Automatically adjust your monitor settings to reduce eye strain

F.lux is an unusual tool which can automatically adjust your monitor's colour temperature to try and reduce eye strain.

Why bother? The theory is that computer displays are normally set up to display a harsh, blue light. This works fine during the day, but is too bright for night viewing, and could even promote sleep problems.

To avoid all this, F.lux uses your location, the date and time of day to figure out your sunrise and sunset times, then automatically adjusts your monitor's colour temperature to a more appropriate level.

To see what this might mean, click the blob representing the sun in the program's Settings dialog for a quick preview; it'll be at normal brightness levels during the day, but change to warmer, more orange/ yellow glow at night.

Click "Change Settings" and you can further customise the program to better suit your needs, by more accurately setting your location and deciding how quickly you want the colour temperature change to occur (it's annoyingly fast by default, but setting to "Slow" here will help).

And you can also adjust the colour temperature you'd prefer at day and night, but unless you're extremely sure what you're doing we'd recommend you try out the defaults for a while, first. The preview will show you what looks like a very extreme change, but in part that's because you're viewing it quickly, and all at a single time of day: it works much better in real life use.

F.lux won't be right for everyone. If you work both day and night at the same computer, though, in the same place, then it could be an effective tool. And the program includes no adware or other complications, so you can install and try it out without any hassles or problems.

Version 3.10 brings:

1.f.lux can go warmer than 3400K now, down to 2700K. Or even 1200K if you really want it to.
2.Support for color profiles from a hardware calibrator
3.Movie mode. This setting warms up your display, but it preserves shadow detail, skintones, and sky colors better than f.lux’s typical colors. It lasts 2½ hours, which lets you watch most feature films
4.Disable until morning, for late-night crunch mode
5.A new “darkroom” mode, which inverts colors and gets very red
6.A map to help you find your location
7.Hotkeys to dim your display (Alt-PgDn, Alt-PgUp) late at night, so desktop users can dim too
8.A hotkey to disable/enable f.lux quickly: Alt-End
9.If you have a laptop, f.lux gets warmer when your backlight dims, like an incandescent lamp
10.A simple schedule for Philips Hue, so you can f.lux your house


It won't work for everyone, but in some cases F.lux really can make your monitor more comfortable to view

WhatsApp Messenger 2.16.11

Free Full Commercial Software

WhatsApp Messenger is the world's most popular instant messaging app for smartphones.

You can use it to send and receive text and voice messages, photos, videos, even call your friends in other countries, and because it uses your phone's internet connection it might not cost you anything at all (depending on whether you'll pay data charges).

It's easy to set up and use. There's no need to create and remember new account names or pins because it works with your phone number, and uses your regular address book to find and connect you with friends who use WhatsApp already.

You can talk one-to-one or in group chats, and because you're always logged in there's no way to miss messages. Even if your phone is turned off, WhatsApp will save your messages and display them as soon as you're back online.

There's plenty more (location sharing, contact exchange, message broadcasting) and the app is free for a year, currently $0.99/ year afterwards.

What's new in 2.16.11?

 - Due to a bug in iOS 10, your notification sounds may not properly play until you restart your iPhone (press and hold the power and home buttons for 10 seconds).
- In groups, you can now mention specific people to get their attention by typing the @ symbol and choosing someone from the picker. 
- When forwarding messages, you can now send to multiple chats at once 
- Ask Siri to send WhatsApp messages or place WhatsApp calls (iOS 10+) 
- Answer WhatsApp calls right from your lock screen, just like a standard phone call (iOS 10+) 
- A new Widget lets you quickly jump to a recent chat or see which chats have unread messages (iOS 10+)
