If you use the default mode MDB_SYNC then it's reliable but can be slow for writes. For max write performance you need MDB_NOSYNC (IIRC that's what the official benchmarks use) but then the whole database can be unrecoverable in c

So each enclosure hosts its own RAIDZ2. Have you tested if it can survive loss of USB connectivity? It can happen because of cable damage or movement, and also because of any failure in the enclosure's electronics.

What is the systemd equivalent for `service crond stop` and later `service crond start`? In other words, I want to disable all jobs for some time (for benchmarking) and then bring them back up.

Who are the phone/tablet manufacturers that are friendliest to rooting or installing open-source Android clones? It's a pain to do that on my Samsung Galaxy devices... I'm looking to buy a (new) 10'' tablet for that

> bloat their io buffer size to several GiB, set the eviction priority to 1 How do you tweak these? I'm aware of dirty_writeback_centisecs and the likes, but you are most likely referring to something different.

JGit has advanced a lot, and is in use in software handling huge repositories like Gerrit code review system. Java has also had numerous advancements in the past 10 years. It would be interesting to measure git vs JGit performance today. It

The main complaint still stands: the report provides very few details about the incomes and expenses. Out of almost 100 slides, I only see one, titled "Financial Disclosures". And it does not contain many disclosures.

Their financial report appears to be quite opaque and closed, as opposed to the Linux project and community.

Now that SSDs are ubiquitous, hard disk drive manufacturers should up their game: * 5.25'' drive which is taller (more platters) and wider (more sectors per platter) * Slow rotational speed to reduce consumption and vibrati

I find this article hard to read. But I believe its point stands. In Rust: - You bubble up errors using `?` operator, - then you get a nice error message. - However the location of the error is lost, the more complex the program, th

I had implemented it once in 2 lines of Python. some 25 years ago. If I can shake the rust maybe I'll be able to rederive it. Please do! I would love to see a concise and readable implementation in Python.

Thanks for the link to OPAQUE. It looks indeed much better than SCRAM-SHA, I like how the draft underlines that "clients never disclose their password to the server, even during registration." Do you know if/when it is consid

I would personally want to see the opposite: disable PLAIN or LOGIN or HTTP basic auth methods or plaintext HTML password-entry forms, and never ever send a password without a digest challenge-response method, even over TLS . Of course fir

Agreed for the read workloads, I have the same experience. It was designed primarily for an LDAP directory after all, an application that is very read-heavy.
