client in the first place? Seems like a pretty core thing to an application designed to do destructi

Stored procedures, functions, triggers, etc, are very useful tools. They are used regularly in Microsoft SQL Server and Oracle systems. But, one has to be very careful to use them when warranted. The out-of-the-box tooling for debugging, ma

Irrigation methods can significantly reduce water usage for some crops. Others require gobs of water. I don't know the numbers for each crop, though. The Almond Board of California has some info on this for Almonds. Obviously, take thi

Yes, California's historical (lack of) ground water regulation and tracking was/is disturbing. Nobody has any idea how much is there or how much we are actually using. There are limits on extraction going into effect [0], but it m

% of GDP is one lens to look through when thinking about water rights. Having access to affordable/local/healthy food is another. I think incentives would help, yes. There is also a "use it or lose it" system builtin to

I know this is all straw man, but interesting stuff... Many crops use much more water than Almonds [0], I guess they're just fun to pick on. It'd be interesting to see a calorie/water comparison of many foods. Also, my family

by jconley 12y ago
It's much more convoluted than that, unfortunately. There are many layers of rights to water. Farmers will get anywhere from 100% to 0% of water from government sources. For instance, my family's farm is getting 0, so they are for

Many farmers are getting no [0] water this year and are relying on ground water to keep trees alive or not planting seasonal crops. Others get a very small fraction of their typical allotment [1]. California water rights are complicated...
