I've just disassembled this LED floodlight that I bought a while ago. It's some stupid little cheapie from a dollar store, so I figured that there'd be shit inside. But I wanted that LED cob.. a power LED :3

Well, shit wasn't too far off from the truth. The component choice is reasonable, but the design of the bloody thing.. batshit insane. The LED floodlight is powered by 4 AAA batteries, connected in series. So 6VDC. That then goes into this little tactile pushbutton, into the LED cob and then a 4.7 ohm resistor.

Well that's a pretty easy circuit.. let's remove the batteries and the casement, and put it on the lab bench power supply. Probes connected to the circuit with only the resistor and the LED cob in between (I didn't want to deal with the switch). Power supply set to 6V, current limiting to 500mA, contact!! And it works, amazing! So I let it run for a while to see that nothing gets too hot.. hah. After a minute or so, smoke would come out.. LED cob was a bit warm to the touch but nothing too bad. But the resistor.. I could cook water on it if I wanted to! 100 fucking °C, and rising. What the F yo?!

So I figured that I didn't want to put the resistor in between there. Just the LED cob now, which apparently has a forward voltage somewhere between 3.2V and 3.3V depending on how I set the current (500mA and 600mA respectively). Needed a bigger heatsink though, so I jammed one of my aluminium heatsinks on there. And it worked great! Very bright too, as it takes between 1.6 and 2W of power. Just for a comparison, the lighting in my living room is 4x5W and the ones on top of my dining table are 2x3W (along with some TL bar that my landlord put there.. fluorescent I think). So yeah, 2W is quite a lot for an LED, especially when it's all concentrated into one tiny spot.

That said, back to the original design with the resistor. 2 questions I have for that moron that designed this crap. First, why use a resistor for a power LED?! They needlessly waste power, and aren't good choices for anything that consumes more than 100mA. You should use PWM for these purposes, or tune your voltage on the supply side. Second, why go with 6V when your forward voltage is 3.3 at most? Wouldn't it make more sense to use 3 batteries with 4.5V? Ah, but I know the answer to the second one. AAA cells aren't rated for high loads like this. So that's likely why the alkaline cells that I had in there before have started leaking. Thanks, certified piece of shit!

Honestly, consumer electronics are such a joke... At least there's some components that I can salvage from this crap. Mainly the LED cob, but also the resistor and the tactile pushbutton perhaps.

One last remark that I'd like to make. This floodlight was cheap garbage. But considering that you can't do it well at that price, you just shouldn't do it. You know why? Because consumers always go for the cheapest. Makes a lot of money to build at rock bottom prices and make shit, but it damages the whole industry, since now the good designs will go out of business. That's why consumer electronics is so full of crap nowadays. Some unethical profiteering gluttons saw money, and they replaced the whole assortment with nothing but garbage. I'm sure that there's a special place in hell for that kind of people.

Dear Current Workplace,

Fuck you, for the reasons enumerated below.

Fuck your enterprise grey blue offices, the stifling warm air of a hundreds of bodies and sub par "development laptops".

Fuck your shitty carbonated water machines which were a cost saving measure over decent drinkable water.

Fuck your fake "flexi time", "you can do home office whenever you want" bullshit. You're still inviting me to mandatory meetings at 09:00 regularly.

Fuck your shitty, in house, third part IT provider sister company. They're the worst of all worlds. If it was in company, we'd get to give out to them, if it was an external company we'd fire them. And yes, when I quit I will quote the dumpster fire that is our corporate VPN as a major factor.

Fuck your cheery, bland, enterprise communication. Words coming under the corporate letterhead seem to lose all association with meaning. Agile, communication, open are things you write and profess to respect, but it seems your totally lack understanding of their meaning.

Fuck your client driven development. Sometime you actually have to fix the foundations before you can actually add new features. And fuck you management who keep on asking "why are there so many bugs and why is it always taking longer to deliver new releases". Because of you, you fucknuts, Because you can't say "NO" to the customer. Because you never listen to your own experienced developers.

Fuck your bullshit "code quality is important to us" line. If it's so important, then let us fix the heap of shit you're selling so that it works like a quasi functional program.

Fuck you development environment which has 250 projects in a single VS solution. Which takes 5mins plus to compile on a quad core i7 with 32 gb of ram.

Fuck this bullshit ball of mud "architecture". I spend most of my time trying to figure out where the logic should go and the rest of the time writing converters between different components. All because 7 years ago some idiot "architect" made a decision that they didn't have to live with.

Actually, fuck that guy in particular. Yeah, that guy who was the responsible architect for the project for 4 years and not once opened the solution to look a the code.

Fuck the manual testing of every business process. Manual setup of the entities takes 10mins plus and then when you run, boom either no message or some bullshit error code.

Fuck the antiquated technology choices which cause loads of bugs and slow down development. Fuck you for forcing me to do manual tests of another developers code at 20:00 on a Friday night because we can't get our act together to do this automatically.

Fuck you for making sure it's very clear I'm never going to be anything but a code monkey in this structure. Managers are brought in from outside.

Fuck you for being surprised that it's hard to hire competent developers in this second rate, overpriced town. It's hard to hire anywhere but this bland shithole would have anyone with half a clue running away at top speed.

Fuck you for valuing long hours and loyalty over actual performance. That one guy who everyone hated and was totally incompetent couldn't even get himself fired. He had to quit.

Fuck you for your mediocrity.

Fuck you for being the only employer for my skill-set in the region; paying just well enough that changing jobs locally doesn't make sense, but badly enough that it's difficult to move.

Fuck you for being the stable "safe" option so that any move is "risky".

Fuck your mediocrity.

Fuck you for being something I think about when I'm not at work. Not only is it shit from 9 to 5 you manage to suck the joy out of everything else in my life as well?

Fuck you for making me feel like a worse developer every day I work here. Fuck you for making every day feel like a personal and professional failure. Fuck you for making me seriously leave a career I love for something, anything else.

Fuck you for making the most I can hope for when I get up in the morning is to just make it until the night.

I've recently received another invitation to Google's Foobar challenges.

A while ago someone here on devRant (which I believe works at Google, and whose support I deeply appreciate) sent me a couple of links to it too. Unfortunately back then I didn't take the time to learn the programming languages (Python or Java) that Google requires for these challenges. This time I'm putting everything on Python, as it's the easiest language to learn when coming from Bash.

But at the end of the day.. I am a sysadmin, not a developer. I don't know a single thing about either of these languages. Yet I can't take these challenges as the sysadmin I am. Instead, I have to learn a new language which chances are I'll never need again outside of some HR dickhead's interview with lateral thinking questions and whiteboard programming, probably prohibited from using Google search like every sane programmer and/or sysadmin would for practical challenges that actually occur in real life.

I don't want to do that. Google is a once in a lifetime opportunity, I get that. Many people would probably even steal that foobar link from me if they could. But I don't think that for me it's the right thing to do. Google has made a serious difference by actually challenging developers with practical scenarios, and that's vastly superior to whatever a HR person at any other company could cobble together for an interview. But there's one thing that they don't seem to realize. A company like Google consists of more than just developers. Not only that, it probably consists - even within their developer circles - of more than just Python and Java developers. If any company would know about languages that are more optimized such as C, it would be Google that has to leverage this performance in order to be able to deliver their services.

I'll be frank here. Foobar has its own issues that I don't like. But if Google were a nice company, I'd go for it all the way nonetheless - after all, they are arguably the single biggest tech company in the world, and the tech industry itself is one of the biggest ones in the world nowadays. It's safe to say that there's likely no opportunity like working at Google. But I don't think it's the right thing. Even if I did know Python or Java... Even if I did. I don't like Google's business decisions.

I've recently flashed my OnePlus 6T with LineageOS. It's now completely Google-free, except for a stock Yalp account (that I'm too afraid to replace with my actual Google account because oh dear, third-party app stores, oh dear that could damage our business and has to be made highly illegal!1!). My contacts on that phone are are all gone. They're all stored on a Google server somewhere (except for some like @linuxxx' that I consciously stored on device storage and thus lost a while back), waiting for me to log back in and sync them back. I've never asked for this. If Google explicitly told me that they'd sync all my contacts to my Google account and offer feasible alternatives, I'd probably given more priority to building a CalDAV and CardDAV server of my own. Because I do have the skills and desire to maintain that myself. I don't want Google to do this for me.

Move fast and break things. I've even got a special Termux script on my home screen, aptly named Unfuck-Google-Play. Every other day I have to use it. Google Search. When I open it on my Nexus 6P, which was Google's foray into hardware and in which they failed quite spectacularly - I've even almost bent and killed it tonight, after cursing at that piece of shit every goddamn day - the Google app opens, I type some text into it.. and then it just jumps back to the beginning of whatever I was typing. A preloader of sorts. The app is a fucking web page parser, or heck probably even just an API parser. How does that in any way justify such shitty preloaders? How does that in any way justify such crappy performance on anything but the most recent flagships? I could go on about this all day... I used to run modern Linux on a 15 year old laptop, smoothly. So don't you Google tell me that a - probably trillion dollar - company can't do that shit right. When there's (commercialized) community projects like DuckDuckGo that do things a million times better than you do - yet they can't compete with you due to your shit being preloaded on every phone and tablet and impossible to remove without rooting - that you Google can't do that and a lot more. You've got fucking Google Assistant for fucks sake! Yet you can't make a decent search app - the goddamn thing that your company started with in the first place!?

I'm sorry. I'd love to work at Google and taste the diversity that this company has to offer. But there's *a lot* wrong with it at the business end too. That is something that - in that state - I don't think I want to contribute to, despite it being pretty much a lottery ticket that I've been fortunate enough to draw twice.

Maybe I should just start my own company.

A taxi booking platform to support functioning B2B taxing booking company that was turning over 15 million per year.

It offered portals for B2B and B2C. Rather simple concept.

Business or client raise a booking, booking is submitted to a 3rd party taxi firm we manage the booking throughout its lifetime for the client.

We had an existing legacy product in place that needed redeveloping.

Management sunk many, many millions of pounds into the project, it never lunch and teh company was sold off twice will extreme losses each time. First sale was in the millions and the second was for 500k.

This was a result of poor technical choices made by past lead developers and extremely poor choice of management who cared more for managing their reputation as they were self aware of how much knowledge they lacked.

The technical aspect of the company was created a child company of the parent. This child company was responsible for the downfall of the parent which was functioning well and making a profit.

The company as a whole has since been liquidated thanks to that project. Many out of a job.

I jumped ship after 8 months as I couldn't continue to work with the crazy management. By crazy I mean they should have been in a tincan.

I explained last week in great detail to a new team member of a dev team (yeah hire or fire part 2) why it is an extremely bad idea to do proactive error handling somewhere down in the stack...

Example
Controller -> Business/Application Logic -> Infrastructure Layer

(shortened)

Now in the infrastructure layer we have a cache that caches an http rest call to another service.

One should not implement retry or some other proactive error handling down in the cache / infra stack, instead propagate the error to the upper layer(s) like application / business logic.
Let them decide what's the course of action, so ...
1) no error is swallowed
2) no unintended side effects like latency spikes / hickups due to retries or similar techniques happens
3) one can actually understand what the services do - behaviour should either be configured explicitly or passed down as a programmed choice from the upper layer... Not randomly implemented in some services.

The explanation was long and I thought ... Well let's call the recruit like the Gremlin he is... Gizmo got the message.

Today Gizmo presented a new solution.

The solution was to log and swallow all exceptions and just return null everywhere.

Yay... Gizmo. You won the Oscar for bad choices TM.

Thx for not asking whether that brain fart made any sense and wasting 5 days with implementing the worst of it all.

"Let the design team be the design experts. Your job is to be the business expert. Ask them how their design solutions meet your business goals. If you trust your design team, and they can explain how their recommendations map to those goals, you’re fine. If you neither trust them, nor can they defend their choices it’s time to get a new design team." - Mike Monteiro

Taking a class at my local university for fun where the point of the class is to build some kind of project for local companies. The teacher talks a lot about Wordpress and how great it is... He's not a dev, and has only worked as a business consultant/pm.... It's gonna be a long semester, but at least he's funny and has good choices in tv shows to include in his lectures.

I subscribe to many copywriting newsletters. Here's an article that shows how it's like on "the other side", marketers struggle, too.

How Kevin's Massive Mistake
Completely Changed His Life

Kevin H. made a huge mistake.

The biggest, he would say, if he could tell you himself.

And he knew it immediately.

It was, he said, "instant regret."

Within milliseconds, he was asking himself "What have I done..."

Kevin, see, had just jumped the rail of the single most popular suicide spot in the world, the Golden Gate Bridge.

On average, the site gets another distraught jumper every two weeks. Kevin was one of them.

It wasn't like he hadn't tried to quiet the voices in his head. Therapy, drugs, hospitalization.

Time to die, those voices still said.

And yet, in the minutes his bus dropped him off at the bridge, he hesitated and paced with tears in his eyes.

"I told myself if just one person comes up to me and asks if I'm okay... if one person asks if they can help... I won't do it. I'll stop and tell them my whole story..."

But nobody did, so he jumped.

It was in those next milliseconds, he would later say, he knew it was the biggest mistake of his life.

He didn't want to die.

But now, he was sure, it was too late.

From its highest point, it's a 245-foot plummet into the icy bay waters below.

Out of the 1,700 people that have jumped from the bridge since it first opened in 1937, only 25 have survived.

Kevin, against all odds, would be one of them.

He slammed into the water like hitting concrete. Three of his vertebrae instantly shattered.

When he surfaced, he couldn't hold his own head above water. But, incredibly, a sea lion kept pushing him up.

The Coast Guard soon arrived and pulled him out.

From there, he began a long recovery that required intense surgery, physical therapy, and psychiatric care.

While still under treatment, a priest urged him to give a talk to a bunch of seventh and eighth graders.

Afterward, they sent him a pile of letters, both encouraging and full of their own pained thoughts.

He also met a woman.

Today, Kevin lives in Atlanta and he's been happily married for the last 12 years.

And he tours the country, sharing his story.

So why re-tell it here?

Obviously -- I hope -- you don't get lots of copywriters looking to snuff it after a flopped headline test.

Just the same...

We've talked a lot in this space about the things one needs to get by in this biz.

My friend and colleague Joe, over at the publishing powerhouse Agora Financial, likes to list requirements.

You need intense curiosity...

You need a killer work ethic...

And you must, MUST have... resilience.

Meaning, you must have or find the capacity to bounce back from failure and flops, even huge ones.

Now, again, Kevin's story is an extreme and in this context -- I hope -- a hyperbolic example of somebody giving up. In the worst way possible.

It is also, though, a metaphor.

See, I get a lot of notes from some of you guys... and at conferences, I get to talk to a lot of people...

And I often get the sense, from some folks, that they're feeling a little more overwhelmed than they let on.

Some are just starting out, and they've got a lot on the line. For some, it's everything. And some are desperate to make it work.

Because they have to, because their pride or livelihoods or a family business is at stake, because it's a dream.

And yet, they're overwhelmed by all the tips and secrets... or by piles of confusing research or ideas...

For others, even had some success, but they're burned out, feel antiquated, or feel like "imposters" that know less than they let on, in an industry that's evolving.

To all those folks... and to you... I can only say, I've been there. And frankly, go back there now and again.

Flops happen, failures happen. And you can and will -- even years and decades into doing this -- make the wrong choices, pick the wrong projects, or botch the right ones.

The legendary Gene Schwartz put it this way, according to a quote spotted recently in fellow writer Ben Settle's e-letter...

" A very good copywriter is going to fail. If the guy doesn't fail, he's no good. He's got to fail. It hurts. But it's the only way to get the home runs the next time."

Once more, nobody -- I hope -- is taking the trials of this profession hard enough to make Kevin's choice.

And believe me, I don't mean to make light of the latter. I just want to make sure we hit this anvil with a big hammer. To drive home the point that, whatever your struggle, be it with this biz or something bigger, that you don't want to give up. Press on.

As Churchill put it, "Success, is the ability to go from failure to failure without losing your enthusiasm."

Or even more succinctly when he said, "If you're going through hell, keep going."

Because it's worth it.

Should I be optimistic about my profession and growth as an android developer, or should i start gaining experience in other domains?

I am currently a Junior Android Developer in a small company which is a subsidiary of a bigger company (TATA) . I currently hold a working experience of 3+ years but in last 5 years , I have mainly explored Android App development the most. I did courses in it, then internships, then switched jobs to reach a decent salary package (more than INR 10 lakh per annum).

Recently I have been pretty worried regarding my career choices and i can't seem to be optimistic about my role as a mobile engineer. I joined my current company 4 months ago, but my switch this time gave me a hike of -10% (you read that right, it was a negative increment since previous company was asking me to relocate and i had no choice but to take this offer)

This switch made me worried not just because of the salary decrement but as a worthy candidate too. I know my tech stack well , but this time, I had very less options. I feel that the demand of a mobile engineer seems to be very less and I am not sure if its only me or for everyone in the same space as I am.

So , are jobs of Native Android Development really dying? My goal is to reach at premium salaries of INR 80-90 lakhs or 1-2 crores per annum, so can I reach there while just being a good android engineer? I am not sure what to run for. Please help

Some paths that i came to conclusion are for me, based on my limited knowledge are :

CONTINUE ON YOUR PATH : Stay in 1 place , grow as an engineer, get your salary/ role increase slowly and you will probably be able to reach that amount in 5-6 years

SWITCH YOUR PATH TO OTHER TECH SKILL : Do web frontend/backend courses in your free time, then grab a job of 4-6 LPA , start as a basic web dev, grow into senior dev and then reach that amount in 5-6 years (coz frontend/backend devs are the real deal?)

SWITCH YOUR PATH TO HIGHER STUDIES : do courses to crack foreign exam papers, then take out all your savings and got to foreign to pursue some masters in management, then do a job there and get settled / come back to India and grab a better paying job as a manager, then grow/switch into lead managerial roles and earn the goal amount in 5-6 years (coz foreign studies are the real deal/ foreign countries give fair wages to skill?)

GET INTO BUSINESS : start a business of something , grow it, reach that amount in 5-6 years (coz doing business is the real deal and only way to get lots of money in black/white)

Which do you think is the most accurate/realistic?

When you describe to the business owner as a dev that this is a bad idea but they want it anyways so you just go on and dev it. Then 1 month into dev hell thinking about hanging your self for poor choices they go “This future is too difficult for the customer to understand and its not going to work”. Do you say i told you so or do you hang him with a mouse cable?
