Autodesk is the Oracle of the professional media world.

Adobe is their Microsoft.

I hear this criticism a lot, but it's simply not true. What doesn't help is what people mean by "photos" or "photo editing".

RAW Photo import and editing is currently limited in Krita, and you cannot export RAW formats. But even professionals tend not to use destructive layer based editors like gimp/krita/photoshop/painter/paintshop pro etc and are instead using dedicated software like lightroom, rawtherapee and darkroom.

But if your output format is not RAW, then you have more than enough to edit "photos".

You have layers, masking, vectors and spatial bitmap editors. That's all any of these editors workflows have been since the 90's. Anything else is extra.

Put me in front of Photoshop on modern mac or IFX Amazon Paint on Irix and my workflow and (sloppy) output would be the same.

mathnode··on Updating a 50 terabyte PostgreSQL database (2018)
MariaDB has offered online schema changes in InnoDB for several years now with continous improvement.

Their (currently commercial only) engine, Xpand (previously known as Clustrix), offers distributed SQL as well as online schema changes.

No need for an unncessary database migration if you are already on LAMP and the like to get these fancy features. However handling any kind of change should be handled with care, especially on such a large dataset. Test your rollback procedures!

Disclaimer, I work for MariaDB.

mathnode··on AWS announces forks of Elasticsearch and Kibana
MariaDB came out with the BSL license for projects like maxcale to help protect against AWS nonsense (and the like). The mysql -> mariadb response is completely different, but no less terrible.

This is history repeating itself as Amazon, once again, attempt to gut open source efforts.

For a short while Amazon did contribute to some MariaDB projects.

MongoDB now have similar license and AWS offers compatible API's.

I've ordered one, it arrives tomorrow, and until I read your comment I had overlooked the book.

When I was younger, I was lucky enough to have an Amiga Commodore 500+, and I read all the included literature cover to cover, over and over again. I have a lot to thank those manuals for!

EDIT: It's available for free online as a PDF, https://magpi.raspberrypi.org/books/beginners-guide-4th-ed

If you are using Mariabackup or a volume snapshot, then you retain the history.
mathnode··on Ask HN: My wife might lose the ability to speak in 3 weeks – how to prepare?
If you don’t have any children (yet) you should get her to record herself reading some of her favourite children’s books. At the very least she will be able to read along with them. Children’s books are quite sparse, so a page per-track is easy to do.
mathnode··on Jepsen: MongoDB 4.2.6
No, but it does support online DDL for some operations in InnoDB.

Very few database systems support online DDL, which unlike a transaction, does not require undo or rollback resources. Of course one must have a rollback procedure if something fails, but you need one for transactions too, just in case.

An online rollback is far lest costly than a transactional rollback, because and online rollback is just undoing what you did. Added a column you didn't want in one query? Remove it again in another, very quickly.

TokuDB (a mysql/mariadb storage engine) supported all DDL as an online operation. But percona killed it in favour of TokuMX, the MongoDB equivalent.

TokuMX has no upgrade path to wired tiger, only one major customer at Percona (I can't say who it is) and no engineers.

Any kind of DDL is tricky and requires users to RTFM for the intricacies of their chosen database. One size rarely fits all.

15.1 is not a version. Since MariaDB 10.2, this is not possible as strict_trans_tables is enabled by default in sql_mode.
mathnode··on A first look at Unreal Engine 5
Epic Online Services; this is the big take away for UE5, graphics will always improve, but user experience is key to long term success.

We can now all sit back and watch Epic eat Valve’s and Microsoft’s Lunch right in front of them, like some kind of sordid picnic.

I look forward to seeing the pricing details and revenue options based on player base and time.

It's a lovely article; in substance and style. I purchased a very cheap (£50) win10 tablet a few years ago, and content like this makes me very happy.
mathnode··on OLPC’s $100 laptop was going to change the world (2018)
Not at all, it was a rather funky radial menu.

I have no idea why it wasn't just a customised version of something like xfce, lxqt and what have you.

As a pico8 user myself, I love the the tweetcarts:

Some amazing stuff.

I have never heard of this (UK), a bar of soap you can wash hair with?

Do we know if he or the other oculus team members are still using racket?

For desktops Libreoffice Base is nice.

For web hosting, I would push PHP. Each page is it's own end point!

Does anyone know if FoundationDB is gaining ground over Cassandra at Apple?

mathnode··on REXPaint: Powerful, User-Friendly ASCII Art Editor
It looks very impressive, in my moment of ignorance however, I got excited that maybe the REX was referring to REXX. That would have been quite a feat.
mathnode··on Microsoft Sandboxes Windows Defender
Recently I linked to a press release for a software acquisition, but mine was marked as a dupe, and the blog link promoted.

I am not trying to get them sweet sweet up-votes. Just engage in my community.

Thanks everyone at golang.

mathnode··on Dungeons Tome – Tool for generating dungeons for RPGs
I like it. But what really impresses me is how fast the whole site is, even with a captcha.
mathnode··on Ask HN: Favorite note-taking software?
Apple Notes. I even use it for code on the go.
mathnode··on Query Parquet files in SQLite
If you have a database that supports SQLMED, you can probably already query outward table data without loading/serialising between formats. You can even optionally generate an index on some systems.

MariaDB has the Connect Engine, Postgres has Foreign Data Wrappers (fdw), define an openrowset for mssql using an odbc or ole driver and config. DB2 and informix have federated options.

The author has missed a lot of detail about the breadth of options the FDW for csv provides. Just like a normal table you should define column names and ideally their types so you don’t have just ordinal/generates column names (if there is no header line), which the author does anyway for SQLite. The same problem of denormalisation exists, in which case, data scrubbing cannot be avoided; yet more serialisation eating precious cycles and memory.

My point is, read the manual for your database, it might surprise you as to what it can already do, and how much time it can save you.

mathnode··on Star Citizen's ARK Starmap
I just now tried again and it works. Maybe it was just bandwidth or they fixed something. Both?
mathnode··on Star Citizen's ARK Starmap
On Edge and Safari it's just an interface over a black screen. For a video game to reach a wider audience, should this not be a little more compatible with us boring old vanilla users?

mathnode··on GrafX2 – a bitmap paint program inspired by Amiga programs
The best follow ups by far were Avid Matador and Discreet Combustion.

Avid bundled Matador (and FXTree) into Softimage, which Autodesk later absorbed and killed off.

Discreet were also assimilated by Autodesk, and Combustion was later killed.
