‘Liquid armor’ based on shear-thickening non-Newtonian fluids

Speaking broadly, non-Newtonian fluids are of two types: Either they get thinner under shear, or they get thicker. Shear-thickening fluids, like the common corn flour-water mixture sometimes called “oobleck,” obviously, get thicker when a force is applied. This new and highly secretive non-Newtonian fluid formulation by British defense giant BAE is like oobleck to the power of ten, and can, reportedly, be very effectively combined with Kevlar to improve human body armor performance against bullets.

The Holy Grail of Ubiquitous Plain-Text Capture [Plain Text]

By Adam Pash, LifehackerJuly 12, 2010 at 12:00PM

The Holy Grail of Ubiquitous Plain-Text CaptureDespite all the cool productivity porn modern technology has birthed, the Holy Grail for me is simple: I want to create and edit plain text from anywhere (desktop/tablet/phone), and I want the results to sync flawlessly between devices. And now I can.

Ubiquitous capture—that is, the ability to snag any thought or idea any time and any where it happens to crop up—is a key component to nearly every productivity philosophy. You want to capture those fleeting ideas before they’re gone, and you don’t want to waste brain power obsessing over remembering it until you can write it down somewhere. Below, I’ll walk you through the best ubiquitous capture system I’ve ever encountered.

First, a note: What works best for me may not be what works best for you. A lot of people prefer applications like Evernote, which lets you capture nearly any form of text or media you want and is accessible via the web, desktop applications, and smartphone apps. Personally, Evernote’s a bit too large (and sometimes too bloated) for my taste. All I’ve ever wanted is the ability to create plain text files on my computer, sync those files to my phone and other computers (without any extra effort on my part), and the ability to edit or create new files from any of those buckets. That’s what I describe below.

The Glue: Simplenote

The Holy Grail of Ubiquitous Plain-Text CaptureWe’ve mentioned Simplenote once before on Lifehacker, but just to recap: Simplenote is a killer web application that does one very simple thing very, very well. That one thing? Creating, editing, and managing as many plain text notes as your heart could ever desire. Apart from managing my to-do list, my ideas list, my shopping list, and virtually every other list I could ever need, I now write nearly everything in Simplenote (including the post you’re reading right now). Simplenote has a really good, open API, so you can also find desktop applications and smartphone apps that work with Simplenote—which I’ll get to in a bit. First, here’s a look at Simplenote’s web interface:

The Holy Grail of Ubiquitous Plain-Text Capture
(Click any of the images for a closer look.)

Simplenote may seem a touch peculiar at first, so here’s a rundown of how it works:

The Holy Grail of Ubiquitous Plain-Text Capture

  1. This is the search box. When you want to find a note—either by title or by text inside that note—just head to the search box. Every application that plugs into the Simplenote API generally works similarly.
  2. These are your notes. Enter a search, and Simplenote filters out and narrows down the matches. Click on a note or navigate through the list with the up/down arrows to open it.
  3. This is the main content area. It displays your current note. Pretty obvious, right?
  4. Click this + (plus) button to create a new note. The first line of your new note will become your note’s title.

This is all pretty simple so far, right? And well it should be. The whole point here is that it’s a lightweight, no-nonsense tool for managing your lists and notes. The web version of Simplenote highlighted above is nice because it’s accessible to any browser (just log in to get to your notes), but that’s still not perfect. What we really want is to be able to access our notes offline from our phone or desktop and sync back to Simplenote when necessary. So let’s figure that out.

Simplenote on Your Desktop

The Holy Grail of Ubiquitous Plain-Text Capture
Simplenote comes in a variety of flavors for desktop users, but the two best apps I’ve found are ResophNotes (for Windows), pictured above, and Notational Velocity (for OS X), pictured below. Both closely mimic the functionality of the webapp, so my explanation of the webapp above applies to these desktop applications, as well. With both apps, just open the preferences and enter in your Simplenote credentials to get them up and syncing. (If you haven’t already registered for a Simplenote account, you can do so here.)

The Holy Grail of Ubiquitous Plain-Text Capture

The nice thing about the desktop applications is that you can create and edit new notes even when you’re offline, and they’ll take care of syncing the results back to Simplenote when you’re back online. Both Notational Velocity and ResophNotes are very keyboard-friendly, too, which goes a long way toward winning over the keyboard shortcut lovers at Lifehacker.

Notational Velocity is probably the nicer of the two if we’re comparing, namely because the app can store files in plain text in any folder—meaning I can easily back up my notes to my Dropbox folder (I’m in plain text geek heaven). ResophNotes has its charm, too, including a few features—like a one-click force sync—that we’d like to see in Notational Velocity. Either way, both apps are excellent in the same way Simplenote is. They’re barebones, distraction-free, plain text editors that help you focus on text and text only. If you’re going to use Simplenote, I highly recommend you use a desktop application like one of these for offline access and backup. You can check out all of the various Simplenote desktop apps and browser extensions here.

Note: Now is probably also a good time to mention that a couple of us at Lifehacker are currently working on a cross-platform, open-source Adobe AIR app for Simplenote called Textify with hopes of bringing the best features we can come up with to every platform. We’re still in the very early stages of development, but you can find the latest source here on GitHub. We’re happy to accept help!

Of course, the Holy Grail of plain text syncing and editing isn’t really complete until you can do it all from your phone.

Simplenote on the iPhone and iPad

The Holy Grail of Ubiquitous Plain-Text CaptureThis is where iOS users really win out. Simplenote is available (from the folks who built the webapp) as an iPhone and iPad application. It’s fast, snappy, and, frankly, better than their web version. Each time you open it, it syncs with all your latest notes if you’ve got a connection; if you don’t have a wireless connection, you can still edit your notes and let Simplenote sync your changes back to Simplenote on the web next time you do. You can see Simplenote running on the iPhone in the screenshot to the left and running on the iPad in the screenshot below.

The Holy Grail of Ubiquitous Plain-Text Capture
Coupled with a bluetooth keyboard, the iPad version of Simplenote is a real gem. I now do the majority of my long-form writing on my iPad, which is propped onto a $1 business card iPad stand. With everything set up, I feel like I’m writing on a distraction-free typewriter—one that just happens to be connected to the internet and that syncs flawlessly to my desktop, the web, and my phone. Simplenote for iOS also supports TextExpander touch for quick text replacement snippets.

The Holy Grail of Ubiquitous Plain-Text Capture

But what about Android/my other non-iPhone? Good question. Since Simplenote is web-accessible, you certainly can fire up the web interface and add some notes from there, but the web interface is not really mobile-friendly. Some people have been working on an open-source version of Simplenote for Android, but it’s still not quite there yet. We’ll keep our eyes on it, though, and let you know if it ever makes it to primetime. Likewise, we haven’t seen any apps for other devices that plug into Simplenote’s API, but hopefully a little exposure will inspire some like-minded developers.


Simplenote certainly isn’t the only solution that can accomplish the same (or at least similar) results, but it is the best solution I’ve found to fit my needs. If you’ve got a different method you prefer, tell us all about it in the comments.

Nesco Food Dehydrator

By (author unknown), Cool ToolsJuly 09, 2010 at 01:28PM

The Nesco Food Dehydrator is a simple, affordable, and well-built tool for drying foods quickly and thoroughly. Though not an every day use item for most people, when it is needed it becomes absolutely essential.

I recently went on a weekend trip hunting for morels with some friends and came back with far more than I could eat. Luckily, this dehydrator made short work of the excess. The stackable trays easily fit 60 whole small morels and many of the larger ones that had been cut in half. I fit about 2-3 pounds of mushrooms in 5 trays.
Nesco FD-75PR 700-Watt Food Dehydrator-2.jpeg

Like the previously reviewed Excalibur Food Dehydrator, the Nesco model has a temperature control, fan, and heating unit. The Nesco’s heating unit is built into the top (other cheaper models heat from the bottom up) that sits on top of the stack of trays and blows air through a central column allowing for better distribution and airflow throughout. I used a temperature of 110 ˚F (or 43˚C) when drying morels, and left them to dry over night (about 8 hours). They were perfectly dried the next morning, and ready for storage in an airtight container. Any moisture left in mushrooms will lead to a ruined batch so I made sure to let them dry out for a little longer than necessary.
Nesco FD-75PR 700-Watt Food Dehydrator-1.jpeg

While I have mainly used this model for drying mushrooms, the large trays and variable temperature dial (95-160 ˚F) allows for a wide range of dried foods to be made. This particular model is also expandable to 12 trays if you need to dry a truly astonishing amount of food.

The Nesco, when compared with the Excalibur, has the benefit of being nearly $125 dollars cheaper combined with a smaller expandable footprint, a relatively quiet fan, and similarly adjustable temperature.

How To Get Your Very Own Free SSL Certificate

By Mohan Ramkumar, MakeUseOfJuly 07, 2010 at 02:31PM

free ssl certificatesA Secure Sockets Layer (SSL) certificate helps us to encrypt the data being transmitted via the Internet. It will come in handy if you are running a blog or a personal webpage and logging into them from an unsecured public access WiFi Hotspot (such as coffee shops, airports etc).

Transmission of your login information over an unsecured connection can be intercepted and hacked. Internet security is a topic of interest for MUO authors and our readers alike.

SSL certificates encrypt the login data before transmitting them to your ISP/server making it harder for eavesdroppers to break in. That’s exactly why banks, financial institutions, ecommerce sites etc. use SSL for securing login information, user identity information and credit card data.


SSL certificates cost a lot if bought from providers like Verisign, GoDaddy etc. For those us who don’t run mission critical portals, that is not an option. Let us see how to get free SSL certificates from StartSSL.

Obtaining The Free SSL Certificate

A simple signup form kickstarts the process of getting the free SSL certificate. All the details, including home/company address to phone number are mandatory requirements. Once the signup is done, an email with the verification code is sent to the email address you specified.

free ssl

After entering the verification code, the application is sent to the second stage of verification by the StartSSL team and we are advised to wait for about six hours before being contacted by their team.

However, I got a confirmation mail in less than 5 minutes with a link to the account. Remember, this email is good for only 24 hours from the time it has been received, so act fast.

Installing The SSL Certificate

StartSSL offers free certificates with no holds barred and with absolutely no hidden charges. You can choose either a 128 bit or 256 bit key for encryption.

free ssl certificates

We have the option to choose between a high grade or medium grade private key. Once the type of key is selected, it is generated and we are taken to the installation page.

Once the install button is clicked, the certificate is installed. There is also an option to download and store the certificate to an external disk and I strongly advise you to do it.

Now that the certificate is installed in the browser, we can just click on the Authenticate option to enter the control panel. No need for an username and password. We are identified by way of the unique private key and hence it is very important to back it up securely.

Validating The Domain Name

After authentication, we can start the process of validating the domain name & the email address with the help of the Validations Wizard. From the dropdown, you can choose the appropriate option. Let us go ahead and validate a domain name.

Once we enter the domain name, an email address has to be associated with it to confirm domain ownership.

free ssl cert

Once the email address is verified, the domain is validated. However, this being a free SSL certificate, StartSSL requires the renewal of this validation every 30 days, which involves the same process.

free ssl cert

Certificate Wizard

I chose the Webserver certificate since I am planning to use it for my WordPress installation. We need to enter a password to create a private key and then we have to enter the subdomain where the certificate will be used. Subdomain is a mandatory requirement.

The certificate created will support the domain and the sub domain. As the final step, we now have the text box displaying the encoded certificate information. Copy the content, paste it in a notepad file and rename the file as ssl.crt

The same page also has links to download the intermediate and root certificates. Download them to the same folder.

Uploading Files To Server

Navigate to the How to Install section in the FAQ section. Choose your server setup, for example Apache and you will have the code to modify the http.conf or ssl.conf file. Copy it and update the file in the root folder of the domain in your webserver.

From the same page download the ca.pem & sub.class1.server.ca.pem files. Upload all the files to the root folder and now we have the SSL enabled connection at the website.

free ssl certificates

Final Thoughts

Please exercise caution with the last step and ensure that all the directories (marked by arrows in the image above) follow the same naming convention of your ISP or location in your webserver. And do remember to validate the domain every 30 days to enjoy the security provided by the free SSL certificate.

Are there any other services offering free SSL certificates? If you know of any, do share them with us.

Federal Circuit Extends the Scope of 102(e) “Secret Prior Art”

By Dennis Crouch, Patent Law Blog (Patently-O)July 07, 2010 at 02:08PM

In an important case, the Federal Circuit has expanded the scope of so-called 102(e) “secret prior art.” Under the decision, a US patent or published application will be considered prior art as of the filing date of its qualifying provisional application.  The case is important because of the large number of provisional patent applications being filed each year.

* * * * *

In re Giacomini (Fed. Cir. 2010)

Giacomini’s patent application was filed on November 29, 2000.  In his search, the examiner found U.S. patent 7,039,683 (the “Tran patent”) and asserted that patent as prior art over Giacomini.  The Tran patent application was filed in December 2000 (after Giacomini) and issued in 2006. However, the USPTO asserted that the patent should be considered 102(e) prior art because it claims priority to a U.S. provisional application that was filed in September 2000.

35 U.S.C. 102(e)(2) bars patentability if

the invention was described in . . . a patent granted on an application for patent by another filed in the United States before the invention by the applicant for patent, except that an international application filed . . . shall have the effects for the purposes of this subsection of an application filed in the United States only if the international application designated the United States and was published under Article 21(2) of [the PCT] in the English language.

The question in this case is whether the 102(e) priority date for prior art reaches-back to the filing date of the provisional application. On appeal, the Federal Circuit agreed with the USPTO that the provisional filing date is the 102(e) priority date.

In the 1968 case of In re Klesper, the Federal Circuit predecessor court (the CCPA) held that the 102(e) follows the prior precedent of treating a prior art disclosure found in an issued patent as being disclosed as of the “filing date of the earliest U.S. application to which the patent is entitled, provided the disclosure was contained in substance in the said earliest application.”  The Federal Circuit agreed that this provision applies equally to provisional patent applications “ so long as the provisional application [provides] written description support for the claimed invention . . . in accordance with Section 119(e).”  Giacomini never argued that the provisional failed to describe the invention found in the prior art.

Therefore, the Tran patent “shall have the same effect,” [Citing 119(e)] including a patent-defeating effect, as to the claimed invention as though it was filed on the date of the Tran provisional. Accordingly, Giacomini, who filed his application after Tran filed his provisional application, cannot receive a patent covering the same subject matter under 35 U.S.C. § 102(e).

This decision follows the BPAI’s 2008 precedential of Ex parte Yamaguchi, 61 U.S.P.Q.2d 1043 (BPAI 2008). However, the decision is in tension with the Hilmer doctrine. In re Hilmer, 359 F.2d 859 (CCPA 1966) (a U.S. application’s 102(e) priority date does not extend to its Section 119 foreign filing date). Giacomini had argued that provisional applications should be treated like foreign filings rather than like non-provisionals because the priority statute for provisional applications is also found in Section 119 and becaues provisional applications lack the formality of non-provisionals. 

Note: US Court interpretations of 103(a)/102(e) offer a major difference between US practice and European practice. Namely, in the US secret 102(e) prior art is available to be combined as part of an argument for obviousness while in most European countries, the filing date of prior art is only important for novelty purposes.
