Maak een backup van je google sites

Google heeft een prachtige manier om websites te maken. Gekoppeld aan jouw account zijn ze eenvoudig te beheren en te ontsluiten.

Je kunt deze sites ook in plain HTML op je eigen schijf backuppen. Daarvoor heeft de groep onder de naam Google sites liberation een java tool ontwikkeld die het bijzonder eenvodig maakt om een HTML backup van een site te maken  en wat nog mooier is deze weer terug te plaatsen:

Helium is gevaarlijk

Ballonnen zijn een onmisbaar bestanddeel van feestjes. Nu is aan een ballon met gewone lucht niet zoveel plezier te beleven, want zo’n ballon stijgt niet op. En dus worden ballonnen bij voorkeur met helium gevuld.
Op 14 november 2008 is er in Ierland een 13-jarig meisje aan het inademen van Helium overleden. Het meisje werd door haar moeder dood gevonden in haar kamertje. Ze was pas jarig geweest en had van haar verjaardag nog wat ballonnen over, die met helium waren gevuld.Waarschijnlijk heeft ze het gas ingeademd om daarmee een piepstemmetje te krijgen – iets wat op feestjes regelmatig door kinderen en door volwassenen wordt gedaan. Als je zuiver helium inademt, krijg je namelijk een Donald Duck-stem, doordat de snelheid van het geluid in helium veel groter is dan in lucht. Het gevaar van het inademen van helium is verstikking. Dit gevaar wordt vaak gebagatelliseerd. Het effect van het inademen van helium wordt vergeleken met het inhouden van je adem - en zo erg is dat toch niet? Door het inhouden van je adem kun je echter niet stikken. Zodra CO2 opbouwt in je bloed, neemt je ademreflex automatisch de leiding over en word je gedwongen, adem te halen. In tegenstelling tot wat men denkt, kijkt ons ademhalingsstelsel namelijk niet naar het zuurstofgehalte in het bloed om de ademhaling te reguleren, maar naar de ophoping van CO2. Wanneer je een gas inademt dat geen zuurstof of CO2 bevat, loopt het CO2-gehalte in het
bloed niet op. Daardoor merken de hersenen niet dat er geen zuurstof is – en volgt er dus ook geen ademreflex.
Je raakt gewoon bewusteloos en als je pech hebt, sterf je. Zo simpel en snel kan dat gaan. Een gezonde persoon die één ademteug neemt van een heliumballon, komt hier meestal zonder schade van weg.
Maar de neiging is, een diepe teug te nemen om het effect op de stem te versterken. Na de eerste teug blijft dan helium achter in de longen. Een tweede teug kan genoeg zijn om alsnog te stikken. Bij iemand van wie hart of longen niet in goede conditie zijn, kan de eerste teug genoeg zijn. Of men heeft gewoon pech. Bij verstikking zijn de eerste tekenen vaak lichtheid in het hoofd of een verminderd bewustzijn. Bij een inert gas hoeven zulke fysieke signalen niet op te treden.
Nu denk je misschien: dit was maar 1 dode – dit komt toch nooit voor? Fout. Enkele jaren geleden waren twee studenten in Florida zo handig, om een grote reclameballon naar beneden te trekken en er samen in te kruipen. Een eenmalige actie. Ze werden gevonden door de buurman die hun benen uit de ballon zag steken - dood. In januari 2008 stierf een Amerikaanse puber toen hij high probeerde te worden door helium te blazen in een plastic zak die hij over zijn hoofd had gebonden (“huffing”). Zijn ouders vonden hem de volgende morgen. Of de jongen die direct uit een heliumcilinder ademde. Die stikte niet alleen maar blies ook zijn longen op. En dan hebben we het niet over die ontelbare gevallen waarbij men wel flauw viel maar het overleefde. Op youtube staan hier angstwekkend veel voorbeelden van.
Jammer. Maar u weet het nu. Mocht u ooit bij gelegenheden komen waarbij helium wordt gebruikt en men de neiging heeft om ermee te spelen: zegt het voort! Niet mee spelen dus.

Download your google data

Google has a tremendous number of free services they offer which many of your probably take advantage of. But have you ever considered what you might lose if all of a sudden you lost access to your account? Just like all important data on your hard drive, your critical data in “the cloud” should also have backup consideration.
So if your Google account contains data you can’t afford to lose or you simply would like to have a local copy of it for yourself, you can easily download just about everything.

Backup All Your Gmail Messages

Gmail offers the ability to download all your messages into a POP client. As you may know, a POP client downloads and stores local copies of emails to your hard disk so you can access them off-line or if you delete a message (which you have previously downloaded) from your Gmail account.
Once logged into Gmail, in the upper right corner click the gear icon and go to Mail Settings.
image
Under the Forwarding and POP/IMAP tab, select the option to Enable POP for all mail. Selecting this option will flag every email in your account to be downloaded to your POP client. Also be sure to select the option to keep Gmail’s copy in the inbox in step 2 so that when your messages are downloaded, they are not removed from your Gmail inbox.
Once you have set these options, save your changes.
image
Once POP access has been enabled on your account, you simply need to download the messages into your POP client. Google provides detailed instructions for several common email clients via the link in step 3. Rather than re-inventing the wheel in this article, check out their walkthroughs.

Backup All Your Gmail Contacts

After using Gmail for a while you will, no doubt, have many email contacts that you will want to backup as well.
On the left side menu, click the Contacts link. You can optionally select the contacts you want to export (if you are only exporting certain ones) or leave individual contacts unchecked and export groups.
Under the More actions menu, select the Export option.
image
Select the contacts you want to export (typically All contacts) and then the format. If you are unsure, select a CSV format because this will be readable in Excel or Notepad and just about every email client supports importing via a CSV file.
Once you have your options set, click Export.
image
Save the resulting file.
image

Download Your Google Plus Data

If you have a Google Plus account, you can easily download just about everything you have made available on the service.
Once logged into your Google Plus account, click on the gear icon in the upper left corning and select Google+ settings.
image
Select the Data liberation option on the right side menu and click Download your data.
image
The data included in the download is as follows:
  • +1′s = Web pages you have +1′d (which show in the +1 tab of your Google profile) in HTML format. This does not include every post or comment you have +1′d in the Google+ system.
  • Buzz = Google Buzz posts and replies in HTML format.
  • Contacts and Circles = Contact information by circle/group in VCF format.
  • Picasa Web Albums = Pictures uploaded to Picasa. These are organized in folders with the respective album name.
  • Profile = JSON file which contains the information in your Google profile. Don’t worry if you don’t know what this type of file is, you can open it and Notepad and read all the information.
  • Stream = Posts you have made in Google+ in HTML format. This does not include comments to posts you have replied to, only “top level” posts you have made.
You can download everything (as we do in this guide) or individual pieces. To download everything, click the Create Archive button.
image
Depending on the amount of data you have, this can take a while but once finished you will be presented with a Download button.
image
Once your download is ready, save it to your hard disk.
image
When you open the resulting zip file, you can see the data is organized into folders making it easy to navigate.
image

Download Your Google Calendars

If you utilize Google Calendars, you can easily export this information into ICAL format.
Once in your Google Calendar, click the gear icon in the upper left corner and select Calendar settings.
image
Under the Calendars tab, click the Export calendars link.
image
Save the resulting file to your hard drive.
image
When you open the downloaded zip file, you will have an ICAL file for each Google Calendar.
image

Download Your Google Reader Subscriptions

To download your Google reader subscriptions (note this downloads the source RSS feed links, not the content), click the gear icon in the upper left corner and select Reader settings.
image
Under the Import/Export tab, select the option to Export your subscriptions as an OPML file. This is simply a type of XML formatted file that you can open in Notepad to view the contents of.
image
Save the file to your hard drive.
image

Downloading Your Google Docs

If you make use of Google Docs, you can easily download selected or all documents at once. If you want only certain documents, pick the ones you want.
Once ready, under the Actions menu, select Download.
image
You will have some options with the format you want to download certain documents types in. For the most part the default settings will do but you can customize to fit your needs. Click the Download button once you are ready.
image
Save the resulting zip file to your hard drive.
image
When you open the zip file, the documents are in the format and folder structure used in Google Docs.

Evernote

Er zijn applicaties waar je nooit afscheid van zult nemen en bij mij is dat Evernote. Evernote is een dienst waar je online een aantal notebooks kunt aanmaken en daar informatie in kunt verzamelen. En met informatie bedoelen we weblinks, artikelen, foto’s, gesproken notities etc,etc. Naast de apps voor de smartphones en de iPad is er nu ook een applicatie voor de Honeycomb tablets.

Evernote voor Honeycomb

De Honeycomb editie maakt prachtig gebruik van het 10 inch scherm. De applicatie heeft als startpagina een overzicht van alle gemaakte notities, welke op maand worden weergegeven. Een klik op een notitie laat je de informatie bekijken maar aan de rechterzijkant is nog steeds een scrollbalk waarmee je naar andere notities kunt navigeren.
Het menu aan de rechterzijde is verder verdeeld in een button waarmee je naar de verschillende notitieboeken gaat of naar de verschillende tags die je aan een post kunt geven. Als laatste is er ook een pagina waar je de gedeelde notitieboeken ziet (ook dat kan).
Het maken van een notitie vergt ook maar een klik en je kunt aan de slag. Schrijven, of een artikel of foto importeren maar ook een stemnotitie. Een klik op het microfoontje laat de opname starten en je kunt tijdens het opnemen ook nog notities maken.

Evernote is een must

Het maken van de notities of bookmarks zijn helemaal simpel als je de plugin gebruikt voor de Chrome Browser. Met 1 druk op de knop kun je de info opslaan en s’avonds op je tablet teruglezen. Bij mij neemt Evernote eigenlijk ook de functie van app als Read it later over.
Omdat de dienst zowel op mijn tablet, desktop als mijn Android telefoon draait heb ik overal de beschikking over mijn gegevens en notities. Een must have !

Vliegtuigen en treinen

Zien welke vliegtuigen vliegen boven Europa en de wereld. Kijk welke treinen op tijd rijden en waar ze rijden. Heerlijk nurdig, maar o zo leuk:

Het kan oa op Frontier Casper (gratis met 15min vertraging), en op RadarVirtueel. Bij die laatste kun je bv ook een vluchtnr ingeven, zodat je bv je familielid kunt volgen :-): klik daarvoor rechts in beeld op het tabblad 'filter'. Ook op FlightRadar24 kun je Europees vliegverkeer volgen. Leuk is ook VliegtuigOnline, omdat je daar ook kunt kiezen om mee te luisteren met de verkeerstoren. Of download de Google Earth KMZ van vliegtuigvolger.nl om in Google Earth vluchten te bekijken.

Verder zijn interessante sites:

http://www.airliners.nl/Schiphol/liveradar.htm
http://www.bezoekbas.nl/ 

En voor US-based flights kun je bv FlightAware proberen, of FlightStats.

Als je een Android gebaseerd telefoon of device hebt, kun je PlaneFinder proberen.

Treinen kun je niet real-time zien rijden, maar op 'mailspool' kun je 'bij benadering' (ik kon nergens vinden op welke data het gebaseerd is, vermoedelijk de reis- en vertragingstijden van de NS-site) de treinen zien rijden, en op dit kaartje van Traphic kun je een station aanklikken en zie je de vertrekkende treinen en eventuele vertraging en wijzigingen.

Ben je geinteresseerd in varend verkeer: boten/schepen, waar ze zich bevinden, waar ze heen gaan, hun vracht etc vind je op MarineTraffic.

 Taxi's volgen? Kan (deels) ook in sommige steden.

Facebooks privacy

facebook-logoFacebook schendt privacy en in deze blog geef ik aan hoe je je hiertegenb kunt proberen te beschermen. De beste methode is natuurlijk gewoon GEEN facebook account te nemen, maar ja, Remy leeft alleen op de wereld.

1. Gebruik HTTPS

Door HTTPS i.p.v. HTTP te gebruiken is het internetverkeer beveiligd tussen jouw PC en de server. Dit wordt beveiligd met een certificaat. In firefox kun je nagaan welk bedrijf dat certificaat heeft uitgegeven.
https-firefox
In facebook kun je https aanzetten in “Account ; Account Settings“.
facebook-account-settings
Selecteer Account Security onder de Settings tab en vink de regel naast Browse Facebook on a secure connection (https) whenever possible
facebook-secure-browsing

2. Gebruik Facebook two- step authentication (Login Approvals)

Net zoals Google, heeft ook Facebook een two-step authentication service gemaakt die luistert naar de naam Login Approvals. Deze servicebiedt de gelegenheid om naast een wachtwoord ook een code naar jouw mobiel te SMSen. Pas na invoering van de geSMSte code kun je inloggen.
facebook-login-approvals

3. Controleer op Facebook email phishing aanvallen en nepverzoeken.

THIS is still to be edited

While you are in Facebook, you should never click on suspicious links even if the messages were sent from your friends. Most Facebook scams spread by posting messages to walls of all friends of the infected user. The best place to get updated news about Facebook scams is Facecrooks.com. This site will give you details about all the recent scams and other threats spreading on Facebook. Visit Facecrooks.com frequently to find out more about Facebook threats.
You should also take extra care when reading a message from Facebook. Always double-check the email address of the sender before taking any action or clicking on any link in the email. All the emails sent from Facebook will originate from facebookmail.com domain. Emails from any other domain claiming to be from Facebook will be scam and not legitimate.
facebook-mail

4. Enable login notifications

Enabling login notifications in Facebook will notify you when someone logs in from a suspicious location or computer. This is important if you always use your Facebook from the same computer and same Internet connection, Facebook will know your location and will trust the computer you’re working on. If you or someone else logs in from another location, you’ll get a notification from Facebook about the suspicious account activity.
To enable login notification, go to “Account -> Account Settings“.
Under settings tab expand “Account security -> Login notification“, check the following two boxes:
  • Send me an email
  • Send me a text message
facebook-login-notifications
You should also check Facebook Login history regularly and see if any suspicious person has logged into your Facebook account. Facebook history will tell you the recent IP addresses and devices used to login to your Facebook account.

5. Use Facebook one-time password service on public computers

Like Hotmail, Facebook also provides the facility of one-time password. One-time password is a temporary password which can only be used once and expires within 20 minutes of creation. To enable this service, you’ll need to activate a phone number so that Facebook can send messages to your mobile. To register and activate a phone number you can go to “Account -> Account settings”.
Under Mobile tab, you can activate your phone to use Facebook one-time password service. The temporary password will be sent to your mobile and you’ll be able to login to Facebook once using that password.
facebook-activate-phone

6. Check Allowed Applications Frequently

You should always keep an eye on which application you have allowed and what that application is doing. You should never install an app that looks suspicious. Always search the Internet for its reviews and install the app only if it has good rating.
I hope following all these points will give you a better and secure experience with Facebook. Last of all I would like you to attempt a security quiz from Facebook. In this quiz you’ll be asked questions about security and you can see how informed you are regarding Facebook security. You may also take a look at managing Facebook privacy options.

Create your own Ebook

With the growing popularity of ebook readers like the Kindle and iPad, more and more people are reading on a screen rather than from printed books. And more and more authors are getting into the act. Why not you?
Maybe you’re a budding author who wants to self publish. Or maybe you’re a software developer who wants to distribute documentation in a slightly different way. You could be a blogger who wants to collect a bunch of their best posts into an ebook.
There are several ways to do that. You could fire up your favorite word processor, start typing, and then create a PDF file. Or you could go straight to a format that just about every electronic device can handle. The easiest way to do that is to write an publish using Sigil

Sigil is an Open Source WYSIWYG ebook editor that produces ebooks in the popular epub format. You can read books in epub format using just about any dedicated ebook reader, on most smartphones and tablets, and even on desktop or laptop computers.
Let’s take a look at how to use Sigil to write and publish an ebook.

Installing the Software

Sigil can run on Linux, Mac OS, and Windows. You can download installers for each operating system from Sigil project’s website. If you’re in the mood to embrace your inner geek, you can also download the source code.
Once you’ve downloaded the installer, just run it. Sigil installs on your computer, and adds an icon to your Start or application menu. For example, you can launch Sigil under Ubuntu by selecting Applications -> Sigil -> Sigil.
Main Sigil window

Time to Get Writing

Sigil is WYSIWYG, which means working in it is a lot like working in a word processor. To get going, just start typing.
The main difference between Sigil and a word processor is that you don’t get all that much formatting. You can add:
  • Headings
  • Bold, italics, underline, and strikethrough
  • Bullets and numbers
  • Images
You can also justify and indent text. All of that is literally a click away on the toolbar. To apply formatting, just highlight the text and click one of the buttons on the toolbar.
Writing the ebook
Chances are that you’ll have more than just a bit of text. And chances are that you’ll want to break that text up into chapters. To do that, click to the left of the heading that you want to make a chapter title and the select Insert -> Chapter Break.
You’ll notice that something interesting happens in the left portion of the Sigil window. The new chapter is added to the Book Browser.
Book Browser
The Book Browser lists the chapters in your ebook. Out of the box, the chapters are named Section000x.xhtml, where x is a number starting at 1. You can change the name of the chapters by right clicking on them, selecting Rename from the menu that appears, and then typing a new name for the chapter.
You can also click and drag chapters in the Book Browser to rearrange them.
Once you’re finished, save the book. You can open the epub file whenever you want to edit it.

What If I Already Have Content?

A book in epub format is essentially a collection of XHTML files. So if you have content that’s already written in HTML or XHTML format, you can copy and paste that content into Sigil. To do that, open the HTML file in a text editor and copy it. Then, in Sigil, select View -> Code View.
Code view
Paste your HTML code into editing window then select View -> Book View to return to WYSIWYG mode. You’ll probably have to add chapter breaks, which was explained a few paragraphs ago.

Viewing Your ebook

Once you’ve got a draft completed, you’ll probably want to see what the product looks like. Obviously, the best way to do that is to view the epub on as many ebook readers (and other devices) as you can. Unfortunately, that’s not always possible. The next best thing to do is use the Calibre ebook management software.
After downloading and installing Calibre, use it to open your epub file. Then, click View on the Calibre toolbar. In the viewer window that opens, you can navigate through your ebook, change the size of the fonts, and see any formatting problems.
Viewing an ebook in Calibre

Conclusion

If you need a quick and easy way to write and publish an ebook, then you should give Sigil a look. It can actually do a bit more than what was described in this article, and once you get the hang of the software you’ll be able to create some very nice looking ebooks.

The Always Up-to-Date Guide to Managing Your Facebook Privacy

The Always Up-to-Date Guide to Managing Your Facebook PrivacyKeeping your Facebook info private is getting harder and harder all the time—mostly because Facebook keeps trying to make it public. To help you out, we've created a comprehensive guide to keeping your Facebook locked down and in your control, and we're going to keep it updated whenever Facebook decides to add a new feature or change its privacy defaults... yet again.
Despite plenty of user complaints, Facebook still hasn't caught on to the "opt-in" philosophy: Most of us feel that when a service adds a new feature that affects our privacy, it should ask whether we want to enable it rather than quietly enabling it for us. Facebook adds new features to their site all the time, and many of those features share information you might not want out there. Instead of regularly scouring your Facebook settings for secret new features, we're going to constantly update this guide with all the information you need about Facebook's newest privacy-related changes, including details for how to tweak your privacy settings to keep your information safe.
First, we'll walk through the basic privacy settings that determine what you share, then look at a few lesser-known settings you'll want to tweak, and finish with a few third-party tools that will help keep your Facebook information private.

The Basic Privacy Settings: What You Share

Facebook's main Privacy Settings page has a pretty good overview of what you'll want to change, and presents it in a way that's mostly easy to understand. Here's how each of the four sections work.

Connecting on Facebook

The Always Up-to-Date Guide to Managing Your Facebook PrivacyThe first section of Facebook's Privacy page is the "directory". From here, you can control who can find you on Facebook and how. Click on the "View Settings" link under "Connecting on Facebook" to access those settings. You can make each category viewable by one of five different groups: everyone on Facebook, friends of your friends and anyone in your networks, just your friends and anyone in your networks, friends of your friends only, and just your friends.
If you don't want everyone seeing all your information (like where you live or where you work), you should change them here. I let anyone search for me, send me friend requests, and see my friend list, but other than that I've left everything else as "Friends of Friends". Chances are high that if someone's friending me on Facebook, I know them through someone else, so it shouldn't be hard for them to find me—everyone else I'd rather keep in the dark about who I am, where I live, and where I work.

Sharing on Facebook

The Always Up-to-Date Guide to Managing Your Facebook PrivacyThis is the biggest section, which determines who can see your status updates, photos, contact information, and more. It's pretty easy to adjust from the main Privacy page. You can set it all to "Everyone", "Friends of Friends", "Friends Only", or customize your own settings. The table will provide a pretty easy-to-read overview of what your current settings are. This part's mostly up to you, though I've kept most of this stuff to "Friends Only".
You can click on the "Customize Settings" link below the table to further refine your choices. That lets you set each specific option to viewable by everyone, friends of friends, friends and your networks, Friends only, and so on. You can even set specific phone numbers of email addresses separately, which is pretty nice. In addition, you can also create custom friend lists (say, "work buddies") that you can include or exclude from certain information.. I'd comb through this section no matter what you do, since there are some settings here that aren't on the main table. We'll talk more about those in the next section, "Lesser-Known Settings".

Applications and Websites

This is where you'll control which Facebook applications can access your profile, and what web sites outside of Facebook can access your account. Click on the Edit settings button to tweak them.
The Always Up-to-Date Guide to Managing Your Facebook PrivacyFrankly, I think Facebook applications are awful. With the exception of certain apps (like Twitter, the iPhoto Uploader, or other legit programs I use), I try and keep this clean. Facebook applications, on the whole, are insecure, spammy, and just downright annoying. Next to the list of "Apps You Use", hit the "Edit Settings" button to see the full list. From there, you can remove an app by clicking the "X", or you can hit "Edit Settings" next to an app to see what information of yours it can access and what it can do. I usually draw the line at an application posting on my wall, unless it's something I want to post to my wall (like Twitter). Again, this will vary from person to person.
The rest of this page you'll probably want to lock down as much as possible. Under "Info accessible thorugh your friends", you'll want to uncheck all those boxes, so your friends' apps can't access your information (God knows what spammy applications they're using). You'll want to disable the Instant personalization feature as well, which will let sites like Pandora and Yelp use your Facebook account to give you extra "features" (also known as: spam). Lastly, unless you want your Facebook page coming up in Google results, you'll want to turn off Public search as well.

Block Lists

The Always Up-to-Date Guide to Managing Your Facebook PrivacyYou may think the block lists are only for ex-significant others, but there are actually some good features in there. For example, not only can you block users, but you can block app invites or event invites from specific users. So, if you have a friend that you like, but they're one of those people that invites every ding-dong Facebook user to their event (you know, even if they don't live in the same state), you can block event invites from them. Similarly, if you have friends that play way too many games on Facebook, you can stop them from inviting you.
To tweak these settings, just hit "Edit Your Lists" under Block Lists. To add a friend to any of those lists, just type in their name. You can also block them from the main Facebook interface. You can block a user that wrote on your wall, ignore event invites when someone invites you to an event, or block an app that someone invites you to. So you don't always have to come back to this page to block someone.

Lesser-Known Settings You'll Want to Tweak

Apart from the more obvious settings above, Facebook has implemented a few features that aren't as well-known. Some are a bit privacy-invading, and need to be turned off, while others are good for your privacy but have to be turned on (nice job, Facebook). Here are the ones you'll want to keep an eye out for.

Turn Off Facebook Places

The Always Up-to-Date Guide to Managing Your Facebook Privacy Facebook's Places feature allows you to "check in" to businesses and other places on a digital map, so people can see where you are. This is a huge privacy issue, and while the act of checking in is done manually (Facebook won't automatically share your location with people), it's still worth turning off entirely if you aren't going to use it. You never know when a Facebook bug might surface or when you might just hit the wrong button and share your location with everyone you know.
To turn it off, just head back into your Privacy Settings and hit the "Customize Settings" link under the table. Scroll down to "Things I Share" and set "Places I check in" to "Only Me", which will keep Facebook from sharing your location with anyone. You also might as well Disable the "Include me in 'People Here Now'" setting while you're at it, which is right below the "Places I check in" setting.
You'll also definitely want to go to "Things Others Share" and disable the "Friends can check me into Places" setting, which stops your friends from sharing your location from their account. By default, this should be off for most people, but it's probably a good idea to double-check.

Turn Off Facial Recognition

The Always Up-to-Date Guide to Managing Your Facebook Privacy Facebook has also added a feature that scans newly uploaded photos for familiar faces. If it matches your face to one of their photos, it will prompt them to tag you in it. If you'd rather not have this feature on, you'll need to head into your Privacy Settings and once again click the "Customize Settings" link at the bottom of the table. This time, scroll down to "Things Others Share" and disable the "Suggest Photos of Me to Friends" feature.

Turn On HTTPS to Lock Down Your Private Information

With privacy-invading apps like previously mentioned Firesheep out there, it's more important than ever to secure yourself on web sites that have personal information on them, like Facebook. HTTPS will protect you from a lot of outside attacks, especially when you're browsing on open Wi-Fi networks.
The Always Up-to-Date Guide to Managing Your Facebook Privacy To enable HTTPS encryption, hit "Account" in the upper-right hand corner of any Facebook page and go to "Account Settings". Under "Account Security", check the box that says "Browser Facebook on a secure connection (https) whenever possible". Be sure to save. From then on, it will automatically connect to Facebook via HTTPS whenever possible. Note that Facebook applications still do not have HTTPS support (just one more reason not to use them).

Turn On Two-Factor Authentication to Keep Others from Logging Into Your Account

The Always Up-to-Date Guide to Managing Your Facebook PrivacyOf course, none of this matters if someone gets a hold of your Facebook password. If you want to make sure you're the only one logging into your account, you can enable two-factor authentication, which will send a code to your phone every time you access your account from a new computer or device. That way, if someone gets your password and tries to log in from your computer, they won't be able to get in unless they've also stolen your computer (or your phone).
To enable this feature, head to your Account Settings and scroll down to Account Security. Under "Login Approvals", check the box that says "Require me to enter a security code sent to my phone". That way, you'll get a notification every time a new device tries to access your account, and if it's you, you can plug in the code to get access.

Extensions and Tools That Enhance Your Privacy Even More

These are all great, but there are a few Facebook annoyances that you can't fix from your account settings. Thankfully, you can pick up a few browser extensions that'll help you out. Here are some we recommend.

Facebook Disconnect

The Always Up-to-Date Guide to Managing Your Facebook PrivacyEven if you love Facebook, it can get kind of annoying seeing that "Like" button all over the web. If you'd like to clean up the Facebook clutter on other web sites, previously mentioned Facebook Disconnect for Google Chrome will remove the Like button from most of the web sites you visit. There might still be Facebook links and icons, but it'll remove the actual Facebook integration people build into their sites, which is usually the more obnoxious clutter.

AdBlock Plus

The Always Up-to-Date Guide to Managing Your Facebook PrivacyA lot of sites around the net, like Pandora, Yelp, or Microsoft Docs.com, will try to connect to your open Facebook accounts and use them to "enhance" your experience. This can get really annoying, especially since it does it all automatically, without asking. We disabled some of these when we turned off the Instant Personalization Program, but bugs happen, and if you'd like to keep Facebook separate from your other online accounts, you can just download AdBlock Plus for Firefox or Chrome and add the following filters:
From then on, other sites shouldn't be able to use your currently-logged-in Facebook account to add "features" (also known as: spam) to other online services.

F.B. Purity and Better Facebook

The Always Up-to-Date Guide to Managing Your Facebook PrivacyPreviously mentioned F.B. Purity is a userscript for most browsers that will hide annoying Facebook applications and news feed updates, like Farmville, Horoscopes, and other ridiculous spam. Previously mentioned Better Facebook also has this ability, but it's much more complicated. If you just want to hide the spam, go with F.B. Purity, but if you want some serious, fine-grained control over your Facebook experience (along with quite a few extra features), Better Facebook is definitely worth a look.
While they don't boost your privacy per se, they will get rid of a lot of the annoying spam on Facebook and, in turn, keep you from accidentally clicking on something you shouldn't. Plus, they just provide a cleaner experience.

Internet Shame Insurance

The Always Up-to-Date Guide to Managing Your Facebook PrivacyFacebook's privacy settings can be pretty cryptic, and while you may have gone through your privacy settings like a hawk, you can still miss things. Our own Adam Pash's Internet Shame Insurance extension for Chrome puts Facebook privacy into plain English. Whenever you go to make a post on Facebook, it'll tell you exactly who can see it, saving you from making any embarrassing Weiner-caliber updates.

This should help keep your Facebook a little more locked down, like it was when you first signed up for it. These features are always changing, though, so we'll update the post whenever Facebook adds something new. We'll also put that info on the front page of Lifehacker as it happens, but it's a good idea to run through this guide ever few months just to make sure you've caught everything, since there is a lot of info here. Also, if we've missed anything, be sure to let us know in the comments, and we'll add it to the post.
