I absolutely HATE "web developers" who call you in to fix their FooBar'd mess, yet can't stop themselves from dictating what you should and shouldn't do, especially when they have no idea what they're doing.

So I get called in to a job improving the performance of a Magento site (and let's just say I have no love for Magento for a number of reasons) because this "developer" enabled Redis and expected everything to be lightning fast. Maybe he thought "Redis" was the name of a magical sorcerer living in the server. A master conjurer capable of weaving mystical time-altering spells to inexplicably improve the performance. Who knows?

This guy claims he spent "months" trying to figure out why the website couldn't load faster than 7 seconds at best, and his employer is demanding a resolution so he stops losing conversions. I usually try to avoid Magento because of all the headaches that come with it, but I figured "sure, why not?" I mean, he built the website less than a year ago, so how bad can it really be? Well...let's see how fast you all can facepalm:

1.) The website was built brand new on Magento 1.9.2.4...what? I mean, if this were built a few years back, that would be a different story, but building a fresh Magento website in 2017 in 1.x? I asked him why he did that...his answer absolutely floored me: "because PHP 5.5 was the best choice at the time for speed and performance..." What?!

2.) The ONLY optimization done on the website was Redis cache being enabled. No merged CSS/JS, no use of a CDN, no image optimization, no gzip, no expires rules. Just Redis...

3.) Now to say the website was poorly coded was an understatement. This wasn't the worst coding I've seen, but it was far from acceptable. There was no organization whatsoever. Templates and skin assets are being called from across 12 different locations on the server, making tracking down and finding a snippet to fix downright annoying.

But not only that, the home page itself had 83 custom database queries to load the products on the page. He said this was so he could load products from several different categories and custom tables to show on the page. I asked him why he didn't just call a few join queries, and he had no idea what I was talking about.

4.) Almost every image on the website was a .PNG file, 2000x2000 px and lossless. The home page alone was 22MB just from images.

There were several other issues, but those 4 should be enough to paint a good picture. The client wanted this all done in a week for less than $500. We laughed. But we agreed on the price only because of a long relationship and because they have some referrals they got us in the door with. But we told them it would get done on our time, not theirs. So I copied the website to our server as a test bed and got to work.

After numerous hours of bug fixes, recoding queries, disabling Redis and opting for higher innodb cache (more on that later), image optimization, js/css/html combining, render-unblocking and minification, lazyloading images tweaking Magento to work with PHP7, installing OpCache and setting up basic htaccess optimizations, we smash the loading time down to 1.2 seconds total, and most of that time was for external JavaScript plugins deemed "necessary". Time to First Byte went from a staggering 2.2 seconds to about 45ms. Needless to say, we kicked its ass.

So I show their developer the changes and he's stunned. He says he'll tell the hosting provider create a new server set up to migrate the optimized site over and cut over to, because taking the live website down for maintenance for even an hour or two in the middle of the night is "unacceptable".

So trying to be cool about it, I tell him I'd be happy to configure the server to the exact specifications needed. He says "we can't do that". I look at him confused. "What do you mean we 'can't'?" He tells me that even though this is a dedicated server, the provider doesn't allow any access other than a jailed shell account and cPanel access. What?! This is a company averaging 3 million+ per year in revenue. Why don't they have an IT manager overseeing everything? Apparently for them, they're too cheap for that, so they went with a "managed dedicated server", "managed" apparently meaning "you only get to use it like a shared host".

So after countless phone calls arguing with the hosting provider, they agree to make our changes. Then the client's developer starts getting nasty out of nowhere. He says my optimizations are not acceptable because I'm not using Redis cache, and now the client is threatening to walk away without paying us.

So I guess the overall message from this rant is not so much about the situation, but the developer and countless others like him that are clueless, but try to speak from a position of authority.

If we as developers don't stop challenging each other in a measuring contest and learn to let go when we need help, we can get a lot more done and prevent losing clients. </rant>

Worst thing you've seen another dev do? Long one, but has a happy ending.

Classic 'Dev deploys to production at 5:00PM on a Friday, and goes home.' story.

The web department was managed under the the Marketing department, so they were not required to adhere to any type of coding standards and for months we fought with them on logging. Pre-Splunk, we rolled our own logging/alerting solution and they hated being the #1 reason for phone calls/texts/emails every night.

Wanting to "get it done", 'Tony' decided to bypass the default logging and send himself an email if an exception occurred in his code.

At 5:00PM on a Friday, deploys, goes home.

Around 11:00AM on Sunday (a lot folks are still in church at this time), the VP of IS gets a call from the CEO (who does not go to church) about unable to log into his email. VP has to leave church..drive home and find out he cannot remote access the exchange server. He starts making other phone calls..forcing the entire networking department to drive in and get email back up (you can imagine not a group of happy people)

After some network-admin voodoo, by 12:00, they discover/fix the issue (know it was Tony's email that was the problem)

We find out Monday that not only did Tony deploy at 5:00 on a Friday, the deployment wasn't approved, had features no one asked for, wasn't checked into version control, and the exception during checkout cost the company over $50,000 in lost sales.

Was Tony fired? Noooo. The web is our cash cow and Tony was considered a top web developer (and he knew that), Tony decided to blame logging. While in the discovery meeting, Tony told the bosses that it wasn't his fault logging was so buggy and caused so many phone calls/texts/emails every night, if he had been trained properly, this problem could have been avoided.

Well, since I was responsible for logging, I was next in the hot seat.

For almost 30 minutes I listened to every terrible thing I had done to Tony ever since he started. I was a terrible mentor, I was mean, I was degrading, etc..etc.
Me: "Where is this coming from? I barely know Tony. We're not even in the same building. I met him once when he started, maybe saw him a couple of times in meetings."
Andrew: "Aren't you responsible for this logging fiasco?"
Me: "Good Lord no, why am I here?"
Andrew: "I'll rephrase so you'll understand, aren't you are responsible for the proper training of how developers log errors in their code? This disaster is clearly a consequence of your failure. What do you have to say for yourself?"
Me: "Nothing. Developers are responsible for their own choices. Tony made the choice to bypass our logging and send errors to himself, causing Exchange to lockup and losing sales."
Andrew: "A choice he made because he was not properly informed of the consequences? Again, that is a failure in the proper use of logging, and why you are here."
Me: "I'm done with this. Does John know I'm in here? How about you get John and you talk to him like that."
'John' was the department head at the time.
Andrew:"John, have you spoken to Tony?"
John: "Yes, and I'm very sorry and very disappointed. This won't happen again."
Me: "Um...What?"
John: "You know what. Did you even fucking talk to Tony? You just sit in your ivory tower and think your actions don't matter?"
Me: "Whoa!! What are you talking about!? My responsibility for logging stops with the work instructions. After that if Tony decides to do something else, that is on him."
John: "That is not how Tony tells it. He said he's been struggling with your logging system everyday since he's started and you've done nothing to help. This behavior ends today. We're a fucking team. Get off your damn high horse and help the little guy every once in a while."
Me: "I don't know what Tony has been telling you, but I barely know the guy. If he has been having trouble with the one line of code to log, this is the first I've heard of it."
John: "Like I said, this ends today. You are going to come up with a proper training class and learn to get out and talk to other people."

Over the next couple of weeks I become a powerpoint wizard and 'train' anyone/everyone on the proper use of logging. The one line of code to log. One line of code.

A friend 'Scott' sits close to Tony (I mean I do get out and know people) told me that Tony poured out the crocodile tears. Like cried and cried, apologizing, calling me everything but a kitchen sink,...etc. It was so bad, his manager 'Sally' was crying, her boss 'Andrew', was red in the face, when 'John' heard 'Sally' was crying, you can imagine the high levels of alpha-male 'gotta look like I'm protecting the females' hormones flowing.

Took almost another year, Tony released a change on a Friday, went home, web site crashed (losses were in the thousands of $ per minute this time), and Tony was not let back into the building on Monday (one of the best days of my life).

Everyone's asleep.

I'm not tired, and coding sounds like the best thing ever right now. Figured out a solution to that blocking architecture issue, too. So: headphones on, blare Amon Amarth and Disturbed, bring up editor. It's time to work on that side project!

Best night in months.

When I opened my digital agency it was me and my wife as developers, I had no savings and I needed to get long contracts ASAP which luckily I did straight away.

Lovely client, had worked for them before as a consultant so i thought it would be a breeze. Let's just say the project should've been named "Naivete, Scope Creep and Anger: The revenge".

What happened is that when this project was poised to end I naively thought I would be able to close the job, so I started looking for a new full time consultancy gig and found one where I could work from home, and agreed a starting date.

Well, the previous job didn't end because of flaws in my contract the client exploited, leaving me locked in and working full time, for free, for basically as long as he wanted (I learned a lot the hard way at that time) and I had already started the new agreed job. This meant I was now working 2 full time shifts, 16 hours per day.

Then, two support contracts of 2 hours per day were activated, bringing my work load to 20 hours/day.

I did this for 4 months.

The first job was supposed to last one month, and I was locked into it, all others had no end in sight which is a good thing as a freelancer, but not when you are locked into a full time one already. I could've easily done one 8 hours shift and two 2 hours jobs per day, but adding another 8 hours on top of it was insanity.

So I was working 10 hours, and sleeping 2. I had no weekends, didn't know if it was day or night anymore, I was locked in my room, coding like a mad man, making the best out of a terrible situation, but I was mentally destroyed.

I was waking up at 10am, working until 8pm, sleeping 2 hours until 10pm, working until 8am, sleeping 2 hours until 10am, and so on. Kudos to my wife for dealing with account and project management and administration responsibilities while also helping me with small pieces of code along the way, couldn't have survived without the massive amount of understanding she offered.

In the end:

- I forcefully closed the messed up contract job and sent all the work done to another digital agency I met along the way, very competent people, as I still cared about the project.

- I missed a deadline on my other full time contract by 2 days, meaning they missed a presentation for Adobe, of all people, and I lost the job

- The other two support contracts were finished successfully, but as my replies were taking too long they decided not to work with us anymore.

So I lost 4 important clients in the span of 4 months. After that I took a break of one month, slept my troubles away, and looked for a single consultancy full time contract, finding it soon after, and decided I wouldn't have my own clients for a good while.

3 years since then, I still don't have the willpower or the resources to deal with clients of my own and I'm happily trudging along as a consultant, while still having middle of the night nightmare flashbacks to that time.

Coding at night with noises that bring about focus is the best. I use noisli.com

If you've ever tried using Go plugins raise your hand.
If you've ever tried doing plugins in Go, raise your hand.
If you think that the following rant will be interesting, raise your hand.
If you raised your hand, press [Read More]:

This is a tale of pain and sorrow, the sorrow of discovering that what could be a wonderful feature is woefully incomplete, and won't be for a very long time...

Go plugins are a cool feature: dynamically load pre-compiled code, and interact with it in a useful and relatively performant way (e.g. for dynamically extending the capabilities of your program). So far it sounds great, I know right?

Now let me list off some issues (in order of me remembering them):
1. You can't unload them (due to some bs about dlopen), so you need to restart the application...
2. They bundle the stdlib like a regular Go binary, despite the fact that they're meant to be dynamic!
3. #2 wouldn't be so bad if they didn't also require identical versions of all dependencies in both binaries (meaning you'd need to vendor the dependencies, and also hope you are using the right Go version).
4. You need to use -trimpath or everything dies...

All in all, they are broken and no one is rushing to fix it (literally, the Go team said they aren't really supporting it currently...).

So what other options are there for making plugins in Go?

There's the Hashicorp method of using RPC, where you have two separate applications one the plugin, one the plugin server, and they communicate over RPC. I don't like it. Why? Because it feels like a hack, it's not really efficient and it carries a fear of a limitation that I don't like...

Then we come to a somewhat more clever approach: using Lua (or any other scripting language), it's well known, it's what everyone uses (at least in games...). But, it simply is too hard to use, all the Go Lua VMs I could find were simply too hard to set up...

Now we come to the most creative option I've seen yet: WASM. Now you ask "WASM!? But that's a web thing, how are you gonna make that work?" Indeed, my son, it is a web thing, but that doesn't mean I can't use it! Someone made a WASM VM for Go, and the pros are that you can use any WASM supporting language (i.e. any/all of them). Problem inefficient, PITA to use, and also suffers from the same issues that were preventing me from using Lua.

Enter Yaegi, a Go interpreter created by the same guys who made (and named) Traefik. Yes, you heard me right, an INTERPRETER (i.e. like python) so while it's not super performant (and possibly suffering from large inefficiency issues), it's very easy to set up, and it means that my plugins can still be written in Go (yay)! However, don't think this method doesn't have its own issues, there's still the problem of effectively abstracting different types of plugins without requiring too much boilerplate (a hard problem that I'm actively working on, commits coming soon). However, this still feels to be the best option.

As you can see, doing plugins in Go is a very hard problem. In the coming weeks (hopefully), I'm going to (attempt to at least) benchmark all the different options, as well as publish a library that should help make using Yaegi based plugins easier. All of this stuff will go (see what I did there 😉) in a nice blog post that better explains the issues and solutions. But until then I have some coding to do...

Have a good night(/day)!

!rant just a question. Sorry in advance for the long post.

I've been working in IT in Windows infrastructure and networking side of things for my entire career (5years) and recently was hired for a role working with AWS.

We use Macs and we use *nix distros for days. I've only ever dabbled for 'funsies' before with Linux because every previous job I held was a Windows house and f*** all else.

I'm just wondering if anyone here might have some insights as to a great way to learn the Linux environment and to learn it the right way. I'm not the best Windows admin ever and will never claim to be, but I have seen stuff that other people have done that makes me want to swing a brick at someone's head. And I feel that with all of the setup wizards and the "We'll just do it for you." approach that Windows has used since forever it allowed enough wiggle room for people that didn't know what they were doing to f*** sh*t up royally. I'm not familiar enough with Linux to know if this is also a common problem. I know that having literal full-access to every file in your OS can cause a n00b like myself to mess up royal, thus the question about learning Linux the right way.

I vaguely understand the organization of the folders and file structure within Linux, and I know some very basic commands.

sudo rm -rf /*
Just kidding

But All of my co-workers at my new job are like mighty oaks of knowledge while I'm a tiny sapling. And at times I've been intimidated by how little I know, but equally motivated to try and play catch-up.

In addition to all of this, I really want to start learning how to program. I've tried learning multiple times from places like codecademy.com, YouTube tutorials, and codeschool.com but I feel like I'm missing the lesson that explains why to use a certain operation instead of another. Example: if/else in lieu of a switch.

I'm also failing to get the concept of syntax in certain languages I've tried before. Java comes to mind real fast.

The first language I tried teaching myself was C++ from YouTube. I ended up having a fever dream that night about coding and woke up in a cold sweat. Literally, like brain overload or something. I was watching tutorials for like 9 hours straight.

Does anyone know of a training resource that will explain, in terms a 5 year old would understand, what the code is doing and why? I really want to learn but I'm starting to lose steam cause I'm just not getting it.

Thank you in advance for any tips guys and gals. I really appreciate it. Sorry for the ridiculously long questions.

Junior Dev about 18months in my current job and I've got a problem

Started to feel not wanting to code at work, despite working on a greenfield project thats critical and using new tech. I get a little defensive about PR's over stupid small things (PR was once rejected due to auto indentation "not to standard").

Talked with boss (who I get on well with and like) and thinks my problem is I've lost confidence coding. Trys to get more senior Dev to on side to help me out more.

Same senior Dev is really close with other junior on my team - pair on alot of stuff all the time, have lunch and spend free time together, and will work way past working hours just to try and finish something that day (even though it's not due that day).
(Probs working ~60h weeks, where as I'm ~42h and contracted for 37h. I'll work on if I need to but tries to have balance)

Senior and other junior tend to ignore tickets on the board, do the work and then when I pick it up they say "I did that last night". No docs, no PR for me to ask about how it was done (as they merged it themselves). (They have previously completely refactored my branch in the past overnight then not told me atall)

I'm not saying its favouritism here, but I'm not happy with the situation. I feel I can't ask questions as they are always together or they discuss the problem themselves and just give me the answer (not really acknowledging my points). I dont tend to ask for help from this senior Dev now as I don't feel it's worthwhile learning wise for me.

Other people in the team are great but working on other aspects so not a direct one-to-one alignment (others are DB Dev & principal senior dev)

Furthermore I'm wanting to possibly work on full stack web or more architecture stuff, both which are not in my current teams remit (backend up to API).

So - what do I do? Try and remedy the situation in the current team as best as or look for a new teams as cut my losses.

I'm torn between the 2 and I'm unsure how to get out this rut. I feel I need to find a solution to this soon though

(Sorry for the long rant folks)

I have a question about Android dark theme

I've added dark theme support for my application using 2 different themes declared in styles.xml.

On official android developer site:

"In order to support Dark theme, you must set your app's theme (usually found in res/values/styles.xml) to inherit from a DayNight theme"

and this is what I've done. I've also created colors-night.xml to avoid modifying colors that cannot be modified in styles.xml by coding and this works too: when dark mode is activated from device system, colors changes automatically.

At this point, I was wondering which is the best way to implements dark theme: creating 2 different themes, using colors-night (and drawable-night) or a combination of these 2 ways?
