Online Image Dimension & Size Finder from URL | MyFreeOnlineTools

Posted by jpluimers on 2022/11/10

This was the only site I could find that can you can enter a URL and get the image dimensions.

[Wayback/Archive.is] Onlie Image Dimension & Size Finder from URL | MyFreeOnlineTools

Yes, you can use web-browser tools for this, but the responsive web usually gives you the wrong size.

And yes, it should be “Online”, not “Onlie”, but I used the web-page title which already has the error.

Installing vscode extensions from within the Visual Studio Code terminal was way easier than I anticipated

Posted by jpluimers on 2022/11/09

Having missed quite a lot of Visual Studio Code releases during my metastasised rectum cancer treatment and recovery, it had become both very mature, but also very reliant of having the right extensions installed.

In that period, the extension marketplace grew remarkably, so I really wanted an easy way to install them from within the inside vscode integrated Windows Terminal.

A while ago I wrote How can you export the Visual Studio Code extension list? (via: Stack Overflow), which generated a small script with code --install-extension <extension-name> lines so I could executed those from the command-line for Visual Studio installations on new machines.

Boy was I surprised that you can just as well execute them from the [Wayback/Archive] Integrated Terminal in Visual Studio Code as well (:

When doing so, the Visual Studio Code instance around that Integrated Terminal will automatically pick up the new extension.

I found that with a [Wayback/Archive] vscode install extension from within visual studio code console – Google Search and bumping in the video also embedded below the signature: [Archive] VS Code tips — Installing extensions from the command line using –install-extension – YouTube.

The video also showed that the installation syntax can also include the version number like this:

UTC and ISO 8601, or GTFO

Posted by jpluimers on 2022/11/08

Always schedule your meetings in UTC, and use ISO-8601 date and time notation. Because time zone conversions are hard, especially with so many daylight saving time conventions.

I want not just a “UTC or GTFO” shirt, but a “UTC and ISO-8601, or GTFO” shirt.

It means I do not agree with [Archive.is] Colin Nederkoorn on Twitter: “Pro tip: Don’t schedule recurring meetings in UTC if you live in a place with daylight savings.… “ with multi-time zone teams: having it in UTC will balance out the DST changes over the teams.

Some more relevant Tweets that triggered me writing this post:

Stop using tail -f (mostly)

Posted by jpluimers on 2022/11/07

Some interesting bits from [WayBack] Stop using tail -f (mostly):

  • say you want to watch the file production.log:
    $ less +F production.log
    
    Important
    log
    information
    here
    
    Waiting for data... (interrupt to abort)

    Here you have pretty much the same behaviour you’d get with tail.

    Now let’s say something interesting appears, and you want to search all the occurrences of “foo”. You can just hit Ctrl-c to go to “normal” less mode (as if you had opened the file without the +F flag), and then you have all the normal less features you’d expect, including the search with /foo. You can go to the next or previous occurrence with n or N, up and down with j and k, create marks with m and do all sort of things that less(1) says you can do.

    Once you are done, just hit F to go back to watching mode again. It’s that easy.

  • When you need to watch multiple files at the same time, tail -f can actually give you a better output.

Related: [WayBack] shell – The ‘less’ command-line equivalent of ‘tail -f’ – Unix & Linux Stack Exchange

I prefer tail -F

-F – The -F option implies the -f option, but tail will also check to see if the file being followed has been renamed or rotated.

The less equivalent: less +F --follow-name

SQL comma bullet point formatting: because AS is optional

Posted by jpluimers on 2022/11/03

Do you see the error below?

(note: OCR via [Wayback/Archive.is] Best Free OCR API, Online OCR, Searchable PDF – Fresh 2021 OCR Software)

SELECT
  license date
  expiration_date,
  renewal_due_date
FROM license
WHERE expiration_date IS NULL
AND processing != 'Automatic'
AND edition != 'Other'
expiration_date renewal_ due date
1 2016-04-08 09:50:00 [NULL]
2 2013-11-14 11:15:00 [NULL]
3 2014-11-20 14:51:00 [NULL]
4 2017-07-21 16:00:00 [NULL]
5 2018-12-17 14:37:46 2020-12-17 14:37:46

All of the expiration_date columns have values, which is contrary to the WHERE clause. This is because the table itself contains an expiration_date column, and the SELECT part aliases license_date into expiration_date.

The result is that you see rows that have expiration_date being NULL, but license_date having a value.

So I totally agree with [Archive.is] Mathias Magnusson on Twitter: “That is one reason I’m a form believer in comma bullet point in my SQL. Problems like that has bit me far too often due to som issue with commas.… “

This is how the SQL should have looked:

SELECT
  license date
, expiration_date
, renewal_due_date
FROM license
WHERE expiration_date IS NULL
AND processing != 'Automatic'
AND edition != 'Other'

Yes indeed: an alias of a column without the AS keyword is allowed in quite a few SQL dialects (they differ even more widely in SQL extensions like SQL/PSM, T-SQL, PL/SQL, SQL_PL, or ABAB).

Aliases are for output, cannot be used in WHERE (but can in ORDER BY).

You can see what happens (and how hard this can become on one line) with these two dbfiddle queries running on Microsoft SQL Server 2019 dialect (though it works similar in other dialects):

  1. select a b, c from (values (9, 1, 2), (8, 3, 4), (7, 5, 6)) t(a, b, c) order by b
    I saved it as [Wayback/Archive.is] SQL Server 2019 | dbfiddle: select a b, c from (values (9, 1, 2), (8, 3, 4), (7, 5, 6)) t(a, b, c) order by b
    Resulting in

    b c
    7 6
    8 4
    9 2

    It shows only the column names a and b, but note the table itself is aliased to t above as well.

  2. select a, b, c from (values (9, 1, 2), (8, 3, 4), (7, 5, 6)) t(a, b, c) order by b
    I saved it as [Wayback/Archive.is] SQL Server 2019 | dbfiddle: select a, b, c from (values (9, 1, 2), (8, 3, 4), (7, 5, 6)) t(a, b, c) order by b
    Resulting in

    a b c
    9 1 2
    8 3 4
    7 5 6

    It shows only the column names a, b and c, but note the table itself is aliased to t above as well.

I really wish various SQL dialects would force the SQL syntax to be (together with a hint that the alias would overwrite an existing field):

SELECT
  license date AS expiration_date
, renewal_due_date
FROM license
WHERE expiration_date IS NULL
AND processing != 'Automatic'
AND edition != 'Other'

That is not going to happen, so the second best is to wish for tooling to hint/warn about it, and provide better syntax highlighting for it. That seems work in progress by now:
