Recently I disassembled this Remington beard trimmer that I have, right. Thinking that I probably just depleted the battery or something like that, and that that's why the fucking thing would turn off after 10 seconds, with a miserable motor speed that could only be caused by what.. 2.5V or something like that? So I kept up with it for a while, and then a few days ago, I finally disassembled the fucking thing.
New 4.2V LiPo battery of my own attached, wicked! The thing has a 2Ah capacity and is fully charged, so fuck all in a big ship, I'ma shave my fucking hair without protection, who cares with 2Ah anyway, given that motors at 4.2V consume only 800-ish mA, right. So I shaved my head, and figured.. holy shit mate, I fucking beat this fucking cunt, fuck you Remington! Planned obsolescence my ass!!!
Just now @xewl sent me a request that made me reconsider this shaver. Some PS3 controller, should be easy enough to fix. But I referenced my shaver so I figured that I might actually check it beforehand.
The original fucking battery has 4V left on it. 4 fucking volts! That ain't gonna trip shit for an overdischarge protection circuit!!! WHY THE FUCK REMINGTON, WHY THE FUCK DID IT (IF ANYTHING) TRIP?! And more importantly, why did you make the motor turn for only 10-ish seconds after charging, 1 year after purchase, despite the fucking cell having 4 fucking volts in it, which is more than plenty to get the thing turning for at least a 60% charge?! Planned obsolescence perhaps, hmm?
But let's say that it was bad contacts or something like that. After all, my probing was a bit intermittent, showing 1.5V (if it's shorting, shouldn't it be in the mV range?) and then 4V at times, until I separated the nickel connectors from the 16500 cell. Why the fuck should that thing short, considering that it's unprotected?! The fucking cell is unprotected, and you Remington are going to let it short? What kind of fucking engineering is that, you fucking braindead morons?!!!
And why do you use a 16500 cell which isn't very standard over a 18650 cell, which is? Again, planned obsolescence? Fucking vile pieces of shit.
Now what's more.. I tried to power on the shaver for a picture for this fucking rant, using a LiPo cell of my own that I used to shave my hair with the other day, to get a nice picture of my little hack. But the fucking thing, despite having 3.89V left in it after that fucking shave, which is more than plenty for a lithium cell, the fucking unit doesn't power on. WHAT THE FUCK REMINGTON?!! That's planned obsolescence at its best, init?!! You vile fucking pieces of shit.
So I guess that this rant is no more one of "I beat these Remington cunts". It is one of "you can bet your fucking ass that planned obsolescence is a thing!!"7 -
[Last year me]: Dammit, javascript is the worst language ever! Where are my var types? Why are there so many frameworks? Why the people are using it? Why? Why?
[Today me after updating my Linkedin profile with my javascript experience and receiving some good job offers almost instantly]: Oh good Lord, thank you for giving Mr. Eich the wisdom to create such a beautiful language, I'll build a new framework as a sacrifice to show my gratitute.1 -
Batteries and power.
Hey guys. I have a question I have to rectify so I can think without doubts.
Let's say I have a sistem with solar power, a 1 lipo battery, one lipo module and arduino + shields and I want to power only by the 🔋.
My question is: is it good practice to charge while discharging at the same time with a lipo module? Won't it damage the batery and incrise the chance of fire? Thank you6 -
We have this guy at the company who always presents good ideas and always suggests new projects. One day he suggested a great project, our boss really liked the idea and gave me the green light to start creating it.
The guy, seeing the opportunity to promote himself, and without consulting me about the deadline, set up a meeting to present the application to the directors, and only then informed me about the deadline. At that moment I did my part, told him that it would not be possible to meet the deadline with all the requirements, something had to be withdrawn, and that's what he did, took a lot of things from the project and we went on like this.
While I was implementing the application, he was always pushing, asking me to do it faster, asking my boss to put me exclusively in his project, and things like that, the boss was always saying that there were not enough people on the team to devote someone exclusively to the project. The guy of course did not agree with that.
At the end the application, without a lot of the initial requirements, was a really mess but ready, he presented to the directors, who in turn liked a lot, and consequently asked to do all the initial requirements and some more. But now those initial requirements had to be made on top of a mess because of all the rush and adaptations.
A few months later, with the change of the board, the guy turned up being my boss, and I've prepared myself to go back to his project with exclusive dedication.
Then came the surprise, when the guy, in the boss position, realized the limitations of the team, instead of putting me to do everything he wanted in that project, he canceled the project entirely and for all the reasons that had already been said to him by the former boss.
Please, don't be like that guy!2 -
As a long time Ubuntu user, last month I upgraded from Xenial to Bionic to try the new Gnome based desktop.
At first I thought it was a good transition, everything was working fine, beautiful UI, nice animations, so I installed all my tools and started the real work... then the problems started. The memory usage was always very high and only getting higher, the animations were stuttering and laggy, and it was having an unrecoverable freeze at least twice a week. Searching the web I was seeing more and more people complaining about freezes, lags, bugs, memory leaks, password input field bugs... damn, how I missed Unity! That was it, Gnome Shell made me miss Unity more and more.
This week I installed Unity 7 and purged Gnome Shell from Bionic. Now I'm happy again!
It's so good to be free of the anxiety caused by the lack of stability of the system, so good to know that the system will not break or freeze if I'm doing a resource intensive task. Now he sh** is working fast and stable, and I'm here wondering why such a good DE could be dumped for something so buggy like Gnome.1 -
