My dumb CEO just hired an even dumber CTO. The new CTO asked me the following questions...
1. What is GitHub?
2. What is JSON?
3. What’s an array?
4. What is Get and what is Post?
5. When an iPhone is offline, can it call an API on our server to tell us it’s offline?
6. I know you’ve spent 11 month the writing this backend in PHP but can you change it to Java now?
Me: Why?
Dumb CTO: Because it’s better.
Me: How?
Dumb CTO: because it is.
7. I know you’ve started to rewrite this codebase I Java but can you convert it to Node.JS now?
Me: Why?
Dumb CTO: Because Facebook uses it.
8. What is MySQL? Why aren’t you using a database instead?
9. What does NULL mean?
Somehow, I doubt that asshole is remotely qualified for the job.

Going through Master Card API docs to see how to integrate it, saw that they have sample code, checked Java sample code and found this:
String data = MessageFormat.format(
"'{'\"apiOperation\":{0},"
+ "\"sourceOfFunds\":'{'\"type\":{1},\"provided\":'{'\"card\":'{'\"numbe\":{2},"
+ "\"expiry\":'{'\"month\":{3}, \"year\":{4}'}',\"securityCode\":{5}'}}}',"
+ "\"order\":'{'\"reference\":{6}'}',"
+ "\"transaction\":'{'\"amount\":{7},\"currency\":{8},\"reference\":{9},\"targetTransactionId\":{10}'}'," + "\"customer\":'{'\"ipAddress\":{11}'}}'",
apiOperation,
sourceOfFundsType,
cardNumber,
cardExpiryMonth,
cardExpiryYear,
cardSecurityCode,
orderReference,
transactionAmount,
transactionCurrency,
transactionReference,
targetTransactionId,
customerIpAddress );
FOR FUCK SAKE what happened to JSONObject (for Android) class, I'm sure it is a waaaay better solution than that mess ...
And from Oracle:
JsonObject value = Json.createObjectBuilder()
.add("firstName", "John")
.add("lastName", "Smith")
.add("age", 25)
.build();
I guess that is a cleaner understandable solution than what master card has.8 -
I've been so pissed off so many times, I thought I should divide them into categories.
- Pissed off at a fellow dev: I told him to use a constant instead of a hardcoded number.
He changed this: obj.method(3);
to this:
public static final int three = 3;
obj.method(three);
- Pissed off at management: I once got a $10 yearly raise.
- Pissed off at a client: They rejected our design proposal because the text was in spanish and they didn't speak spanish. It was lorem ipsum text.
- Pissed off at code: I once had to refactor a 500 line legacy jsp script with HTML, CSS, JS and Java completely intertwined.
- Pissed off at Twitter: They changed their API the day of our go-live, breaking all of their widgets, forcing us to move the go-live date and making me work an additional 8 hours after a week with almost no breaks.
- Pissed off at travel and logistics: They sent me to a hotel in Mexico City 2.5 hours away from the client's office.
Fun times...1 -
I feel like I was very productive today. At last, I found myself a nice dark theme for NetBeans based on IntelliJ darcula theme. I also found a perfect Java API 8 SE class for date manipulation called LocalDate.4

A friend came to me whether i want to do a project on c++(someone asked him to find a c++ guy).
Me needing money didn’t refuse. Even though i am a Java developer with 0 skills on c++, but wanted to give it a try.
So project started, and it was about a plugin for rhinoceros app(3d graphics app).
The plugin was simple, had some views and some services to upload a file into s3 and some api calls, not something complex..
So i ended up working on the project together with my friend(web dev).
So long story short, we had a lot of issues, but considering we both had no knowledge on c++, we were really lucky to finish the product almost on time(3 days after).
Did no memory management even though i’ve read that we have to do that by our selfs and that c++ doesn’t have garbage collector.
But the plugin worked great even without garbage collector.
Had a lot issues with string manipulation, which almost drive me crazy.
PS: did a post here before taking the project, to ask whether it is a good idea to take the project or not, had some positive and some negative replies, but i deleted the post since i thought i was breaking the NDA i signed 😂😂
PS2: just finished OCAJP 8 last week with a great score😃6 -
So I recently finished a rewrite of a website that processes donations for nonprofits. Once it was complete, I would migrate all the data from the old system to the new system. This involved iterating through every transaction in the database and making a cURL request to the new system's API. A rough calculation yielded 16 hours of migration time.
The first hour or two of the migration (where it was creating users) was fine, no issues. But once it got to the transaction part, the API server would start using more and more RAM. Eventually (30 minutes), it would start doing OOMs and the such. For a while, I just assumed the issue was a lack of RAM so I upgraded the server to 16 GB of RAM.
Running the script again, it would approach the 7 GiB mark and be maxing out all 8 CPUs. At this point, I assumed there was a memory leak somewhere and the garbage collector was doing it's best to free up anything it could find. I scanned my code time and time again, but there was no place I was storing any strong references to anything!
At this point, I just sort of gave up. Every 30 minutes, I would restart the server to fix the RAM and CPU issue. And all was fine. But then there was this one time where I tried to kill it, but I go the error: "fork failed: resource temporarily unavailable". Up until this point, I believed this was simply a lack of memory...but none of my SWAP was in use! And I had 4 GiB of cached stuff!
Now this made me really confused. So I did one search on the Internet and apparently this can be caused by many things: a lack of file descriptors or even too many threads. So I did some digging, and apparently my app was using over 31 thousands threads!!!!! WTF!
I did some more digging, and as it turns out, I never called close() on my network objects. Thus leaving ~30 new "worker" threads per iteration of the migration script. Thanks Java, if only finalize() was utilized properly.1 -
i am feeling angry and frustrated. not sure if it's a person ,or codebase or this bloody job. i have been into the company for 8 months and i feel like someone taking a lot of load while not getting enough team support to do it or any appreciation if i do it right.
i am not a senior by designation, but i do think my manager and my seniors have got their work easy when they see my work . like for eg, if on first release, they told me that i have to update unit tests and documentation, then on every subsequent release i did them by default and mentioning that with a small tick .
but they sure as hell don't make my work easy for me. their codebase is shitty and they don't give me KT, rather expect me to read everything on my own, understand on my own and then do everything on my own, then raise a pr , then merge that pr (once reviewed) , then create a release, then update the docs and finally publish the release and send the notification to the team
well fine, as a beginner dev, i think that's a good exercise, but if not in the coding step, their intervention would be needed in other steps like reviewing merging and releasing. but for those steps they again cause unnecessary delay. my senior is so shitty guy, he will just reply to any of my message after 2-3 hours
and his pr review process is also frustrating. he will keep me on call while reviewing each and every file of my pr and then suggest changes. that's good i guess, but why tf do you need to suggest something every fucking time? if i am doing such a shitty coding that you want me to redo some approach that i thought was correct , why don't you intervene beforehand? when i was messaging you for advice and when you ignored me for 3 hours? another eg : check my comment on root's rant https://devrant.com/rants/5845126/ (am talking about my tl there but he's also similar)
the tasks they give are also very frustrating. i am an android dev by profession, my previous company was a b2c edtech app that used kotlin, java11, a proper hierarchy and other latest Android advancements.
this company's main Android product is a java sdk that other android apps uses. the java code is verbose , repetitive and with a messed up architecture. for one api, the client is able to attach a listener to some service that is 4 layers down the hierarchy , while got other api, the client provides a listener which is kept as a weak reference while internal listeners come back with the values and update this weak reference . neither my team lead nor my seniors have been able to answer about logic for seperation among various files/classes/internal classes and unnecessary division of code makes me puke.
so by now you might have an idea of my situation: ugly codebase, unavailable/ignorant codeowners (my sr and TL) and tight deadlines.
but i haven't told you about the tasks, coz they get even more shittier
- in addition to adding features/ maintaining this horrible codebase , i would sometimes get task to fix queries by client . note that we have tons of customer representatives that would easily get those stupid queries resolced if they did their job correctly
- we also have hybrid and 3rd party sdks like react, flutter etc in total 7 hybrid sdks which uses this Android library as a dependency and have a wrapper written on its public facing apis in an equally horrible code style. that i have to maintain. i did not got much time/kt to learn these techs, but once my sr. half heartedly explained the code and now every thing about those awful sdls is my responsibility. thank god they don't give me the ios and web SDK too
- the worst is the shitty user side docs. I don't know what shit is going there, but we got like 4 people in the docs team and they are supposed to maintain the documentation of sdk, client side. however they have rasied 20 tickets about 20 pages for me to add more stuff there. like what are you guys supposed to do? we create the changelog, release notes , comments in pr , comments in codebase , test cases, test scenarios, fucking working sample apps and their code bases... then why tf are we supposed to do the documentation on an html based website too?? can't you just have a basic knowledge of running the sample, reading the docs and understand what is going around? do i need to be a master of english too in addition to being a frustrated coder?
just.... fml
