More and more it’s becoming commonplace to see a QR code – or “QR barcode” – in all sorts of places. In part that’s because there is a free app for nearly every smart phone that includes a QR code reader (most bar code scanner apps also include a QR code scanner). Also, it’s pretty easy to make a QR code; you just go to a QR code generator website, plug in your info, and voila, you have your very own QR code.
If you have ever suffered a forgotten passcode on your iPod iTouch, iPad, or iPhone, then you know how frustrating it can be when you are sure you could remember it if only you had enough tries, but your iPhone (or iPad or iTouch) has other ideas. “Forgot passcode? Bzzt..too many tries,” and then you get the dreaded “iPod iTouch is disabled try again in 1 minute” or “iPad is disabled try again in 5 minutes” or “iPhone is disabled try again in 15 minutes.” The “try again” timeout intervals increase with each wrong guess (the first 5 guesses are ‘free’, then each additional wrong guess imposes another time out penalty). Well, here is how to end run those disabled timeouts, so that you don’t have to wait, and can keep on guessing as many times as you need to until you finally remember that forgotten passcode.
Have you ever been reading a PDF file, or a website, on your Mac, and been frustrated at the lack of a “Page down” or “Page up” key? In fact, it’s very easy to page up or page down on a Mac, but it’s not obvious how to do it. Here is how to page down on a Mac (or page up on a Mac).
Android is an awesome mobile operating system – so awesome, in fact, that many report that Android sales are overtaking those of the iPhone. The Android market – where you can find and download Android applications for your Android phone, is extensive, and the majority of apps are free. It’s easy to load your phone up with apps, but at some point you will need to know how to uninstall apps on an Android phone, because you will want to delete apps from Android to make more space on your phone, or you will want to remove an application simply because you don’t use that application any more. It’s very easy to remove an Android application – in fact easier than with an iPhone. To remove an app from Android, just follow these simple steps.
With the rash of Facebook spam and viruses going around (such as the “Vote for Nicole Santos” spam, and the “Please do your part in PREVENTING SPAM by VERIFYING YOUR ACCOUNT. Click VERIFY MY ACCOUNT right next to comment below to begin the verification process…” spam), it’s important that you know how to remove something that has been posted to your wall (never click on the “Remove this app” or “==VERIFY MY ACCOUNT==” links, those are links intended to trick you into infecting your machine!) Removing a post or comment from your wall is actually very easy. Here’s how to do it:
It’s so easy to end up with a big collection of apps, isn’t it? There are so many free applications, so many interesting looking apps, that you can eat ’em like candy. But eventually they start taking up too much space on your iPhone, iPod or iTouch, or on your hard drive in iTunes. Here is how to remove an app from your device, from iTunes, and from your hard drive.
One of the least attractive qualities of the new Facebook Groups is that anyone can create a group, and then they can add anyone to the group, so suddenly you are a member of a group for which you never asked to be signed up. This is a form of spam, pure and simple, and it is evil for someone to do it to you, just as it is evil for Facebook to set it up that way. Here is how to delete yourself from that group, and also how to report it as spam for signing you up in the first place.
One of the more useful features of Paypal is that you can set up an automatic subscription payment – i.e. a regularly recurring payment – so that if you have a monthly payment to a business that is the same each month, you can set it up once and forget about it, safe in the knowledge that your automatic payment will be made on time each month. (The merchant with whom you are setting up the Paypal subscription will give you a link to create the subscription’s recurring transaction.) These Paypal recurring subscription payments are very convenient, but what about if you want to stop them? How do you cancel a Paypal subscription payment? Here’s how:
While we are talking about how to lock down the Internet access on an iPod Touch, iPhone or iPad so that you can safely let a child use it without having to worry about what they may access on the Internet, you may find yourself having forgotten the parental restrictions passcode (that allows you to reset parental controls to disable Safari, email, etc.), and wanting to reset it. If you haven’t jailbroken your iPod Touch or iPhone or iPad, then the standard advice – to do a factory reset through iTunes – may still be your best bet. But if you have jailbroken your iPhone or iPad or iPod Touch, then you can actually remove and reset the parental restrictions passcode without having to reset your device! (Oh happy days!) Here’s how you do it:
If you are a conscientious parent who wants to let their child use an iPod Touch (or “iTouch”) or iPad, but who wants the iPod Touch wifi disabled before you give it to them, you may be frustrated at the lack of any way to disable wifi so as to lock down the iPad or iPod Touch internet access. You can’t password protect the internet access on an iPod Touch or iPad, as there are no passwords for iPod iTouch wifi. In fact, natively, there is no way to disable or password protect the iPod Touch internet access (how stupid, Apple, get on the ball here! Give us some iPod Touch wifi apps to disable wifi!) Oh sure, you can put parental control restrictions on individual applications (Safari, Email), but your child can still turn the iPod Touch wireless internet on, and for some parents, that’s still too much of a risk (and we say “Bravo!” to them for ‘getting’ it). There is, however, an iPod Touch hack that will allow you to disable wifi on your iPod Touch or iPad, by password protecting the iPod Touch wifi on/off switch, and here it is.
At this point in your Internet life, it should hopefully come as no great shock that Google watches just about everything you do on the Internet, and one way that they do that is with the cookies that they’ve planted in your browser (in fact if you use both Google and Facebook, it’s a good bet that very little that you do online isn’t being tracked by one or the other, if not both). This includes a tracking cookie that Google has ‘helpfully’ given you for Google ads (that advertising by Google that is known as Adsense to website visitors and publishers, and Adwords to the advertisers who advertise in those ads by Google). based on what they perceive to be your preferences. Interestingly, Google also gives you a way to modify the information in that cookie, so that Google can show you more advertising that you ‘want’ (for some value of want).
How would you like to be able to download everything you have ever posted to Facebook – all your photos, all your videos, all your status updates – along with all the posts to your wall, and even your list of friends – all at one fell swoop, in one file, that you can store on your computer? Well now you can! Here’s how. (Amusingly, the domain from which you will download your big zip file is, wait for it, “bigzipfiles.facebook.com”.)
You can buy and download games for your click-wheel iPod through the iTunes store – but you have to find them first. Finding iPod games seems nearly impossible; you search and all that comes up is games for the iPhone and iPad, but nothing for your iPod Nano, iPod Video, or iPod Classic clickwheel iPod. That is, unless you know how and where to look in the iTunes store. Here’s what you need to do:
