• DIY Coffee Table Arcade Hides Retro Gaming Inside

  - by Jason Fitzpatrick

  Last week we showed you a nifty man-cave arcade-in-coffee-table build that was a bit, shall we say, exposed. If you’re looking for a sleek build that conceals its arcade-heart until it’s game time, this clean and concealed build is for you. Courtesy of IKEAHacker reader Sam Wang, the beauty of this build is that other than the rectangle of black glass in the center of the table–which could just as well be a design accent–there is no indication that the coffee table is a gaming machine when not in use. Slide out the drawers and boot it up, however, and you’re in business–full MAME arcade emulation at your finger tips. Hit up the link below to check out his full photo build guide.

• Would You Pay for Smartphone OS Updates? [Poll]

  - by Jason Fitzpatrick

  For most phone ecosystems, manufacturer/carrier provided updates are few and far between (or outright nonexistent). To get access to mobile OS updates, would you open your wallet? While iPhone users are used to regular (and free) OS updates, the rest of us our largely left out in the cold. Over at ExtremeTech, Ryan Whitwam argues that we should be willing to pay for smartphone OS updates. The core of his argument is updates cost money and there is no financial incentive for carriers like Sprint and Verizon to turn back to their supplies (say, Motorola or LG) and pay them to provide an update pack for a phone they stopped selling last quarter. He writes: It might be hard to swallow, but the manufacturer of your phone is out to make money for its shareholders. The truth of the matter is that you’re not even the customer; the carrier is. Carriers buy thousands of phones at a time, and unless the carrier wants an update, there won’t be one because there is no one else to pay for it. Imagine if, instead of burning money for little or no benefit, an OEM actually had a financial incentive to port ICS to its older devices. Instantly, the idea of updating phones goes from the customer service back-burner to the forefront of a company’s moneymaking strategy. If the system proves a success, carriers could get involved and have a taste of the update fees as compensation for deploying the update over the air. This is more viable now than ever before thanks to the huge number of Android phones in the market. Samsung, for example, has sold over 30 million Galaxy S II phones since last summer. It has just started rolling Android 4.0 updates out to some countries, but most users are still waiting. If it charged just $10 for access to the update, that would be $150 million if only half of all users wanted an official update.

• How do I access a shared folder using credentials other than the ones I logged in with?

  - by George Sealy

  I have a lab full of Windows 7 machines, and a shared login (user360) that all my students use. I also have a shared folder that they can all have read/write access to (for moving files around easily). My problem is that I also want to be able to create a shared folder for each student for submitting assignments. I can set up a shared folder with permissions for just a single user, and not the 'user360' account. The problem is, when I'm logged in as user360, and I try to open the 'StudentA', Windows never asks me for alternate credentials, it just refuses access because the user360 account is not allowed access. Can anyone suggest a fix for this?

• How Curiosity Took Its Self Portrait [Video]

  - by Jason Fitzpatrick

  There was enough confusion among the public as to how exactly the Curiosity Rover was able to photograph itself without the camera arm intruding into the photo that NASA released this video detailing the process. For those readers familiar with photograph blending and stitching using multiple photo sources, this should come as no surprise. For the unfamiliar, it’s an interesting look at how dozens of photos can be blended together so effectively that the arm–robotic or otherwise–of the photographer can be taken right out.

• How Lead-Acid Batteries Work [Video]

  - by Jason Fitzpatrick

  Every morning when you go out and start your car, you’re pulling power from a lead-acid battery. But how exactly do they work? In this informative video we see how lead plates and sulfuric acid provide the power your car craves. Courtesy of Engineer Guy Video: Bill explains the essential principles of a lead-acid battery. He shows the inside of motorcycle lead-acid battery, removes the lead and lead-oxide plates and shows how they generate a 2 volt potential difference when placed in sulfuric acid. He explains how the build up of lead sulfate between the plates will make the battery unusable if it discharged completely, which leads him to a description of how to make a deep cycle battery used for collecting solar energy.

• find the next due date after today within a group in an Excel PivotTable

  - by Dennis George

  I have got a table set up in one sheet with "transactions". Each row contains a name of a vendor, the amount owed or paid depending on transaction type, and the due date/transaction date. Here is some simplified sample data: Vendor Date Invoice Payment Vendor A 6/30 $200 Vendor A 6/30 ($200) Vendor B 7/5 $500 Vendor B 7/5 ($500) Vendor C 10/28 $50 Vendor A 10/30 $100 Vendor C 11/15 $50 I have already built a PivotTable from that table to group these transactions by vendor and sum the remainder owed. What I'm trying to figure out is how to, for each vendor, get the next due date (min date of the group, excluding dates < Today()), or if there is no next due date then I want to see the max date for that group. Here is what my PivotTable looks like, plus the date column I'd like to add (assuming Today() = 10/23): Vendor Date Owed Vendor B 7/5 - Vendor C 10/28 $100 Vendor A 10/30 $100 I know calling it next due date might not be so accurate if I end up with the date of a payment in that column, but I'm ok with that. tl;dr : I want to find the next earliest date within each group, or the last date. How do I do this?

• Undocumented Gmail Search Operator Ferrets Out Large Email Attachments

  - by Jason Fitzpatrick

  If you’re looking for a way to quickly find large email attachments in your Gmail account, this undocumented search operator makes it simple to zero in on the hulking attachments hiding out in your inbox. To use the search operator simply plug in “size:” and some value to narrow your search to only emails that size or larger. In the screenshot above we searched for “size:20000000″ to search for files roughly 20MB or larger (if you want to be extremely precise, a true 20MB search would be “size:20971520″). If you’re looking to clean up your Gmail account this is a nearly zero-effort way to find the biggest space hogs–in our case, we found an email packed with massive PDF files from a 5 year old project that we were more than happy to purge.

• Uploading.to Uploads Files to Multiple File Hosts Simultaneously

  - by Jason Fitzpatrick

  If you’re looking to quickly share a file across a variety of file hosting services, Uploading.to makes it a cinch to share up to 10 files across 14 hosts. The upload process is simple. Visit Uploading.to, select your files, check the hosts you want to share the file across (by default all 14 are checked), add a description to the collection, and hit the Upload button. Uploading.to will upload your file to the various hosts; during the process you’ll see which hosts are confirmed and which have failed. We had 2 failures among the 14 hosts which still left the file mirrored across a sizable 12 host spread–not bad at all. When you’re ready to share the file hit the Copy Link button at the bottom of the screen and share it with your friends. They’ll be directed to Uploading.to and will be able to select from any of the hosts the file was successfully mirrored across. Uploading.to is a free service and requires no registration.

• More than 3 seconds "Initial Connection" time (webpagetest.org)

  - by George Tasioulis

  I'm having a weird issue with a vBulletin forum, on a 2? Xeon E5645 w/ 16GB RAM, cPanel and LiteSpeed webserver; It takes too long to start loading... When I tested it with webpagetest.org I saw that for every request there's a 3 second "Initial connection" delay, which I don't know why is happening. Here's a screenshot: CPU Load is between 0.03 and 0.05, I've got several GB of free RAM, practical no I/O activity, and this delay can occur even with only one visitor on the forum. Where do you suggest I start searching? What could be the reason for this kind of delay? I don't think it's the webserver, or the forum because there's another website on the server (total 2 sites) which is WordPress based, and has exactly the same issue with the 3 second initial connection delay. I believe it's OS related, but need a clue on where to start looking. Thanks in advance :)

• DC Comics Identifies Krypton on the Star Map

  - by Jason Fitzpatrick

  This week Action Comics Superman #14 hits the stands and DC comics reveals the actual location of Kyrpton, delivered by none other than beloved astrophysicist Neil Tyson. Phil Plait at Bad Astronomy reports on the resolution of fans’ long standing curiosity about the location of Krypton: Well, that’s about to change. DC comics is releasing a new book this week – Action Comics Superman #14 – that finally reveals the answer to this stellar question. And they picked a special guest to reveal it: my old friend Neil Tyson. Actually, Neil did more than just appear in the comic: he was approached by DC to find a good star to fit the story. Red supergiants don’t work; they explode as supernovae when they are too young to have an advanced civilization rise on any orbiting planets. Red giants aren’t a great fit either; they can be old, but none is at the right distance to match the storyline. It would have to be a red dwarf: there are lots of them, they can be very old, and some are close enough to fit the plot. I won’t keep you in suspense: the star is LHS 2520, a red dwarf in the southern constellation of Corvus (at the center of the picture here). It’s an M3.5 dwarf, meaning it has about a quarter of the Sun’s mass, a third its diameter, roughly half the Sun’s temperature, and a luminosity of a mere 1% of our Sun’s. It’s only 27 light years away – very close on the scale of the galaxy – but such a dim bulb you need a telescope to see it at all (for any astronomers out there, the coordinates are RA: 12h 10m 5.77s, Dec: -15° 4m 17.9 s). 6 Ways Windows 8 Is More Secure Than Windows 7 HTG Explains: Why It’s Good That Your Computer’s RAM Is Full 10 Awesome Improvements For Desktop Users in Windows 8

• Secondary IP (eth0:0) acts like main server IP

• Pac-Man Hiding Spot Makes High Scores a Snap

  - by Jason Fitzpatrick

  This interesting bug (feature?) in the original Pac-Man game makes it easy to hide from the ghosts, ensuring a long-lived and well-fed Pac-Man. Check out the video above to see the black hole you can park Pac-Man in to avoid assault by the ghosts. There’s two big caveats with this trick: first, it only works in the original game (spin offs and modern adaptations won’t necessarily have it but the original machine and MAME implementations of it will). Second, it doesn’t work if the ghosts see you park yourself there; you need to slip into the spot our of their direct line of sight. Still craving more Pac-Man goodness? Check out these cheat maps that map out all the patterns you need to follow to sneak through every level unmolested by ghosts.

• Square Reader Modified to Record Off Old Reel-to-Reel Tape [Video]

  - by Jason Fitzpatrick

  The Square Reader is a tiny magnetic credit card reader that has taken the mobile payment industry by storm. This clever hack dumps the credit card reading in favor of snagging the audio from old music reels. Evan Long was curious about whether the through-the-headphones interface of the Square Reader could be used to read audio data off old magnetic recordings. With a very small modification (he had to bend a metal tab inside the reader to allow the audio tape to slide through more easily) he was able to listen to and record audio off old reels.

• Active Directory Time Synchronisation - Time-Service Event ID 50

  - by George

  I have an Active Directory domain with two DCs. The first DC in the forest/domain is Server 2012, the second is 2008 R2. The first DC holds the PDC Emulator role. I sporadically receive a warning from the Time-Service source, event ID 50: The time service detected a time difference of greater than %1 milliseconds for %2 seconds. The time difference might be caused by synchronization with low-accuracy time sources or by suboptimal network conditions. The time service is no longer synchronized and cannot provide the time to other clients or update the system clock. When a valid time stamp is received from a time service provider, the time service will correct itself. Time sync in the domain is configured with the second DC to synchronise using the /syncfromflags:DOMHIER flag. The first DC is configured to sync time using a /syncfromflags:MANUAL /reliable:YES, from a peerlist consisting of a number of UK based stratum 2 servers, such as ntp2d.mcc.ac.uk. I'm confused why I receive this event warning. It implies that my PDC emulator cannot synchronise time with a supposedly reliable external time source, and it quotes a time difference of 5 seconds for 900 seconds. It's worth also mentioning that I used to use a UK pool from ntp.org but I would receive the warning much more often. Since updating to a number of UK based academic time servers, it seems to be more reliable. Can someone with more experience shed some light on this - perhaps it is purely transient? Should I disregard the warning? Is my configuration sound? EDIT: I should add that the DCs are virtual, and installed on two separate VMware ESXi/vSphere physical hosts. I can also confirm that as per MDMarra's comment and best practice, VMware timesync is disabled, since: c:\Program Files\VMware\VMware Tools\VMwareToolboxCmd.exe timesync status returns Disabled. EDIT 2 Some strange new issue has cropped up. I've noticed a pattern. Originally, the event ID 50 warnings would occur at about 1230pm each day. This is interesting since our veeam backup happens at 12 midday. Since I made the changes discussed here, I now receive an event ID 51 instead of 50. The new warning says that: The time sample received from peer server.ac.uk differs from the local time by -40 seconds (Or approximately 40 seconds). This has happened two days in a row. Now I'm even more confused. Obviously the time never updates until I manually intervene. The issue seems to be related to virtualisation and veeam. Something may be occuring when veeam is backing up the PDCe. Any suggestions? UPDATE & SUMMARY msemack's excellent list of resources below (the accepted answer) provided enough information to correctly configure the time service in the domain. This should be the first port of call for any future people looking to verify their configuration. The final "40 second jump" issue I have resolved (there are no more warnings) through adjusting the VMware time sync settings as noted in the veeam knowledge base article here: http://www.veeam.com/kb1202 In any case, should any future reader use ESXi, veeam or not, the resources here are an excellent source of information on the time sync topic and msemack's answer is particularly invaluable.

• 50 Years of LEDs: An Interview with Inventor Nick Holonyak [Video]

  - by Jason Fitzpatrick

  The man who powered on the first LED half a century ago is still around to talk about it; read on to watch an interview with LED inventor Nick Holonyak. The most fascinating thing about Holonyak’s journey to the invention of the LED was that he started off trying to build a laser and ended up inventing a super efficient light source: Holonyak got his PhD in 1954. In 1957, after a year at Bell Labs and a two year stint in the Army, he joined GE’s research lab in Syracuse, New York. GE was already exploring semiconductor applications and building the forerunners of modern diodes called thyristors and rectifiers. At a GE lab in Schenectady, the scientist Robert Hall was trying to build the first diode laser. Hall, Holonyak and others noticed that semiconductors emit radiation, including visible light, when electricity flows through them. Holonyak and Hall were trying to “turn them on,” and channel, focus and multiply the light. Hall was the first to succeed. He built the world’s first semiconductor laser. Without it, there would be no CD and DVD players today. “Nobody knew how to turn the semiconductor into the laser,” Holonyak says. “We arrived at the answer before anyone else.” But Hall’s laser emitted only invisible, infrared light. Holonyak spent more time in his lab, testing, cutting and polishing his hand-made semiconducting alloys. In the fall of 1962, he got first light. “People thought that alloys were rough and turgid and lumpy,” he says. “We knew damn well what happened and that we had a very powerful way of converting electrical current directly into light. We had the ultimate lamp.” How To Get a Better Wireless Signal and Reduce Wireless Network Interference How To Troubleshoot Internet Connection Problems 7 Ways To Free Up Hard Disk Space On Windows
