> It, in fact, does help. Voting mechanisms can help protect, detect, and/or recover from radiation-induced bit flips and outages. Early radiation-induced failures in systems can also be addressed in this way.

You are describing mechanisms to overcome energetic particles causing single event efects (SEEs). There are two distinct classes of radiation to be concerned about in space: SEE and TID (total ionizing dose). Redundancy does not help with TID.

I have done a TID test with commercial parts to prove out a CubeSat design. The parts were exposed to gamma rays emitted by a Cesium-137 source. There was not a single reset or unexplained event over the entire course of TID testing. Around 15-20 krad, the flash memory failed, which is a typical first TID effect. Charge pumps in flash ICs are especially sensitive to cumulative radiation effects.

https://en.wikipedia.org/wiki/Radiation_hardening

"Total ionizing dose effects: The cumulative damage of the semiconductor lattice (lattice displacement damage) caused by ionizing radiation over the exposition time. It is measured in rads and causes slow gradual degradation of the device's performance. A total dose greater than 5000 rads delivered to silicon-based devices in seconds to minutes will cause long-term degradation. In CMOS devices, the radiation creates electron–hole pairs in the gate insulation layers, which cause photocurrents during their recombination, and the holes trapped in the lattice defects in the insulator create a persistent gate biasing and influence the transistors' threshold voltage, making the N-type MOSFET transistors easier and the P-type ones more difficult to switch on. The accumulated charge can be high enough to keep the transistors permanently open (or closed), leading to device failure. Some self-healing takes place over time, but this effect is not too significant. This effect is the same as hot carrier degradation in high-integration high-speed electronics. Crystal oscillators are somewhat sensitive to radiation doses, which alter their frequency. The sensitivity can be greatly reduced by using swept quartz. Natural quartz crystals are especially sensitive. Radiation performance curves for TID testing may be generated for all resultant effects testing procedures. These curves show performance trends throughout the TID test process and are included in the radiation test report."
Whenever I read or that, I assume it was a language issue. As a native English speaker "codes" sounds like a mistake.
Well, I guess once the system is rewritten, we will not get our refunds until 3 years later.

I wonder if I get 2x by expected refund the IRS can come at me to claim the extra amount :)
Yeah, the software process was developed from the Japanese manufacturing processes (which use kanban cards as singals in their inventory systems).

The basic concept is the same - minimize wasteful work in progress. In manufacturing, this is excess inventory at any point in the production pipeline. In software, this is excess tasks in a state of partial completion.
I don't want to delete my account either, because I use fb to stay in contact with friends spread around the globe. (Granted: Very rarely to post something in local groups also.)

But my bookmark points to facebook.com/messages and I practically never look on my feed. I guess (/hope) I'm about as valuable as a deleted account to facebook. Please feel free to correct me if you have some insights into this!
That one's a bit more complicated. Our interests intersect with theirs along many axes. And they have lots of lobbyists in DC and Americans of Israeli/Jewish heritage donate lots to DC politicians along Israeli policy lines. People of Russian heritage on the other hand typically have opposing views to that of Moscow in many areas, so they are not as aligned, if at all; in addition, many people of Russians descent have Jewish heritage as well... So you know, they doubly oppose Moscow.
I can only speak for Germany. Here, we have a big exception to the normal rule that you own the rights and cannot reassign them: everything you create during work hours under a normal employment contract is automatically the property of your employer. Even if you create stuff outisde work that may be useful for the employer, the company has access and may get the rights (for a fair compensation according to the law).

Also, even though you cannot reassign ownership, you can grant exclusive rights. This is the closest analog to assignment of copyright.
Challenge: they have WiFi on the ISS. Pick up the signal from earth and tell me what SSIDs they use.
It not only creates a bias (which decreases entropy), but its an operation that would easily be implemented faster on an FPGA than on a CPU. I mean, its basically a singular LUT, there's nothing more efficiently done on an FPGA than LUTs.

Basically, I think it actually weakens the FPGA-resistance of Cryptonight.

Fortunately, the main idea of the changes would discourage ASICs being made for Monero. But it doesn't seem to discourage FPGAs, which are just one "resynthesize" away from fixing any code changes. And as long as the community becomes accustomed to regular changes, then any issues in the encryption can be fixed later.

I can understand why someone does not like GPL, but calling a license which says you have to pass on the same rights you were given a 'fascist' license makes absolutely zero sense.

60 Minutes did a segment on Huawei a couple of years ago where they discussed the extreme concerns intelligence officials had with Telcos using Huawei equipment. At the time it just seemed like a very strange segment, this was of course before the Snowden revelations. I have thought about that segment many times since the Snowden revelations and it starts to make sense why intelligence officials where so concerned.
> I think the same is true with Bitcoin: traditional banking that takes days and charges high fees can be easily implemented on Bitcoin, but the opposite is not true.

"Easily" here seems like major exaggeration. If that were true, projects like Lightning wouldn't exist.
I think their problem is that they need to keep old deploys alive for a long time because they have stateful long-running connections. So a blue/green deploy wouldn't work because their blue deploy has to stay around for at least a month after green is deployed. There's no difference between the SHA and COLOR, I think the choice to use a git hash is because it's the logical choice (instead of randomly choosing a color from a list).
Many of us have family spread all over the country. I can keep in contact with them all via a facebook group instead of one at a time over the phone or group text (...not that my mother would understand how to do that) or the like. Even if you don't appreciate how it connects you to your friends (if it even does), surely you can appreciate how it can connect you to your family.

Thanks. It's really interesting. It seems that I posted a stupid comment. Sorry for that.
It's not as simple as using auto-prefixer, since IE10 and IE11 use the older syntax. However, it's surprisingly not that bad for simple layouts.

Here's a great resource covering the hows and whys: https://rachelandrew.co.uk/archives/2016/11/26/should-i-try-...

And here's a simplified example I threw together recently to demonstrate it in action: https://codepen.io/shahab/pen/ypWmZG

Basically, you lose auto-placement, named grid areas, and simple grid gaps, so you have to manually place items in the specific row/column for IE. But, I've found that it's still easier than the alternative in many cases.
Certainly. As you said,a hostile nation state targeting a nobody (like myself) would gain no new information by the fact that it knows I used Tor to access nytimes. Unfortunately, intelligence community and law enforcement agencies do not presume innocence. They would presume that you're a "bad guy" who is "trying to hide". What harmless sites you visit is of little importance to them. You're a likely threat,essentially, a Tor user is an active target for proactive LE and Intelligence gathering operations.

This isn't parnoia,the snowden leaks which dated around 2008 show the NSA targeting visitors of sites like linux.com (xkeyscore).

When hunting for "threat" you look for the people trying to hide. For example,they love it when people use PGP encrypted emails,their sensors pick up on that and they correlate metadata gathered from that communication for further intel gathering and offensive targeting (PGP does not encrypt email metadata)

So,using Tor with a nation state actor or LE agency incorporated into your threat model would be very bad in my opinion,even if all you do is visit nytimes over https via hidden service with noscript.
> And we continue to tolerate those who wouldn't tolerate us...

It's interesting that as an American, I can't tell if you are talking about the Chinese or the "liberal elite Americans" when you state this. That's a common talking point of the American right wing and could equally describe the position of any person who uses that Chinese term in seriousness.

Also, the hypocrisy of a Chinese word criticizing westerners for enforcing political correctness is humorous.
Wow, thanks for sharing. That site and all the sites it links to restore my faith in humanity.
This argument would hold more weight if the government was saying not to use any non-US phone. But they're specifically targeting Huawei and ZTE. Notice that there's no recommendation to avoid e.g. Samsung phones.
> OK, so now if Bitmain develops an ASIC they just won't tell anyone about it.

"Moving forward, developers will seek to protect the network’s ASIC resistance by slightly modifying its PoW algorithm at every scheduled hard fork, which generally occurs twice annually. These changes will not be noticeable to ordinary XMR users, but they will alter the network’s hashing algorithm enough that Cryptonight ASIC miners would become obsolete following every fork."
Most of the UofU Chinese teachers are Taiwanese, and they aren’t funded though the Confucius institute (rather, there is a deep connection between the LDS church and Taiwan, which allows missionaries). I had one chinese teacher at Utah who was really against the Mainland government (and mainlanders in general), I don’t think his contract was renewed but he was a really funny guy and a decent teacher (had a blonde wife, seven boys, only in Utah).
Banks are very different from cryptocurrency. The economic value of banks is through loans, not monetary transfer. Through loans, and regulations/backing of a central bank, money is created. This economic effect is what enables economic growth. The money created by banks likely offsets the energy/overhead. https://en.wikipedia.org/wiki/Fractional-reserve_banking
Back in the Bitcoin days FPGA mining had little or no advantage over GPUs.
Thanks for the info. I don't recall if Stretch requires module rebuilds on kernel updates but that hasn't bothered me in the past. And I always reboot before removing old kernels just to make sure that I don't really need them.

I'm using ZFS on extra storage - not on /, /boot or /home. On one box I do have a ZFS volume mounted to my ~/Documents directory. I did try to install ZFS on the boot device and after thrashing a bit I decided to wait until the installer supports it. I have a file server and remote file server for backups and I'm preparing upgrades for both that put the served filesystem on ZFS and sends incremental snapshots to the remote to keep it synced. The existing system uses `rsync` to synchronize.
I am really looking forward to "The Future of Organizations". I think decentralized governance and consensus is one of the most exciting aspects of these technologies, but are being totally drowned out by the fintech applications in the meantime. Hopefully this article will address some of these possibilities.
I've thought that I needed some such when I last taught trigonometry. Sure, it's a graphical introduction to the applied math of Fourier series.

The OP started saying that the horizontal axis was time but later discussed 180 degrees without connecting degrees with time.

Why the harmonic frequencies are distinct positive whole number multiples of the fundamental frequency? Because the sine waves at those frequencies form an orthogonal coordinate system with all the advantages of such a system in 2 and 3 dimensions we know well. Similarly for linear algebra with positive whole number dimensions. So, right, the periodic waves are in a vector space of countably infinite dimensions. Usually in practice we can get good approximations by considering only the first dozen or two harmonics.

The waves travel according to the wave equation. It would be good to connect with that.

The lecture might have discussed the effect of tone controls and linear systems and linear filtering more generally.
For those that go this route, I found that getting to about 40% mastery for any given test bank is good enough to pass with a safe margin. That is, being able to answer 40% of the questions right every time the same one is presented.
Basically you'll find that the Tech is really just "do you know the regulations", the general is "do you know the bands" + basic radio architecture and the extra is "do you know antennas" + some niche/DSP stuff
Usually newer POW algos are very memory heavy to make FPGA mining impractical.
http://coinhive.com/ also offers this but users do not seem to like it. They offer two miners, one which only operates with users consent and another one without explicit consent. Either one seem to have been banned by my ad blocker, although the one which requires consent has a not which clearly states that it should not be in any filter because they user wanted to run the script and it might break the website.

They even have a pretty cool usecase for it too: to have x amount of hashes as a captcha replacement, with a nice UI and such (you can find it by click on login at their page & disabling your ad blocker). Unfortunately, it does not work really well for many of my use cases. When I'm on my phone it is fairly slow. When I'm on an old phone (iPhone 5 and 5s, for instance), it is so slow that many users would just close the page because they believe it is broken but it probably is a decent defense against brute force attacks because it still requires quite a bit of work to try a login.

Let's see, if the US is listening in, then there's a small chance they will misinterpret my actions as suspicious, arrest me, and perhaps even lead to my imprisonment. This may include extraordinary rendition, should they make that decision while I am in another country.

If China is listening in, then there's a chance I will be denied a visa to visit China or, should I be given a visa and visit, then they can arrest me, etc.

Upsides in either case? None.

So I would rather have China listening in than the US.
Failing to see the relevance of tax returns not being filled.

I'll ask my original question.

Have these "operatives" done anything that is not particularly unusual compared to other student groups? Until they have, this fits the very description of fear mongering.

You don't magically have access to anything just by entering the US.
it probley wound be better if the usa split the FBI in two

1 A federal police force (with reduced surveillance powers) which would take over the BATF and the currency and uniformed part of the secret service.

2 A separate contra espionage organisation similar to MI5
Toyota use more outsourcing producing a lower % of their cars than Tesla.

So, comparing things on a man hour basis might be more meaningful. Toyota is 12x as large though they both do more than just manufacture cars. Still it's probably about the equivalent of 3-4 months worth of Toyota's production capacity.

PS: Yea, modern batteries are a horrible pain to manufacture.
That's really funny, because a couple of years ago, Snowden demonstrated very clearly that American tech companies are all infested by NSA mass surveillance tools or dominated by mass surveillance activities, constantly profiling pretty much all citizens.
Indeed, I'm frustrated in any of these situations where ambiguity seems purposeful. Is it "The Chinese" government? citizens? race? The article begins with Chinese government-sponsored operatives, which is OK, because at least it is a specific accusation that can be discussed. But then it immediately generalizes to list the number of Chinese nationals enrolled, perhaps to allude to the potential scale. (Your classmate or colleague could be a Chinese spy!) That to me seems a few steps away from "Well, I've read these reports about how the Chinese want to steal everything, so I'm going to pass on hiring this guy with the funny Asian name." or more extremely, "Well, we know that not that everyone is a bad guy, but for security, let's round them up into camps, just in case."

I wonder it they will be able to fix this OTA, or will require a trip to the dealer. How can you perform a firmware update on a system rebooting every 45 seconds?
No one seems to know about RLDRAM3 yet in the cryptocoin community. Prior to my post a few days ago, I couldn't find any information on the subject (which is why I wrote something up on Reddit).

I'm trying to bring up the issue actually, because I think its the obvious elephant in the room. In effect: ASICs are ALREADY made to solve the memory problem, they're called high-speed low-latency RAM (IE: RLDRAM3, QDR-IV, or HMC).

But it seems like most people in the cryptocoin community is only familiar with DDR3, DDR4, or GDDR5 RAM. I think the "exotic" low-latency stuff is still not really well known yet.
This wouldn't qualify under the California Lemon Law - it may very well take a dealer more than three days to diagnose the issue, for example, in this case, the diagnosis is occurring at the manufacturer, and a fix being worked out.

It would be another thing entirely, if the issue kept occurring, repeatedly over months, and the manufacturer was unwilling or unable to repair it.
Actually FPGAs had 10× better energy efficiency. This was huge. Eg. the popular Spartan6 LX150 used in many miners was rated 50 joule per gigahash, compared to 500 J/GH for an HD 5970. I used to run both GPU and FPGA mining operations. That said, they were comparable to GPUs in terms of $/GH.
> If the government is worried about trojans, malware, etc., then they can easily hire an auditor to audit the code and vouch for its authenticity.

Not that I disagree with the general idea of democratizing this sort of big government contract, but, well, this is a much bigger hurdle than you are making it sound like. Audits can be good at finding unintentional flaws, but a skilled adversary can often create code that looks safe, but in fact, isn't. Consider the underhanded C contest: http://www.underhanded-c.org/

On a personal note: I once worked on a large research project for detecting malicious behavior on Android apps, where the idea was to produce tooling to find underhanded/undocumented behavior automatically. The project had a red team. By the final rounds, we were getting code from them where the malicious functionality was extremely hard to find via either tooling or manual inspection. Keep in mind these were simple programs, rarely over 10k lines of code, written in Java which is a remarkably transparent language to read, and that we were allowed to ban features like reflection or raise the alarm on anything that looked like intentionally obfuscated code. Additionally, we knew each of those programs had malware in them. Reporting 'clean' was often just saying 'you win, we give up, couldn't find it after staring at this 2k lines file for a week'.

In theory, when working with a large contractor, you can put controls on how the software is built, not just the final code, and you can hold them accountable for backdoors discovered long after the fact. Now, not saying this always works that way, but it might still be better than accepting a system built by someone you only know from their Github handle and who might or might not live within your jurisdiction. The state of the art in software verification would need to change a great deal before that is a good idea.
> So, your medical plan evaporates the moment you stop working for most federal agencies? Just like my private employer's medical plan?

Yes.

>And guaranteed pensions are no longer a thing?

They pitch it as a three legged stool: social security, your 401k, and then a pension that pays out according to a formula (the amount you get in a year is calculated somewhat like pension := (1% of the average salary of the three highest paid contiguous years of service) * number of years of service, up to 20 (after 20 years the percentage goes down). Between the three legs of the stool you can probably get to about 60% of your income, which is supposed to be reasonable for retirement.

> What is left as a justification for below-market salaries? Employment opportunities in government-dominated towns (which do not have healthy private-sector economies), and more job security?

The salary isn't at all bad. For some specialties it's below market, but for the average joe it's pretty decent. But it's worth noting that, for me, the job security is key. I've made more money contracting, but contracts end, sometimes abruptly, and the peace of mind you get from having security is very valuable.
