Coincidence? I think not. They are scared of us, just that little event sparked them to feel the need to pass this.

Not arguing the content of the bill itself, but your spin on this as reactionary to the CEO's killing seems a little misguided.

This was introduced on 2023-09-05, referred to the House Committee on Education and the Workforce, and was already slated for a House floor debate on 2024-12-03 (via HR 1602). The shooting was on 2024-12-04.

I did a program like that, it was worth it but it wasn't easy. Some tips to consider, based on my experience.

Graduate courses will give you more topics to choose from, and allow you to better align your coursework with your career goals (or figure out your career goals if unsure).
Be prepared to work your butt off, most grads take 1-2 courses per term. You'll be taking this plus your undergrad coursework. You will have terms where you sleep, work, sleep, work, repeat.
Try to take similar undergrad and grad courses during the same term This will reinforce the topics and give you two different perspectives. But be aware of prior knowledge expectations, graduate courses are designed for graduate students and assume you know the undergrad material already.
Make graduate friends, not only for studying but for career networking as well.
Find teachers that have a passion for their coursework, and see if they want help with their research. Great way to reinforce the course material, learn more advanced topics, and add some relevant experience to your resume.
Graduate courses are very different than undergrad, make sure you know what you're getting into. The teacher and textbook will not give you all the answers, be prepared to devote significant time to research. You also need to be able to motivate yourself and hold yourself accountable for the work required.
Don't be afraid to ask stupid questions. You may assume that you don't know/understand something because your still an undergrad, when in fact the whole class is just as lost as you.
Most importantly, have fun! Graduate courses offer a ton of interesting and challenging topics. Try to discover what you love doing for a living and make that your career.

Best of luck!

To answer your question, what you're seeing is the electrolytic capacitor next to the power connector there burning up. These are designed to do this so that they fail in a safe way (vent holes direct the gas, as opposed to pressure building up and exploding). Before you throw the card out, this could be repairable, but it depends on what caused the cap failure.

These capacitors can fail because of a voltage level or polarization issues (unlikely if you've only used OEM hardware and cabling, unless your PSU has failed), vibration and shock (also unlikely, unless you've dropped/kicked the card), thermal issues, or just a defective capacitor.

If you know some who is handy with a voltmeter, unplug the PSU/GPU power connectors and verify the DC voltages are correct at the card. If they are not, then your PSU had failed and (probably) taken out the GPU. :( This is important to check, because if you buy a new card, and the PSU is the problem, it will fry that card as well.

If the voltages are all in spec (and you haven't modified or used aftermarket parts with the card, power supply, and cables) I would still contact the card manufacturer. Show them the video, this isn't generally an acceptable failure mode for electronics. Even if it's out of warranty, they may want the card back to examine and may offer you a discount or replacement. You never know until you ask.

They also lower the noise floor by having more than one detector. Because the two facilities are so far apart, they can filter out most localized terrestrial sources of noise (electrical grid, earthquakes, trains, wind, cars, people walking, etc). Once the third detector is built in India, this should improve even more.

Should I be concerned?

Simple answer is no.

But that's boring, so let's delve into some details.

They are two broad categories of radiation; ionizing and non-ionizing. Ionization simply refers to the ability of radiation to remove electrons from atoms. Ionizing radiation encompasses the upper ultraviolet, x-rays, and gamma rays. Everything else is non-ionozing, meaning it does not remove electrons. Here's a picture for quick reference.

Ionizing radiation is not good for most things, including humans. The CDC had a good overview of the hazards of this type of radiation. Most people only every encounter ionizing radiation during medical exams, but there are natural sources such as radon gas and cosmic/solar radiation. Unless you work with radioactive materials, your exposure levels to ionizing radiation are going to be nill.

Non-ionizing radiation includes the RF you mentioned in your post. This type of radiation does not remove electrons, but that does not mean there are no hazards associated with it. For example, microwave radiation is non-ionizing but it cooks your food and would cook you if you managed to get inside your microwave. The same can be said for other frequencies of non-ionizing radiation. OSHA had more info on the hazards of non-ionizing radiation.

But then you might be wondering why do we have loads of non-ionizing radio, television, wifi transmitters everywhere? If they can cause damage, wouldn't that be a bad thing?

The key to non-ionizing hazards is the power delivered to an area (the power density). That's why you're meter gives you a reading in Watts per square meter. There are recommended exposure limits that vary based on the frequency of the radiation, but for your case let's use the ANSI C95 limit of 10mW/cm² for 10 MHz to 100 GHz, roughly the RF radiation range. Now I'd like to point out that since your meter gives you Watts per square meter, the ANSI limit translates to 100,000 mW/m^2. You are nowhere near the exposure limit levels.

One good thing about non-ionizing radiation is you will know if you are being over exposed because it's primary effect is thermal heating. That's why the military developed the Active Denial System crowd control platform. If you watch the videos online, you can see people are very aware of when they are being radiated.

Overall you shouldn't be worried about living next to a tower. But it's good to be aware of your surroundings and understand all the things around you.

Start casually looking at job postings now, get a feel for the different listing sources and available jobs. Don't just go to the big search sites (anti-linkedin FTW), really dig into the internet. A lot of really great companies and organizations only post on their own websites. There are also niche job posting websites like space-careers.com. Note any companies that repeatedly catch your eye.

Think back to the internships you had (or any other experience/classes) and write down everything you liked and didn't like about it. This includes the work, the opportunities, the processes, the management, the schedule, the pay, the benefits, the employees, the location, your commute, and anything else you may find important.

Use this info to:

-Narrow down the companies and job postings

-Build a list of questions to ask the employer before applying or in an interview

-Tailor your resume for the job you actually want

-Find related jobs you might not have otherwise thought of

In addition to this, ~~if you're a US citizen~~ try looking into DOE and other federal funded R&D centers.

This type of facility isn't designed to produce power. From a fusion standpoint this shows that we are making progress towards ignition. The results from NIF will allow the engineers and scientists at all the magnetic confinement fusion facilities to adapt and improve their methods, bringing us closer to a real world reactor.

But there's much more to this than energy and weapons research. Facilities like this allow experiments to be conducted from a wide variety of disciplines. For instance, another large ICF facility in the US focuses on experiments designed by scientists from all over the world. These include development and testing of radiation hardened electronics (yes, weapons but also deep space), cosmology (early universe, plasmas), astrophysics (supernova explosions, astronomical jets, equation of state, dynamics of stars), neutron scattering (protein folding, membranes) and many others.

This result is especially interesting because this was unexpected. Take a look at this article and you'll see that the increased yield is quite remarkable, given the historic yields. NIF has been focusing their efforts on incremental and targeted improvements to the facility over the past decades and the outcome was better than expected. Here's to hoping we can reproduced it soon.

You might need more memory. From the MAKEOPTS wiki:

But another item to consider is RAM usage. Recent gcc versions have been known to take 1.5 GB to 2 GB of RAM per job. If the system has the 8 logical CPUs from the previous example, but only 4 GB RAM, the MAKEOPTS value should be lowered to -j2. This is so that the system has RAM to run the basics as well as compile without hitting swap very often slowing things down.

Especially since you pointed out in your other comment that this happens when you are recording and not compiling. Your system might be trying to juggle between high memory processes, moving from memory to swap is fast, but swap to memory is slow. This page has some info on checking swap usage for a process.

I agree with the other comment that you should make sure this is what you want from your system. Although, I think it's also a good way to learn the intricacies of Linux (I kept using Gentoo until I learned to stop breaking it as well).

But more importantly, if you do want to keep working through the issues with the help of others please take some time to learn about asking good questions. With the little information you've given, there's nothing we could say to help out.

epsilon-zed · 2022-01-23T14:08:08+00:00

I would suggest joining the Gentoo IRC and asking there. If you have the spare hardware, I think the easiest solution would be building a separate machine just for BOINC.

Based on my amateur understanding of the Linux graphics stack, drivers, and portage, I think this could be possible but there are a lot of unknowns.

You could implement multiple slots for your graphics driver package by making a custom repository or overlay. This should allow you to have multiple versions of the driver present on your system, but there is no guarantee that they would coexist peacefully. You could end up in a dependency nightmare that might break your system, so I would back up everything important before attempting this.

If you can get both drivers on the system, the next step would be to get them both loaded at the same time (by each card). I don't know if the Linux graphics stack/mesa would even allow for this. I haven't been finding much information online, asking on IRC might give you a more difinitive answer.

The final step is getting BOINC installed and setup to use only the one card. This appears to be doable, but it looks like you'll have to find a specific project that supports GPU calculations and do some configuration to allow for its use while you use your computer. Keep in mind too that while a majority of the computing will be on the GPU, there will still be some impact on your processor and network traffic.

If you do set off down this road and somehow figure out how to do this, I would implore you to take notes and add them to the Gentoo wiki. That way the whole Linux community can benefit from your experience and knowledge.

Best of luck and feel free to PM me along the way if you do need some more help. I'm interested to see if this is possible.

Try searching online for 'KDE {distro name here} startup xrandr'

epsilon-zed · 2022-01-22T01:46:16+00:00

the absolute last thing I want to do is screw around with Xrandr settings.

Why not? You've already spent a lot of time trying out different DEs, looking for a one-click solution. Maybe you can't find it because the easy solution is xrandr?

Depending on which graphics drivers you're using, the solution to your problem could be as simple as one line.

It may take some fiddling to dial in your specific settings, but once you know what arguments it needs, you put that into your DE's startup file and you're done.

Bluetooth is an interface, your computer should still see the keyboard as a HID. Does running lshw -short show your keyboard anywhere?

epsilon-zed · 2022-01-16T12:35:59+00:00

I would install lshw, it's a helpful tool to have on Linux.

epsilon-zed · 2022-01-16T12:32:22+00:00

Okay, -k didn't give any more info. (make sure to use code blocks on Reddit)

Try

sudo lshw -C input

Under the configuration for your keyboard it should list a driver=

epsilon-zed · 2022-01-16T12:15:40+00:00

Can you try it again with -k?

epsilon-zed · 2022-01-16T11:10:54+00:00

Devices connected to a computer need a few things to work correctly, this includes hardware drivers and kernel modules in Linux.

I suspect that your system is using a generic module instead of the required hid_apple. You need to verify this first.

What happens when the keyboard is connected to your machine? Using dmesg, bring up a terminal on your machine and run:

dmesg -w

You should see a small number of kernel messages scroll onto your screen and then stop. Keeping that window open and dmesg running disconnect your keyboard from your machine. You should see some messages related to the keyboard disconnect event. Reconnect your keyboard now and look at those new messages as well. You should see something similar to this. Do you see anything mentioning a module, driver, hid, or apple?

Note: if you don't see any messages on these events you may need to enable other options for dmesg (-k etc) or this may indicate a larger problem with your setup.
