SanDisk Releases 512GB SD Card

khellendros1984 Re:Fahrenheit? WTHolyF? (207 comments)

ComputerWorld seems to be the source of the "1000-fold increase" quote. Then again, they also state that 512GB is "more than half a terabyte", so they're at least consistently inaccurate.

As for the temperature, the Fahrenheit scale is used on SanDisk's product page for the new card. Presumably, that's because Sandisk is an American company, and that page is marketing to a non-scientific audience. In the U.S., that means Fahrenheit would be used.

Harvard's CompSci Intro Course Boasts Record-Breaking Enrollment

khellendros1984 Re:Computers and Computer Science (118 comments)

That's true, in the theoretical sense. Algorithms can be described in English or in mathematical notation. Runtime complexity of an algorithm can be calculated by hand. Most often, we want a way to also evaluate those algorithms, to take measurements on their behavior, and to understand them more intuitively. Computers are useful for that, but only if there's have a way to give them instructions. It follows that a student must be taught the rudiments of programming to have an automated method to explore the properties of algorithms.

This is analogous to the use of scientific instruments in astronomy. Everything can be done by hand (technically), but tools make things quicker and easier. They act as force multipliers to make more things practical to do in a shorter amount of time. For astronomy, that means that the astronomer doesn't need to be a million times closer to the thing they're observing in order to see it clearly. For computer science, it means that I don't need to evaluate a billion algorithmic steps by hand.

California Tells Businesses: Stop Trying To Ban Consumer Reviews

khellendros1984 Re:Please can (275 comments)

I don't care what you smoke or don't, or where you get it. That's not the point. Neither are the spelling mistakes. The point is that obscuring your communication unclear on a communication platform is counterproductive.

Device Boots Drones, Google Glass Off Wi-Fi

khellendros1984 Re:Seems fine to me. (184 comments)

I find many of the things that people choose to *do* in a free society distasteful. That doesn't mean that I want to restrict rights or impose my will on others. I'd actually rather avoid that as often as possible. It's not my place to tell someone else what to do or think, if they're not actually hurting me. My reaction is purely emotional, and I don't like for my emotions to dictate my actions.

I don't expect respect from people that don't know me, but for something to be called a "dick move", it actually has to be an action. But go ahead and keep making the assumption that what I say on the Internet maps in a straightforward way to my actions in life. Seems to be par for the course.

Amazon Instant Video Now Available On Android

khellendros1984 Re:video is OS specific.... why again? (76 comments)

Or that the company that funded the video's production wants some assurance that a subscriber won't just tee a rental into a capture program and distribute it without charge to the public.

That's OK. Some clever person will have already figured it out for me. I don't know if they strip HDCP-protection from video and capture the stream, read it out of memory while decoding, decrypt DVR video files or what, but I've no video that I've ever looked for was actually protected by restrictive streaming requirements.

If the executives of a production company feel assurance that their stream can't be ripped in one way or another, then they're living in a fool's paradise.

Putting all of your text in the comment box would make your text more legible, and less like a word salad. Although with words like "Mecial" tossed into the mix, it makes you look like a customer of the companies you're talking about.

Text While Driving In Long Island and Have Your Phone Disabled

khellendros1984 Re:Maybe driver vs passenger doesn't matter (363 comments)

There are other scenarios where an SMS or MMS may be better. During a home invasion, when you don't want to expose your hiding place by speaking. In a situation where it would be useful to send a picture. In a location with weak signal, where a text transmission may get through even when you can't connect for a voice call. And then, you've got the cultural issues. A lot of people (especially the younger ones) barely use speech calls on their phones, any more, and a text may be the first thing that comes to mind when trying to get help.

A cell phone is a flexible device. I don't see a problem with enabling its use in whatever way we can, when it comes to helping someone in an emergency situation.

khellendros1984 Re:Seems fine to me. (184 comments)

Lose your distaste.

I'm sure that there are things in the world that you find distasteful as well, and it would be just as effective if an anonymous internet poster said to"lose your distaste" for those things. It may happen through long exposure and desensitization, but it ain't gonna be purely by your say-so.

Photography isn't a crime. Neither is staring intensely at someone and refusing to stop if they're clearly uncomfortable or ask you to. That doesn't mean that it's not a dick move.

Device Boots Drones, Google Glass Off Wi-Fi

khellendros1984 Re:Seems fine to me. (184 comments)

I don't like the idea of anyone else recording me, either (stores, etc), but I find the benefits of getting food, goods, doing my banking, etc outweigh my distaste. It doesn't have anything to do with Google Glass specifically.

because you don't have a legal leg to stand on

Why would that be the first thing that comes to mind? I'm not planning on suing someone for recording me. That would be pointless. Just because I have to put up with something to take part in society doesn't mean that I have to like it (or that I wouldn't appreciate places that share my viewpoint on the matter).

khellendros1984 Re:Seems fine to me. (184 comments)

Emphasis on "THEIR" establishments. It's their property. Same way that I could record anyone in my house or on MY property. Doesn't mean that it can't bother me when someone's gratuitously obvious about it.

Device Boots Drones, Google Glass Off Wi-Fi

khellendros1984 Re:Seems fine to me. (184 comments)

Am I in that geek's house, or on their property? When I'm in a store or a bank, I'm on their property, and they have an interest in recording me that I understand. Same with the cop; he's doing something comparatively dangerous in the execution of his duties. He's a public servant. A private citizen in a public place recording me for unknown purposes? That's unsettling. Personally, I wouldn't ask them to stop, but I'd be appreciative of a business that forbid its patrons to film other patrons without their permission.

Device Boots Drones, Google Glass Off Wi-Fi

khellendros1984 Re:You have a broken sense of responsibility. (184 comments)

An 802.11-compliant device that receives a deauthentication message is required to terminate its connection to the base station. As such, if you transmit a deauth, you didn't just "express an idea", you gave a command to a device that's required to obey it. It's like saying "I'm not responsible for the damage caused by hitting the self-destruct button; whoever wired the button to the explosives is". When YOUR actions cause something to happen that wouldn't have happened if you didn't do anything, then YOU are completely at fault.

Whoever selected wifi is negligent, but that doesn't fully absolve the deauthenticator of responsibility.

Device Boots Drones, Google Glass Off Wi-Fi

khellendros1984 Re:Great, crash the drone into things. (184 comments)

Deauthentication messages work outside wifi encryption. It's a common wifi attack to broadcast deauth messages, then record the reauthentication of clients as they reconnect to the wireless access point. For encryption with known weaknesses (like WEP), reauthentication attempts can be analyzed to discover the network key. This attack is similar, but without the goal of discovering the key.

Apparently, the 802.11 standard states "Deauthentication is not a request; it is a notification. Deauthentication shall not be refused by either party." If the device is standards-compliant, then spamming a deauthentication message should continually knock it offline.

Of course, but what's easier and simultaneously more desirable for more people? A rule asking that the one or two people likely to wear Glass take them off, or asking all the people in the area to pay attention to the little light, if they're bothered by the idea of being recorded?

As a form factor, perhaps that's true. As a platform, I like Android enough that it overcomes the downsides. My phone's as much of a tech toy as it is a practical device.

Unpopular Programming Languages That Are Still Lucrative

khellendros1984 Re:COBOL (380 comments)

That salary sounds low, depending on living expenses for your area. For that level of experience and that specialization of knowledge, I'd expect the number to be well into 6 figures, if they were working here.

Unpopular Programming Languages That Are Still Lucrative

khellendros1984 Re:Bullcrap (380 comments)

Are companies ever going to get off this fixation on specific programming languages?

About the same time that they get over the fixation on specific college degrees. I was hired as a C++ developer, but I've touched code in half a dozen languages besides that, and I didn't know a few of those before I had to use them.

In France, a Second Patient Receives Permanent Artificial Heart

khellendros1984 Re:I really don't my vital body parts to be on wif (183 comments)

The safe level varies based on the patient's physical activity at the time. Imagine that they're out swimming and someone uses their smartphone to set their heart to "going to bed" flow rate. And if the heart has a safety feature where it can read the neural signals for heartbeat speed, then why would it need to be externally controllable anyhow? Wireless access just seems like an unnecessary complication to the system.

Apple Announces Smartwatch, Bigger iPhones, Mobile Payments

khellendros1984 Disappointing (729 comments)

I'm not a giant Apple fan, but one thing that I actually liked about their strategy up to this point was keeping their phones smaller. I've had a 4.7" phone, and that was almost too large for my (admittedly small) hands. I've got a 5" screen now, and it's notably difficult for me to use. I'm pessimistic about my future upgrade options at this point, if even Apple is jumping on the mega-sized-phone bandwagon.

Lenovo to offer $200 budget tablet

khellendros1984 khellendros1984 writes  |  about 3 years ago

khellendros1984 (792761) writes "Amazon's not the only big-name company planning on a budget-level tablet release; Lenovo recently announced their Ideapad A1 tablet as competition. It includes a 1GHz Cortex A8 CPU, along with other features more commonly seen on higher-priced tablets, such as dual cameras, bluetooth, GPS, wifi, and a MicroSD slot. Is this the start of the Android tablet price avalanche?"
