Comment Re:High quality Indian applicants are scarce. (Score 1) 619

Further predicating a well-paying job on a degree inflames other problem areas - mainly, around poorer US citizens who cannot or could not afford an advanced degree - or any degree at all - having access to well-paying jobs IF they can demonstrate the skills and build the experience needed to satisfy its requirements. I'm one of these people, myself. I'm now on my 22nd year in this industry, and I credit a lot of luck and hard work to get to where I am now financially. A degree was never a factor in this journey.

I understand the importance of such degrees in places such as India, but I think this is an anachronism in some areas, especially if the degree comes from a place where the emphasis was on rote learning rather than independent discovery and natural knowledge maturation.

Comment Re:"At an airport" meaning Class B airspace. (Score 1) 44

Can you imagine the uproar if drones were required to equip a WAAS GPS and ADS-B Out?

The problem we pilots have with the drone-flying public is that we have no confidence that the drone-flying public have much of a concept of airspace, how to navigate it, and do so safely. Thankfully, nothing bad has happened yet - just a few newsworthy reports of near-misses and at least 1 suspected (but not confirmed, the last I read) collision between a UAS and an aircraft. Sadly, it probably is just a matter of time where a UAS and plane collides, and the UAS pilot was completely oblivious to how to actually fly.

Comment Re:"At an airport" meaning Class B airspace. (Score 1) 44

Yeah, agree. The general public isn't going to grok airspace classification or the 3D aspects of them (surface to 10k?, 500' to 10k? what???) A lot of drone operators (and that means everyone with one) got a very abrupt introduction to nomenclature, rules, and concepts that we pilots are familiar with, and part of me wonders just how many shirk their need to learn these things because they just don't take them seriously.

Comment On GitHub becoming a critical SPOF (Score 2) 227

The conveniences conveyed by GH are undeniable - ready-made code dev environments with widely-used issue and progress tracking, integration with other project management tools (zenhub, jira) and all in all eliminates and centralizes one's OSS and private project interests.

However, as more and more Internet Infrastucture-ish projects have moved to GH, either completely or in major parts, I've become worried. OpenSSL, several Apache.org projects, some OSes (Linux, FreeBSD, illumos), and so on call GH their home now, or at least use it in some substantial way. Eggs in Baskets analogies apply, and given the security landscape of things now, one must at least pause and weigh the Pros and Cons of this centralized and trusted repo for so many important pieces of code.

Comment Re:Sun alumnis (Score 2) 43

You're missing an important distinction - SmartOS is based on illumos, which was forked years ago off of OpenSolaris when Oracle decided to shut that down.

SmartOS is thus illumos, and illumos and Oracle Solaris have diverged a good bit in the intervening years.

Comment Re:PUBLIC STREETS belong to the public (Score 1) 767

Many residential streets in Takoma Park (I live just north of there; and have several friends who I visit in TP) are narrow; with cars parked on both sides and about 1.5 lanes worth of travel space down the middle. When these turn in to alternatives for primary roads because an app told people to go there, yes it becomes a problem, and more than just a quality of life problem.

First off, these streets do not have the capacity of the primary roads that people are bleeding off of, and second, people who are directed to these more constricted alternate routes are probably more likely to disregard any control signage such as stop signs and just roll through them with the rest of the blob, as well as blocking the typically small intersections when said blob comes to a halt. Never underestimate the disregard for general safety or basic traffic laws that people can have when a herd of them are forced to move through an area not designed to handle them.

Comment This is self-limiting in the long-term (Score 1) 216

So a non-CPL pilot who can only accept a split of the gas cost, they're going to (in theory) be racking up hours on a airframe faster than they normally would, which will lead to more frequent mandated inspection and overhaul events... events that their prior fares wouldn't have put any money towards. Not to mention defraying the cost of any hangaring or parking fees. I fail to see how "Uber for Planes" would work for the private pilot outside of purely opportunistic "hey, you're going my way?" one-offs.

Comment How about Jumbo frames (Score 1) 256

The article suggests things that people worth their IT salt should have already implemented, or at least investigated. Really baseline stuff there.

However one big oversight I see a lot w.r.t. backups and local networks which toss large amounts of data around are configuring jumbo frames. This is often forgotten about when throughput is getting tight.

Comment Re:dcraw is used by almost all raw converters (Score 4, Interesting) 162

I wouldn't be so generous in your detraction.

ACR, as it stands today, does not appear to be built around dcraw as you imply. It may at some point in the past used snippets or knowledge gleaned from dcraw and just might still today, but ACR is very much Adobe's own creation. In fact, one of the very articles you sort of point to by urging the OP to "google around" talks about this, with Thomas Knoll of Adobe essentially saying "Thanks but no thanks" W.R.T. Mr. Coffin reverse engineering the encryption in Nikon's RAW format.

I use Lightroom and PS CS4 on a daily basis, so I have ACR available and did some snooping. One thing that jumps out at me:

While probably not definitive, I would expect to see a salutation to Mr. Coffin and dcraw in there if there were dcraw bits present. There is one other binary installed with ACR, a library by the name of NkMiniLib.dylib. Given the name I would suppose this is a library containing the properly-licensed smarts required for ACR to decrypt Nikon NEF files. I admit that this is a hunch on my part, but I think it's a good one given the known circumstances around Nikon as a company and its RAW format - Nikon would rather you buy their Capture NX 2 software for RAW file manipulation. I can only imagine how much Adobe paid or pays for licensing the ability to do this in ACR (and by extension - in Lightroom and Photoshop.)

It is also well-known that Adobe's ACR team creates the profiles that plug into ACR for each camera, they don't lift them from dcraw. It's likely they get samples from manufacturers in advance or soon after a camera's release to divine the profile themselves for release in a future version of ACR.

So color me not convinced, regardless of what Mr. Coffin might put on his resume. In the course of "googling around" I cannot find one authoritative bit of info linking ACR to dcraw. ACR as it stands today doesn't appear to have a whiff of dcraw in it judging from some minor binary snooping... so until proven otherwise, I'd say that millions of photographers wordwide do not use his code as you might claim.

Comment PC makers and not chipset vendors? (Score 2, Interesting) 304

Assuming that the article's list of defendants is complete, it's interesting that this troll is going after companies which make finished systems, and not the companies which make the actual ethernet chipsets and MACs that go into those systems (Broadcom, Marvel, Intel, RealTek, etc)

One would think that those would be the source of any patent infringements (real or imagined) when talking about ethernet itself.

You're saying that Linux is 100% better because it can run on something that is exceedingly rare? Perhaps you might want to try considering some more run-of-the-mill use cases, such as those one run into in any data center and not just Los Alamos's. You know, things like serving, database server, backup server, storage and so on.

Comment Re:Colors in photographs (Score 3, Informative) 129

As already mentioned, the Bayer filter is part of the CMOS sensor itself. It's not a separate part that's tacked on near the end of the manufacturing process.

There is, however, a separate filter in front of the sensor on pretty much every DSLR. This is a IR cut-off filter. Naked CMOS sensors are very sensitive into the IR spectrum. This high-pass IR filter prevents deep red and IR from overwhelming the resulting image, producing a balanced red against the green and blue end of the visible spectrum.

There are several cases where one would want to modify their DSLR and have this filter removed. The primary users of this method are astrophotographers who wish to use a much cheaper DSLR on their telescopes vs. a very expensive purpose-made camera. There are a few small companies such as Hutech which can perform this service under warranty.


Nebulas and stars in particular emit light (human-visible and not) in a variety of specific wavelengths. These particular wavelengths are produced by ionized elements in the star or nebula complex. In your run-of-the-mill nebula, copious amounts of Hydrogen-alpha and doubly-ionized Oxygen tend to produce much of the light. H-alpha's emission line is deep in to the red spectrum, which the IR cut filter on DSLRs dutifully blocks from reaching the sensor. Removing this filter lets the DSLR capture additional light and detail from the nebula... stuff you wouldn't get with a stock DSLR.

If you take a stock DSLR and try to image (for example) the Horsehead Nebula, you're not going to get far because the thing emits almost entirely in the H-alpha band. Put on a camera that doesn't cut the deep red, and you'll get a result that's closer to what you'd expect.

There is a trade-off to doing this mod, of course... in that you're effectively turning your DSLR into a IR camera, and if you want it to be close to normal again, you'll need to put a IR filter on your lens.
