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;9 -
Ok, who among you crazy people came up with this idea? https://userinyerface.com
That website is the UX equivalent of murder 1. It took skill, planning and a very special brand of crazy to create.10 -
Hey,
I'm working on creating API for learnpress a plugin of wordpress.
I'm stuck at this type of data in database.
Can you tell me how to extract data from this type of string in php?
a:3:{s:4:"text";s:6:"Mobile";s:5:"value";s:27:"155938536720245cf2551731707";s:7:"is_true";s:3:"yes";}3 -

Navy story time again. Grab that coffee and fire up Kali, the theme is security.
So, when I got promoted to Lieutenant Jr. I had to attend a 1-year school inside my nostalgic Naval Academy... BUT! I was wiser, I was older... and I was bored. Like, really bored. What could go wrong? Well, all my fellow officers were bored too, so they started downloading/streaming/torrenting like crazy, and I had to wait for hours for the Kali updates to download, so...
mdk3 wlan0mon -d
I had this external wifi atheros card with two antennae and kicked all of them off the wifi. Some slightly smarter ones plugged cables on the net, and kept going, enjoying much faster speeds. I had to go to the bathroom, and once I returned they had unplugged the card. That kind of pissed me off, since they also thought it would be funny to hide it, along with the mouse.
But, oh boy, they had no idea what supreme asshole I can be when I am irked.
So, arpspoof it is. Turns out, there were no subnetworks, and the broadcast domain was ALL of the academy. That means I shut EVERYONE off, except me. Hardware was returned in 1 minute with the requested apologies, but fuck it, I kept the whole academy off the net for 6 hours. The sysadmin ran around like crazy, because nothing was working. Not even the servers.
I finally took pity on the guy (he had gotten the duties of sysadmin when the previous sysad died, so think about that) and he almost assaulted me when I told him. As it turned out, the guy never had any training or knowledge on security, so I had to show him a few things, and point him to where he could study about the rest. But still, some selective arp poison on select douchebags was in order...
Needless to say, people were VERY polite to me after that. And the net speed was up again, so I got bored. Again. So I started scanning the net.
To be continued...3 -
!dev !sex I promise this is a good read
I once read the whole bible.
Not in one sitting, ofc. I read it in a period of a year, just 3-4 chapters a day.
Is it something to boast about?
I'm not sure.
I mean, I guess being able to read through it despite not being exactly entertainment material (except some fun parts) kinda is. So I might feel a tad bit proud about that.
But I'm actually more happy that I did instead.
The reason I'm more happy than proud is because I took awareness of the religion I was in.
I became christian when I was an early teen. I grew up in an agnostic family. My dad was kinda hippie and my mom was into leftist ideas.
So me becoming a christian was a bit orthogonal to their philosophies.
I started assisting a church because I was very alone and misunderstood, and found some people there that seemed to get me, and viceversa.
But as time went on and I got more exposed to christian doctrine, my level of commitment grew.
I wanted to save people from going to hell. It sounds funny, maybe egotistical, but it's true.
3, 4 years of being in the church go by. I collaborate in the church, I make some very personal friendships, I was very deep in church by that point.
I then decide that I should take it to the next level and read the bible. So I did. And unknowingly, it started this feeling in me that I didn't liked being a christian at all.
I'm not gonna deny there are some christian values that are still compatible with today's modern society, such as being a good samaritan, working hard, being honest.
But there were too many verses in both old and new testament that I found morally repugnant,
The ones that made me feel the worst about christianity, though, were the ones that condemned homosexuality with death.
Since my dad was a hippie, he used to be in artsy things, like theater or music, and through that he had some gay friends
And for real, I think they were the nicest and most cheerful people I'd met as a kid. So I could not be part of that anymore.
Let me clarify that I didn't stop being a christian immediately after finishing the bible, but it did start a spark "of "what tf do I even believe in...?"
That spark turned into flame when I started the university, a place where people think for a living.
It's no wonder my mind started completing the puzzle, and slowly I started liking church and christianity less and less.
Until one sunday I didn't want to go, and I didn't, and from then on, I pretty much severed ties with that church and christianity.
Which is crazy considering I went every sunday without interruption for 6 years, and several saturdays too.
Anyhow, that's my story of me getting in n out of christianity. Like in the previous post, it sure how to end this, so go fuck a rock or something.12 -
Overheard from the room next to mine:

Hello everyone, found this place recently, decided to bore you with one (or many) Navy story... tech Navy story. I'll start from the end.
Little backstory: I've deployed a simple domain setup on the ship I served, nothing fancy, a server, a switch, 10 computers, all Windows (details on that at another rant). I enter the ship Monday morning, and the XO tells me that he can't access his online folders.
OK, I say, I'll get to it. I fire up my laptop, try to RDP to the server (I know, I know, burn me at the stake later) no connection. WTF? Is the service down? I try pinging. No luck. I tried pinging the switch. OK. Looking at the switch admin panel, I see the server's port is dead. "OK, probably the cable." (we have old ethernet cables)
So, I drag my ass over to the server (same room with ship comms) with the cable tester to confirm that. What do I see?
The IMBECILES had pulled the plug from the server so that they could charge their mobile phones. I literally slammed my head against the door (calming exercise in case of spontaneous murder impulses - the things you learn at the Academy). My CO was nearby, and lucky for the guys, he heard me yell at them, while throwing mobiles and chargers around.
"But we thought it was OK, we just wanted to charge our-"
I kid you not, I reached for the firefighter's axe.
My CO grabbed me by the collar and dragged me to his room. I explained to him (between two cigarettes) that we MUST get a UPS and a server cabinet (budget constraints in the military are something that will give you people nightmares, trust me). I carefully explained to him that unless we got those, nothing would prevent the next moron from destroying confidential data and me from murdering him.
I plugged in and booted the server, after installing a multi socket extension. Two days after, surprise surprise, the server was off again. That was the first time I opened the door to the CO's room with a low kick. I must have looked like a psycho on drugs, he gave approval for the purchase in twenty seconds flat.
After that, I installed the UPS and the cabinet. Everything went inside, from the UPS to the very plugs. Just a locked box with cables coming out.
One of the guys came to my room, and asked if I could unlock the cabinet so that they could plug a "device" they needed.
I actually reached for my folding knife.
Disclaimer: The story above is TRUE. Even the almost violent parts.23 -

Unpopular opinion:
The "I hate everyone" mentality doesn't make you quirky or unique, it likely just means you're a real pain in the ass to deal with and/or have the social skills of a rock.

Some empty-headed helpdesk girl skipped into our office yesterday afternoon, despite the big scary warning signs glued to the door.
"Hey, when I log in on my phone, the menu is looking weird"
"Uh... look at my beard"
"What"
"Just look at this beard!"
"Uh.... OK"
"Does this look like a perfectly groomed beard"
"Uh... it's pretty nice I guess"
"You don't have to lie"
She looks puzzled: "OK... maybe it could use a little trimming. Uh... a lot of trimming". "I still like it though" she adds, trying hard to be polite.
"I understand you just started working here. But the beard... the beard should make it clear. See the office opposite to this one?"
"Yeah"
"Perfectly groomed ginger beards. It's all stylish shawls and smiles and spinach smoothies. Those people are known as frontend developers, they care about pixels and menus. Now look at my beard. It is dark and wild, it has some gray stress hairs, and if you take a deep breath it smells like dust and cognac mixed with the tears caused by failed deploys. Nothing personal, but I don't give a fuck what a menu looks like on your phone."
She looked around, and noticed the other 2 tired looking guys with unshaven hobo chins. To her credit, she pointed at the woman in the corner: "What about her, she doesn't seem to have a beard"
Yulia, 1.9m long muscled database admin from Ukraine, lets out a heavy sigh. "I do not know you well enough yet to show you where I grow my unkempt graying hairs... . Now get lost divchyna."
Helpdesk girl leaves the scene.
Joanna, machine learning dev, walks in: "I saw a confused blonde lost in the hallway, did you give her the beard speech?"
"Yeah" -- couldn't hold back a giggle -- "haha now she'll come to you"
Joanna: "No I already took care of it"
"How?"
"She started about some stupid menu, so I just told her to smell my cup". Joanna, functional alcoholic, is holding her 4pm Irish coffee. "I think this living up to our stereotype tactic is working, because the girl laughed and nodded like she understood, and ran off to the design department"
Me: "I do miss shaving though"68
