I've seen some disgusting Java and C++, but that company had pretty high engineering standards so the Java and C++ was always good. The Python was _supposed_ to be good, too, but 20+ devs making changes to this one config generator scr

So there's the same situation as with TS where you can't do runtime reflection to get type annotations? That seems frustrating. The one really rough edge I've seen in TS is type guards. Not the end of the world, obviously, bu

The worst, buggiest, least maintainable code I've ever dealt with was a 500ish line (heavily tested!) untyped Python file at my last job. Caused more trouble than all the Java and C++ and Go combined. My personal experience with compil

It refers to "changelist". Google uses a Perforce-like VCS internally, and they kept the Perforce terminology: https://www.perforce.com/perforce/doc.051/manuals/p4guide/07...

There's plenty you can say if you have a clearance that won't get you sent to jail -- pretty much anything that doesn't state a classified fact or allow one to be inferred. "Every mission I worked on got people killed ne

It's ironic that this was posted on the same day as the NYT reports a US intel success that has substantively advanced American foreign policy objectives and possibly saved lives: https://www.nytimes.com/2019/08&#x

There's lots of stuff where we trust that expert communities are being honest. Medical research is impossible to verify unless you get access to the raw data (get into a PhD program and get a grant and then get a DUA... all in all, pos

Good intel is no substitute for good judgement. But no or bad intel seriously impairs the ability to exercise good judgement. Pointing out stories (the same handful that have been repeated over and over before -- MK Ultra, Cambridge 5, Ames

There's also a strong bias to remember/talk about the cases that turned out poorly, not the ones that turn out well. "CIA bungles [thing]" is a splashy headline and memorable story. "US does 10% better in trade nego

At least in the US, trying to ride a bike outdoors in a lot of places is a good way to get yourself killed by a car. I've spent the last 5 years in NYC and SF (which are both very bike friendly). I bike rarely and pretty cautiously, bu

No one (in America) ever builds public transit without demand for it. And even when there is demand for it, it's a struggle. So you have to get rid of the parking first.

Here's a benchmark of KStreams and Flink [1]. Note that the Flink vs Spark comparison is disputed [2], but both Flink and Spark are several orders of magnitude faster than KStreams. This is inevitable given KStreams architecture -- it

According to my parents (who were actually alive then), there was a backlash against more traditional educational approaches (particularly anything involving memorization) in the '60s. Education reoriented towards teaching students to

Yup! And that sane approach (look at the letters that make up the word, and speak the word out loud) is phonics.

I ultimately agreed with her based on reading about the research, which is at this point 30+ years old -- and popularized 20+ years ago.

by jdm2212 7y ago
This was my experience also. My mom taught me phonics at home, while my peers learned whole language at school. And (quite possibly as a result) I was reading much longer books at a much earlier age than my peers.

Anecdata: As long as I knew her, my ex had the difficulties described in the article. She blamed how she was taught to read in school -- specifically not having been taught phonics. I figured that was nonsense, and blamed a peculiar-to-her

The only two of those I know are Kafka and Flink. For those two: Flink is much more full-featured and performant (basically the full Google DataFlow API, and several orders of magnitude faster than Kafka Streaming), but Kafka Streaming has

This is exciting! I've been using Flink a lot lately, and fine-grained recovery is going to be very useful for [work stuff]!

The American political spectrum is way bigger than the political spectrum in most European countries. There's a lot more potential for deep disagreement in the US when people talk politics.

I don't want to discourage doing that (I've been using those for ~10 years and love them), but please be very careful getting ramped up with thin-soled shoes. They tend to put a lot of strain on your calves and ankles if you aren&

The claim is that you can't do it consistently. Your sentiment detector has to more accurately capture the state of a randomly selected set of companies (not one selected with the benefit of hindsight, like Enron) based on news sentime

With lions, there's something similar IIRC. Once they realize how easy humans are to kill, they won't eat anything else.

Often, our intel has hacked their intel and watched them do it. For example: the US is certain that North Korea was behind the Sony hack because South Korean intelligence hacked North Korean intelligence, and the NSA hacked South Korean int

The article is pretty clear that on the small unit and soldier level the Arab forces are less effective, too. Specialists horde information, soldiers don't train for multiple roles, junior officers mistreat their soldiers, no one shows

There's more commonalities than just "dictatorship". Saudi Arabia, Iraq, Jordan and Syria are all made up of multiple competing groups (tribes, religious sects, etc.) and the dictator is carrying out a delicate balancing act

To paraphrase Keynes: as time (t) => infinity, we're all dead. We don't live our lives in a society at the end of the long run, we live our lives in a society that exists here and now. Social mobility might end up at zero in a
