Firebase never made sense to me. I know nothing about web dev though. It seems like you are handing over your project to some nebulous entity and they can change the deal, stop updating or patching or raise the price. It seems better to simply build the whole project yourself.
Does anyone know what antenna that is? Ive been meaning to make or buy an extremelely powerful (sensitive?) Wifi antenna for years now. I know nothing about antennas or radios and one of these days ill have to change that!
I thought it was funny how video previews and superchats have been around forever in porn. Google lens made me genuinely excited. The most important bit was also the shortest: designing nets with nets. I wonder what nn experts think of that little sidenote.
I will expound, these types of measures to "protect the people" are absurd, farcical, and generally do way more harm than good, causing ridiculous friction in the market that helps no one. This tariff only helps the inefficient.
Its because math is used as test material. Thats all it is in american educations and many others i might add. Its a fucking crime. All of science and almost everying else is treated similarly. They build tests into the material you are to learn. At the end of the day you get a monstrosity. I say that if we are going to try to hide iq tests inside the material then we should have no qualms about simply giving everyone iq tests separately from learning material. Yes there are flaws with that proposal but it would still be better than what we have now where all of the material is molested. Imagine if people actually got a thorough education. No more grtting to the job only to learn that they didnt teach you what you need to know. In computer science this problem is fucking atrocious.
Jesus i hate this style of journalism. S/he goes on and on with useless descriptions of what the room looked like and tries to make a novel of the fucking thing. Horrible.
Why were they going after 1password filevaults? I assume 1password is like keypass, where all your passwords are in an encrypted file? How could they decrypt all those files? Or do they assume people use weak passwords?
If used for anything substantial, such as an ebike that goes fast or up slight grades, this motor would simply melt. Its really cool though. A lot of ebikers fool around with liquid cooling but ive never seen it pulled off. This guy could take advantage of the 3d printing method to add liquid cooling and besides being really cool it might allow the motor to do useful work without melting.
It must be very application specific what kind of air cooling you get? If you have a motor enclosed on an e-bike vs. if you have it naked on some kind of aircraft with a propeller blowing on it must make a huge difference?
A problem I guess with plastic is that it doesn't conduct the heat to the outside like a metal construction would, so it will always dissipate less than metal, regardless of environment? That issue is still there if you add liquid cooling - the plastic won't transfer heat to the cooling medium either.
What's the state of the art in high-temperature resistant 3D-printed materials?
They print titanium and ceramics ive heard. Must be expensive. I would be very interested in seeung someone print a ceramic motor, beefed up to account for poor strength of ceramics. Yes most hub motors are closed but its very common for people to drill holes in the walls of the motor to get some air cooling. Less common is actually filling the closed hub motor with oil -- ive seen blog posts where people report that if you get that to work it does wonders for cooling. But there are huge problems with it, mainly related to accounting for the expansion of the oil as it heats up. Even less common is real liquid cooling where coolant is channelled down the axle and into the stator. Doing it with plastuc would mean having some metal inserts for heat conduction to the coils.
Not really, like most micro particle or fiber filaments the thermoplastic resin is the weak part.
Any thermoplastic extruded filament that does not require secondary treatment is going to be heat sensitive.
The filaments that are not heat sensitive are either ones that require substantial heat to extrude in the first place or at then chemically treated to not be thermoplastics anymore.
If you think about this way it's simple, the melting point and the thermoplastic point of the end product needs to be substantially higher than it's operating temperature this cannot be done without additional treatment or using a process other than thermal extrusion.
Resins that use chemicals or light to harden are can have thermal resistance properties, metals and other materials that are extruded or bonded at very high temperatures are also resistant to relatively high operating temperatures.
Makes sense, Although I was trying to infer that the carbon material would transfer the head through the object better. Which would make using a liquid cooling channel useful. As opposed to just outright higher thermal operation.
But this is only evidenced from the carbon on my XPS laptop becoming untouchable in full-sun and much of the base heating evenly from the processor.
Some guys from Berlin demoed heat resistant printer filament at the Make Munich. After printing, you put it in the oven and then its heat resistant up to ???°C.
A while ago i tried dual booting elementaryos on my windows machine. Steam and counter strike global offensive work just fine. Half life 2 as well. After realizing that i could play cs on eos, i simply had no reason to go back to windows.
