I have a massive assortment of software ideas that I desire to articulate into reality, but I have very little knowledge regarding computer programming. I desire to learn C/C++ as they appear to be most suitable to my needs, and I would like some advice as to where I can begin and what existing software programs/Operating systems will be most useful to me.

Are the books written by Dennis Richie/Bjarne Stoustrup my best bet?

puts("lol! whatever language gets dat rush!");

yeah, C's printf formatting is daunting at first. All you really need to get going though is %s for text, %d for ints, %f for floats, and a newline \n at the end.

printf("%s %d\n", "the universal number is", 42);

So, does an SSD actually make a damned bit of difference *during gameplay* for any popular games? If one doesn't give a shit about boot or load times, is skipping the SSD and going with the classic bigger, cheaper, mechanical hard drive in a gaming rig the way to go?

Depends on your ram space and your setup. I don't think you get a choice on windows, but on GNU/Linux you can have no swap space in which case it makes no difference but you need enough RAM. Can also depend on the game with level loads. Short answer, it makes a difference. A noticeable difference? Depends.

It pretty depends on what type of games you play as you can save money here or there by buying specific parts that will be used heavily in those games. For example, if you like to play games like Total War, you might want to get a Ryzen 5 or 7 as the threading and price will help out immensely. Those games don't really put a dent in your GPU as much as other games. If you want to play FPS' in 4K or whatnot I'd recommend spending more on the GPU and sticking with a modern intel quad core and something like a 1070 or even a 1080 if you can manage.

Another thing. I'd recommend to get a small 80-120 gig SSD to store your OS and other files and go for a 50 buck 1tb hdd for your video games. Most video games will take a lot longer to load as you're moving the data off of the platter but if you have enough RAM to handle the game's cache you're A OK. Honestly anything over 8G is enough in terms of RAM. If you can squeeze it out try getting mid priced memory modules and overclock them just a bit from there. The reason you want 8 gigs or more is because games (and most programs now) often cache the game's files in memory directly as memory is the second fastest thing you can retrieve your delicious bits from (the next up being your CPU's caches).

Web servers/ async programming Anonymous 08/23/2017 (Wed) 15:48:45 [Preview] No. 10881 [Reply] [Last 50 Posts]
I've been practicing network programming lately and was reading about the different web servers, how they work and so on.
I was wondering how Windows and windows based web servers perform compared to Linux since it has no epoll/kqueue. It turned out it has I/O Completion Ports. Then I searched for web server benchmark comparisons but there were no credible ones. Why has nobody compared these products yet?

This one implies that IIS outperforms nginx in every way and if that is true I want to know how it does that.

This one implies that g-wan is the fastest one (obviously, it's their product, therefore isn't a credible source).

That one also shills for IIS, but it's probably fake since the author doesn't mention anything about hardware or server configuration.

So my questions are:
- Does Windows' IOCP perform better than epoll/kqueue and if so - why? And why don't we implement it for *nix?
- Does IIS outperform nginx/apache and if so - how does it do it and is it related to the IOCP?

I cannot find credible sources and I hope someone here has more experience than me.

I don't have enough knowledge about http servers to answer you. But, I don't think performance is the only thing that matters.
And, it's also affected by many other configurations, such as where your cache is being written (this will depend on your disk write speed and your filesystem).
Open source unix-based systems have more flexibility to work with. You can compile linux, for example, to the bare minimum to work with and the resource usage will be trivial. Not like windows, where you can't disable low level stuff and need to have useless memory usage.
Morpheus with rwasa, for example, will give you very good performance:

Or, use NuttX. It's a realtime OS, and has it's on http server on base system:

What is up with dnscrypt-proxy?

Anonymous 03/23/2018 (Fri) 05:59:11 [Preview] No.12514 del
I think they have no more modifications to do... They can't change low-level stuff because it has to be approved by IETF, from what I know.
Are you using OpenNIC servers? Because if you use it in a server that doesn't support dnscrypt the connection will not be encrypted. Also, if you're using Tor, just enable TorDNS and it will already encrypt dns requests.

Anonymous 03/23/2018 (Fri) 20:47:12 [Preview] No.12515 del
Using the Tor bundle, which handles dns itself. At least, I've never seen it leak dns requests. I'm aware that setting up a stand alone Tor relay or router (or a regular browser proxied through Tor, etc.) requires more dns diligence.

I like using Dnscrypt for clearnet stuff, which I still use for certain situations. Not chan browsing, obviously.

If you're curious, I use Bind9(forward and caching mode) -> Dnscrypt.

My real problem here is if people stop running Dnscrypt servers and/or the list of servers stops being updated. The lack of comment about this is alarming. Maybe I'm just looking in the wrong places?

Dnscrypt2 is apparently a thing now, but I'm only keeping an eye on it, not using it. At least not until I hear from the greater community that this is the next thing.

How can you achieve any privacy while using facebook, or smartphone in the first place. I mean, talking about privacy on any mobile device is very very stupid. There is a real problem towards ignorance here. How can anyone promote privacy as a quality of an app, when it's impossible to verify, and when the phone itself must be infected by other apps to the bone?

Too bad, that the market actually take advantage of the laziness to know and research of comfort of peoples, ready to give up their privacy for the compangy "they trust".

About monstruous company that gained trust and is seen as "friend", steam is the perfect exemple.

Has anyone researched, in-depth, the Facebook, et al., "SHARE" inserts put on web content by third parties? That is, the "Like Button" and other social media embedded services.

I remember Stallman pointing out that Facebook is able to collect metrics from these anytime, ANYONE, Facebook user or not, visits a site. For the sake of a basic example, logging the IP while performing the GET request for the "LIKE" icon.

I know the concept makes it possible but there is some heavy Java Script behind all this and would be very curious to understand how exactly all that works.

Mozilla To Build New Browsers That Conform To Internet Censorship


In November of 1737, decades before America officially declared its independence from the king of England, a young Benjamin Franklin published an essay in The Pennsylvania Gazette entitled, “On Freedom of Speech and the Press.” In it, Franklin wrote, “Freedom of speech is a principal pillar of a free government; when this support is taken away, the Constitution of a free society is dissolved, and tyranny is erected on its ruins.” Franklin went on to write, “An evil magistrate entrusted with power to punish for words, would be armed with a weapon the most destructive and terrible.”

Although this was written in an article published more than two and a half centuries ago, Franklin’s words are quite possibly more relevant today than they ever have been. Indeed, there is an ongoing effort by the progressive left and extremists such as George Soros to silence speech that doesn’t align with the liberal agenda. This effort to effectively gut the First Amendment is taking place virtually everywhere you look, from the mainstream media, to Hollywood, to college campuses, and perhaps most frequently, across the Internet.

Recently, the popular Internet web browser Mozilla Firefox announced that it plans on joining the fight against what it considers to be “fake news,” a term that to leftists means nothing more than news that is written by conservatives. Mozilla said that it was “investing in people, programs and projects” in an effort to “disrupt misinformation online.”

The first question that every constitutionalist and liberty-loving American should be asking is as follows: How does Mozilla define “fake news?” Are they only talking about suppressing radical websites such as sites run by white supremacists, or are they talking about any news that comes from conservatives? At the very least, it should worry you that companies like Mozilla are often reluctant to thoroughly define “fake news” – it is highly unlikely that this is unintentional.

Furthermore, what exactly gives Mozilla the right or the authority to determine what is misinformation and what is not? The United States Constitution is the law of the land, and the freedom of speech is an inalienable right from God. The fact that Mozilla thinks it has sweeping authority to select which speech is censored and which speech is not runs contrary to everything that America was founded upon.

With the assault on independent media getting increasingly aggressive, many Internet bloggers and website owners are desperately looking for ways they can continue voicing their opinions without being harassed, suppressed or silenced. If you are one of these people, you may want to consider using “Brave,” a relatively new web browser founded by former Mozilla CEO Brendan Eich.

On its website, Brave states that its goal is “to transform the online ad ecosystem with micropayments and a new revenue-sharing solution to give users and publishers a better deal, where fast, safe browsing is the path to a brighter future for the open web.”
