Just recently picked up a Lenovo Thinkpad and immediately installed Ubuntu 14.04 LTS on it. It's quite unfortunate that the bar is set so low with Linux laptops that the thing I enjoyed most is that everything worked out of the box, in

Interesting. I was checking out FDB earlier this month for solving some interesting scalability challenges. I'm quite glad I hadn't decided to re-architect a bunch things based on it! Did any of you get bitten?

Can anybody elaborate on the destruction of coins? Sounds dangerous... "If the validator causes the blockchain to fork while its coins are locked in bond, all of its coins are destroyed. This means that as long as you sync your blockch

How do you determine if your tree is pathological? I.e., what types of tree structures would you find the closure table model to be pathological enough to warrant other modeling options?

Genuinely curious, are there any cases of production Go environments where routing is the bottleneck of their HTTP services? I'd think any kind of data access in the service would be the bottleneck, not routing.

I believe there was controversy in the FOSS community over Microsoft's patent application for the concept: https://www.google.com/patents/US8255828 I'd speculate that this patent application provided at least

Would really be great to show some examples of the beautiful documents that can be created right up-front. I assume that's a big selling point because nobody wants ugly documents. So, I'd take the time and display examples front a

You should let it run idle and see how long until the battery is depleted. I underestimated the losses due to efficiency with my Libretto project (boost converters run at different efficiencies depending on the power draw). I was able to ge

Indeed! But, a broken one does not :)

Very cool and inspiring. I'm doing something similar [1] by replacing the guts of a Toshiba Libretto 50C (a tiny laptop from 1996) with a Raspberry Pi and upgrading its screen to a 7" widescreen. It's slightly larger than y

I agree. "Finish something today" is not an excuse to avoid medium and long-term goal setting and defining tasks that need to be accomplished to move forward.

Similar comments from a University of Texas, Austin commencement speech by Adm. McRaven [1]: "Every morning in basic SEAL training, my instructors, who at the time were all Vietnam veterans, would show up in my barracks room and the fi

It is usually set to a fixed number of users per hour with a minimum wait time. Keeps the server happy when I get HN'd/Reddit'd/etc. (Does anybody get Slashdotted anymore?)

by jsherer 12y ago
Thanks. I've signed up for a couple of services that do that. It seems to work out even though some people get a little annoyed that they have to wait.

Closer to 50/50. 50% of the servers do actual tedious work. 50% cater to users' needs.

Thanks. Selling a web service to consumers in a market where the previous leader was free is tough. But, it's doable. Shoot me an email (email in profile) if you want to talk specifics.

Most of the servers are workers which fetch feeds. Parallel downloads across a number of low-level commodity servers. Additionally, there's a master and slave Postgres database, a small Cassandra cluster, 2 redis boxes, an elasticsearc

Not overkill as servers are not equal and different apps require different infrastructure. The bulk of my servers are small worker servers that go out and fetch feeds. Parallel downloads, high network throughput, low CPU/memory.

I run Minimal Reader [1] (which has about 5k users) and I can say that running a web app like this takes a lot of time and energy keeping everything running smoothly. My service has a lot of moving parts, all of which are distributed among

I'm curious, as the document doesn't mention it, what is the benefit of bootstrapping? Is it primarily to allow future development to happen in the bootstrapped language, instead of the lower-level language (C in this case)? Or is

I was digging on this a little deeper and found this discussion from 2011 [1] that has some interesting points. [1]: https://groups.google.com/forum/#!topic/nosql-databases/4Aco...

Like the post says, this seems to be similar to Google's Chubby system, and ZooKeeper for locks/leases. Are there modifications to this process for those systems to help with safety, or do they also have the same problem?

I love the simplicity of this, especially if you're already using Cassandra. Is anybody out there using a lease mechanism like this (i.e., atop Cassandra) in production? Are there any pitfalls or edge cases in taking this approach?

Is there a system you would prefer that would better "represent the will of the people"?
