+ - Research Shows RISC vs CISC Doesn't Matter 1

Submitted by fsterman
fsterman (519061) writes "The power advantages brought by the RISC instruction sets used in Power and ARM chips is often pitted against the X86's efficiencies of scale. It's difficult to asses how much the difference between instruction sets matter because teasing out the theoretical efficiency of an ISA from the proficiency of a chip's design team, technical expertise of its manufacturer, and support for architecture-specific optimizations in compilers is nearly impossible . However, new research examining the performance of a variety of ARM, MIPS, and X86 processors gives weight to Intel's conclusion: the benefits of a given ISA to the power envelope of a chip are minute."

sciencehabit (1205606) writes "These images of a cardboard cutout of a cat were made with light that never touched the object. The technique works a bit like holography, in which a light beam that shines through an object overlaps and interferes with an identical one that passes by it, and that interference is used to encode a 3D image. Besides being really cool, the technique makes it possible to make an image of an object using a color of light that would normally pass through the thing."

They claim that this data could be used to provide drivers with a warning if their vehicle might be getting too close to another vehicle. It will also be necessary to make driverless cars more reliable.

I wonder what other uses this information could have."

jones_supa (887896) writes "Good Old Games is prepping to bring another medium into its trademark DRM-free digital distribution platform: movies! To get things rolling, the shop is already serving a couple of dozen indie films as we speak. Currently the bigger studios are waiting for someone else gnaw on the rock and prove that selling DRM-free movies works. "Their reaction was kind of funny because ... they know that DRM doesn't work because every single movie is on torrent sites or illegal places at launch or even before," Marcin Iwinski, CD Projekt RED and GOG joint-CEO reminds us. GOG plans to bring more movie titles on a weekly basis."

Comment: Hiring Programmers is Hard (Score 1) 379

I like to have developers bring in some code they've written and go through it. It's amazing how many developers are just not good at interviewing... until we start looking at code. Oh, and the fakers, well, they seem to never bring code to the interview.

As far as tests go, we use them for people fresh out of school because there is a huge difference between passing a CS class and actually being able to apply that knowledge.

If you like GTD, the best organizer ever is Emacs Org Mode. Because Org Mode uses plain text files for storage, you can use git for storage and have very meaningful history tracking and sync across devices. There are even tools for syncing to third party calendars (i.e. Google) and devices.

There is no difference in parties in how they sell their platforms. Republicans use fear of foreign powers, fear of government, fear of immigrants and fear of loss of financial independence. Democrats use fear of racists, fear of religious institutions, fear of loss of government subsidies and fear of foreign powers.

The biggest difference really is how they view government: Republicans pander to those that fear government and Democrats pander to those that fear the lack of government. The message of fear was beaten by a guy selling hope.

On developers never having access to production:

In many cases, developers are the only people who understand the full application, and in many cases are the only people who can actually troubleshoot a botched install or figure out why things aren't working right in production. Yes, you are suposed to have some kind of QA or staging environment and you are not supposed to deploy bad code, but sometimes things go sideways. In these cases, only a developer who knows the code and any integration issues will be able to figure out what went wrong. Acting like developers should *never* have access to production is a lot like saying "the mechanic should never have access to my car's engine, ever". It makes sense 99.9% of the time, but there is a .1% where your engine is broken and the mechanic can't fix it without getting under the hood. Yes, Mr. System Administrator you can change your oil, rotate tires, and even change wiper blades but fixing a spun road bearing or smoked transmission solenoid is flat out.

On Developers and Access Rights:

There are a lot of developers who don't understand the computer they are developing software on. Usually, they are very BAD developers. Take for instance, a webdev who doesn't know Apache. Instead of using built in tools like mod_rewrite, the developer will build their own tools to do what is built in to apache. Good developers know their platform, often at a level that is much deeper because they take time to read code or API and config documentation so they understand the toolbox they are working with. Often a single line of configuration is more powerful than 1000's of line of code. Developers need to be administrators on at least their developement environments... usually extended to staging there is a large difference in scale between development (a VM on my laptop) to staging (multiple servers) and production (hundreds of servers).

On installer driven software:

It doesn't matter if you use installshield, roll your own RPMs or use Salt, Chef or Puppet. Any way you go you should do everything you can to automate installation. When you automate you reduce the chance of human mistakes in installation process. If you do installation automation right, then a deploy to production can be triggered by anyone with appropriate authority or any automated process with appropriate authority. Having people sit at the console and install software manually should be a red flag that the software you are buying sucks or is incomplete.

In Enterprise-Grade software:

Installatioin should be automated to the maximum extent possible, using the appropriate operating system installation tools. Documentation for the upgrade and install should be clear enough that a non-developer can successfully install and test the installation. Install activity should be logged, so that if something does go wrong, it can be figured out later.

Even if they met all the requirement to bill as emergency band-aid application, you still feel it's fraudulent? You're not a fan of rule-of-law, are you

The intent of the emergency band-aid is to compensate for the difference in cost between the emergency room and a primary care physician's office. Very rarely would a primary care office meet the requirements of being an emergency room... but the descriptions of the procedure may be the same.

I'm actually a big fan of the rule of law. The problem with healthcare billing is that is too easy for care providers to deceive the payer.

If there are two legal, legitimate ways to code for a given procedure, why would a clinic not bill for the more expensive of the two? Medicare - not the hospitals - sets the reimbursement rates and defines the codes. If they didn't intend for the higher code to be billable, they should have written the definition so that it wasn't.

If a care provider is doing additional services with the only objective being getting paid more and not treating the patient, it is fraud - even if it just five percent extra.

The ones that really get me are where the care provider does a little creative coding:

Doctor applies band-aid to cut. Bills as primary care band-aid application. Is authorized $26.
Doctor applies band-aid to cut. Bills as emergency band-adi application. Is authorized $921.

The problem with all of this is that doctors are being paid for proceedures instead of being paid to make people better. If you pay for proceedures, there is a reverse incentive to make people well (or in other words, keeping people sick is good for business).

Going the speed of light is bad for your age.
