Ask Slashdot: What's the Most Often-Run Piece of Code -- Ever?

MarcAuslander the windows interrupt handler (533 comments)

I agree this is impossible to measure but..

I'd guess the first level interrupt handler in windows (most of which is in C by the way) would be high on the list.

(Most processors go to sleep rather than running an idle loop, which sort of rules that out).

When Opting Out of Ad Tracking Doesn't Opt You Out

MarcAuslander Adblock is your friend (193 comments)

The cynic in me says that any request you make about your email address just makes that a more valuable address!

Ablock, on the other hand, seems to do the trick pretty well for many people. Adblock plus actually right now - but there is a growing controversy about it.

Condensation On Your Beer != Good

MarcAuslander How do you know? (275 comments)

People always claim that bad beer tastes like piss. And I always wonder how they know! Which reminds me of a childhood memory. We were in the Catskills in what was then called a bungalow colony. One day, for some reasons, the owner had to siphon some gas, which he started by sucking on the hose. My dad asked what it tasted like - it tastes like manure he said. Once we were away, my dad wondered aloud how he knew.

Removed java a while ago. I haven't found a site a cared about that needed it. We should all pressure any sites that still use it to get off it.

Are Lenovo's ThinkPads Getting Worse?

MarcAuslander T530 Keyboard (271 comments)

This was the beginning - the "new" keyboard on the T530 and brothers. It's OK - but not the wonder that my ancient T40 had. I simply make more typing errors, for a bunch of subtle reasons.

Google Loses Santa To Bing

MarcAuslander Marketing to cover weakness (153 comments)

The story prompted me to look at bing maps. Very first direction request produced a poor route. When dragging the route to change it gives less time and distance, you know it's not the source to use! There is no way to reset a drag! etc. etc. I'll stick with google.

But one wonders how this government agency was co-opted.

Ask Slashdot: Best File System For Web Hosting?

MarcAuslander ext4 unless there's a good reason not to. (210 comments)

The obvious argument for ext4, the current ext version, is that it's been around a long time and is very solid. I'd only use something else if I knew the performance of ext4 would be an issue.

WHMCS Data Compromised By Good Old Social Engineering

MarcAuslander Security Questions deemed dangerous (87 comments)

It has been pointed out many times that the security question system is dangerous if the user does what he's told. It is in general easier to find out what someone's high school mascot was than to guess his password! My approach it to provide nonsense answers I can retrieve for all such question. No one's going to guess that my mother's maiden name was bottleofbitsofstuff for example. You can use the same answer for all questions if they let you, or use obvious variants otherwise.

Stroustrup Reveals What's New In C++ 11

MarcAuslander Assigning new values to constants can be useful! (305 comments)

I was amused by the comment "If that incr(0) were allowed either some temporary that nobody ever saw would be incremented or - far worse - the value of 0 would become 1. The latter sounds silly, but there was actually a bug like that in early Fortran compilers that set aside a memory location to hold the value 0. "

Back then, I wrote Fortran subroutines which took computed dimension arrays by declaring the arrays with crazy bounds, numbers I hoped would never be used as constants, and then "assigning" the real bounds to the "constants".

Those were the good old days.

Epsilon Breach Affects JPMorgan Chase, Capital One

MarcAuslander Chase Letter a perfect phishing template! (180 comments)

Got my Chase letter. It warns about not sending information by email. Nothing about not clicking on links. In fact, it contains the lines:

The security of your information is a critical priority to us and we strive to handle it carefully at all times. Please visit our Security Center at chase.com and click on "Fraud Information" under the "How to Report Fraud." It provides additional information on exercising caution when reading e-mails that appear to be sent by us.

chase.com is a link!

All a phisher needs to do is send this exact email, pointing to a dummy Chase page, and encourage the victim to log in when he reaches it.

Clearly they are either very stupid or really just don't care. I'll go for the latter.

Microsoft Makes Chrome Play H.264 Video

MarcAuslander WIndows 7 Only (535 comments)

As with the firefox extension, this only works on Windows 7. So it in no way makes H.264 universally available.

Scientifically, You Are Likely In the Slowest Line

MarcAuslander William Feller taught this almost 50 years ago. (464 comments)

In An Introduction to Probability Theory and Its Applications by William Feller, published before 1968, Feller describes this effect, pointing out that we mentally average over time, not occurrences, and spend most of our time in the slow line.

New Heat-Reduced Magnetic Solder Could Revolutionize Chip Design

MarcAuslander Isn't that how we make cold joints (103 comments)

In soldering 101 I learned that if you put hot solder on cold metal, the solder doesn't really wet the joint, and you will get early or immediate failure of conductivity. You can even accidentally create a diode. So why will this work?

New York Times Site Pop-Up Says Your Computer Is Infected

MarcAuslander Seen in a google search (403 comments)

A few days ago, my wife hit the same thing following a link in a perfectly benign google search result! she would have had no idea how to untangle this by herself, since I had failed to turn off firefox restore on error so killing and restarting firefox got right back to the problem.

Microsoft's Free AV App May Be a Non-Starter

MarcAuslander The discussion misses the point (maybe) (251 comments)

Infected windows machines are a plague on the internet. Many of these presumably have no useful anti-malware running. Microsoft takes lots of heat, as the comments above prove. So Microsoft decides that trying to sell anti-malware won't work, but maybe giving it away, and I assume bundling it, will get it widely deployed. And take some heat off Microsoft for shipping vulnerable stuff. If this happens, and it works at all, it will be a great improvement to the current mess. To put it differently - it's clearly impossible to make an OS bug proof - so an OS ought to contain defenses against malware out of the box.

Dealing With ISPs That Use NXDomain Redirection?

MarcAuslander This is about DNS, not routing. (264 comments)

Lots of misunderstandings in the replies. First - the most common offender is the Hotel's local internet service. Second - this is about DNS, not routing. Windows tries all the DNS servers at once and believes the first positive answer. The DNS servers in the story are the onces the Hotel gave you on the real interface, and the ones VPN gave you on the VPN interface. You can often make this go away by using the advanced settings in the network folder to order the VPN adapter first as a service provider. Failing that, I know of no solution that doesn't require messing with the DNS server entries in the real adapter.

Email-only Providers?

MarcAuslander Email Forwarding (601 comments)

Most registrars (I use godaddy) provide email forwarding. I have a domain for email - I can forward any id in the domain to anyplace. There is a wildcard address for all ids not explicitely forwarded. Most get forwarded to either my or my wife's gmail account.

What do WiFi signal looks like?

MarcAuslander MarcAuslander writes  |  more than 2 years ago

MarcAuslander (517215) writes "Have you ever wondered what the WiFi signal looks like around your office, school, or local café? In this video, Timo Arnall, Jørn Knutsen, and Einar Sneve Martinussen show you the invisible. And they pulled this off by building a WiFi measuring rod, measuring four meters in length, that can visualize WiFi signals around Oslo, Norway with the help of long exposure photography."
