Block device based replication for Postgres seems a bit unconventional given that Postgres has native synchronous replication support with WAL streaming. Intuition tells me that you might get better performance if you let the DB itself do t

Can you elaborate on that? I haven't been able to conclude that from what it says on the pricing page [1]: > Data transfer is free. AWS does not charge for data transfer from your data producers to Amazon Kinesis Data Streams, or fr

Further, the Android app doesn't have an issue tracker. According to [1] and links in there it was removed without explanation. [1] https://github.com/telegramdesktop/tdesktop/issues/1137

That is wrong. If you read the thread, you would immediately see that, as I give examples there of how issues that were in the middle of being tested by users were closed, and that were acknowledged as real issues by the developers days bef

Tests and CI help you make sure that functionality actually works, that buttons you press have the desired effect, and that if I as a contributor ship you a pull request for a UX/feature improvement, both your and me can check that it

One argument might be "because Signal * has (almost) no tests, * has no CI (at least I could find none), * lacks some basic features competitors have, * sometimes doesn't ring when you call, and * they just closed all 1100 open is

Blogger even blocks the "Go back one page" (Alt+Left / mouse side button) for me. Visitor, you better stay.

shutdown() and half-closes are not "archaic" features. You need them to get even the basic stuff right (see https://blog.netherlabs.nl/articles/2009/01/18/the-ultimate-... ) and you need it even

Usually you need "nameserver 8.8.8.8", not just the IP. Or is a plain IP accepted as well?

Interesting article. > Your browser is usually clever enough to use the working IP address if the other one is not working. I found this to not work well. Have you tested it? For me it took 1-2 minutes for Chromium to switch over to the

How do you know that? Look how much Redox has achieved in so little time and with so few people. It has everything from a kernel to a fully working desktop GUI. All because they use a good language that allows easy code reuse and proper lib

In practice, it is an acceptable (as in, not great, but sufficient) solution. It is annoying to not have the high quality of IDE tooling you'd enjoy with Java, but in contrast to Java you can be very productive in Haskell even withou

Why would iperf-created traffic not be a good indicator of real world performance? On pretty much all sensible networks I've tested iperf3 on, performance of actual applications sending data was close to its results.

Overhead over what, and at which line speed? 1 Gbit/s, 10 Gbit/s? Tinc on bare metal hardware has pretty low CPU usage at 1 Gbit/s, but not so at 10 Gbit/s.

I think much worse is forgetting to check the size returned by a read() or write() call, especially when dealing with sockets. Unchecked malloc() crashes very easily, data chopped off in the middle usually triggers problems on the /oth

This sounds incredibly bad. For most more complex programs and libraries, you have no control over when they malloc(). If you spawn a thread and run any library function in it, it may malloc(). Doesn't this mean that any program writte

I don't get it, isn't this from 2013? It also says 2013 in the paper. And papers from 2013 cite this paper according to Google scholar. And I'm relatively sure I read this paper years ago.

Something is broken with the scrolling on that page. If I press arrow-down or page-down, nothing happens. It just shows "toot toot", not a great experience. Only after 20 seconds I figured that clicking the page and then the butto

I am currently using Stolon with synchronous replication for a setup, and overall it's great. It gives me automated failover, and -- perhaps more imporatantly -- the opportunity to exercise it a lot: I can reboot single servers willy-n

On the other hand: With hosted Postgres, when a failure does happen, isn't it much harder to get at the log files? They seem extremely useful to diagnose the problem and make sure it doesn't happen again, as the article shows. Wha
