Okay! How do I use this shit!? Anonymous 07/19/2020 (Sun) 23:26:18 No. 1171 [Reply] [Last]
A time ago my brother brought me a SMD Rework Station, to help me on repair our things. But, HOLY SHIT! WHY IS SO HARD?! Everytime I tried ended up with me burning the component or the board, or both. I tried to decrease the air or the temperature but the result end being the same. I know that I'm doing something wrong, but I don't know what is.

>>1172 How much time I need to remove a SMD? It doesn't hurt the component?
usually like 20-30 seconds if you have a good setup. if you don't have a good setup you should do a ghetto preheat by waving the gun around quickly all over the board. like I said, you want the board to be nice and warm (~70-80C) all over so you won't waste as much of your heat into the big copper pours on the inner layers. if you just jam the heat on full blast to a cold board you can end up with the top of the component scorched at ~400C while the solder is still only like 170C (SAC305 needs 220C-245C to melt) on the connections to the board since the heat just keeps bleeding away into the copper. you will learn to hate ground planes with a fiery passion, seriously fuck emc compliance and all that garbage, fuck controlled impedance, fuck dcr. components are typically packaged in some sort of plastic package. if you solder it fast enough you can get the terminations up to 220/245C while keeping the silicon on the inside under it's critical temperature. like 140-160C or some shit maybe, forget exactly at the moment and it varies per-component.
>>1171 Hi I work in a smartphone repair shop. Depending on the size of the board, sometimes you need to hold the hot air a FEW MINUTES on the board just to heat it up enough to melt the solder. and don't worry about overheating; if the solder isn't melted yet, that means the board hasn't even reached solder's melting point temperature. I suggest setting your hot air temperature around 350C, watching tutorials on youtube and PRACTICING on garbage dead PCBs.

Windows vs Linux Anonymous 02/01/2020 (Sat) 10:15:05 No. 718 [Reply] [Last]
Base up, W10 is superior. Easier, more efficient, better support and compatibility, less hassle. But for the die hards, why is Linux better to you?

>>718 I used to run Wingblows 8 which was okay-ish early on but later would update rape me, constantly crash, and lag from all the shitty spyware that I kept uninstalling but the OS would reinstall shit on boot like Skype and MSM. I'm not the most tech savy guy just competent enough to not be borderline retarded and Jewbuntu hasn't a hiccup once on any of my computers so far, infact it actually runs some of my games even better than Wingblows. I like the fact that if I delete a shitty bloatware program it stays deleted.\ Also Bill Gates is a glow in the dark globalist nigger. >>869 Based and practical user pilled.
apples and oranges, linux is objectively superior in most metrics, there are only a handful of applications that don't run on linux and then Windows is best for gaming, once those gaps close though there will be little reason for users to use Windows
Easier makes it so any chimp can use it. Only chads are smart enough to use Linux.
Is Mint a good starting OS? I want to blow outta Winblows. It used to be based, but Gates has now become a jew.

Why aren't you using a microkernel hypervisor? Anonymous 04/20/2020 (Mon) 08:01:09 No. 873 [Reply] [Last]
SculptOS (Genode Framework+seL4) is a secure microkernel operating system that can easily be used to run virtual machines. It supports a variety of real hardware including Intel WLAN and iGPUs. It's less than 30MB and boots almost instantly, and even has a basic GUI built in. https://genode.org
2 posts omitted.
>>873 You literally give z e r o evidence to back up your claims.
Having a smaller kernel would certiantly make it faster, but how would that make it more "secure" and in what way? Not to mention you would have to have a much smaller library of call commands to mantain the kernel's micro status; thus reducing usability and compadability by alot. Which I guess would make it more "secure", but that's like saying you're secure against being robbed because you can't leave the house. Why not just use base Unix if we are going this dinosaur? Why even have a GUI? We can make it even "faster" without one.

I made a bunch of posts on rikchan about old business desktops that I will copy here. you can get a machine with moderate performance at a very good price-to-performance ratio if you are okay with some of the tradeoffs I will discuss. Perhaps this information will be helpful to my fellow /g/tards.

>16 GiB ram >2 TB hard drive nice, that's worth the 80 on its own. and yeah there's something neat about realizing you can rescue old hardware with SSDs - I'd rather use an 8-year old CPU with an SSD boot drive than a modern CPU on spinning rust. You can get little PCIE cards that will add USB3 ports. I suppose if you are good at networking then saturating a wired gigabit link gives you ~100 MiB/s which is a fair bit better than the 35/15 MiB/sec that USB2 gives you in real-world bandwidth. although, I do notice that about 95% that I am trying to move big batches of files around at home it is either for games or music, none of which are necessarily essential. It's no problem pushing a ~100 KiB source tarball around even over usb2 or even wifi b.
>>862 I plan on upgrading to an i7 2600 soon and eventually 32GB RAM since that's unofficially supported on this model. Unfortunately this machine came with only 4GB DIMMs so I'll have to buy all new RAM. But they're probably compatible with the Core2 shitbox I use as a server that has 6GB right now so that'll get a nice upgrade most likely.
The USFF offerings are most interesting, like ThinkCentre Tiny. They're usually upgradeable, so you can have a really small desktop with a proper CPU and maxed with RAM and storage. Been thinking about getting one for a home server, that, a Rasbperry Pi, or ideally something custom so I can get rid of my shitty WD NAS.
I got some free computers from a local library since they were "broken"; but after doing some fixes they all worked save for one (which I scrapped for parts). I guess throwing them out is cheaper then paying for a compentant I.T guy. This happens more often than you would think, I got a free laptop through this method... all I did was open it up and reseat the fan and apply fresh thermal paste.
>>785 I can't imagine buying one of these... I get them for free all the time, but I work in I.T. I haven't paid for a computer in 20 years... ETA PRIME is always fucking with these and other low cost tech, good channel. https://www.youtube.com/watch?v=V1NpJj9rUMM

BTCsub token Anonymous 05/28/2020 (Thu) 17:57:26 No. 954 [Reply] [Last]
Does anyone know about BTCsub token ? is it a scam or a real deal?
4 posts omitted.
(109.38 KB 702x509 postitNOOOOOOW.png)
I personally don't think it's a scam or a pure pyramid scheme. They are implementing WorkLock-controlled referral plan in order to distribute their tokens economically as they want to avoid paying hefty amounts to FANG corporations and enriching them farther. So referral-based WorkLock smart contract is not their primary business model. They are also implementing a proof-of-asset subprotocol to display cryptoassets under management transparently in realtime. So I can't say it's scam as the 3x14 matrix gets terminated irreversibly at 14th level. You can't grow your network of referrals any farther. Plus their total supply of tokens hardcapped. They can't arbitrarily mint new BTCsub tokens either.
Amazing ! I also came across this and was thinking about investing! This really sheds more light! Seems legit to me!
This is certainly a good investment opportunity as well as a means to expand the capital. Just had small initial query indeed, whether only depositing 1 ETH is the only pre-requisite to enter the investment plan to receive more ETH in return as we refer and get more people on the platform or is there more to it?
I have spoken to BTCsub team on their telegram handle. They will be pushing conversion and data oracles contracts next month to their github repo. But they refused to give me a specific date.
>>954 Neither, it's just noise. And your post is spam.

Red-pill me (and I'm sure others) on Quantum computing. Lets not get left behind in a new computing age.
>>707 It’s a completely meme. Not useful for anything outside of some very niche scientific applications.
>>708 yet
It's just multi-state computing, like using a trinary or larger base. Currently our computers work with little pseudo-switches that are either on or off, 0 or 1. Using multi-state switches you can exponentially increase computing power BUT... it just means a faster computer. It's not like it's going to magically turn into some kind of AI singularity due to inherent mathematical limitations, namely the "curse of dimensionality". Also keep in mind our computers, even quantum computers, currently use a flow of electrons... which means they use mono-dimensional energy. It's possible though to use other energy forms, even biochemical energy forms as well as modulated energy forms, like light wavelengths in order to create photonic processors. And then of course, if you want to go full science fiction you could theoretically create a quantum temporal processor using tachyons. Where a calculation could be performed and then the results of the calculation could be sent back in time by a few nanoseconds. So basically the computer would know the results of a calculation before it even performed it. And the further back in time the weirder it would get. For example if information could be sent back in time by a few seconds it would be possible to create a computer that would know what you want before you even knew you wanted it. Essentially an interface-less computer. The interface would be there, but you wouldn't actually need to use it.

Arch, Gentoo, anything not Ubuntu. Really it's mostly user preference, if you're new to Linux I would recommend Arch over Gentoo. But that's about all. "Secure" is vague, securing your system is mostly up to you and not being stupid. Just avoid shit like Windows or Mac OS which have more security holes than a block of Swiss cheese fucked by a pack of starving sex crazed Nambian children.
