Search - "wifi usage"
First time poster here. Please be nice :)
My biggest workaround is one that's being currently deployed to 40 truck drivers (trucking company here), preventing printers being out of usage while on the road. We also have to use HP ePrint to wirelessly print documents, but that's another story for another time I guess :)
CEO asked us to install wifi printers in our 40-ish trucks which has wifi on board. However he's always picking one of the cheapest options possible, so we got consumer grade printers (Laserjet 1002w). Those printers often disconnects without getting back on the truck wifi network EVER. I have to get physically in the truck, wire the printer via USB onto my laptop and reconfigure Wifi on it with the HP Windows tool. This means lots of printer downtime, which always happens when the drivers are three timezones away from our office
Then I thought: "What if I could sniff what HP sends via USB while I (re)configure the printer, and replay whats being sent later? Our trucks all have an Android tablet with a USB type-A connector with host capability, so I could write a small app that replays the config when plugged in by the user.
Three days of hacking around later, I have a working app. By chance, HP printers (or at least those models we have) uses HTTP POST via USB, so I could easily replay the request.
Edit: the end result is that truck drivers just plug the printer to their tablet, press "reconfigure" in a home made Android app, printer is reconnected to the truck and they're good to go. They don't have access to the network nor know enough to debug themselves anyways14
My dad has an acquaintance - let's call him Tom. Tom is an gynecologist, one of the best in Poznań, where I live. He's a great guy but absolutely can not into tech of any kind besides his iPhone and basic PC usage. For about a year now I've been doing small jobs for him - build a new PC for his office, fix printer, fix wifi, etc. He has made a big mistake few years ago by trusting a guy, let's call him Shitface, with crating him software for work. It's supposed to be pretty simple piece of code in which you can create and modify patient file, create prescription from drugs database and such things. This program is probably one of the worst pierces of code I've ever seen and Shitface should burn for that. Worse, this guy is pretentious asshole lacking even basic IT knowledge. His code is garbage and it's taking him few months to make small changes like text wrapping. But wait, there's more. Everything is hardcoded so every PC using this software must have installed user controls for which he doesn't have license and static IP address on network card.
Tom asked me to build him a new PC that will be acting like a server for Shitface's program. He needs it in Kalisz (around 150 km from my place). I Agred (pun intended) and after Tom brought me his old computer I've bought parts and built a new one. I have also copied everything of value and everything took me around three hours.
Everything was ready but Shitface's program. I didn't know much about it's configuration so when I've noticed that it's not working even on the old PC I got a bit worried. Nevertheless I started breaking everything I know about it and after next three hours I've got it somewhat working. Seeing that there's still some problems with database connection (from Windows' Event Viewer) I wrote quick SMS to Shitface asking what can be wrong. He replied that he won't be able to help me any way until Monday (day after deadline). I got pissed and very courteously asked him for source code because some of libraries used in this project has license that requires either purchase of commercial license or making code open source. He replied within few minutes that he'll be able to connect remotely within next 10 minutes. He was trying to make it work for the next hour but he succeeded. It was night before deadline so I wrapped everything up and went to bed thinking that it won't take me more than an hour to get this new PC up and running in the office. Boy was I wrong.
Also, curious about his code, I've checked source and he is using beautiful ponglish (mixed Polish and English) with mistakes he couldn't even bother to fix. For people from Poland, here's an example:
So I drove to Kalisz and started working on making everything work. Almost everything was ready so after half an hour I was done. But I wanted to check twice if it's all good because driving so far second time would be a pain. So I started up Shitface's program, logged in, tried to open ANYTHING and... KABUM. UNHANDLED EXCEPTION. WTF. I checked trace and for fuck sake something was missing. Keep in mind that then I didn't know he's using some third party control for Windows Forms that needs to be installed on client PC. After next fifteen minutes of googling I've found a solution. I just had to install this third party software and everything will work. But... It had to be exactly this version and it was old. Very old. So old that producent already removed all traces of its existence from their web page and I couldn't find it anywhere. I tried installing never version and copying files from old PC but it didn't work. After few hours of searching for a solution I called Mr Shitface asking him for this control installation file. He told me that he has it but will be able to send it my way in the evening. Resigned I asked for this new PC to be left turned on and drove home. When he sent me necessary files I remotely installed them and everything started working correctly.
So, to sum it up. Searching for parts and building new PC, installing OS and all necessary software, updating everything and configuring it for Tom taste took me around what, 1/3 of time I spent on installing Mr Shitface's stupid program which Tom is not even happy with. Gotta say it was one of worst experiences I had in recent months. Hope I won't have to see this shit again.
Fortunately everything seems to work correctly. Tom hasn't called me yet with any problems. Mission accomplished. I wanna kill very specific someone. With. A. Spoon.2
Windows 10 update: no more wifi, no more trackpad, 60MB more RAM usage when idle.
So I have this 13 year old cousin who's pretty determined to follow my footsteps as a developer someday. He really likes gaming and all internet stuffs. His future plans makes me happy since I may finally have a relative that is a developer. But darn it! He's kinda weird coz he still throws tanrums. One of his major tantrums(which happened again last night) is that he wants the wireless Karaoke machine to be turned off because he thinks that it's slowing down the internet. It was his sister's birthday party and the guests are partying. I've told him many times that the signal for the karaoke is different from that of the router which has nothing to do with the internet slowing down. It must be caused by q device that is updating some apps or whatever. We live in the philippines and our internet provider is quite fast but it has this stupid fair usage policy that caps our bandwidth to a minimum speed if we reach a certain amount of data usage. Since he goes to youtube everyday in 480 and 720p, I explained it to him that it was one of the causes.
Last night, I almost got triggered because I wanted him to believe about the wifi being different to that of the karaoke machine's radio and that it is not connected to the wifi and not using data. I also told him about different kinds of wireless signals which I studied as a Software Engineering student back then and yet he still doesnt believe me. And what almost triggered me is that i saw his steam client updating while watching youtube. I told him that was it. But instead of agreeing, he refused to believe me and just told me that steam is just updating and he's not downloading anything which made me think why he keeps going to youtube, because...he's not downloading. Oh God! Good luck to this kid. 😂5
So, whenever I delay windows 10 update restart a few times, things start breaking. Wifi doesn't work, 100% cpu, ram or mem usage, sound problems etc. And all this goes away once I submit my soul and update. I'm sick of this shit 😡. Today I got a BSOD after which it updated and things seem fine FOR NOW.
Does this happen to other Win 10 users?9
