When your classmates are such lobotomites, that they manage to fry 11 fucking IC's within a day! And I am the one who has to find and replace all the broken stuff. FFS it says 9V right there on the board NOT 12V! No, your board should not draw 1.7AMPS! This chip is getting kinda hot. What is wrong? ONE OF YOUR FUCKING PROBES IS BRIDGING ONE OF THE PINS!
Why isnt this working correctly? You adjusted the wrong fucking potentiometer!
I know I have far more experience than most of my classmates, but man, atleast try to not break things by just thinking: "I dont know dis. (Its actually written in the docs!) So imma assume it will be fine if I do dis. It wasnt fine!"
Also IF something doesnt work, DO NOT TURN UP THE VOLTAGE ON THE CIRCUIT BECAUSE IT APPEARS TO BE THE CLOSEST POSSIBLE ERROR. Which in most cases it is not!

Today, for fun, I wrote prime number generation upto 1000 using pure single MySQL query.
No already created tables, no procedures, no variables. Just pure SQL using derived tables.
So does this mean that pure SQL statements do not have the halting problem?
Putting an EXPLAIN over the query I could see how MySQL guessed that the total number of calculations would be 1000*1000 even before executing the query in itself and this is amazing ♥️
I have attached a screenshot of the query and if you are curious, I have also left below the plain text.
PS this was a SQL problem in Hackerrank.
MySQL query:
select group_concat(primeNumber SEPARATOR '&') from
(select numberTable.number as primeNumber from
(select cast((concat(tens, units, hundreds)+1) as UNSIGNED) as number from
(select 0 as units union select 1 union select 2 union select 3 union select 4 union select 5 union select 6 union select 7 union select 8 union select 9) unitsTable,
(select 0 as tens union select 1 union select 2 union select 3 union select 4 union select 5 union select 6 union select 7 union select 8 union select 9) tensTable,
(select 0 as hundreds union select 1 union select 2 union select 3 union select 4 union select 5 union select 6 union select 7 union select 8 union select 9) hundredsTable order by number) numberTable
inner join
(select cast((concat(tens, units, hundreds)+1) as UNSIGNED) as divisor from
(select 0 as units union select 1 union select 2 union select 3 union select 4 union select 5 union select 6 union select 7 union select 8 union select 9) unitsTable,
(select 0 as tens union select 1 union select 2 union select 3 union select 4 union select 5 union select 6 union select 7 union select 8 union select 9) tensTable,
(select 0 as hundreds union select 1 union select 2 union select 3 union select 4 union select 5 union select 6 union select 7 union select 8 union select 9) hundredsTable order by divisor) divisorTable
on (divisorTable.divisor<=numberTable.number and divisorTable.divisor!=1)
where numberTable.number%divisorTable.divisor=0
group by numberTable.number having count(*)<=1 order by numberTable.number) resultTable;

And here comes the last part of my story so far.
After deploying the domain, configuring PCs, configuring the server, configuring the switch, installing software, checking that the correct settings have been applied, configuring MS Outlook (don't ask) and giving each and every user a d e t a i l e d tutorial on using the PC like a modern human and not as a Homo Erectus, I had to lock my door, put down my phone and disconnect the ship's announcement system's speaker in my room. The reasons?
- No one could use USB storage media, or any storage media. As per security policy I emailed and told them about.
- No one could use the ship's computers to connect to the internet. Again, as per policy.
- No one had any games on their Windows 10 Pro machines. As per policy.
- Everyone had to use a 10-character password, valid for 3 months, with certain restrictions. As per policy.
For reasons mentioned above, I had to (almost) blackmail the CO to draft an order enforcing those policies in writing (I know it's standard procedure for you, but for the military where I am it was a truly alien experience). Also, because I never trusted the users to actually backup their data locally, I had UrBackup clone their entire home folder, and a scheduled task execute a script storing them to the old online drive. Soon it became apparent why: (for every sysadmin this is routine, but this was my first experience)
- People kept deleting their files, whining to me to restore them
- People kept getting locked out because they kept entering their password WRONG for FIVE times IN a ROW because THEY had FORGOTTEN the CAPS lock KEY on. Had to enter three or four times during weekend for that.
- People kept whining about the no-USB policy, despite offering e-mail and shared folders.
The final straw was the updates. The CO insisted that I set the updates to manual because some PCs must not restart on their own. The problem is, some users barely ever checked. One particular user, when I asked him to check and do the updates, claimed he did that yesterday. Meanwhile, on the WSUS console: PC inactive for over 90 days.
I blocked the ship's phone when I got reassigned.
Phiew, finally I got all those off my chest! Thanks, guys. All of the rants so far remind me of one quote from Dave Barry:
