Search - "welding"
Not so much screaming as staring in disbelief, mumbling profanity in his direction...
When my department lead said "I don't think this unit testing hype or code reviews make much sense, it's more efficient to just make a checklist and test the application yourself"
This was the QA department of an aerospace company, we wrote NDT software to do image recognition on xrays of alloy welds and micrometer laser measurements on fuel tank surfaces. Software which is quite mission critical, a single misrecognized welding fault could literally cost up to half a billion dollars — not to mention that it's a very sabotage & espionage sensitive industry.
After raising some hell he was replaced though.3
Today I downloaded SpyKids (2002) movie to refreshen childhood memories.
Saw that scientists were using welding machine and chemicals to make artificial intelligence.6
On the first day of Christmas, the bossman gave to me: The fact that my new computer purchase order needs to be OKed by the CEO and I need to continue working on a 2014 Mac Mini (i5-4260U, 8 Gig RAM, GPU shot by an ESD on the case long ago) for the next year.
On the second day of Christmas, my family gave to me... a good reason to get shitfaced
On the third day of Christmas, getting shitfaced gave to me: A hangover and some urgent plastic welding job that had to be done with a soldering iron. FML, I've had a headache before breathing in pure hydro-cyano-whatthefuckyougetwhenyoumeltplastics
On the fourth day of Christmas, my team gave to me: A legacy, age-old Rails 2 project that was written by an intern and never reviewed, went to prod in 2014 and can't be changed anymore, but needs to be changed after the fact that it has zero test coverage and needs 100 % now to prevent issues and costly manual testing.
On the fifth day of Christmas, devrant gave to me: The Idea that making fun of Christmas songs to get over the sheer amount of dicks that working over the twelve days of Christmas sucks.
To be continued...2
I forged a katana once, under the supervision of a swordsmith. Nothing super special like damascus patterning or anything, but the cutting edge was pretty sharp.
Ugh sorry, lame word jokes.
In terms of software...
Microsoft Office Ribbon (cutting edge at the time, lol). Only as a maintenance drone on a bunch of manual search-and-replace work and merge conflict resolving.
Ariane 6 family of rockets (Welding X-rays and other DICOM quality assurance).
Software for continuous flow chemistry, developing microfluidic PCBs to perform Elisa immunology assays during the Mexican flu outbreak. Idea was to eliminate the need for microplates, expensive robots, microwell washers, etc — just have blood plasma, enzymecoated nanoparticles, antigen, conjugated detection reagents and substrates flowing programmatically through a PCB with a spectrophotometer built in.8
My security knowledge is so bad. But I don't know where should I start.😖
My coworkers know about this, so I don't get involved on related topics.🤤
Last time I asked same question, someone gave me link, and it all about DIY welding metal tubes into a security door.🤦♂️
Any better suggestion?13
I can never get over this 😥
We were taught 5-6 subjects of electrical or mechanical engineering in out freshman year 😃 and our course is called "computer science and engineering".
We had ONE subject in the whole fucking year that was related to the course,called "introduction to computer"!!!!
The second semester of the freshman year had no subject remotely close to computers, but yeah we learnt about thermodynamics and beams and Trusses and motors and welding 😒.
They should have also told us what we are supposed to do with that knowledge 😒.
What's the point!!!!
Will is make us a mechanical engineer 😒?
Also have you forgotten we are here to learn about computers and not about the tension in the rope of the pulley 😒?
Also we have no subjects,in the 4 year course about actual development 😃 not even old school web development.
Fucking hate this shit20
I thought I'd opened every shitty type of Chinese-grade electronics by now. Glued in shit, ultrasonically welded shit, potted shit. And occasionally the now very rare piece of electronics that has actual screws.
Until now. Remington, apparently yet another company filled with certified enganeers. My razor is from them, and I wanted to open it up to see why the lithium cell inside was failing, and to replace it with a bigger one. 2 screws in the back of the unit, Phillips head. But holy fuck, those things sat in there more tightly than the glory hole of the Asian girl that probably assembled this thing. Externalizing our own features in our craft? Check!
Pretty hard to remove them but that's fine. But the unit didn't open up, and there seems to be no screws left. I guess that they leveled up their level of certified enganeering and actually used both screws and ultrasonic welding. Because why wouldn't you, right?!
Yesterday I did some experiments with my lab bench power supply to see if everything was working as it should, and whether my newly acquired laptop (old business laptop from 2004) would still power up. Noticed that it did, and left the thing charging for a while - its battery was completely drained. But after letting it sit for a few hours, one of my switches wouldn't turn off anymore.
The lab bench power supply has a 250V 2.5A (625W) rated switch on the AC side, connected to a 50V 10A (500W) AC-DC power supply. The DC side of that is then connected to 2 DPS5005 units, of which one was driving 50W of power into the laptop.
The experiment went reasonably well, the AC-DC power supply was loud but stayed cool like a cucumber. The switch however wouldn't turn off anymore after a few hours. Today I've desoldered that and put on a new one, and did a failure analysis. Turns out that it was a rocker switch (so there's a little nub in there that moves a piece of metal back and forth) and that the contacts of the switch (the piece of metal and the inside of the connector piece) were welded together.
However, the only thing that I know of that causes this welding is when loads are switched off, and an arc is generated. This wasn't the case here - it was just kept on for a couple of hours, with (accounting for power losses across the circuits) 80W going through it at most. I never expected that to cause a weld. Any clue as to why this happened? It really boggles my mind, and I don't want the switch that's currently in there to face the same fate.12
Does anybody here know of some sort of blackout glasses? (which cover the entire eyes, not sunglasses which do exist in high filters, but leak sunlight at the bottom, top and sides)
My recent lifestyle has lead me to absolutely dying at the morning when I go sleep, because of the extreme sunlight, peaking through all cracks.
I am just fine during the day when I do my walks or drive to the store etc, but after a long night I just get very light and sound sensitive.
I think a decent amount of years ago, I saw somebody use some sort of small scale welding goggles for something similar, but I can't find any that are dark enough or aren't costing like buying a beach house in malibu.
Also "photophobia glasses", which actually seem to be for that purpose, cost like two malibu beach houses and a helicopter to top it off, because they abuse and cash on the fact that it has remote help to people that suffer from it.
I did also try just using blackout curtains for that purpose, but as said, there's always that one small crack where it leaks through and absolutely flashbangs me.
So it would be nice to have some glasses that filter pretty much 99% of light, but still allow me to navigate through my appartment, without having to break a leg or crack my neck (which would solve the problem atleast)22
It's weird listening to my father "rant" about all the things he has to fix when visiting his parents, some welding, changing tire and switching lightbulbs. When he does the exact same thing with me regarding laptops, routers, smartphones and tablets..2
I just finished up an absolute cesspool of a project. I was seriously reconsidering a career change to something less stressful, like welding on a high-rise building, or capturing Somali pirates.
Next project is supposed to be a walk in the park, and probably still will be.
MGR: You're starting a new project next week. Prismic for the CMS, and NextJS.
ME: Oh, okay, cool. Well, let me get up to speed on Prismic and Next since I haven't used either of those.
Spent some time last week - easy enough, nothing really new/ground breaking here.
Sprint 0.5 Kick off meeting today
MGR: By the way, we're still using Prismic for the CMS, but we're gonna go ahead and use Gatsby instead of Next.
Me: ... *facepalm5
Have programmed process control machines to handle nuclear waste, motion control, welding, tank inspection, joysticks, and more...
Never learned to program my VCR...
ZNC shenanigans yesterday...
So, yesterday in the midst a massive heat wave I went ahead, booze in hand, to install myself an IRC bouncer called ZNC. All goes well, it gets its own little container, VPN connection, own user, yada yada yada.. a nice configuration system-wise.
But then comes ZNC. Installed it a few times actually, and failed a fair few times too. Apparently Chrome and Firefox block port 6697 for ZNC's web interface outright. Firefox allows you to override it manually, Chrome flat out refuses to do anything with it. Thank you for this amazing level of protection Google. I didn't notice a thing. Thank you so much for treating me like a goddamn user. You know Google, it felt a lot like those plastic nightmares in electronics, ultrasonic welding, gluing shit in (oh that reminds me of the Nexus 6P, but let's not go there).. Google, you are amazing. Best billion dollar company I've ever seen. Anyway.
So I installed ZNC, moved the client to bouncer connection to port 8080 eventually, and it somewhat worked. Though apparently ZNC in its infinite wisdom does both web interface and IRC itself on the same port. How they do it, no idea. But somehow they do.
And now comes the good part.. configuration of this complete and utter piece of shit, ZNC. So I added my Freenode username, password, yada yada yada.. turns out that ZNC in its infinite wisdom puts the password on the stdout. Reminded me a lot about my ISP sending me my password via postal mail. You know, it's one thing that your application knows the plaintext password, but it's something else entirely to openly share that you do. If anything it tells them that something is seriously wrong but fuck! You don't put passwords on the goddamn stdout!
But it doesn't end there. The default configuration it did for Freenode was a server password. Now, you can usually use 3 ways to authenticate, each with their advantages and disadvantages. These are server password, SASL and NickServ. SASL is widely regarded to be the best option and if it's supported by the IRC server, that's what everyone should use. Server password and NickServ are pretty much fallback.
So, plaintext password, default server password instead of SASL, what else.. oh, yeah. ZNC would be a server, right. Something that runs pretty much forever, 24/7. So you'd probably expect there to be a systemd unit for it... Except, nope, there isn't. The ZNC project recommends that you launch it from the crontab. Let that sink in for a moment.. the fucking crontab. For initializing services. My whole life as a sysadmin was a lie. Cron is now an init system.
Fortunately that's about all I recall to be wrong with this thing. But there's a few things that I really want to tell any greenhorn developers out there... Always look at best practices. Never take shortcuts. The right way is going to be the best way 99% of the time. That way you don't have to go back and fix it. Do your app modularly so that a fix can be done quickly and easily. Store passwords securely and if you can't, let the user know and offer alternatives. Don't put it on the stdout. Always assume that your users will go with default options when in doubt. I love tweaking but defaults should always be sane ones.
One more thing that's mostly a jab. The ZNC software is hosted on a .in domain, which would.. quite honestly.. explain a lot. Is India becoming the next Chinese manufacturers for software? Except that in India the internet access is not restricted despite their civilization perhaps not being fully ready for it yet. India, develop and develop properly. It will take a while but you'll get there. But please don't put atrocities like this into the world. Lastly, I know it's hard and I've been there with my own distribution project too. Accept feedback. It's rough, but it is valuable. Listen to the people that criticize your project.9
I'm at my Community College as a member of the engineering club requesting funds for a software and hardware-related physical project.
The code was mostly pre-written in Python from a university already, but we needed to build essentially a gaming-level PC to run it, do some welding and metalwork for the hardware, cables, et citera. I don't want to get too detailed in case anyone involved is reading this story.
To get funding, we needed to go before the student senate. I didn't go the first time, but later when we needed more funding for the project to do expansions, we attended.
I came in with a few pages of documentation explaining how the project operated, it's scope, and why we needed the additional $500 on top of the previous $1000 or so spent. I went in woefully behind the times on what a student senate meeting was like.
For starters, I thought this would be somewhat formal, being "Student Senate" in Week 8, and prepared to defend my project fully. Instead, we spent the first 15 minutes going around the table explaining what animal we would be and why, if we had to turn into an animal. It just kept going hilariously, painfully downhill from there.
They did ask some questions about what my project was and how it operated (as not many had seen it), and they wanted explanations even though it was clear absolutely nobody else in the room understood anything. My partner virtually shut down and let me do all the talking for my project and his because he couldn't take the ignorance of some of the questions and the assorted nonsense spread throughout the meeting.
Amazingly, we got funding. We had to sit for the rest of the meeting though, which (among other things) included a segment about whether we should create a new committee called the "Fundamental Insecurities committee" to help out with, well, "Fundamental Insecurities." There was only one member on this proposed committee.
When I brought up the question on why we were making a one-person committee alongside the, like, three one-person committees already in existence, they congratulated me for asking good questions and said I should come more often. They then said the exact same thing again when I pointed out there were better names than "Fundamental Insecurities." It's such a reality check that you are trying to impress people to get funding, when you can't help but feel that everyone is an utter idiot in the back of your head.
Almost a year later, I had to go back with a list of parts we needed. I wrote a whole complex list of things we needed for the project. Even though they tried to ask questions about what certain parts were (to appear like they weren't totally incompetent), and despite asking questions about a bunch of the items, nobody cared about what the $10 for "C418" was (google it if you don't get this joke). I spent about 30 minutes talking with them and succeeded in getting $600 more in funding. We then, to my surprise, spent less than 5 minutes debating whether to send 2 students on a field trip for $700. 30 minutes for $600, for a permanently installed project. <5 minutes for a $700 one-time thing.
And, because this is already a long rant, here's one more thing: The Student Senate's voting rules initially gave everyone who showed up 1 vote. We're all students, we all get a say, right?
Well, I soon put together that Student Senate had fairly low attendance. Engineering Club had high attendance. Student Senate and Engineering Club took place at the same date and time. I then, of course, asked why we couldn't bring the whole Engineering Club into Senate one day, and then proceed to pass an order by simple majority saying that all Student Life funding goes to us.
They then said that the administrators (the heads of Student Senate) could override that, but I pointed out that kind of defeats the purpose of voting in the first place. They then switched script and said they wouldn't do that and would honor such a vote. Shortly after, they changed the rules saying that you only get a vote on your 2nd consecutive visit; and again said I should visit more often because I was brilliant.
You can't make this stuff up.3
Lost one day mounting my CNC.
Still on the basics...
Found out that I baddly welded the two fucking easy drivers and made a bad connection I can't undo now.
So the drivers are always on and stepping :(
5€ to the trash.4
Found my grandmother's Vista laptop from '07. It has 3 problems:
1. Battery lasts 15 seconds at full charge (not a shock)
2. Plastic shell around screen is cracked (not badly, likely fixable with plastic welding)
3. IT'S SLOW AS FUCK
Point 3 is strange, considering the specs:
AMD dual-core CPU at 1600MHz (better than MY laptop...)
Some NVidia onboard GPU thing (no clue)
2x 512MB DDR2-L (immediately swapped out with 1x2GB and 1x1GB, the most we have at the house)
What I noticed, though, is that it's got a SOCKETED CPU (a rarity only like 3 years later), specifically an S1 socket. There's an AMD Phenom quad-core clocked at 1800MHz with that socket, for $16 on eBay no less!
However, it's a different processor family, so I don't know if it'd work in the board...
Anyone think it'd work?9
