Comment Re:Why "still"? (Score 1) 32

I worked with a gentleman who I believe discovered rowhammer in parallel with the research which led to the the original paper on the subject (i.e. we were aware of this issue before "rowhammer" was a term). His discovery was made while writing diagnostics for machines in the class of the largest servers and (non-cluster) supercomputers.

So, definitely not just a laptop issue.

It's not an exact replacement, as it's more for people who want to actually manage a budget and adjust their spending proactively rather than just monitor where their money went, but what you're looking for is YNAB (You Need A Budget). https://www.youneedabudget.com...

On top of providing budgeting and transaction import (automatic or manual), there's actual human-based support included in the subscription.

I've been using the previous version of the software (pre-subscription, but lacking some newer features such as automatic import) for over five years, and it's been a game-changer for effectively managing my money.

Comment Why can an app access the SSID in the first place? (Score 1) 39

Aside from some networking-related apps, why would an app be allowed to know the device's SSID in the first place?

SSID geo-mapping is a well-known and effective technique for determining device location. Apple and Google are not unaware of this, and to whatever extent they claim to care about privacy this loophole should have been sewn shut long ago.

Comment But why? (Score 1) 65

OK, I get it, legalizing use/possession of pot is what all the cool jurisdictions are doing, and that past convictions almost certainly fell hardest on certain minority demographics.

But... weren't these convictions for a violation of the law at the time of the offense? So the individuals willfully and knowingly (in most cases) breached the law, were tried with all the same rights of due process, representation, evidence standards, and appeal as for any other criminal offense, and were convicted.

I don't understand how we can justify removing a record of willfully criminal behavior. It happened, they were caught, and convicted; that it wouldn't be a crime if it happened today is irrelevant.

Absolutely. My wife ordered an Impossible Burger at a sit-down restaurant. I, ever the skeptic, tried a bite and I was amazed at how convincing it was. If you had served it without telling me what it was I wouldn't have had any reason to doubt its animal origin, and would have thought it one of the better burgers I'd had in a long time. I'm sure part of the convincing nature was careful preparation, but dang if it wasn't a good burger.

Once they perfect this thing so it can be prepared at home with great results I'll have no qualms about switching to it.

Comment Realized this some time ago (Score 1) 253

In the past few years I started monitoring my peak bandwidth used, which almost exclusively occurs when watching streaming video from Netflix. At the times I measured the number from the article (under 7Mbps) appears about right for 1080. We only have a single TV and otherwise maybe stream a bit of Youtube/etc. to our phones or laptops/desktops. Even then we're rarely doing more than one of any of those (TV/phone/laptop) at a time. On the occasions when I work from home Skype voice calls don't add significantly to my use, and all my work is with terminal sessions via ssh, and a small bit of HTTP traffic, so that doesn't add much either.

Comcast's minimum speed on an Internet-only package in my area is something like 25 Mbps; this more than adequately covers my use cases so I dropped my plan down to that. Comcast and CenturyLink Fiber keep promoting a switch to their high-end packages but I haven't heard a justification as to why I need it. Heck, the salesguy at the Comcast store even agreed with me once I provided him my observations, and happily downgraded my service.

The only downside I've been able to detect is my OS updates appear to download a little on the slow side. However as those updates are mostly a background task, it really has almost zero impact on me.

I dunno. I sure as heck wanted to buy a Cadillac CTS after seeing Matrix Reloaded. Cadillac certainly payed for product placement (i.e. advertising), and the car was so cool looking that it fit the movie perfectly.

Never mind I was in no financial position to buy one, but man, if I had been 10-15 years further into my career...

Basic Text Editor: vim
IRC/Messaging Client: pidgin, xchat, epicII, in that order

Office Suite: OpenOffice, because there's no other realistic choice outside of Google Docs or Office 365.

Video Player: Don't use.
Music Player: Don't use.
Photo Viewer: eog, because I don't know what else is out there. Not a great choice, admittedly.

Exactly. I ran some back-of-the-envelope calculations on this 3.5 years ago in another Slashdot thread. https://slashdot.org/comments....

And because we're presumably too lazy to click that link, I'll paste it below for your reading pleasure...

This is why: http://what-if.xkcd.com/17/ [xkcd.com]

There simply isn't enough solar power delivered to the surface of the aircraft, even at 100% conversion efficiency, to move people and luggage using only available sunlight.

Google tells me direct illumination to a surface perpendicular to incoming full intensity sunlight is about 1.4 kW per square meter. Google also tells me that the wing surface area of a 747 is around 5500 square feet. Only half of the 747 wing is directly illuminated by sunlight at any given moment, but the surface of the fuselage could be covered with photocells as well, so 5500 square feet overall is probably a decent estimate for the directly illuminated surface area of the aircraft as a whole. And for hand-wavy purposes lets assume that the entire surface of the 747 is perpendicular to the incoming sunlight (i.e. a planar plane... pun totally intended). And that we have perfectly efficient photocells giving us 100% conversion efficiency. Running the math, this gives us around 715kW under bright direct sunlight, or about 959 horsepower -- the equivalent of 1.5 2012 Ford Shelby GT500's.

Each engine of a 747 generates around 15,000 horsepower at cruise, and around 30,000 at takeoff, and a 747 has four engines. So you need around 125 times the power generated by a perfectly efficient perfectly illuminated solar-powered 747 to get said plane off the ground, and around 65 times the power for cruising. And then you could only fly it in the middle of the day near the equator.

There's plenty of small tech-oriented business around here as well.

Comment Family, hobbies, and charities, oh my (Score 1) 842

I'd pay off my mortgage, remodel the house a little bit to make it more usable, and look around for a reasonable lightly used car to replace my wife's aging vehicle. Then I'd help my siblings (and my wife's) out by paying off mortgages, school debt, and the like. I'd set up some sort of financial structure to make sure that my wife and, should they come along, my children would live without financial stress for the rest of their lives after I pass away. And a goodly chunk right off the top would go to my church and another religious organization that was very important in my life.

After that, I'd take up a bit of travel. I'd take lots of guitar lessons and buy more music equipment than someone of my skills can reasonably justify. I'd set up an endowed foundation to perpetually help fund the type of charities and other organizations that I think need supporting. And maybe get back to taking dance lessons regularly. I'd go to more concerts, and pay for better seats and the occasional meet-and-greet. And I'd spend time developing an open-source project idea that I've had for several years. And I'd probably pay someone else to mow the lawn, tend to the flower garden, and clear the driveway of snow.

Comment 36 hour bus commute (Score 1) 654

This article caused me to wade through my major metro area's online system to plan a trip between my new house, which is within blocks of a suburb park and ride facility, to my work, in the same town. By car this is a 10 minute trip, maybe, depending on the state of traffic lights.

At first the online system told me the trip was impossible at the time of day I specified. So I dug deep into the site and pieced together what appears to be the only possible set of routes that connects these locations without sending me to the downtown core for connections. After much digging I found that, for all practical purposes, the route is indeed impossible. It appears that, due to one key route only running in the very early morning and late rush hour, it would take me around 36 hours to commute each way.

If I took the bus all the way to the downtown core then back to work I still can't do it, because the morning bus to my work stops running before I arrive downtown.

Yeah. Not happening.
