I just fought through all the various guides and outdated suggestions, and lots of AI generated garbage using non-existent commands, to come up with this script. Now you won’t have to. If you’re struggling with your own script and don’t want to throw it all away and adapt (adopt?) this one, the key takeaways are […]
If the Antimalware Service Executable or the Windows Defender Advanced Threat Protection Service Executable is constantly hogging your CPU while you’re trying to get work done, or draining the battery of your laptop, you’re likely constantly changing files it deems necessary to scan. On my work machine, I had two culprits: A virtual machine disk […]
Quick note to self, when making a complicated query, comparing to data in a subquery, the postgres query planner will sometimes decide to perform the entire outer query without the comparison, cache the results, and then run the inner query. Example: SELECT DISTINCT …FROM …INNER JOIN … ON …WHERE … AND … AND …id IN […]
Archiving some documentation for the Norwegian microcomputer TIKI-100 here, in case anyone needs it. I’ve sold mine, but Tommy Ovesen of Arctic Retro has graciously scanned the manuals I had for them. They’re here as well, for redundancy: User Manual – Instruksjonsbok TIKOS User/Technical Manual – TIKOS Bruker- og teknisk manual Software Catalog – Programvarekatalog […]
NOTE: In applications targeting net7.0+, Microsoft has fixed this issue, and you can set your Object to be default null (MyClass thingamagic= null), having it work as expected.Leaving the below hack in here for anyone stuck on net6 or below. — You may be here because you’re getting this: {“type”:”https://tools.ietf.org/html/rfc7231#section-6.5.13″,”title”:”Unsupported Media Type”,”status”:415,”traceId”:”00-0d785f3d1cb4fd71bc36ee25561e4b48-6bc5df1f0d070024-00″} Or this: {“type”:”https://tools.ietf.org/html/rfc7231#section-6.5.1″,”title”:”One […]
If you have pivoted data, you probably don’t want to name all the columns to move one, as a lot of them are going to contain dynamic data. The solution is to use the list of columns, manually moving the one you want into the desired position, as such: = Table.ReorderColumns(PreviousStepName, List.InsertRange(List.RemoveItems(Table.ColumnNames(PreviousStepName), {“ColumnToMove”}), 4, {“ColumnToMove”})) […]
We recently had a need to unpivot two columns with item id’s in them so they’d come out as a single column with distinct values. Some of the entries had <null> as the parent id, and null should not appear in the output. One could solve this with a simple UNION, but the view we […]
Recursive SQL queries. They’re hard to read, and even harder to wrap your head around. They’re handy when you have a self-referencing table (intermediates allowed, but complicates things) that somehow represents a tree, such as the management tree of a corporation, where each user has a manager_id that’s also a user_id in itself. There’s a […]
The correct way to copy data is not to extract to a CSV and import with some tool, to manually create INSERT queries, or to try filtering the pg_dump output. You should use the COPY function included in postgres, as such: psql -c “COPY (SELECT * FROM my_table WHERE created_at > ‘2012-05-01’) TO STDOUT;” source_db […]
So, you’re struggling with your IAM role login? psql: error: FATAL: password authentication failed for user “mydbuser”psql: error: FATAL: PAM authentication failed for user “mydbuser” This list is specifically for PostgreSQL, accessed by ECS containers and developers, but most of it would apply to any IAM compatible setup. First, check that you have allowed IAM […]
