Comment Uncontrolled airspace incursion (Score 2) 79

Forget about whether or not this is or isn't spying. Even if you take their claims at face value, this balloon would represent airspace incursion by an out-of-control unmanned aircraft. And airspace incursions are something the US military should handle, efficiently and promptly, as a matter of routine. This shouldn't be a giant diplomatic incident or require some great policy analysis to decide to take it down. The message should be plain and simple such as:

In the interest of the safety and security of people of the USA, we have ended the flight of your out-of-control balloon which had entered US airspace without clearance or authorization. We reserve the right to inspect the wreckage as part of our investigation of this incident. After that investigation is complete, you may make arrangements for the return of the aircraft remains, at your expense, via any US embassy. Sincerely, North American Aerospace Defense Command (NORAD)

NORAD almost certainly knew about this balloon heading towards our airspace probably 5 days ago (late Monday or early Tuesday) when it was still many hundreds of miles away from the west coast, which means that authorization to shoot it down would have been requested at virtually the same time. There should have been plenty of time (hours) to take care of this safely and efficiently before it actually entered US territory, but my guess is that the authorization to shoot it down didn't come until much too late... possibly as late as Wednesday, after it had already crossed into inhabited US territory. Hence the reluctance to shoot it down, and hence the uproar.

Comment FCC Broadband Map challenge process is flawed (Score 3, Interesting) 88

One of the best parts about the FCC Broadband Map in my opinion was the idea that it was essentially "crowd-sourced" in that users could file challenges to the data and fix mistakes. But I was surprised to discover recently that there are huge limitations on the challenge process.

A month ago, I was interested in purchasing a property and one of my criteria was having fiber service available. The FCC Broadband Map showed fiber being available there, but before placing an offer, I called the broadband provider to confirm. The representative on the phone apologized and said that no service was available at that address, nor did the system show it becoming available soon. I mentioned that the info at the FCC Broadband Map was incorrect for this address and needed to be corrected, but she did not know what to do about that, but she would "make a note about it" and pass it along. I happened to check the map again about 30 days later, but it was still listed incorrectly. I decided to be helpful and file a challenge myself directly via the FCC website.

Unfortunately, before clicking on "submit" you are required to certify that you are either a current resident at the address or are the legal owner/manager of the property. No one else is permitted to file a challenge, based on the current website language. That's a significant hindrance in this case, because the current owner of the property obviously has no incentive to update the map to make the property look worse to prospective buyers, and obviously the provider here can't be bothered to fix it either. If interested 3rd parties are not allowed to file challenges on behalf of others when they have evidence, then the entire challenge process is sadly flawed and strongly designed to favor the status quo.

In fact, based on the OP, it sounds like this challenge which came from a competing ISP was actually against the FCC's own challenge policy, and I'm pleasantly surprised it went anywhere without simply being tossed/ignored.

Comment Re: Nothing is new under the sun? (Score 2) 65

Yeah, reminds me of sparse imaging / compressive sensing too. Nothing new here except perhaps they aim for a consumer product. I would still welcome any device capable of imaging at high resolution and wide dynamic range without a lens. Lenses are so medieval, we should do better.

As their paper points out, these pinhole systems really suffer from the fact the the imaging aperture is TINY. This produces a low resolution, high depth of field image like a camera with a very "high / slow" F/# .
High degrees of multiplexing also require high bit depth measurements and low noise, driving sensor cost up.

Comment Nothing is new under the sun? (Score 4, Interesting) 65

The way the NPR article describes this, it is no different from Uniformly Redundant Arrays, i.e. Coded Aperture Imaging: see https://en.wikipedia.org/wiki/... If you look at the 1998 paper, "Uniformly Redundant Arrays" by Busboom et al, the first sentence describes work from the 1960s:

Coded aperture imaging (CAI) (Mertz and Young, 1961; Dicke, 1968) has matured as a standard imaging technique in X–ray and Gamma-ray astronomy. It is capable of combining high angular resolution with good photon collection efficiency by using a mask consisting of transparent and opaque elements placed in front of a position sensitive detector (Figure 1).

So is the only innovation here using more pinholes, more pixels, and more processing than were around in the 1990s?

Comment War was not invented 10k years ago (Score 4, Interesting) 151

The title is pretty honest: this is early evidence of war. I agree that we likely cannot observe too many battlegrounds 10,000 years later. The annoying thing about these reporting on this article is that it makes it sound like humans invented war 10,000 years ago! A human 10,000 years ago is virtually identical to us today, so why would we expect them any less capable or motivated to commit mass murder than someone today?

Comment Re:Go for servers (Score 1) 197

Having done this twice in the past 4 years, my suggestion is to use rack mounted x86 PCs/servers with dual graphics cards. With ATI cards you can go to 8 or 16 monitors per server and as long as you keep a ratio of 1 screen / cpu, you should be fine (capacity wise). Using PCs (a) will allow for easy maintenance and (b) will be easy for others to work on them. PCs are also much easier to upgrade (hardware wise) as they keep the manual effort needed to a minimum. We've done this with PCs and PIs. PIs are a fun project and so far they work well, but you *will* be swearing in the process as you will have to figure out many things, including power, cabling, mounting, etc.

I built a setup like this (50X LCDs) closer to 10 yrs ago with a rack of servers, and I think it was a mistake. I should have used small desktop PCs. I was somewhat budget limited, so it was a bit of a stretch to get all the monitors driven by the limited set of servers + multiple video cards. In the end I had an array of client machines network-booting from a single server. I could have used a rack of small desktops as the clients and had 2x more CPUs and higher performance graphics cards for the same price. I would have kept an extra ~10% desktop computers on hand to swap in if any failed. Since they were network booting, there was minimal setup to add a new client to the system.

Do you own an IPhone? Why is that product made in China rather than the US? Oh right! The wages for factory workers in the US were to high so they off-shored all the manufacturing jobs to a cheaper labor force.

Well welcome to the same treatment.

It's not the "same treatment" at all. In the one case (outsourcing), unskilled jobs are moving overseas not due to government interference but due to global economic pressure. Leaving a country is a basic right, as long as someone else is willing to let you in.

In the other case (in-sourcing), government is actively bringing specific types of skilled people into the country, bypassing normal immigration law and targeting very specific industries thanks to lobbyists.

You aren't screaming to have all the manufacturing jobs brought back to give Americans those jobs again as that would raise the cost of that new phone you buy every year or the new TV or appliances you get so cheaply.

Are you serious? "Have them brought back"? Like this is some kind of two-bit dictatorship? People (and the jobs they create) are free to emigrate to any country that will let them in. Good luck trying to write a law which forces job creators to remain in the US. That is truly a dark path.

By contrast, immigration policy is supposed to be "fair". But programs like H1B are anything but.

Shut up and deal with it the way the rest of the country has had to. Crybaby whiners.

The "rest of the country" certainly hasn't faced competition from H1B visa workers, more than 95% of which target the software and IT industry.

But regardless, your sentiment is clear. You are more interested in taking others down a notch because of envy, rather than being genuinely interested in public policy fairness.

Comment Re:business models (Score 1) 124

If that were true then companies would not use H1B's in the first place. Since they are using H1B's then it means that the companies care where the programmer is located.

Precisely. Very few successful and reasonably large projects are staffed by ad-hoc collections of international programmers located around the world. While it can be done, the efficiency and throughput of such projects is usually quite low. Communication overhead is usually the crippling factor there.

Offshoring an entire project is much costlier to do, and frequently management is unwilling to cede control and simultaneously unwilling to relocate. Furthermore, the same pressures in the new local market that made you leave the former local market start to creep in. Bangalore salaries for competent programmers have increased about six-fold in the last 12 years or so. The cost savings from your expensive move might suddenly evaporate.

So, companies would MUCH prefer increasing staffing levels at their current locations, especially if they can lobby politicians to make it happen without driving up salaries!

Comment Re:The title game (Score 2) 124

Funny how that (different AC) got modded down to -1 for not fitting the groupthink here. People seem think supply and demand should apply to other people, but not to them.

Not so. Most of us are just asking for the same supply and demand rules to apply to software jobs as to any other job in the US, rather than being targeted disproportionately by H1B visa policy. If demand really does exceed supply as the software barons claim when lobbying politicians, then prices for labor should be increasing, which is how the labor supply works in every other sector of the economy. But if prices are stagnant or even declining, then claims of a shortage ring hollow.

Nobody owes you a job. If you don't like the salary being offered, then nobody is forcing you to take it. Move on. But software is a global industry. The work can generally be done anywhere,, by anyone. It isn't anyone else's responsibility to ensure that your business model is as profitable as you want it to be.

Of course no one owes anyone a job. But we're not talking about "global" software supply/demand and salaries here: we're talking very specifically about the situation inside the US, because we're evaluating a question of local public policy there only (i.e., the H1B visa quotas). Gaming the system via immigration policy to keep wages artificially low in a few specific categories should be revolting to any capitalist who claims to respect the market. If immigration limits are to be enforced, they should be enforced across the board, without special consideration to special interests.

No. You can't. We offer very good salary and benefits. The people just aren't out there. There are no coders in Southern California. Every coder I know has a really great job right now and every company I know has 4-5 job openings that are unfilled. And there's nothing anyone can do except raise salaries and steal coders away from another job.

Translation: We want to hire coders but do not offer benefits that are as good as the competition. We need to import foreign workers who will work for less $$$!!! It's not our fault that employees can't afford a mortgage with our current benefits package -- that's just the cost of living in the area!
