I really would like to see a cost and cooling breakdown. I just can't see how you can do radiative cooling on the scales required, not to mention hardening.
I thought this was a troll by Elon, now I'm leaning towards not. I don't see how whatever you build being dramatically faster and cheaper to do on land, even 100% grid independent with solar and battery. Even if the launch cost was just fuel, everything else that goes into putting data centers in space dwarfs the cost of 4x solar plus battery.
I'm surprised we have not seen more investment into RISC-V from Chinese firms. I would think they want to decouple from ARM and the west in general as a dependency. Maybe they view the coup of ARM China as having secured ARM for the time being and not as much pressure?
Either way, it's currently hard to be excited about RISC-V ITX boards with performance below that of a RPi5. I can go on AliExpress right now and buy a mini itx board with a Ryzen 9 7845HX for the same price.
I'm surprised we haven't seen more investment from Indian firms. India is really trying to raise their game in the tech economy beyond the services industry. You don't need the most cutting-edge chip fabrication equipment to manufacture these processors.
The Indian government was actually a very early adopter, they had one of the first RISC-V processors that wasn't based on the vanilla Rocket designs, starting back in like 2016 or so. Unfortunately they made some other weird decisions, like not supporting compressed instructions so the chip wasn't compatible with any mainstream Linux distros, and I don't think the project really went anywhere. Although looking at Wikipedia the project seems to still exist.

Why would you think that? ARM is not like x86 CPUs where you get the completed devices as a black box. Chinese silicon customers have access to the full design. I guess it's not completely impossible to hide backdoors at that level but it'd be extremely hard and would be a huge reputational risk if they were found.
They also can't really be locked out of ARM since if push comes to shove, Chinese silicon makers would just keep making chips without a license.
I did catch one vendor using a HAL across a whole SoC product line, a very low-level HAL that sat between SoC hardware registers and kernel drivers. It effectively made the drivers use scrambled register locations on the AHB etc, but if you resolved what the HAL did, the registers matched ARM's UART etc IP. So I figured they were ducking license fees for ARM peripherals.
LoongArch is a weird mix of MIPS and RISC-V. There's not much that would be gained by investing a whole bunch into LoongArch that couldn't also be done to RISC-V, if at all.
Thing about RISC-V is that there are technically no barriers on doing as you see fit, but there's very clearly defined lines where community support isn't guaranteed, like custom extensions or screwing with already ratified extensions.
We actually don't know a lot about the UR-DP1000 chip, while we do know quite a bit about the 3A6000 because of Chips and Cheese. This makes a thorough analysis of the crimes committed within the core architecture of the UR chip more of speculation than a coherent discussion.
But we do know:
1. The UR-DP1000 does not have any Vector instructions
2. UR only has a 4 way OOO design, while the 3A6k is 6 way OOO
3. The cache architecture of the UR is more complicated, with 4 cores sharing 4MB L3 per cluster (2 clusters total), and a 16MB global L4 where the 3A6k doesn't have this
4. The UR chip doesn't have SMT
Everybody sane will want to move away from them, there is nothing chinese specific.
The most performant RISC-V implementations are from the US if I am not too mistaken.
Wonder if that hardware can handle an AMD 9070 XT (resizable bar). If so, we need the steam client to be recompiled for RISC-V and some games... if this RISC-V implementation is performant enough (I wish we would have trashed ELF before...)
Is there an actual U.S. RISC-V CPU that achieves competitive performance? I think the performance leaders are currently based in China.
There's a difference between announcement, offering IP for licensing (so you still have to make your own CPUs), shipping CPUs, and having those CPUs in systems that can actually boot something.
For instance, SiFive in the US, but last time I did check them, their RVA23 CPUs on their workstation boards did not have cache-line size vector instructions (only 128bits aka sse grade I think), RVA23 mandates the same "sweet spot" for a cache line size than on x86_64: 64bytes/512bits.
Yep... but RISC-V large and performant implementations won't access the latest silicon process for a good while... better to push for native support to help.
It's not better architecture so the gain is few pennies more per chip at cost of A LOT of work... work that can't just run Android or much else out of the box.
Isn’t that kind of like saying automated testing (for apps written without testing in mind) isn’t worth it because you have to spend time getting code into a state that is testable?
I do agree that it takes a lot of work to get something usable, and so I think we are a ways off from mainstream risc-v. I do also think there is a lot more value for low power devices like embedded/IoT or instances where you need special hardware. Facebook uses it to make special video transcoding hardware.
Getting the chip stable is one thing. Getting all the various software applications that one uses test their chip is another, and a lot of hardware companies won’t have experience there. Then there is customer code…
One of my consulting customers has been half India, half not for a decade. There is a real push over the last year to wind down the not India half and shift to mostly India.
India based folks cost 50-75% less. I realize that quality India hires would be closer to US rates, but management is ignoring that aspect.
If they're lucky they'll find one solid worker who's going to watch everyone else's hands. I've had one criminally underpaid unofficial[0] tech lead like that. He was herding a team of 11, where like four people at most really cared about the outcome of this project.
[0] Because otherwise a raise would be in order. Can't have that.
I use ACME with Google Public CA for this reason. No one bats an eye at GPCA. Also, their limits are dramatically higher than LE.
Good news for your manual renewal friends, renewals drop to 197 days in February, halving again the year after, halving again until it reaches 47. So they will soon adopt automation, or suffer endless renewal pain.
Yea couldn't install gps, then realized the package manager only had maybe 10% of what most gli.net routers have because of the 'special' chip in this one.
Still a great travel router, but had to buy a BerylAX for what I wanted to do with the usb gps.
ATMs all over are like this. Very annoying. I have to decline conversation all the time. The ATM conversation rate is usually 15-25% markup. No thanks, my bank charges nothing, just passes on the Visa 1% fee for fx.
Great question. Let’s take a deep dive on money. Getting $100 at the right time can be a game-changer! It’s not only a store of value — it’s a means of exchange!
If you had ever purchased a RyanAir ticket you would understand. You get up charged for everything and have to deselect all the up charges at multiple screens. It is their operating model to sell basically free seats, and profit on upsells. Third parties eliminate a large portion of their upsell pipeline.
Ryanair is cheap, they charge extra for everything. But the tradeoff is you get where you are going for cheap if you avoid all the extras, including bottled water.
The funny part is how most OTAs are pretty awful with addons themselves. I know for a fact that certain OTAs will sell tickets at a loss hoping you trip up on one of their checkboxes, like the 15€ automatic checkin service many offer.
I just now booked a ticket on gotogate, paid 80 euro and received a receipt from ITA airways for 120 euro. They apparently lost 40 euro on this sale, I only had to click "no" on about 18 questions.
I feel that a lot of OTAs will just not refund you when a flight is cancelled, especially if it's not one of the more reputable ones. Is that what happened here? How did you fix it?
In my case in 2020 I had to request my refund via PayPal for Vayama
This is my exact setup. Maybe I don't have many issues because I literally only have the NS2/PS5Pro turn on the TV/change input. I still use the AppleTV remote to adjust volume no matter the input.
F500, we have a pretty custom ServiceNow, but all I do is put the ticket or any other identifier in the search box and go. Takes 2 seconds to be in the ticket. Granted, that interface sucks too, but I suspect your main problem is internal to your org and the people that configured your ServiceNow.
Yes. With Windows 3.x there wasn’t a lot to go wrong that couldn’t be fixed in a single ini file. Windows 95 through ME was a complete shitshow where many many things could go wrong and the fastest path to fixing it was a fresh install.
Windows XP largely made that irrelevant, and Windows 7 made it almost completely irrelevant.
