I lose motivation to do anything today.
I don't want to watch movie , I don't want to eat , am I facing a different form of burnout or am I depressed?
I hope I will be feeling better tomorrow.7
I wanted to know what is the worst mistake you make on database.
I have actually implements the logic of token access control on database and not on business logic layer.
The database have a login procedure which accept username and password. That login procedure actually hash the password and try to authenticate user.
If it is a correct user , it generate a token. In other to use other procedure on database , you must provide a token. By using that token , the procedure know who is it and what permission is granted to that user.4
Woke up in the middle of the night, got an idea , write an idea into notebook , went back to sleep.5
I got a fuzzy understanding of differences between Platform as a Service (PaaS) , Infrastructure as a Service (IaaS), and Software as a Service (SaaS).
I wanted you guy to clarify it for me. For me
IaaS = You choose how much RAM , CPU , Storage you wanted and the provider create the OS for you by virtualization technology and you can do whatever you want on that OS
PaaS = The provider said here is a services (database , docker ,---etc) we offer to help you develop your own software. You use the service we offer and we charge you by how much you use our service.
SaaS = The provider said here is the complete software. You can just use the software and we charge you how many request you send or how many data you store,--etc.
Is the differences between IaaS and dedicated server is that in IaaS you may share the server with other client by virtualization and dedicated server give you the whole server?13
I got to create the data platform with Azure Data Factory. I am new to data platform.
Any advise on what to look out for?
Could you guy please tell me if you know any good use case I can look at or any obvious pitfall which drain all the credit and so on?
I just a vague idea of what Azure data factory can do.4
Stupid windows update. You really want to update at the most inconvenient time.
I do manual update on my current computer but I boot up the old computer which I have store away. Remind me the reasons why I hate windows update and to disable automatic update.3
Rest In Peace my Hermes E2 mechanical keyboard. I have been using it for about 4 year and today the shift key on the left side of the keyboard broke.
I think the shift key is physically broken since I already try to clean the keyboard but it isn't working anymore.
The keyboard should still be workable for normal user but programming with that keyboard is a hell.
You only notice how much left shift key is important for programming when you try to program with alternative (right shift key)15
I got the question about the ownership of the technology.
I understand If I develop my own technology outside of company work hour and without using company resource,I own the technology. Let call this technology "X".
If the company want me to work on "X" during company hour with company resource to profit off it, do I still own "X"?12
The heck is wrong with the testing framework. I can obviously see that it a correct value why doesn't the test case pass.
REQUIRE( positive==static_cast<double>(0.7352941176) )
0.7352941176 == 0.7352941176
test cases: 1 | 1 failed
assertions: 1 | 1 failed10
I went to an interview and they say they will call me within 2 week if I pass the first round of interview.
They don't call me so I assume I fail the interview and life went on.
I received the call today said I pass the first interview and if I wanted to come for second interview. My first thought is Fuck Off.
My acquaintance work for that company and we have a frank conversation. What is going on is that they are overwork and the other department complain that they don't have output from IT department.
When they ask IT department why don't produce output, head of IT department said they don't have enough people. HR department reluctantly allow them to hire more people and they phone me. My acquaintance apologize for the move that their company make. My acquaintance also said that he/she will also pass my decision to their department head.
I have meet everyone is that IT department whom I am going to work with and I like them. They are not only knowledgeable but also a nice person. More importantly they value the quality of work. They are the kind of person I like working with.
What I don't like is their HR department and they only call me when their departments work stale.
Here is my problem, I like the people I am going to work with but I don't like the company that they think I am kind of "backup". The company is the reputable company and it will be easier for me to find other job if I decided to quit and apply for other job.
I know the price range that they are willing to hire me due to first interview and the probing question I asked.
I was thinking of asking for salary outside their price range and think how it goes. If they are willing to hire me despite the ridiculous salary I asked , I may tolerant to work with them.
How do you think I should handle the situation?2
I need to add new feature into the program which I wrote years ago so I start digging up the source code. The project is written in a language which I no longer code in.
That code is really poorly written with most of them don't have tests. I also find out that previous self is really a genius since he can keep track of huge project with almost no documentation.
To make matter worst, there are unused components (class,feature) in the source code. "Current me" have a policy of "just adding only a feature you need and remove unused feature" but it seem the "previous me" don't agree with the "current me".
The previous me also have the habit of using writing insane logic. I can remember what particular class and methods is doing but I can't figure out the details.
For example one method only have 5 line of code but it is very hard to figure out what those do.
The saving grace is that he know the important for method signature and using immutable data structure everywhere.
I was under the influence of caffeine and have a constant sleep deprivation at the time (only sleeping about 4 hour every day) so I can't blame him too hard.
I can't blame him too hard, right?
Could someone invent a time machine already? Invent time machine not to save the world but to save the developers from himself.5
I am thinking of how I can make data upload reliable. I am sure that I am making it more complex as it could be and I need some pointer.
My goal is to have a pause/resume feature in file uploading.
Here is how it would work.
In order to start uploading , you give the server
1) File Name
2) Folder path you want to upload it to
3) Checksum of the file
Here the server will check whether you can upload it to a folder, whether the file have been previously uploaded (by file name and checksum)
If you could actually upload to the folder , server will return "unique file token" , "folder path" , "unique byte token". Let call it init_upload().
The client will use "unique file token" (to identify the file) , folder path (to know where to upload it to) , "unique byte token" and byte (data which to actually upload). Let call this operation data_upload().
If the operation is actually complete , server will return new "unique byte token"
Internally it will actually work like this.Let say we want to upload "file.mp3", when the client call init_upload() it will create
file.mp3 and unique_byte_token.file.mp3.
When the client upload data first time , it will append data to unique_byte_token.file.mp3.
When the client upload data second time , it will check whether the "byte token" that client put is the same as previous "unique_byte_token". If it is same ,
1) we move the data from unique_byte_token.file.mp3 to file.mp3
2) Delete unique_byte_token.file.mp3
3) Create new unique_byte_token.file.mp3
4) Append data to unique_byte_token.file.mp3
The reason I am using "byte token" is because I want to check whether previous upload is actually success.
Let say we need to call 50 part of data_upload() will put 49 part to file.mp3 and 1 part to byte_token.file.mp3.
Finally the client need to call data_upload_complete() which will
1) Put reminding 1 part to file.mp3
2) Remove byte_token.file.mp3 as cleanup6
I was watching the movie and there is a confession scene with a sunset. I thought wow , it's look nice and just realize that it was not a sunset scene, just my blue light filter turning on at that exact moment.

I have a Successful error.5
I couldn't be the only one who thought of teaching ape how to make fire using stone and releasing them into the wild to accelerate their evolution.
Think about having non-human conversation partner we can debate with. The new kind of view they will bring to existing and future due to their sense (different from us)
And then I remember they will likely be bully due to species-sim because we cannot even solve our racism issue. Maybe it will solve the racism issue or spread more fire due to their presence.1
I had been waiting for a hour to finish compiling and it show me the output above.
By looking at the prototypes and technical ideas which I fail to implements due to various reason , I got an idea.
I got an idea to have a kind of grave yard where people can bury their fail prototype and technical ideas and other people can dug them for inspiration or profits.
As the saying goes "One man trash is another man treasure."
I hope this idea of making a grave yard will not be "an actual fail idea"5
Is sleeping on your desk an actual thing which happen or it is a misconception provided by movies?
I have never slept on my desk no matter how tired I am (I had done a week coding marathon) .I always wrap myself with fluffy blanket when sleeping.12
Sometime I want to name a library "ABC" or "XYZ" just to make a heck out of it.And make it popular enough just for confusion. So they will be like the "ABC" here , is that a placeholder or a library name?6
A person who just starting out ask me about git.
I explain what is "init" , "remote" , "add" , "committing" everything was going well until vim happen.
I just refer him to some beginner friendly tutorial about git and give him a link to git client tool.
How do you guy learn about git? When I stop to think about it git have lot of features.9
I am interested in how you guy discover devrant.
Does someone refer devrant to you or does your feeling explode and you finally found devrant?
As for me someone posted a link on Discord.22
I decided to delete Apache Zookeeper on my Windows system but I cannot delete
It should be easy to delete but Windows said it cannot delete the file. I try to delete using command prompt but it said access denied.14
I been doing a online course and they provide a exercise to do in Jupyter notebook.
I notice that the exercise they wanted us to do this time is too complex. After finishing the exercise I submit it for review.
I thought I am doing an exercise but I had actually done an assignment and submit it :(
Lucky I pass that assignment. It is the worst misunderstanding I have done during my student life.
