Comment Re:F6 behaviour (Score 1) 415

In previous versions, when you pressed F6 it selected the address bar.

You can still press Control-L (for Location) to select the address bar. Similarly, Control-K selects the search bar.

Yes, I know that F6 selects the location field in IE and the File Explorer on Windows as well, so F6 would be more consistent. I'm just saying that there is still a keyboard shortcut to select the address bar.

I used to work in the HDD industry, and am very familiar with the seek algorithms used. Sorry, but your description of the move algorithm is completely wrong. Modern control implementations collect information about the actual output of the system (such as position) relative to the desired output (the target position) and act on it in real-time.

Modern HDDs (as in, anytime in the last 15+ years) have 'servo tracks' written on the disk. These are radial spokes of distance information encoded on the disk. Today's drives may have as many as 500 or 1000 of these servo spokes. The head is able to read these as it seeks across the disk, so it knows where it is during the seek. There is no 'stopping, checking where you are and making an adjustment.' It's more along the lines of 'checking your position as you move, and adjusting the voice coil voltage to give the optimum velocity and acceleration to land in the right spot as quickly as possible.'

There is an enormous amount of effort that goes into reducing the amount of vibration generated by the drives themselves, as well as minimizing the drives' sensitivity to external vibrations. However, there are specs for what the drives are able to handle, worst-case. By reducing the amount of vibrations they are subjected to, they will naturally perform better.

Being Slashdot, we need a car analogy, right? Cars are made to deal with headwinds and still get acceptable gas mileage, but removing the headwind will increase a car's gas mileage.


Submission + - No plans for Windows 7 in 2009

Samarin writes: Microsoft has clarified that they have no plans to ship a new version of Windows in 2009: "We are not giving official guidance to the public yet about the next version of Windows, other than that were working on it. When we are ready, we will provide updates." Seems like Microsoft heard the laughing all the way in Redmond, and decided to retract Ben Fathis's comments (previous /. coverage).

Submission + - Turns Out Google Really Does Listen

SamThomp writes: "There's a perfect Google underdog story going on right now. It goes like this: A college student named Aaron Stanton has an idea he thinks Google will love. He tries to get in touch via phone, e-mail, and their web forms with no luck. Then, spurred by his father nearly dying of an embolism near Christmas, he takes a chance and flies to Mountain View, CA without an appointment, intending to sit in their lobby "like a spoiled child" until he gets a chance to meet with someone. He's been there about three days, now.

Here's where it gets interesting. He creates a website called, and uses Google Video to document his journey in hopes that it might be seen by someone at Google and they'll show pity. At first he's turned away (links to Google Video) at the door and doesn't get a chance to talk to anyone. Then, apparently someone in Google does notice the website and it spreads — word of mouth — inside of Google like wildfire; 600 people visit the site in two hours from inside of Google's headquarters at Mountain View.

Then, late last night — three days into his trip — the guy gets an e-mail with the subject line, "We can hear you :)" that says they're willing to listen to him. No meeting for sure yet, but a step in the right direction.

It's like "actual" reality TV. :) If you're looking for an interesting story to pay attention to for the week, it'll be interesting to see how this turns out. So far, Google seems to be living up to their image of being a large company that's open to ideas. As far as I'm concerned, best of luck to them both."

Submission + - Open Source Online Order Entry - Suggestions?

kwandar writes: "Our company is a small/medium sized software developer that sells software around the world. The order/sales system is outdated (DOS based), with limited capabilities. We need to replace this with one that provides strong CRM/sales, customer support, bug reporting/tracking, order entry/accounting reporting, and perhaps hooks into licensing software. Ideally it would be web based so that all ordering can be done over one system, whether by a customer, ourselves internally, or our foreign distributors. I'd like input from Slashdot users, as many of you have already been through this and hunted down software that worked in a software sales environment. Is there an all-in-one solution, or several solutions that can be recommended (open source preferred)?"

Submission + - A real anti-phishing token?

Edouard writes: Gemalto, probably the world's oldest and largest security token provider, and a world leader in digital security, has recently released a SecurityMeetsSimplicity mini web site, and now this video on YouTube and DailyMotion. A 100% Plug'n'Play USB token that does mutually authenticated SSL between itself — yes, not the browser, the token itself! -and remote web sites: by tunneling user credentials within a device-to-server SSL tunnel, you can pretty much say good bye to Phishing & Pharming issues, as the token will not release your security info unless it trusts the server. To me, this is a pretty new approach, what does the Slashdot crowd think?

Submission + - Development Walkthrough for Cell Phones

elhaf writes: "This post gives a complete walkthrough for getting started in Java cell phone development for your Sony Ericsson non-smartphone cell, on the Cingular network. It gives troubleshooting tips and a concise step-by-step guide to getting started developing for these phones. The SDK includes a cell-phone emulator that runs on the PC which is cool, so you don't even need the actual phone to get started. There's a picture of the emulator running at the top of the article."

Submission + - TSA can't figure out security certificates

markgo2k writes: "The Washington Post reports that TSA has taken a new website live that people who are wrongly on the famous "no-fly" list can protest their status. Unbelievably, the website uses a self-signed certificate (and some have reported that you can submit forms insecurely as well). Perhaps contractor (Desyne Web Services, Inc. nor whoever was managing them ever actually tested the site or figured that flashing red certificate error warnings were something that might not be okay on a site that asks for name, address, height, weight, date of birth, hair color, eye color, passport number, birth certificate, drivers license number, military id number..."
