Yep. I waste an hour (probably) every week unsubscribing from various newsletters and marketing campaigns that I don't care about. Most corporations have largely taken "this person has given me an email address" -- even if on

FreeNAS gets fairly close to this out of the box. My home server runs ZFS with RAIDZ2. By default, I think, there's a weekly cronjob to scrub the ZFS pool (integrity check everything, as I understand it), and then the results of that s

This is how it's defined in FIPS-180, more or less (SHA-224 is SHA-256/224). This confusion is why I like explicitly stating SHA-256/x or SHA-512/x.

His idea is correct -- you're right, you don't know the entire internal state. But you can generate 2^32 possible internal states (because there are 32 bits of missing information), then perform the length extension process using

Actions that require database downtime/restarts can happen during the maintenance window. For example, if you change a DB parameter that requires a database restart, you can tell AWS to restart the DB during the next maintenance window

That doesn't mean they're unavailable for 20 minutes weekly, probably because of the nature of AWS's multi-AZ RDS setup. At our shop, we haven't had any problems with RDS maintenance at all -- and we would indeed get pag

At my workplace, we've started using jOOQ for this sort of thing. https://www.jooq.org/ (albeit we're a Java shop, not a C# shop) It still sort of generates SQL for you, but really you end up writing the SQL yours

Having a CC number canceled and a new one issued can be a hassle. That's why I still want my CC info to be kept secret and safe. I'm not really worried about CC fraud otherwise.

Agreed. The section basically boils down to "despite maybe looking simpler, Single-Decree Paxos is still tricky." I don't think something particular and formal like Kolmogorov complexity even fits the tone there.

The article abuses Kolmogorov complexity... > When it is applied to the algorithms, it means that an algorithm with the shortest implementation is simpler. That is misleading. Kolmogorov complexity is the length of the shortest program (

In practice, the chance of a digest collision between two messages that differ in a single bit is exceedingly small for any secure cryptographic hash function. It's so small that it's practically not worth considering. Cryptograph

I don't personally run a fanless build... I use the design I mentioned at the end of my post, liquid cooling with almost silent fans (Noctua brand, like you linked). The defining feature of a fanless build really is cost. It's har

Yep. :-) The heatsinks for fanless designs are enormous, but the result (no moving parts in your PC, if you eschew hard drive(s) as well) is really neat in my opinion, and great if you do audio work - as my roommate does. Totally silent,
