Eh? Calling system() for a binary without a path? And why system() using execl() in the first place, when you could do something using execve() without a sh inbetween instead?

Even w/o an exploit this can be prettier and more secure.

It is Sun ZFS.

And there are many interesting stops between FFS/UFS and ZFS. And ZFS, even today, is not the best system to use in all scenarios, by some margin.

"We" don't. "We" need to create individual accounts for each eligible staff member and provide each with a 2FA system, for example a Fido key or a TOTP auth app, or an app that uses push notifications and asks for a "yes".

If you booked with Booking, and the hotel called you back, and told you they don't use Booking any more, how do you imagine did they get the information needed to call you back and knew of the booking?

What you have here is commission fraud on behalf of the hotel against Booking.com, and if you call back Booking.com and tell them about it, they will set the hotel straight.

Or you get back to the hotel, tell them you understand how commission fraud works and if they are willing to split that commission (18%) half and half with you.

Originally the question was "What is Honeycomb.io and Opentracing doing and how can I get this into my existing application?" on IRC. On explaining, the discussion went into various directions (Fred Fish C Debugging Macros and tracing Python).

I just pushed an addendum, and it is being rendered right now.

Rachel's Site shows an Apache 2.4 banner.

Apache has a little known module as part of the build, at least in Ubuntu: mod_md.

Use this, it is trivial to set up, and completely automated the Let's Encrypt workflow and renewal, no external stuff necessary. It is as simple as adding a few lines to the global config, remove almost all SSL config and restarting the server (twice).

Anything that is shipped on Android, on iOS, or as a macOS app, apparently. Sqlite is incredibly useful and much more prevalent that you imagine.

If, in a customer facing database, you have to table scan, you have already lost.

For data warehouses this is a different story, but god help you if you are table scanning in OLTP context.

There are collation changes between utf8 and utf8mb4. Specifically, utf8mb4 uses the (much better) UCA 9.0 algorithm.

But this implies that all indexes will have to be regenerated, if they contain a column that is utf8 and will be converted. As they sort differently, this requires rebuilding the index from scratch. Depending on data size this can take measurable time and effort.

ONLY_FULL_GROUP_BY is the default in MySQL since 5.7.5.

Back then MySQL used the memory engine for implicit temporary tables, and memory engine has no variable width data types. So a "varchar" becomes a "char", and a "varchar(255) charset utf8" becomes an allocation of six times 255 = 1530 bytes (filled with a lot of padding).

Reducing this to 3 bytes is still bad, but only half as bad as before.

Only MySQL 8 introduced innodb typed temporary tables (unlogged, even), so with MySQL 8 this is no longer a problem.

The point of TCP is to provide protection against packet loss and reordering, and to provide flow control.

You should be running flash with self-encryption (and make sure you have a drive that implements that correctly).

To zap a drive you ask it to securely drop the self-encryption key. The data will still be there, but without the key it is indistinguishable from random noise.
