jjp··on Leaked Catalog Reveals a Vast Array of Military Spy Gear Offered to U.S. Police
Page 7 doesn't detail how it works, but does seem to describe what it does. From cell base station creates a connection to a target cell phone without the user of the cell phone being aware. Can then use RF direction finding to identify location of cell phone. Obviously multiple base stations required to be more accurate.

jjp··on Ask HN: What are good ways to find startup problems to solve?
Thoughts on how to push through

1. Pick an industry that you are either interested in and/or you believe is going to be more profitable - i.e. financial services pay more than retail therefore more potential.

2. Take a friend from University who works in that industry and not in technology to dinner, beer, coffee and find out what aspects of their job they find are the biggest PITA.

3. Read up what the management consultants are talking about. Not they should be considered gospel on problem or solution but if they are trying to sell something they believe there is a) problem that exists in that industry, b) there is a market for a solution and c) the industry is buying that solution.

4. Read up what your potential competitors are doing about the problem

5. Go to your thinking space (mines the movies) and noodle.

6. Compare your idea to the knowledge you've acquired in 2,3 and 4.

You can bail out at any point, you can do 1 through 4 in any order but do them before 5 and 6. You can be running multiple problems in parallel and you'll probably end up with ideas that coalesce. Then when you've got to step 6 make a decision about whether you're still interested in the problem, because now comes the hard work.

jjp··on Ask HN: What are good ways to find startup problems to solve?
From your follow-on comments I'm not sure whether the challenge for you is finding problems or identifying that it's a problem that is worth working on. Providing a little more information on the sort of problems you have seen and then why you have decided to not work on them would help others be more specific with their guidance.
jjp··on Frequent password changes are the enemy of security
> I am a bit shocked, that they want to keep old passwords.

Presumably that is required to stop simple password rotation of Password1, Password2, Passsword1

> why brother with the ones that doesn't work?

That's going to depend what the attack is against. If it's a consumer facing web site then you're probably right and the attacker will move right along unless it's a high profile account (Zuckerberg et al). If it's an internal system then attack is probably more interested in named accounts/roles and spending a few seconds to workout whether the password is an easily decipherable sequence will quickly pay off.

jjp··on Protecting Free Speech: Why Yelp Is Marking Businesses That Sue Their Customers
It would be really helpful to also see the reviewers summary. Then that way I could see if the reviewer is usually balanced or positive then a negative review has more weight whereas if you are a serial bad mouther I can more easily discount your opinion.

jjp··on We Should Not Accept Scientific Results That Have Not Been Repeated
> Now, straight to the point, who's going to pay for the repeated research to prove the first one?

Who is and who should are two different questions. The body who funded the original research should be best placed to fund the verification of the research. If the research isn't compelling enough to fund verification then why was it funded in the first place? And if the principle research group is requesting additional funding for more research that builds on the initial unverified research then that sounds like poor governance.

I realise that this simplistic view gets messy and confused when research is really academic led innovation and incubation.

jjp··on Why DHCP Lease Expiration Matters for Your Coffee Shop Router
Yep and the 10.0.0.0 on an Airport killed my wife's VPN as it couldn't route as expected and then I wasted half a day trying to figure out what might be wrong on a completely locked down desktop after 1st line support gave up and said it should work must be a problem with your wifi.

jjp··on Escaped robot holds up traffic in Russia
> Testing involves testing of the autonomous movement of the robot, this robot was not carried under control.... We discovered the disappearance after about 40 minutes.

Interesting that the robot was being tested but not being observed to see whether it was behaving as expected. I'd like to be able to do more testing like that.

jjp··on Google praises 86-year-old for polite internet searches
I've had to become politer trying to instruct Siri as realised my children were copying my style of question. I wasn't swearing, just being sarcastic at lack of recognition and I didn't want to encourage that.
jjp··on jQuery 3.0 Released
Would probably mean that we have multiple libraries or frameworks developed (to various levels of completeness) that sit above the different browser runtime implementations of the jQuery API in order to handle the challenges of having the browser runtime not supporting, only partial supporting or incorrectly supporting the jQUery API specification.

jjp··on Ask HN: Anyone making a living off of desktop applications?
This feels to me like there are a few other questions to ask: - do your target users have a preference for desktop vs webapp? - can you achieve everything you want in desktop vs webapp? - How do similar solutions from competitors deliver? How would you differentiate? - do you have the skills/time/inclination to provide desktop support when a user can't get your software working with Win XP and a badly written printer driver? - What's the pricing model you will use with lone users? Sell once, sell once and then try and sell upgrade; subscription?
jjp··on Ephemeral is developing tattoo ink designed to disappear after a year
> On one hand, this invention will keep a lot of people from making the very common mistake of getting ink they don't like and can't remove.

Not sure that it will change an often spur of the moment, possibly rebellious or first love, decision. When asked the question do you want it in permanent ink I still think the answer will be mostly yes.

jjp··on Weeding the Worst Library Books
No recommendation for a good public library. For pre-purchase of a reference book if it's current find the right bookshop and you could always do that way. Many universities offer access to their libraries. UCL access policy [1], City University Library [2]
