/me hates wifi hackers!!

Actually, wifi hacking of home wlans isn't really a big security issue anymore. I dare say 99% of people who get hacked via wifi have it occur in public places. There was a time when hackers would cruise around in their cars looking for wlans to crack. But the tremendous proliferations of wlans makes that pretty much a thing of the past. But having someone try to hack your laptop or tablet while you're having coffee connected to a pubic wifi spot, is much more likely.

 

So, if you've learned to lock down your computer for use in public wifi spots, where the wlan is, by definition, open to everybody, then you should be safe at home no matter what encryption you use. Locking down your device, by using Linux, is far far more important that choosing WPA2 encryption over WEP. Like I said, the only difference between the two is just a matter of how long it takes to crack one over the other. Just google "cracking WPA2" and you'll find plenty of articles with step by step instructions on how to do it.

I knew WEP and WPA were crackable. I thought WPA2 was not cracked outside a dictionary attack (brute force). My understanding was with a sufficiently long and random key would be extremely secure.

Good info in your clip Fran. I just set up broadband for me mum with TalkTalk and her wireless router from them comes with WPA2. I managed to hammer out the same deal for her that I have and she is as happy as Larry phoning all her chums abroad for free. In all the three conversations I earwigged on her chums showed some concern at the cost of the lengthy call, me mum casually told them that she had negotiated a deal with a new telephone supplier and that all her calls were free.She sounded really happy, don't know if it was the no cost call or the feather in her cap for having such a deal. :Laughing:

Lol! Good for you, abarbarian!

 

This month's Linux J our all is all about the pi! including clustering. The opening pages is the results of a survey on how do you use it? So many things from dvr to sound system to web hosting!

 

Ps

I am not correcting this iPad's auto correct. It's too much of a fight...

For all you photographers,

 

 

 

 

Gigapi: a Raspberry Pi rig for gigapixel photography

 

 

 

But if you’re not in charge of a defence silo, you can still take your own gigapixel images by stitching together many megapixel-sized images from an SLR camera on a motorised mount into a giant, seamless mosaic with very fine detail. You’ll need something approaching a defence budget if you’re going to do this yourself without building your own hardware, though; I spent a few seconds googling and found that off-the-shelf motorised rigs for your camera can cost nearly $1000.

Tim and Jack Stocker thought this was daft, so they built their own out of MDF, some Lego turntables, and a Pi with a cheap stepper motor attached.

 

Here is the site if you want to make your own

I finally got online with my raspberry pi. I was waiting for all the extras I ordered to go with it. New red acrylic case from these guys, a roll up keyboard and a super cheap mouse from Amazon as well as a Patriot 32gb SDHC card. I had a D-Link Wireless N USB Adapter (DWA-130) kicking around and a no name usb hub. The wireless worked like a charm. The roll up keyboard is a bit annoying and I suspect I really need to get a better usb hub with its own power source as it seemed to run a bit slow. I installed Raspbian Wheezy on the SD card. Now I have to figure out what I want to do with it, so many ideas to choose from.

You will soon find some use for the Pi. Keep an eye on this site and you will spot a funky idea to suit sooner or later.

The roll up looks an amazing idea but seems to not be so good in real life from the reviews I read at Amazon. I have been looking at getting a wireless mini kb with trackpad for a while now but keep on getting put of by buyers reviews.

 

You will need a powered hub if you are running more than a kb and mouse.

 

At the moment I am just using my Pi to surf the web and play video clips and pics when I am at me mums. With a bit of tinkering thrown in aswell. I do have some projects in mind but I need to find some spare time to play.

 

Have fun with the pie making. :shifty:

What kind of USB power supply are you using? If your keyboard is acting up it is the first sign of power issues.

It's not really that the keyboard acts up so much as the keys are spongy(?) and the layout is a little strange. You kind of have to really smash the keys sometimes to type. The usb hub I have doesn't have a power supply at all so I have to replace it.

I have one of those keyboards too. It is so old it has a PS/2 connector. I know what you mean about the spongy keys. I bought it to connect to a laptop. I kept my laptop safely away from my coffee cup because I did not want an accident and was willing to put up with the spongy keys so I could compute and drink coffee. :th_thtante:

I agree. The keyboard I have for my Pi is not very good either. Logitech K400. It is wireless and works week aside from the sponginess.

 

I wish dell mad a simple wireless keyboard based on their normal keyboards and not a slim keyboard.

I thought the roll up one would be good for the little one to use because it wouldn't matter if she spilled stuff on it.

 

I had to replace the keyboard for my PC a year or so ago and it is fine except when I want a capital letter, then I have to make sure to jam the caps lock key down and hit the letter I want capitalized really hard. The letter i seems to be the worst one, beyond annoying but I'm too cheap to replace it yet. I have other keyboards kicking around but they have the PS/2 connectors and I'd need an adapter.

I got me an empty large plastic water cooler bottle about fifteen years ago with the intention of filling it with loose change an then buying meself a huge treat. I never got more than an inch or two of the bottom covered as I kept on dipping into it. So today I emptied it and took the swag to the local store which has a change converter machine. Shocked I was when I looked at the total, £42.57. Recovering quickly I dashed home and ordered one of the Pi cameras that will be on sale tomorrow. I'd had a early interested party e-mail from Farnell earlier in the day hence the hunt for loot.Whilst I was in town I took the opportunity to bank a cheque I received yesterday from the local scrap yard where I had taken a trailer load of scrap to weigh in. £15 I got for a load of old tat that folk have over the last few years have paid me small amounts of loot to dispose of. I was shocked to discover that Farnell's were wanting to charging £4 more than RS for my order. What order you say,thought you were only getting a camera ? Did I not mention a camera ? How remiss of me.I just did a quick proof read and I did mention a camera, I thought I had.Anyways, adding up £15+£42.57=£57.57 which was less than Farnell wanted but more than RS wanted I spent the difference on a chicken wellington which was reduced to half price and a glorious fresh cream horn.So here I sit well fed and watered, I found a half bottle of mulled wine at the back of a cupboard this evening, feet up and waiting. Me version B latest model Pi with translucent case and camera module should arrive in a few days time. I should have recovered from todays exertions by then.

I'll post pics.

Just been reading through the RaspiCamDocs. This looks like some piece of kit.

You have a shipment being sent from RS COMPONENTS LTD that is due to be despatched on 15/05/2013 using our Express 24 service.

 

Looks like it may arrive today. :bounce:

The new Pi works fine and so does the wi-fi dongle. Can not say about the Pi camera as I can not get it set up.

 

I have used the firmware update hack, just last week as it happens. I had to do that to get the wi-fi working as well as update and upgrade for the os.

 

Today update and upgrade run but call errors on some web addys then tell me the system is up to date apart from three programs. The firmware upgrade hack complains it can not find a webb addy and refuses to run.

 

Spent hours doing initial reading to make sure things ran smoothly. Read loads of post about how goody the camera was and loads of I'll show you my vids I made.

Checked re checked everything I did and the only conclusion I can come up with is there is something wrong with the servers I am trying to access. Maybe they are down for maintenance or something.

Anyway I'm hacked of. The bunch of lilies I bought at the bud stage are now almost fully open. Great. No blooming timelapse video of them.

Still the same old rubbish.

 

Tried "update" "upgrade" "rpi-update" and then,

 

sudo raspi.config

 

I get (not typing everything)

 

 

Could not resolve "mirrordirector,raspbian.org"

Could not resolve "archive.raspberrypi.org"

Failed to fetch ---etc etc etc

Some index files failed to download.

raspi.config is already the newest available

 

"raspi.config is already the newest available" which is a load of cobblers as mine does not have an option to activate the camera.

 

My version of Raspbian should upgrade. I did a firmware and system upgrade last week to get the wi-fi working.So I have no idea what is wrong.Am now super hacked off.

There you are pictures as promised. Taken with my Cannon not the Pi.So I told a porky about all the flowers being opened and the planned shots ruined. Call it poetic licence. The kitchen smells divine and will only get better as more buds open. Life eh. :breakfast:

Pi camera Day Three

 

Still the same old same old.

 

Came across this chap who had a similar problem over at the pi forums. Seems he solved his problem by using a different card. What madness is that !!! You have a sd card that works fine with Raspbian but does not work with Raspbian and the camera.Freaking madness, especially as there is no official announcement about what I would consider to be a rather important bit of information.Nice introduction for the kids to the world of linux.

 

http://www.raspberrypi.org/phpBB3/viewtopic.php?f=43&t=44204

 

Greetings! Model B user, downloaded the latest version of the OS this morning, went through the instructions, did the following :

 

sudo apt-get update

 

sudo apt-get upgrade

 

rebooted

 

Expanded FS

 

rebooted

 

Doesn't show the camera as an option in the configuration when it reboots. I've formatted the SD card 3 times now and started from scratch, and I can't get it to show the camera as an option. It's plugged in the right direction, it's all been handled very carefully. I did get some errors on an update, telling me that it failed to contact InRelease on a number of things.

 

B)

 

Can you tell that I am even more hacked of than yesterday. :breakfast:
