Do you mean you're trying to create a duplicate of the original wireless control unit? If so, you need to know what radio frequency, encoding and protocol it uses. This strikes me as the sort of data that the manufacturer is likely to want to keep secret to make it harder for people to break into their systems, so it might not be easy to find.

If the remote start unit has any way to trigger it locally, you do have the option of implementing your own wireless protocol. Obviously you'd be responsible for any legality, security or safety issues that introduced.

Most of these systems use a rolling code setup for authentication, so using a secondary wireless transmitter/receiver is probably the best option.

In the end, the consumers win. Drug users get cheaper and better drugs
One of the things that bothers me, is that I don't see anyone claiming that drugs will actually get cheaper.  There's a lot of chortling by municipalities about all the money that will collected in taxes instead of going to the criminal infrastructure, but if the end user price doesn't go down, you're still looking at a bunch of people with increasingly expensive habits to feed, and increasing inability to hold down a steady job.  Maybe.  On the plus side, it can't be much worse that alcohol or tobacco.   On the minus side, alcohol and tobacco are really pretty bad.  I mean, I can find websites that estimate that we could save about 8billion in "enforcement costs", and make 7billion in tax revenue by legalizing pot.  That sounds really good till you also find the websites that estimate the societal cost of alcohol abuse at upwards of $100billion/year.  (similar estimates for smoking, except "smokers die some 10 years earlier than nonsmokers, according to the CDC, and those premature deaths provide a savings to Medicare, Social Security, private pensions and other programs.")

I can see that. I assumed that drugs would get cheaper due to manufacturing improvements lowering the cost to produce them. Drug companies may just decide to increase the price, or government red tape may force the price up. However, if the taxes force the price of the legal product high enough, people will turn back to the illegal drug dealers and tax revenues will plummet.

Personally, if we're going to have a "war on drugs", i'd like to see it adhere to the articles of war. See a drug dealer on the street? That's an enemy combatant, shoot on sight.  This half-*** attempt at a war is just wasting money with little to no return.

Do law enforcement agencies and police really want to end it?

I'm not convinced they do!  For example,  if the police/DEA government simply issued out tv adverts, posters, billboard etc.... saying "deal drugs legally with a license"

Phone number at the bottom, website...

You have until say jan 29th 2014 to submit your application, name, phone number, etc...


How many people who deal would sign up?


(Drug war over, every dealer out there just got caught)

You're thinking about it all wrong. Legalizing drugs would help drug dealers about as much as Wal-mart moving into a town helped local mom-and-pop stores. The drug dealers will get put out of business by big drug companies that have the ability to mass produce drugs, negotiate for lower license fees, ensure product quality, and distribute product globally.

In the end, the consumers win. Drug users get cheaper and better drugs, the government gets more tax money that it can waste on bull****, and the police get a month off while the criminals find the next get-rich quick enterprise now that selling drugs is unprofitable.

I did what they suggested and installed the bootstrap.dat file, which sped things up a bit. However in my case it took about two days to catch up. I presume it is validating all the blocks and that involves a lot of hashing.

However I did find that if you stop it in the middle and restart it, it remembers where it was (in one case my Mac crashed) so it seems OK in that respect.

I got the "green tick", but as you can see, I'm not rich yet:




Your client is synchronizing with the "blockchain" which is the thing you are working to crack. Its actually stored in a file on your PC, so once it is downloaded it only takes a minimal amount of time to keep up with all the blocks that have been solved.

Probably so all those folks would get a "you've been tagged in a photo" message from facebook.

Exactly. Facebook wanted people to spent more time on Facebook, so they removed almost all the notifications. You only get an email if someone tags you, so if you're not always idling on the page you will miss things your friends post.

Usually a phone call resolves those issues quickly enough. Often the thieves will try a small transaction first as a test. I remember two of the times the credit card company called me. One was a long distance call charged to the card (I assume some nominal amount), and the other was $10 charged at a bar on the other side of the country. Somehow they are good at catching those. I do obsessively check each statement (with the help of Quicken and a little additional automation), and I've never found a charge that we didn't make. So I hope you're worrying about a problem that hardly ever happens.

OTOH, given what the NSA has done to the encryption that secures our financial systems, perhaps you are correct to worry. Hmm.

Same here. I triggered the fraud detection on my card by ordering two small items from Chinese importers on eBay, then loaning my friend $700. The bank called me about 30 minutes after I made the $700 transfer.

I'd stay away from bitcoin mining unless you have loads of cash. The difficulty has gotten so high, you have zero chance of making any money with consumer hardware. Especially with businesses building large mining warehouses with ASIC miners. Litecoins are much better, You can still make a few coin a week ($60 - $100 USD) with a modern graphics card if you work in a mining pool.

Haha... wellll... I got one of those fancy 2nd-gen Intel SSDs that were supposed to be amazing.  Installed it in a rackmount computer that I used to do real-time audio effects processing for my band at the time.  Worked a treat for a while, and it was FAST!  Got to a gig, booted up, MISSING OPERATING SYSTEM.  Sooo no effects processing this gig. *grumble*

Took it back home, booted from the XP CD and reinstalled the bootloader.  Worked fine.  Then one practice session, I powered everything up and my BIOS reported an eight megabyte hard drive.....  8MB?  Kinda small even for an SSD.  OOoookay, no effects processing this practice either.  *grumble*

Took it out, brought it home, read there was a firmware update (which was likely to erase the contents, but it was little more than OS + software, so a minor hassle but no great loss), applied the new firmware, stuck it back in the computer, still showed up as an 8MB HDD.

At that point, I started using it as a drink coaster, where it has worked very well ever since.

I have an OCZ in my desktop at home which is running wonderfully.  A cheap I-don't-remember-what that I had before it that worked great most of the time, but every now and then writes would freeze for 30 seconds or so.  A Samsung for an on-the-go Linux mini-ITX build I haven't gotten a PSU for yet.  And I have an old Intel in my laptop that has been through the wringer and has never let me down.

I guess you never know.

You ran XP on an SSD? Thats a really BAD IDEA. XP does not support trim, and is horrible to SSDs (it likes to do lots of little write operations to burn them out as quickly as possible).

Put some traps out, put sensors on the traps, then the trap activation time will tell you when the mice were there.

How does this one qualify as a kickstarter project?


They made an "arty" video.

$250,000 to replace a black ink cartridge with a silver one. At least they aren't ripping people off on price, a $20 pledge gets you a pen and electronic thingy. They also seem to have a prototype, which I think is a Kickstarter requirement due to all the multimillion dollar vaporware projects.


Yep, still bitter.

"Professional-looking" is code for "impossible to use".

I know the sort of site they mean. Full of Flash widgets and little boxes that pop up as you mouse-over them. The page takes a minute or two to load, and fails on 3 out of 5 browsers because they only test it on one.

Actually, I think minimalism is in again, unless its out again and I didn't get the memo.


And any developer that still uses flash should be shot.

Just out of interest, how slow is "slow" and how "expensive"?

(I don't know how much my broadband should cost because we get phone and broadband free, and speed is in the range 45 -70Mbits-1)

Edit: I took a look at BT's infamously opaque pricing structure, and I think it comes in at about £40, 65 USD, or 48 euros per month. I should get BT Sport included, but can't be bothered.

Usually around 1.5/0.5 to 3.0/0.768 for roughly $30 - $40 USD per month. The price goes up ~$10 if you don't pay for a landline phone connection, or cable package (yes, they actually charge us more if we use fewer of their services). My issue isn't really the poor connection speeds/price, its the horrid infrastructure. US taxpayers have paid our big telcos several hundred million dollars on THREE separate occasions for the purpose of replacing the 50 year old copper network with fiber. This is because "its too expensive" for them to fund it themselves. On each occasion, they simply took the money and added it to their books to make their quarterly report look better. Nothing was built out, at all. Now their support requests are going through the roof, because the COTTON AND TAR insulation on the copper wires is crumbling off, so they want us to give them MORE money to fix it.

13 years ago I could get 7mbit/1mbit DSL from Verizon at my house. Now, at the same house, I can only get 3Mbit/0.5mbit DSL. My friend that lives two miles down the road can only get satellite. My other friend that lives in the second largest city in my state, can only get 3mbit/0.1mbit DSL, and its flaky as hell since the city copper is even older than the rural copper.

The state of Maine has bailed Fairpoint Telecom out of bankruptcy TWICE, because if they went under, we wouldn't have any phone service at all. They should be giving us access for free at this point.

We actually have a ton of third party fiber optic backbones in my state, because the big telcos have screwed it up so bad. If I bought a commercial property 1.3 miles down the road, I could get as many 10gig/10gig connections as I wanted (though i'd be looking at around $10,000 per month in costs). So its not like its impossible for the big telcos to get the bandwidth here.

Just did a little more research. Apparently the utilities that we use to reset EFI passwords aren't available to the public. Thats moronic, even by Apple standards. So...pray you have one with a PIN and not a 30 character alphanumeric password, I guess.
75  Using Arduino / Project Guidance / Re: Counter/Password Cracker on: November 13, 2013, 12:22:25 am
If you're trying to bruteforce the EFI password, good luck, those tend to be quite long, contain numbers, uppercase, lower case, and special characters (especially on Macbooks that have been "liberated" from educational institutions). The standard is about 30 characters. There are utilities to reset the EFI password. If you're trying to log into the Mac itself, there are boot disks that let you brute-force or reset the password.

Trying to brute-force a password in place is just dumb. Your little microprocessor is still going to be running numbers after the sun consumes the earth, its barely possible on a high-end x86 machine. Its much better to grab the encrypted passwords off the device and brute-force them on a machine you own (or using a cloud computing service).

Whats your reasoning for this? The EFI password doesn't protect any data, so theres no reason why you shouldn't just back up the files on the machine and reset the password with a new OS install.
