Gmail Has a Daily Limit on Sending Email

gmail account disabled

Gmail imposes a limit on the attachment size (20 MB) and the overall storage space (6 GB and growing) but there’s also a daily quote on sending email.  Break the rules and Google will disable you Gmail account temporarily without any warnings.

So while sending an email message to a large group of friends using Gmail, read the following rules to avoid temporary shut-down of Gmail:

Rule 1. If you access Gmail via POP or IMAP clients (like Microsoft Outlook), you can send an email message to a maximum of 100 people at a time. Cross the limit and your account will be disabled for a day with the error "550 5.4.5 Daily sending quota exceeded."

Rule 2. If you access Gmail from the browser, you may not address an email message to more than 500 people at a time. Try adding any more recipients in the To, CC or BCC field and your Gmail account will get probably disabled for 24-72 hours. Error: "Gmail Lockdown in Secton 4"

Rule 3. Always double check email addresses of recipients before hitting the Send button in Gmail. That’s because your account will get disabled if the email message contains a large number of non-existent or broken addresses (<25 ?) that bounce back on failed delivery.

Rule 4: This is slightly unrelated but still important - Google will disable your Gmail account permanently if you don’t check your Gmail email for a period of nine months. All the stored messages will be deleted and you Gmail address (user name) may be released for others to grab it.

Elliptic Touchless UI Puts the Input Interface in Thin Air [UIs]

Source: http://feeds.gawker.com/~r/gizmodo/full/~3/228438398/elliptic-touchless-ui-puts-the-input-interface-in-thin-air

touchless_3d_nav%20GI.jpgTouchscreen interfaces are great, but all that touching, like foreplay, can be a little bit of a drag. Enter the wonder kids from Elliptic Labs, who are hard at work on implementing a touchless interface. The input method is, well, in thin air. The technology detects motion in 3D and requires no special worn-sensors for operation. By simply pointing at the screen, users can manipulate the object being displayed in all three dimensions. Details are light on how this actually functions, but what we do know is this:

Sensors are mounted around the screen that is being used, by interacting in the line-of-sight of these sensors the motion is detected and interpreted into on-screen movements. What is to stop unintentional gestures being used as input is not entirely clear, but it looks promising nonetheless. The best part? Elliptic Labs says their technology will be easily small enough to be implemented into cellphones and the like. iPod touchless, anyone? Check out the video to see it in action.

Purple Magic is Sub-$100 Linux 3G Cellphone, Not Recreational Drug [Cellphones]

Source: http://feeds.gawker.com/~r/gizmodo/full/~3/228450433/purple-magic-is-sub+100-linux-3g-cellphone-not-recreational-drug

purple-magic-2%20GI.jpgThe fellows at NXP Semiconductors and Purple Labs have teamed up to put together the Purple Magic 3G cellphone. The Linux based handset will retail below $100, and if that does not have you interested, perhaps the video calling ability, incorporated MP3 player and high-speed internet browsing will have your bargain alarms hitting overdrive.

The cellphone will seamlessly switch between 2G and 3G networks depending on availability, and the creators hope to define a new niche in the market, where functionality does not come at too steep a price. The Purple Magic handset will be showcased at the Mobile World Congress later this month, but is said not to have any of the euphoric effects of purple haze—major downer. Nevertheless, we'll be sure to try and smoke it give it a grope when we get to Barcelona. [Slashphone]

Infrared solar panels even work at night, but can't output energy

Source: http://feeds.engadget.com/~r/weblogsinc/engadget/~3/228073304/

Filed under:


Solar's had a pretty rough time breaking the ~40% efficiency level over the years, but Idaho National Laboratory researchers have apparently developed a nano-antenna array capable of collecting power not from photonic energy as is done today, but from infrared energy that could be harvested in any weather (or even at night). The cell production process is even supposed to be ridiculously cheap compared to making standard silicon photovoltaic cells, but, as always, there's a rub. The grid collects its oscillating IR energy at ten thousand billion times per second, which is proving to be a challenge to the nerds behind the tech, who are working on a way to convert that to the 50-60Hz power that the world uses. So yeah, it might be a few more years before this one pans out (if it does pan out).

Maxablaster mega-flashlight is a step away from lightsaber

Source: http://feeds.engadget.com/~r/weblogsinc/engadget/~3/228267673/

Filed under:


You thought the goggles did nothing before? Shine the 38-million-candle Maxablaster (which, we hear, has been bumped up to 52m in a recent build) and watch as faces melt Raiders of the Lost Ark style under its concentrated mercury arc plasma bulb powered by a 54 battery pack. Right now it's just the pet project of a Dutch engineer by the name of Ralf Ottow, which is probably for the best, since this would be far more effective at boring holes in concrete than lighting any scene.

[Thanks, Trev]
