Where are your weight figures coming from, they are not in the linked article.

Packaged semiconductors are going to be more metal interconnect / plastic encapsulation / ceramic insulation than silicon by weight.

These systems will also have a significant weight fraction in magnetic materials, either ferrite ceramics or amorphous metals.

Still a huge weight savings, but the weight fractions you are giving see off and are missing some important materials.

I was a volunteer for the rescue program in 2018. I am not sure what the exact criteria were, but dogs from the Chernobyl exclusion zone have been re-homed before.

A few dogs which otherwise would have been good candidates were too internally contaminated to re-home. Not too bad, it would have been something equivalent to a few x-rays a year if the dog slept on your bed every night. But the modal rescue dog has no radiation risk at all to worry about.

Beyond that, the workers in the exclusion zone are quite fond and protective of the stray dogs, so I think there would have been significant blowback if a significant portion of the dogs were re-homed.

Although I was not involved in the study itself, I was a volunteer for the rescue program in Chernobyl in summer 2018 when a lot of the data was collected. I assisted with checking radiation levels / decontamination and operating a whole body radiation counter to measure the radiation levels of the dogs for a different study.

The stray dogs in the Chernobyl exclusion zone were surprisingly friendly. Better socialized and behaved than a good number of pet dogs I see in the USA.

As mentioned elsewhere in the replies, if you think the program is interesting, consider donating to the Clean Futures Fund: https://www.cleanfutures.org/dogs-of-chernobyl/

As a STEM PhD student I felt a bit jealous reading this. Then I remembered that law students pay tuition while many PhD projects are funded by companies in industry, often at a somewhat dubious value proposition. There is at least a mild expectation you would consider working for the project sponsor after graduation.

There is a lot of money being thrown around towards recruitment in many fields. Tuition is worth a whole lot of free food and branded swag.

The article states that only first party data collected by NYT is used for the model. They also use no demographic data.

It seems that the only data that leaves is your previously read articles.

Amusingly, this implies that there are articles that actually increase your free article limit when accessed.

Are there different variants of DALL-E Mini? Running prompts through both this version and the one hosted on huggingface gives noticeably different results. The one on huggingface seems to give more accurate responses.

The MIT 5th year masters program for EECS requires a thesis and for you to find a faculty thesis advisor that is separate from your academic advisor.

I took some glass blowing classes in undergrad and wanted to make something with uranium glass. I bought uranium glass frit from Gaffer glass and used it, none of the instructors or students seemed to mind. The main concern was the dust when pouring out the frit, once it is melted into something its pretty inert.

I made some cool stuff with it (only limited by my glass blowing skills).

Does this behavior anger anyone else on a deep level? I get that its hard to buy GPUs right now, but this seems like such an attack on general purpose computing.

Hardware manufactures already segment features between consumer and busness grade parts that the silicon itself is capable of, such as virtualization, but restricting what algorithms one can run is a whole new level.

I am pretty sure my next GPU is going to be AMD due to this behavior by Nvidia.

The article is wrong. If you read the report its $30 - $50 million dollars, not billion.

I was a bit perplexed as to why the total could be so large....

One of my friends got jabbed by a used needle in a pair of pants he bought from Dollar a Pound. It was not a fun experience for him...

I liked the clothes I got from there though! I found a cool jacket once.

Reading through the paper, I think the real buried lead here is that the reviewers discriminated in favor of selecting black and hispanic applicants, with a larger effect size than anything analyzed but test scores and attractive vs unattractive (not neutral vs unattractive). This includes obesity, grades / class rank, research publications, and honor society membership.

At least your appearance and test scores are mutable characteristics.

Its a material that basically gives electrons "inertia" which acts like an inductance derived from magnetic fields. There is a time constant to it, which determines at what frequency range it starts contributing to the inductance value.

To make it useful for power electronics they would have to push out this time constant by at least 4 orders of magnitude, I don't believe the theoretical material properties support that.

You might see this shaving off a few mm^2 from RF ICs and providing better RF performance. Applications in power electronics, where inductors take up the most volume, seems unlikely.

The medium article links to a nature article which explains in depth: https://www.nature.com/articles/s41928-017-0010-z

This seems like an interesting development, but the performance gain appears to be limited to low value inductors in the 10's of GHz range. Those inductors are already very small and easily integrated on RF ICs.

If you want to miniaturize electronics you need to miniaturize the inductors used in power conversion, which typically operate in the KHz to low MHz range. It's a very different problem.

The UC system has a common application and students rarely apply to only one school. The impacts of any outreach effort should be seen across the entire UC system and not just Berkeley. Based on the data for the entire UC system, you can see that is not the case https://www.ucop.edu/institutional-research-academic-plannin...

What has changed though is that UCB has a new admissions dean.

Affirmative action in California is banned by Proposition 209, which passed in 1996.

Its great they are making an effort to boost diversity, but I don't see how a single year jump this large was accomplished without implementing affirmative action.

The UC system already has an ongoing lawsuit over affirmative action in their admission practices, it's a bit scary that they are now so blatantly violating state law.

I clicked on the article thinking it would be that. I got into electronics making little BEAM robot things from salvaged parts. BEAM robotics seems pretty accessible and has an interesting design ethos.

I am currently a PhD student and have been wanting to get into IC design so this seems immensely exciting. I do power electronics, so hopefully they post info on the analog parts of the PDK soon.

An open source DC/DC converter that can be integrated into other projects seems like it would be an interesting candidate for one of the first fab runs.

What are the near term implications of this? I was under the impression that this was always considered a pretty extreme option. Between this and the plans for the TSMC fab in the USA I wonder what suddenly shifted in US - Taiwan relations.

Does this mean that Huawei loses the 5G competition because they are not going to be able to get the chips they need fabricated?

Is China going to try to split up Huawei into a bunch of "totally not Huawei" companies?

It's a shame that copyright works in such a way that it allows all these old and historic pictures to be sequestered away from the public long after all the original creators are gone.

Again, there are many articles that argue either side of this. You can pick and choose quotes however you like.

That being said, you don't believe that a lab that studies novel coronaviruses could be studying a novel coronavirus? There is a history of pathogens escaping labs and there are many more wet markets in other cities in China than labs doing related research. As the simplest approximation just try applying bayes rule.

Additionally, the CCP is an authoritarian regime with a strong motive to cover things up. A refusal to even consider the possibility of a lab escape is willful ignorance.

Fundamentally, you are not going to find any direct evidence that the virus came from a lab unless the virus has signs of being engineered (which seems to not be the case).

Only in the last week or so major news organizations have started covering the theory of lab escape of an unmodified pathogen. You can find tons or articles arguing either way.

Given the fact that almost every city in China is going to have wet markets, but Wuhan is one of the few (only?) cities to have labs researching these types of viruses it would be irresponsible to not consider the possibility. Given that the CCP is going to do the utmost to cover up any negative stories you are never going to find any smoking gun level evidence.

I really hate how the media keeps conflating the theories that the virus was engineered and that the virus escaped from a lab. Even the title of this article has been editorialized to conflate the two.

I mostly trust what people have said about the virus lacking signs of being engineered or otherwise modified.

That the virus escaped from a lab is totally plausible and has precedent. It is a shame it gets lumped in with the other theory. SARS escaped Chinese research labs twice and there are many other instances worldwide of pathogens escaping research labs.

I have been meaning to try making my own bread. Now that I am on lockdown I have even more incentive. I like that all the recipes in the repo are FOSS. Got to break free from big bread!

Why do you recommend toasting the bread? Is it something related to the yeast or just the fact that my first few attempts may be a bit unpalatable?

I followed this tutorial when I Fallout 4 first came out and I had not yet built a desktop. It worked pretty well and, given spot prices, was pretty cost competitive with a gaming desktop if you only cared about one or two games.

AWS inbound traffic is free but persistent storage is not so I downloaded the entire game whenever I spun up the AWS instance, which probably happened 10+ times. I still wonder how much that cost Steam in terms out outbound traffic....

It is a shame that almost all of the low cost PCB and PCBA services are in mainland China. I do a lot of work with hardware and given recent events I have been treating it as a moral imperative to find somewhere to have my PCBs fabricated that is outside the rule of the CCP. Everywhere else has been significantly more expensive.

I wonder what it would take to have a robust electronics prototyping industry in the west or in a less authoritarian part of asia.

Seems like its only going to be VR. Thats sad. I love halflife games but I am not going to shell out hundreds of dollars for a VR headset to just play that game.

I don't understand why the BDS movement against Israel gets so much attention when stuff like this, or worse, regularly occurs in China. I have been making an effort to reduce what I buy from China recently, which is difficult in electrical engineering. I hope others consider the same. We need a BDS (Mainland) China movement.

I have been tracking a few and commented on one. It does not seem like they are being removed.

Sadly, it just seems that no one is commenting on them. Perhaps people are burnt out on talking about related issues or this is a chilling effect of moderation on previous related issues.

It is a shame that this is not getting more attention, I see the actions of the CCP as the biggest threat to western values globally.

I interned at Meraki summer of 2017. I have never heard of a company poaching employees as viscously as Samsara is from Meraki. Based on that I would say that Meraki is on the loosing side of "cool".

I also wonder if Cisco would have changed their acquisition offer if they knew how many employees would be poached.
