I fucking hate it when apps are not named the same way as the fucking product or company. "Connect" app. Connect fucking what? "Mobile bank". Let me try to search for it using the name of my bank. Haha, oops, I forgot I should rather go fuck myself. MusicCast. You're fucking Yamaha and if I can't find you at Y then gods help me.4

Someone mentioned being frustrated with people who answer "either/or" questions with "yes". I figured out why. They are not human. They are a robot and their processing of language is failing.
A simple question:
Q: The car is red or the car is green?
A: Yes
Breakdown:
The car is red. Yes, True
The car is green. No, False
The car is red OR the car is green.
True OR False
True || False = True
True = Yes
So they dissected the language like a computer treating "or" as a logical OR. This proves they are a robot pretending to be human. They failed the Turing test.7 -
I have this little hobby project going on for a while now, and I thought it's worth sharing. Now at first blush this might seem like just another screenshot with neofetch.. but this thing has quite the story to tell. This laptop is no less than 17 years old.
So, a Compaq nx7010, a business laptop from 2004. It has had plenty of software and hardware mods alike. Let's start with the software.
It's running run-off-the-mill Debian 9, with a custom kernel. The reason why it's running that version of Debian is because of bugs in the network driver (ipw2200) in Debian 10, causing it to disconnect after a day or so. Less of an issue in Debian 9, and seemingly fixed by upgrading the kernel to a custom one. And the kernel is actually one of the things where you can save heaps of space when you do it yourself. The kernel package itself is 8.4MB for this one. The headers are 7.4MB. The stock kernels on the other hand (4.19 at downstream revisions 9, 10 and 13) took up a whole GB of space combined. That is how much I've been able to remove, even from headless systems. The stock kernels are incredibly bloated for what they are.
Other than that, most of the data storage is done through NFS over WiFi, which is actually faster than what is inside this laptop (a CF card which I will get to later).
Now let's talk hardware. And at age 17, you can imagine that it has seen quite a bit of maintenance there. The easiest mod is probably the flash mod. These old laptops use IDE for storage rather than SATA. Now the nice thing about IDE is that it actually lives on to this very day, in CF cards. The pinout is exactly the same. So you can use passive IDE-CF adapters and plug in a CF card. Easy!
The next thing I want to talk about is the battery. And um.. why that one is a bad idea to mod. Finding replacements for such old hardware.. good luck with that. So your other option is something called recelling, where you disassemble the battery and, well, replace the cells. The problem is that those battery packs are built like tanks and the disassembly will likely result in a broken battery housing (which you'll still need). Also the controllers inside those battery packs are either too smart or too stupid to play nicely with new cells. On that laptop at least, the new cells still had a perceived capacity of the old ones, while obviously the voltage on the cells themselves didn't change at all. The laptop thought the batteries were done for, despite still being chock full of juice. Then I tried to recalibrate them in the BIOS and fried the battery controller. Do not try to recell the battery, unless you have a spare already. The controllers and battery housings are complete and utter dogshit.
Next up is the display backlight. Originally this laptop used to use a CCFL backlight, which is a tiny tube that is driven at around 2000 volts. To its controller go either 7, 6, 4 or 3 wires, which are all related and I will get to. Signs of it dying are redshift, and eventually it going out until you close the lid and open it up again. The reason for it is that the voltage required to keep that CCFL "excited" rises over time, beyond what the controller can do.
So, 7-pin configuration is 2x VCC (12V), 2x enable (on or off), 1x adjust (analog brightness), and 2x ground. 6-pin gets rid of 1 enable line. Those are the configurations you'll find in CCFL. Then came LED lighting which required much less power to run. So the 4-pin configuration gets rid of a VCC and a ground line. And finally you have the 3-pin configuration which gets rid of the adjust line, and you can just short it to the enable line.
There are some other mods but I'm running out of characters. Why am I telling you all this? The reason is that this laptop doesn't feel any different to use than the ThinkPad x220 and IdeaPad Y700 I have on my desk (with 6c12t, 32G of RAM, ~1TB of SSDs and 2TB HDDs). A hefty setup compared to a very dated one, yet they feel the same. It can do web browsing, I can chat on Telegram with it, and I can do programming on it. So, if you're looking for a hobby project, maybe some kind of restrictions on your hardware to spark that creativity that makes code better, I can highly recommend it. I think I'm almost done with this project, and it was heaps of fun :D12 -

As a person who takes a lot of tech interviews everyday, here are a few thoughts
1. You DON’T need to know everything, it’s okay to say you don’t know things. Trust me, we know when you’re lying
2. Rule of thumb, the more the number of questions, the more we like you
3. We don’t mind you saying what you’re thinking when we ask a logical question. It might help us understand your approach to the problem and guide you.
4. Don’t google during telephonic interview, your stutter tells us the truth9 -
When I was in 7th grade, my neighbor (a DoD programmer) challenged me to write a sorting algorithm for a hypothetical super limited environment (he said a satellite). It didn’t have any built-in sorting methods, had very limited memory, slow processor, etc. so I needed to be clever about it.
It took me a few nights before i found a solution he liked. The method I came up with counted the number of occurrences of each number in the array and put them in the appropriate spots in a new array. This way it only required O(2n) running time and 2n memory.
I just learned today that this is called the “counting sort” 😄
I’m proud of little 11 year old me.20 -
- We need an android app. Can you do this?
+ Never done that, but I can try.
- Do you even know Java?
+ Not really, but I'll learn fast!
- Any OOP experience?
+ Well...I know CPP.
- 😐
- Will you give me a prototype tonight?
+ Don't know. How about tomorrow?
- Ok.
...
+ *makes a prototype in couple of hours, becomes a Java developer*
Just like that.8 -

Interviewer: Welcome, Mr X. Thanks for dropping by. We like to keep our interviews informal. And even though I have all the power here, and you are nothing but a cretin, let’s pretend we are going to have fun here.
Mr X: Sure, man, whatever.
I: Let’s start with the technical stuff, shall we? Do you know what a linked list is?
X: (Tells what it is).
I: Great. Can you tell me where linked lists are used?
X:: Sure. In interview questions.
I: What?
X: The only time linked lists come up is in interview questions.
I:: That’s not true. They have lots of real world applications. Like, like…. (fumbles)
X:: Like to implement memory allocation in operating systems. But you don’t sell operating systems, do you?
I:: Well… moving on. Do you know what the Big O notation is?
X: Sure. It’s another thing used only in interviews.
I: What?! Not true at all. What if you want to sort a billion records a minute, like Google has to?
X: But you are not Google, are you? You are hiring me to work with 5 year old PHP code, and most of the tasks will be hacking HTML/CSS. Why don’t you ask me something I will actually be doing?
I: (Getting a bit frustrated) Fine. How would you do FooBar in version X of PHP?
X: I would, er, Google that.
I: And how do you call library ABC in PHP?
X: Google?
I: (shocked) OMG. You mean you don’t remember all the 97 million PHP functions, and have to actually Google stuff? What if the Internet goes down?
X: Does it? We’re in the 1st world, aren’t we?
I: Tut, tut. Kids these days. Anyway,looking at your resume, we need at least 7 years of ReactJS. You don’t have that.
X: That’s great, because React came out last year.
I: Excuses, excuses. Let’s ask some lateral thinking questions. How would you go about finding how many piano tuners there are in San Francisco?
X: 37.
I: What?!
X: 37. I googled before coming here. Also Googled other puzzle questions. You can fit 7,895,345 balls in a Boeing 747. Manholes covers are round because that is the shape that won’t fall in. You ask the guard what the other guard would say. You then take the fox across the bridge first, and eat the chicken. As for how to move Mount Fuji, you tell it a sad story.
I: Ooooooooookkkkkaaaayyyyyyy. Right, tell me a bit about yourself.
X: Everything is there in the resume.
I: I mean other than that. What sort of a person are you? What are your hobbies?
X: Japanese culture.
I: Interesting. What specifically?
X: Hentai.
I: What’s hentai?
X: It’s an televised art form.
I: Ok. Now, can you give me an example of a time when you were really challenged?
X: Well, just the other day, a few pennies from my pocket fell behind the sofa. Took me an hour to take them out. Boy was it challenging.
I: I meant technical challenge.
X: I once spent 10 hours installing Windows 10 on a Mac.
I: Why did you do that?
X: I had nothing better to do.
I: Why did you decide to apply to us?
X: The voices in my head told me.
I: What?
X: You advertised a job, so I applied.
I: And why do you want to change your job?
X: Money, baby!
I: (shocked)
X: I mean, I am looking for more lateral changes in a fast moving cloud connected social media agile web 2.0 company.
I: Great. That’s the answer we were looking for. What do you feel about constant overtime?
X: I don’t know. What do you feel about overtime pay?
I: What is your biggest weakness?
X: Kryptonite. Also, ice cream.
I: What are your salary expectations?
X: A million dollars a year, three months paid vacation on the beach, stock options, the lot. Failing that, whatever you have.
I: Great. Any questions for me?
X: No.
I: No? You are supposed to ask me a question, to impress me with your knowledge. I’ll ask you one. Where do you see yourself in 5 years?
X: Doing your job, minus the stupid questions.
I: Get out. Don’t call us, we’ll call you.
