A lot of companies stop issuing stock options when they get to a certain size. Part of the thinking is that the company is now a "safe bet" so there's no need to give employees a potentially large upside in exchange for stayi

"it's not supposed to be dependent on subsidies to operate." I don't think this reflects the current thinking in Washington about Amtrak. I wasn't able to find its P/L history, but has it ever made a profit?

You should consider a keyboard with Cherry Clear switches or similar. Brown and blue have a relatively short travel distance, and it sounds like you are a heavy typer.

The US highway system did pay for itself out of gas taxes. The highway trust fund was set up for this purpose. See https://en.wikipedia.org/wiki/Highway_Trust_Fund . In recent years the highway trust fund has not be

Yes, you can run a single OS native process in KRaft mode, without using Docker. Docker just avoids the need to install a JVM, but it is not required.

I personally think Kafka has the edge in many ways. It will soon be possible to run a single-process Kafka cluster, which will unlock a lot of applications that previously people used an older systems for, simply because it was easier than

Part of the reason we are removing Kafka's ZooKeeper dependency is to get rid of that "heaviness." Going forward, you will no longer need to configure and run a separate ZooKeeper service just to run Kafka. For proof-of-conc

Even mathematicians are not all-knowing. There are lots of theorems that we suspect to be true that have never been proven to be true. In fact, Godel's incompleteness theorems state that there will always be statements that are true,

But I think Pulsar only stores server names and basic config info on ZK ( https://pulsar.apache.org/docs/en/administration-zk-bk/ ), which is much more managable. Unfortunately, this is not correct. BookKe

The harsh reality is that most software, no matter whether it's open source or closed, never makes it big. Take a stroll through an app store on iPhone-- or better yet, on Android! just to see how many apps there. You'll find hu

Lambdas in Java aren't really that complicated. If you understand anonymous classes, you understand lambdas. That article just compares Java's closures with Javascript's closures. The "limitation" is that Java&#x2

Hue is a Cloudera project, not even an Apache project. Sentry is an Apache project but primarily developed by Cloudera.

I think people often overestimate how smart the compiler is. DJB had a slide deck about this: http://cr.yp.to/talks/2015.04.16/slides-djb-20150416-a4.pdf Compilers are really useful... but, if it really has to b

The main industrial solvent described in superfund sites in the south bay is TCE (trichloroethelyine), which does not bioaccumulate. The fruit won't contain it, even if you live right on the superfund site. I'm not aware of a maj

Good to see that three decades later, C++ still has a massive inferiority complex about its older brother, C.

The question assumes that there is a single "proper" way to code in C++ that everyone agrees on. But that's just not the case. For example, Google bans exceptions, operator overloading, and most uses of Boost in their C++ c

Yes, you did it right. The parent comment was unfortunately incorrect. To me this is an absolute non-issue. Even if the research is free of bias and error (debatable), it's a tiny chance of cancer late in life. Spend your time worry

That is a fair point. In the United States, people used to make "apple jack" out of apple cider that way. It's essentially freeze distillation. But be warned! Don't do this, because it concentrates the methanol and ot

Despite what Fermentis claims, I don't think S-04 is that "traditional." It's a beast of a yeast and it will keep going and going. 10% is pushing the upper end of its range, but more because of the limited alcohol tole

Unfortunately, this is not a very realistic analysis. Martin mentions HDFS in the first paragraph as an example. But HDFS does not use partitions or consistent hashing for data assignment. All replicas in HDFS are placed manually accordin

PDF is the preferred format for reading textbooks and journal articles on e-readers. With a large-size e-reader it works well. The only real competitor to PDF is DjVu.
