Comment Unpopular opinion: But this is just dangerous (Score 1) 69

Full disclosure: I design Class IIb medical equipment for a living and our (really old) manuals are on the site as well. I really love ifixit when it comes down to tear-downs of phones or game consoles, but when I noticed last month they published these service manuals I just thought: "this is insane and really dangerous". I know due to COVID-19, repairs were difficult since access to facilities were blocked and exemptions should be made, but publishing these service manuals online so that your average washing machine repair guy can "try" and repair a medical device is dangerous. The company I work for requires a hands-on training for all repair technicians for the devices we make, and for good reason. Most modern medical devices are complex machines which require proper tools to service and re-certify. A faulty repair can at the least compromise the "essential performance" of the device and at worst kill people. Even trained technicians screw up but at least you minimized the chance of this happening due proper training. Besides the liability point of view (burden of proof will be on the manufacturer) this can be damaging to the general patient population. If the hospital or outpatient clinic decides to save money by going with the cheaper unlicensed (read untrained) service shop there is no guarantee that the repairs are done properly. Most manufacturer these days earn their money on initial sale and disposables, service is just the extra's but you get what you pay for. Basic example: Cheap service shop repairs a medical device as a side gig but fails to properly reconnect all the Protective Earth parts during reassembly. Normally after repairs you would do a full EST review but they are a cheap shop, they skip on the expensive testing tools (like a Electrical Safety Tester) that can test stuff like patient leakage or Earth bonding test. Device is put back into service but accidentally zaps a operator/patient during use due unconnected PE parts. If it was Functional Earth it might not zap anyone but screw up any measurement the device needs to do (erroneous readings) Basic example 2: John Doe (hospital tech), downloaded the service manual of a malfunctioning device. Reads the troubleshooting guide and wiggles some parts and pokes some software parameters in the service menu changing the calibration settings. YaY, the error they were experiencing goes away, back into general use. But the calibration parameters were controlling the flow control of an IVU. Its now give double the output that the is shown on the screen. Nobody will know, since they tech does not have a flow control calibration tool.... until someone dies over overdose. Would you want to have an untrained tech working on a commercial airplane that you fly on and your life depends on its properly operation? I guess you wouldn't, same goes for medical equipment. Side note, which is commercially oriented. Service manuals usually contain complete schematics and BOM of devices for repair purposes. If your device does not heavily rely on software, your competition just got free industrial espionage handed to them making it trivial to copy your device.

Comment Learn How to automate your job yourself (Score 0) 228

Basically, if your job can be automated simply, you are replaceable by a high school kid with computer experience. Sorry that's just the way it is. Either of the options: automation or kid, would suck for you. Thus this means you should learn and improve yourself before this happens. I agree with the other comments that you should learn to do the automation yourself. Yes your job disappears but most likely you become a more valuable resource to the company. Either in maintenance of the automation tools or other automation tasks.

Submission + - Jeremy Hammond of LulzSec Pleads Guilty to Stratfor Attack (salon.com)

eldavojohn writes: After facing thirty years to life imprisonment and pleading not guilty to charges last year, Jeremy Hammond has pleaded guilty to his alleged involvement in Anonymous' hacking of Stratfor. The self proclaimed hacktivist member of LulzSec who has compared himself to the late Aaron Swartz explained his reasoning in his plea: "Today I pleaded guilty to one count of violating the Computer Fraud and Abuse Act. This was a very difficult decision. I hope this statement will explain my reasoning. I believe in the power of the truth. In keeping with that, I do not want to hide what I did or to shy away from my actions. This non-cooperating plea agreement frees me to tell the world what I did and why, without exposing any tactics or information to the government and without jeopardizing the lives and well-being of other activists on and offline. During the past 15 months I have been relatively quiet about the specifics of my case as I worked with my lawyers to review the discovery and figure out the best legal strategy. There were numerous problems with the government’s case, including the credibility of FBI informant Hector Monsegur. However, because prosecutors stacked the charges with inflated damages figures, I was looking at a sentencing guideline range of over 30 years if I lost at trial. I have wonderful lawyers and an amazing community of people on the outside who support me. None of that changes the fact that I was likely to lose at trial. But, even if I was found not guilty at trial, the government claimed that there were eight other outstanding indictments against me from jurisdictions scattered throughout the country. If I had won this trial I would likely have been shipped across the country to face new but similar charges in a different district. The process might have repeated indefinitely. Ultimately I decided that the most practical route was to accept this plea with a maximum of a ten year sentence and immunity from prosecution in every federal court. Now that I have pleaded guilty it is a relief to be able to say that I did work with Anonymous to hack Stratfor, among other websites. Those others included military and police equipment suppliers, private intelligence and information security firms, and law enforcement agencies. I did this because I believe people have a right to know what governments and corporations are doing behind closed doors. I did what I believe is right."

Comment Stupid yes, dangerous doubtful. (Score 1) 761

I work with laser daily that have far greater power and focus than the average 5mW laser you can buy in a store. And this report just makes me sad. Sending a guy to jail for something stupid. The pilots could never have been blinded (permanently or even for a short while) with laser of these low power unfocused types. Its basically more dangerous to your retina to look into the sun. The IEC 60601-2-22 for example defines a way to calculate the NOHD http://www.laserpointersafety.com/safetyinfo/safetyinfo/calcs.html Basically this a method of calculating the chance of damage to the eye, based on distance, divergence of the beam, power and wavelength.
Example:EXAMPLE 1: In the U.S., lasers sold as pointers must be less than 5 mW. A typical divergence is 1 milliradian. What is the Nominal Ocular Hazard Distance? The 50/50 injury chance distance?
NOHD (Nominal Ocular Hazard Distance) in feet = (32.8 / 1) * (square root of (0.5 * 5)) = 32.8 * (square root of 2.5) = 32.8 * 1.58 = 51.9 feet ED50 distance in feet = 51.9 / 3.16 = 16.4 feet
Answer: The Nominal Ocular Hazard Distance of a 5 mW laser pointer with 1 mrad divergence is 51.9 feet. The ED50 distance means that if a person is 16.4 feet from the laser and is exposed under laboratory conditions (the laser and eye are fixed relative to each other), there is a 50/50 chance of causing a minimally detectable retinal lesion.
In short, unless the guy was sitting within 16 feet of the plane/helicopter, he has a 50% change of inducing ANY form of damage to the retina. On the other hand, could the laser pointer pose a distraction to the pilot and the pilot could make a fatal error. Sure, but a ringing cellphone might do the same.

I have spent a huge amount of time working on the tty stuff trying to gradually get it sane without breaking anything and fixing security holes along the way as they came up. I spent the past two evenings working on the tty regressions. However I've had enough. If you think that problem is easy to fix you fix it. Have fun. I've zapped the tty merge queue so anyone with patches for the tty layer can send them to the new maintainer. --- MAINTAINERS~ 2009-07-23 15:36:41.000000000 +0100 +++ MAINTAINERS 2009-07-28 20:09:32.200685827 +0100 @@ -5815,10 +5815,7 @@ S: Maintained TTY LAYER -P: Alan Cox -M: alan@lxorguk.ukuu.org.uk -S: Maintained -T: stgit http://zeniv.linux.org.uk/~alan/ttydev/ +S: Unmaintained F: drivers/char/tty_* F: drivers/serial/serial_core.c F: include/linux/serial_core.h

Journal SPAM: Vanuatu cargo cult marks 50 years 2

Residents of the South Pacific island of Tanna worship an American "messiah" named John Frum who first appeared to them in the 1930s. According to a village elder quoted in a recent Smithsonian article, John promised to someday return and "he'll bring planeloads and shiploads of cargo to us from America if we pray to him.
