WorldWide net rankings

It seems to me the U.S. is not even close to the top 10 nations in download speed, and the fastest city within the United States doesn’t even break into the top 20, worldwide . . .

Tip: 5 things you may not know you can do with attachments in Gmail

The more I use Google Docs, the less I have to deal with sending attachments back and forth. While attachments’ days may be waning, they’re still very much a part of most people’s email experience. Here are five things you may not know you can do with Gmail to make sending, receiving, viewing, and finding attachments easier:

1. Drag attachments in
Simply drag files from your desktop right into the message you’re composing and they’ll upload from there. (Make sure you’re using Google Chrome or Mozilla Firefox 3.6 for this to work.)

2. Select multiple attachments
Attaching multiple files one by one is no fun. Instead, just multi-select the files you want to attach by holding down the Ctrl key (or Command on a Mac) and clicking on each file you want to attach. Holding down the Shift key will select a continuous list of files.

3. Never forget an attachment again
Gmail looks for phrases in your email that suggest you meant to attach a file (things like “I’ve attached” or “see attachment”) and warns you if it looks like you forgot to do so. Every day, this saves tons of people the embarrassment of having to send a follow up email with the file actually attached.

4. View attachments online
When you receive an attachment, sometimes you just want to view it and there’s no need to download or save to your desktop. The Google Docs viewer allows you to view .pdf, .ppt, and .tiff files in your browser. Just click the “View” link at the bottom of the message.

5. Find that long lost attachment via search
If you’re looking for an attachment someone has sent to you, Gmail’s advanced search operators can help you find what you’re looking for quickly and accurately.

A couple examples:

  • To find all messages that contain attachments: has:attachment
  • To find all messages from your friend David that contain attachments: from:david has:attachment
  • To find all messages that have .pdf attachments: has:attachment pdf
  • To find a specific attachment named physicshomework.txt: filename:physicshomework.txt

spare resource utilization

Posted by John on 9th June 2010

Pretty interesting stuff : http://silverline.librato.com/ that’s in open beta right now.

Join our free Beta! Librato’s new Silverline service enables you to get more work done in your existing cloud or datacenter servers by letting workloads that are not time-critical run in the same servers as your primary applications, and “sponge up” the unused resources. With that, Silverline allows you to process your workload on a smaller number of servers without any impact on the Quality of Service provided by your primary applications; guaranteed!

Whether you utilize a server for 10% or 90%, it will cost the same; Silverline helps you to make the most effective use of the server resources you pay for. Sign up now for the free Silverline beta program and get special benefits when Silverline is officially launched.
Beta users will receive a 20% discount during their first year of use if they decide to use Silverline after the official launch! Sign up and start using Silverline for free today!

  • What can it do?

    Silverline restricts background workloads to safely only use spare resources not required by the primary application running on a server. For EC2 users: Silverline provides similar benefits as spot instances, but with lower cost and without interruption of service. It allows you to fully utilize your server resources by:

    • Running grid workloads along-side interactive or transactional applications
    • Completing background tasks, such as data analysis, media conversion, web crawling, or search indexing in parallel with the primary application running on a server
    • Performing backups and other maintenance tasks without impacting the primary application on a server
  • How does it work?

    Librato Silverline encapsulates background applications in a “virtual application container” that only consumes resources not used by the primary application running on a server. This allows the background application to utilize all unused resources on the server, accomplishing additional work without additional cost, and with absolutely no impact to the primary workload.

    Silverline monitors resource consumption 100 times per second, guaranteeing that “Silverlined” applications will not affect the primary application. It supports Linux and Windows running on virtual or physical servers, and requires that the primary and “Silverlined” applications run on the same Operating System. The Silverline technology is part of Librato’s Load Manager, deployed in Enterprise data centers since 2008.

  • How do I use it?

    Silverline is easily downloaded and installed on virtual or physical servers running Windows or Linux.

    After installation you can type:

    > silverline <application name>

    for any application that you want to take advantage of spare capacity on the server. This will launch the application in a background container and ensure that it only consumes resources not required by the primary application. You can be running your first Silverlined application in minutes!
