We got a new manager. He has us doing scrum meetings in the morning. He is slightly amused and annoyed that I refer to this time as:
"Software developer bonding time."

The IDE mode is dark, and the code is full of errors.

Mr. Ed says "the end is neigh".

I am stuck in my Vim power armor and cannot get out. Is this a bug?

How deep do you go when trying to find a solution?
I have a need for combinations of items. I have used built in functions in Python for this. When I first used those I wanted to learn how they worked internally. I read through the source and thought that was cool. I don't think I really understood that code very well.
Now I need the same solution in C++. There is not a prebuilt combinations function in C++. There is a prebuilt verion of next_permutation. I can build upon that to make my combinations code. However, I am in the middle of trying to make something work. So I found this nice SO question:
https://stackoverflow.com/questions...
The code I ended up using:
template<class RandIt, class Compare>
bool next_k_permutation(RandIt first, RandIt mid, RandIt last, Compare comp){
std::sort(mid, last, std::bind(comp, std::placeholders::_2, std::placeholders::_1));
return std::next_permutation(first, last, comp);
}

template<class BiDiIt, class Compare>
bool next_combination(BiDiIt first, BiDiIt mid, BiDiIt last, Compare comp)
{
bool result;
do{
result = next_k_permutation(first, mid, last, comp);
}while(std::adjacent_find(first, mid, std::bind(comp, std::placeholders::_2, std::placeholders::_1)) != mid);
return result;
}

I am mostly able to figure out what is going on with the templates. I still am not understanding the basic algo behind permutations.

Our data set is tiny. 4 items max. So efficiency isn't really a big issue here.

How long do you spend learning how it works versus just finding a solution for the task at hand?

In general I need to spend more time learning different kinds of algorithms. So I should probably add permutations to that list of ones to study.

A mind computer interface that acts like an extension of my psyche. Allows information access, tool access, and gets rid of mundane interfaces like keyboard and mouse.

I would like this interface to be non-intrusive with the ability to remove. I would hate for it to mess with my driving. In that case it would be nice if it overlay-ed data for a hud while driving. Like just having the speed be an overlay would be nice.

I wonder if such an interface would make our already lazy mental skills even lazier? Or would it invigorate our learning?

Been playing FO4. Not sure I liked it at first. Now I look forward to blowing NPCs heads off with shotguns, or sniping and watching heads jib. It is also satisfying to blow up kamikaze mutants by shooting the bomb in their hands.

I find the computer hacking to be quite amusing as well. Cause computers and hacking...

I of course modded the hell out of it and added a mod to enable achievements even though its modded. I haven't installed many cheat mods. Mainly just carry limit addons because I like carrying a wagons worth of loot around.

Oh, and automatron robots are op as hell.

Dad: Son, please put a liner in the trash.
Son: Argh, okay... <grumbles and starts>
Dad: Its just a one liner. It doesn't even have to be funny.
Son: <GROAN!> ... I hate you ...

If you are programming in C++ please always return a type from a function as the function prototype return type.

I had to debug some old code that failed to return a boolean on one of its flow paths. It would work on linux in release and debug, would work on windows in debug, and fail on windows in release.

The failure was NOT straightforward at ALL. It would return exit code 3. Then if I added a debug print to the function it would segfault.

Why the hell would popping something extra off the return/call stack not crash more readily? Wth is the point of debug compile if it won't catch shit like this?

I only code as root.
I write sudo code.

boost::signals2::signal<void ()> redSmoke;
boost::signals2::signal<void ()> whiteSmoke;
boost::signals2::signal<void ()> blackSmoke;
boost::signals2::signal<void ()> yellowSmoke;
boost::signals2::signal<void ()> blueSmoke;
boost::signals2::signal<void ()> pinkSmoke;

I am having trouble concentrating.
So I am going to work on expanding instead.

I get the feeling that people who prefer C and dislike C++ just don't like stds.

The default font was different between development and production. The default font was never selected for the application. It has been this way for years. I found and fixed this. Now a huge amount of UI issues are just gone. People are like "Why was this never set?" Internally I am saying "Because they got lucky and never thought about it in the past."

Other people's code...

I got invited to take part in the "senior" games in my town. The person inviting me is in their 80s. They said people in their 50s, 60s, 70s, 80s, and 90s will compete. I told them I am not yet 50. They were oh, okay. I said, I will tell Ed at work though. He could be in them!

Then I told Ed about this. He laughed. Then I said he could be in them. He told me to get out of his office, jokingly. I asked him if he was going to go to HR. He said yes. Then he said it was really funny I got invited.

Ed is great to work with.

Today was a day at work that I felt like I made a significant contribution. It was not a lot of code. Actually it was a difference of 3 characters.

I am developing an industrial server so that my employer can provide access to their machines to enterprise industrial systems. You know, the big boys toys. Probably in fucking java...

Anyway, I am putting this server on an embedded system. So naturally you want to see how much serving a server can serve. In this case the device in more processor starved than memory starved. So I bumped up the speed of the serving from 1000mS to 100mS per sample. This caused the processor to jump from 8% of one core (as read from top) to 70%. Okay, 10x more sampling then 10x approx cpu usage. That is good. I know some basic metrics for a certain amount of data for a couple of different sampling rates.

Now, I realized this really was not that much activity for this processor. I mean, it didn't seem to me that it "took much" to see a large increase of processor usage. So I started wondering about another process on the system that was eating 60 to 70 % all the time. I know it updated a screen that showed some not often needed data from its display among controlling things. Most of the time it will be in a cabinet hidden from the world. I started looking at this code and figured out where the display code was being called.

This is where it gets interesting. I didn't write this code. Another really good programmer I work with wrote this. It also seemed to be pretty standard approach. It had a timer that fired an event every 50mS. This is 20 times per second. So 20 fps if you will. I thought, What would happen if I changed this to 250mS? So I did. It dropped the processor usage to 15%! WTF?! I showed another programmer: WTF?! I showed the guy who wrote it: WTF?! I asked what does it do? He said all it does it update the display. He said: Lets take to 1000mS! I was hesitant, but okay. It dropped to 5%!

What is funny is several people all said: This is running kinda hot. It really shouldn't be this hot.

Don't assume, if you have a hunch, play with it if its safe to do so. You might just shave off 55 to 60 % cpu usage on your system.

So the code I ended up changing: "50" to "1000".

Most of the web stuff I have done in the past have been PHP, Wordpress, cgi, etc. I read about nginx and was very impressed by what it accomplished in the last 20 years. Now I have a desire to play with this tech for fun.

What I want to do:
- create, manage, and launch minecraft servers
- provide a web interface for managing servers (I would like to learn how to make the server use the infrastructure of nginx to be managed like its other services)
- make this packaged so others can use this (probably on github)

I don't know anything about nginx other than it is really really cool, can serve massive amounts of web pages, and can do a whole lot more than that.

Question:
Is nginx suitable for this? Is this a big learning curve? Will I have fun doing this?

I am currently running a multi-instance minecraft server being managed by a piece of software called Crafty Controller. It is really neat. However, I am finding it buggy. I also see that the next version of this software will be behind a patreon. This is really disappointing. So this is spurring me to consider building something fun for myself, and if useful, for others.

I will most likely do very barebones and inflexible web interface that just gets the job done. I know enough to get by. So I assume I have a large learning curve ahead to do this.

Any advice? Is this going to turn into a large time sink?

So I found these stack overflow questions and thought they were particularly humorous.

https://stackoverflow.com/questions...

The answers were pretty good. But I wanted to actually "break out of an if statement" like the ops asked for. So I created these monstrosities:

I have finally done what I will call a "pro javascript move", but I did this in C++...

QString str("hello");
float offset=0.0;
...
offset = somevalue;
return str + offset;

This printed out "hello[]". Where [] is some unknown character box.

No warnings at all. It just found a conversion function and did it.

So I finally got something to allow me to pipe my network over ssh when I need it.
alias mcserversshproxy='ssh -p <port> -N -D localhost:9999 <user@server>'

I can now use the internal webpage in my network by configuring a profile in firefox as a proxy. Kind of slick!

This tutorial, despite its flaws, helped me work this out:

So I a using the ssh installed with git on Windows.
I am trying to forward a port on my internal network server which is also my ssh server. I have exposed my network server on a forwarded port on my router. When I try to forward using this command I get a connection reset on my web service on my server.

ssh -nNT -p <port on router> -L 8000:192.168.0.22:8000 <sshuser@router>

I can log into ssh normally. So I am really confused. the 192.x.x.x address is the internal ip of the server. On a browser I try to connect to the 127.0.0.1:8000. It says the connection is reset. I assume it is being refused. So it tries to connect to something, but it fails.

I can connect to the web server from within the internal network via 192.168.0.22:8000. Really confused as to what is failing here.

So I think I have answered this, but here goes.
I have ddns service I need to update periodically. I chose once every 5 minutes. I am using this command:
/usr/bin/wget -O /dev/null -o /dev/null <webcall url>
I have it running every 5 minutes in a cronjob. I checked and wget is using port 443 to connect to my webcall url which is https. I am assuming this is hiding the details of the url. Is this true? Also, I don't like that the cronjob is sending the whole command to syslog. Is there a way to prevent it from syslogging this? I would rather keep the details of the url hidden as much as possible. I am the only user on the server, but am curious if there is a way.

So questions are:
1. Is wget hiding the details of the url from prying eyes? It is using port 443 for https.
2. Cannot I not log the cronjob command in syslog? I supose I could create a script that hides this.

If I ever get asked to write code in C for a contract again. I am going to use the llvm C++ to C compiler. Then deliver the machine generated C code to them.

Saw a discussion on object lifetimes in C++.
I was wondering: Is this an object existential rumination?
What does it mean for an object to exist if it can live and die?

I bought this to serve Minecraft:
HP Z420 Workstation E5-1650 V2 Six Core 3.5Ghz 32GB 256GB SSD Quadro 600 Win 10

Adding 1TB 870 Evo for Linux. Gonna default boot to Linux. I am hoping to serve up a few instances of various modpacks. Minecraft is single thread so I wanted decent per core performance.

All total I spent about $450.

Don't know if anyone posted this, but I did a random search for "terahertz computer".

I found 2 interesting things:
https://extremetech.com/extreme/...
https://sciencedaily.com/releases/...

So DARPA actually built a terahertz chip and some people in the middle east have developed tech for a light based chip.

I don't know about you, but I so WANT a terahertz capable CPU.
