How to install the Internet Defense League ‘cat signal’ on your Tumblr blog

Want to help protect the Internet from ignorant or downright dangerous politicians? Now you can, with the help of the Internet Defense League’s (IDL) newly launched “cat signal.” What the heck is a “cat signal,” you ask? Read on…

Inspired by both Batman and the Internet’s love of felines, the cat signal is a bit of code created by the IDL that anyone can embed on their website. Anytime a piece of legislation, trade agreement, or other government action that poses a threat to the open Internet rears its ugly head, the cat signal will activate, alerting legions of Web users that the time for action has arrived.

The IDL — which was founded by nonprofit Fight for the Future (FFTF) and is supported by organizations like Reddit, Mozilla, WordPress, and the Electronic Frontier Foundation (to name just a few), as well as members of Congress, including Rep. Darrell Issa (R-CA), and Senators Jerry Moran (R-KS) and Ron Wyden (D-OR) — seeks to establish a movement of Internet users that will help fight for the Web, just as 24 million of you did during the battle against the Stop Online Piracy Act (SOPA) and the PROTECT IP Act (PIPA) early this year.

If you ask me, the cat signal is a fantastic idea: having to keep up with the slew of bills that could change the Internet as we know is a full-time job, and many Web users who would otherwise help fight the good fight are already worn out by the process. With the cat signal, you’ll know when it’s really time to act. So here’s a quick guide for installing the cat signal code on your blog.

Step 1: Sign up

Before you can get the code, you’ll need to become a member of the IDL. To do this, just head over to InternetDefenseLeague.org, and sign up. You’ll either need to enter in your website and email address, or authorize the IDL Twitter app, which will both sign you up as a member and give the IDL permission to periodically send out tweets through your account. (You can choose how often it may do this.)

Step 2: Grab the code

Once you’ve signed up, you’ll have access to the code via the IDL website. Click the “Get the code for your site” link, and you’ll be given a number of options. The first choice is whether you want the “modal” cat signal, which will display a notice over top of your entire website, or simply a notification bar-style cat signal, which is less obtrusive for your site’s visitors, but also easier to ignore (and thus less effective). You can also choose whether you want your cat signal to activate every time the IDL launches a new campaign, or whether you want to manually activate it every time a new campaign goes live.

Side note: The IDL also offers a number of “badges” that you can install on your blog, which will tell people that you’re member even when the cat signal is not active. You have six different designs to choose from, some big an prominent, others small and less noticeable. I’ll be installing one of these as well, though it does not affect the functionality of the cat signal whatsoever.

Step 3: Install

For this test, I’m going to go with the full-screen modal option, and allow the IDL to activate my cat signal anytime a new campaign launches. (The instructions for installation are the same regardless of which options you choose.) I’ll also be using my personal Tumblr blog for this test, but the cat signal should work with any website.

First, select all the code that appears in the text box at the top of the page, and copy it by right-clicking on the selected text and choosing “copy.”

Next, go to Tumblr.com (log in, if necessary), and select the blog you want to install the cat signal on. Click on “Customize theme,” which appears in the top right corner. Then click the “edit HTML” button, which appears near the top, on the left side of the window.

A box showing all the CSS code of your Tumblr blog will open. Scroll down to the bottom of the page. You should see a line of script that reads “</body>”. With your mouse, set the cursor to the line just above “</body>”, and hit “enter” to make a new line. Paste the cat signal code there, and hit the “update preview” button at the top of the window. If you see the cat signal pop up, you’re good. Click save, and visit your homepage to make sure everything is in working order. If you chose the modal cat signal design, it should look something like this:

Optional step: Installling your badge

As mentioned, this part is totally optional. But while we’re here, we might as well go for it. First, go back to the IDL page where you got the cat signal code, and pick out which badge you’d like. I’m going with the “Shield Badge” option. Next, copy the code for your badge, and head back over to Tumblr. Click “Customize theme” again. Now, here’s where things may differ, depending on which badge you choose. I decided that I wanted my badge to appear beneath my bio/description on my blog (my blog is called Creeping Jesus), so rather than open the HTML editor, I simply pasted the badge code directly into the description box. You can choose to put your badge elsewhere, but you’ll have to play around with the placement of the code so your badge appears as you want it to.

Warning: If you do this, make sure to copy/paste/save your original blog code in a separate text document, so you can revert back to it if things go awry.

Now you’re all set to go forth as a hero of the Internet. Godspeed.

Take a moment and think about how often you shop at your local Walmart. Is it weekly? Daily? If either of those is the case, it might be time to upgrade your shopping experience. The Walmart Plus free trial is your chance to check out what the retail giant has to offer. Walmart Plus is basically Amazon Prime for Walmart. You get free shipping on most orders, early access to deals and new product drops (like PS5 restocks), the best grocery delivery, and more. If Walmart is your go-to option for the best smart home devices or the best tech products in general, you should get a membership. If you want to test out the service, you can sign up for a free trial. We have all the information you need right here.
Is there a Walmart Plus free trial?
There is a Walmart Plus free trial available, and it’s one of the best free trials we’ve seen in terms of how many great features and conveniences you’re able to access. This is really a reflection of how great the Walmart Plus service is, as the Walmart Plus free trial is essentially a 30-day experience of what it would be like to be a paid Walmart Plus subscriber. A Walmart Plus membership can help you save over $1,300 per year, so taking advantage of the 30-day free trial is a great way to get in there and see what those savings will look like. And if grocery delivery is what you're really after, an alternative you might consider is the Instacart free trial -- they have more than one program to try!

As part of a Walmart Plus free trial, you’ll get free shipping with no minimum order, so even small orders will qualify for free shipping. You’ll get fresh groceries and more with no delivery fees, and all at the same low in-store prices Walmart shoppers are used to. Walmart Plus members, and Walmart Plus free trial members, get exclusive access to special promotions and events, as well as a savings of up to 10 cents per gallon on fuel. A new addition to the perks of being a Walmart Plus member is free access to Paramount Plus, a top-notch streaming service with more than 40,000 TV episodes and movies. All of this is accessible for 30 days through a Walmart Plus free trial, and once those 30 days are up, Walmart Plus is just $8.17 per month or $98 annually.

Windows includes many interesting tools, but if you’re like many people, more and more of your digital life is happening in your web browser and nowhere else. That being the case, you’ll want to keep your most important websites close at hand. The easiest way to access them in Windows is the Start menu and the taskbar, treating them more or less like programs in and of themselves.

Although easy overall, getting a website from your browser to your taskbar is slightly different depending on which browser you’re using.
