YakBizzarro··on AMD announces the Spartan UltraScale+ FPGA family
Interesting product. It seems they ported some feature from the Versal family, like the hard LPDDR controller and the new XP5IO, so not just a cut down version of the bigger Artix
YakBizzarro··on HP printer app is installing on PCs whether they have HP printers or not
The M148dw is a semiprofessional printer,so it doesn't have all the typical hp crap. You can even allow 3rd party toner and disallow firmware upgrades
YakBizzarro··on Italy bans cultivated meat products
Yes, but Italy is a parliamentary republic, the president has only a ceremonial/ guarantee role. Governments/parliaments last much less, maximum 5 years, but often way less
YakBizzarro··on Why IBX and Why Lazarus (2011)
Much clearer, thanks :)
YakBizzarro··on Why IBX and Why Lazarus (2011)
And so? It seems to me a very legit wish, they have tons of code to rewrite for little benefit. And this is the extreme opposite of just complaining: they took their critical missing component, ported to the new ide and released for everyone
YakBizzarro··on I wouldn't be productive enough for today's academic system (2013)
That's the sad reality of most grants today
YakBizzarro··on WiFi can read through walls
The only result will be that the router of my neighbor, provided by his ISP, will happily reports the inside of my apartment. Sorry, I can be excited for a radar-based controller for a console, but as part of wifi, I can't really find any legit use
YakBizzarro··on Plans to cut speed limits ‘will significantly improve road safety' – minister
Swiss don't break rules because there are speed cameras everywhere and fines are huge. But as soon they are outside of Switzerland, they will be the first to drove like hell is coming. Also, if you don't react to green light in a microsecond, or drive less than 10 km/h under the limit, they will start to honk. Rules and their enforcement are perfectly fine and I'm really happy about that, but it doesn't make drivers better
YakBizzarro··on Quench of LHC inner triplet magnet causes a small leak with major consequences
Oh yes, way too familiar situation... dry cryostats were really a game changer. Apart of the incredible advantage of not having to refill them frequently and on Sunday, they are much more reliable and without any cold seal
YakBizzarro··on Unauthenticated RCE on a RIGOL oscilloscope
Trust me, it's not the case. I sell electronic instruments for laboratories, and in the large majority of the cases they are simply attacched to the local network. And such network has simply internet access. I once made a blogpost to advise our customers how to create a local instruments network for higher performances and security, but I don't know how much impact it had
YakBizzarro··on Frozen heads and bodies await revival at this Arizona cryonics facility
Sounds like an episode from Futurama...
YakBizzarro··on Westinghouse AP300 Small Module Reactor
well, not really. the fuel in typical reactor is lowly enriched uranium (LEU), meaning that only a small percentage of the fuel is actually fissile (ie. it breaks when interacting with one neutron and release energy). So no, it can't get sustain an exponentially growing reaction chain in any condition, since neutrons are absorbed by the non-fissile part of the fuel
YakBizzarro··on The weird world of Windows file paths
If I rembember correctly, you could use the B drive even if you have just one unit. It was useful to copy files from one disk to another, even if you didn't had an hard drive as temporary storage
YakBizzarro··on OpenWRT 22.03.4
GL.inet are not using openwrt from factory. You can see in many forum threads. It's a custom one, sometimes derived from vendor SDK, like qsdk. I have one very nice small router from them, which can run mainline openwrt, but this is not always the case
YakBizzarro··on Nyquist Frequency
That's true, but there are a couple of things more. First, your DAC or ADC need to have such analog bandwidth. Working in a higher Nyquist zone also require higher amplification since the signal would be considerably weaker and more complex filtering to remove the signal from the other zones
YakBizzarro··on Viable superconducting material created in Rochester lab
A lot would depend on the critical current and critical field that such hypothetical superconductor could have. If it's too low, its usage where large currents are needed, like motors or chips will be small. As example, look into the generation of high magnetic field. In a typical physics lab or MRI machine, the current state of the art is by superconducting coils, but for very large magnetic fields (several tens of teslas) you need to fallback on copper, since there are not known practical superconductor able to sustain such fields without losing their superconductivity
YakBizzarro··on AMD Alveo V70 AI inference accelerator card
I suspect that it still has some fpga fabric attacched to the ai engines. The two parts are separate, but according to Xilinx docs (talking about Versal Soc), they are supposed to work togheter
YakBizzarro··on AMD Alveo V70 AI inference accelerator card
Interesting. It seems then that the xdna architecture in the Ryzen 4070 is nothing more than a port of the existing Xilinx Versal cores (fpga+ai engine)
YakBizzarro··on Motorola 68030 wire wrap prototype
The modern equivalent is simulation on a series of big FPGA, probably this one https://www.xilinx.com/products/silicon-devices/fpga/virtex-...
YakBizzarro··on Intel Officially Introduces Pay-as-You-Go Chip Licensing
In my experience, it's the exact opposite. The gain of such things in logistics, stock management, production are much better than a slightly higher cost of goods. It enable to sell stuff even in cases when it would be too expensive, and enable cheap followup businnes. I would say that such model is much more acceptable in b2b
YakBizzarro··on Qatar World Cup critics are unprepared for the rest of this century
Same in Tunisia(about burqua and minors) a very muslim country. France is quite integralist in their laicism, but let's not exagerate
YakBizzarro··on UK food price inflation hit 16.2% in October – cost of food basics surging
You are mixing two things: Yes, illegal immigrants get into Italy from the Mediterranean sea. From there they move to north Europe, but this is far from getting Italian citizen and have the freedom to move in EU. However is sometimes very easy for many south americans to get Italian citizenship thanks to our dumb citizen law that grant citizenship to anyone who could prove to have kind of remote Italian ancestor
YakBizzarro··on The surprising afterlife of unwanted atom bombs
Here a nice thing of nuclear warhead maintenance/decommisioning of nuclear warhead. The article discuss mostly about the plutonium cores, but modern weapons uses triutium to boost the yield, see https://en.m.wikipedia.org/wiki/Boosted_fission_weapon. Tritium is faintly radioactive, and it decays over time in the stable helium-3. This is a quite rare isotope of helium, in comparison to the much abundant He4. He3 is much needed in dilition refrigerators, the big machines often seen in advestisment of quantum computer. So such activities on nuclear weapons are the source of a critical and scarce ingredient for quantum computing!
YakBizzarro··on Authors’ names have ‘astonishing’ influence on peer reviewers: study
In my experience, at least in the field of Solid-state Physics, double-blind review is quite rare. Also, it would be challenging to implement, since it's often very clear who is the group that submitted a paper. The community is not so big, everyone know everyone, samples and techniques are quite peculiar for each group and a paper typically cite a lot of previous work, to avoid large repetitions. It's not uncommon to guess well the reviewers
YakBizzarro··on Ask HN: Seriously, steelman this please. 7,400 employees at Docusign?
Clearly you have never done or received customer support in a b2b environment. It can be as valuable or even more than the product itself.
YakBizzarro··on AMD Ryzen 9 7900X / Ryzen 9 7950X Benchmarks Show Impressive Linux Performance
any reference to that? I would like to read more
YakBizzarro··on Ghana bans a Delta Boeing 767 (yes, just one)
I think Airbus is trying to position the A321-XLR as replacment of the 757
YakBizzarro··on Perfluorocubane is (as you would expect) weird
Not far from reality, indeed. Every time you have some molecule with a free electron, you can perform Electron Spin Resonance on it. You take a small amount of the molecule, put in a strong magnectic field, and with microwave you could drive the transition between the down and up state (parallel and antiparallel to the magnetic field). However, with a conventional spectrometer you can't control a single spin, because its signal would be tremendosly low, you would need at least ~10^13 molecules (maybe even less nowadays). If you want to use a single molecule, you need to connect to some kind of nanofabricated structure, in order to control and read it out. It's feasible, many works showed that, but very very difficult to engineer. You could spend most of your phd trying that (a pretty common tale in the field).
YakBizzarro··on Application submitted for US molten salt research reactor
A moderator is not used to control the reaction, but to make it possible. The neutrons produced by fission, have high kinetic energy, and fuel has a small cross section for neutrons at such high energy. A neutron moderator slows down the neutrons, making them more likely to interact with the uranium and split them. typically water is a good moderator, but here they use graphite for obvious reason (high temperature salts doesn't play well with water)
YakBizzarro··on Application submitted for US molten salt research reactor
Not compltly accurate. It's true that the half-life of tritium is short compared to long lived actinides. However, like hydrogen, it diffuses very easily and it's not easy to contain. In fact, it's one of the few things emitted in the environment during normal reactor operations. As beta emitter, you are right that it's dangerous only when ingested, but it's very easy to breath of to get it from other ambient sources
