Nope. Wired presents this as if its a blanket exception for everything, its not.

http://ifixit.org/blog/7475/repair-coalition-wins-exemptions... is a bit more clear on the types of things that will be allowed under this.

As for the specifics of jailbreaking:

"The Register also confirmed that the exemption for gamers should not extend to jailbreaking of console software because such jailbreaking is strongly associated with video game piracy."

The purpose of the hashes isn't to prove the file hasn't been tampered with, its confirm that the file wasn't corrupted during download.

Actually, this demo would be stopped if the stack protector was on. The demo relies upon overwriting the return pointer that controls where the function jumps to upon returning.

The stack protector acts as a guard against overwriting that value without knowing a key that is stored elsewhere in memory. You'd need some memory disclosure issue to get the key or brute force the key.

As long as you use prepared statements correctly.

I can't tell you how many times I've seen someone passing a query though the prepared query method but still crafting the query dynamically

Stuff like:

prepareQuery("SELECT something FROM table WHERE col='"+userInput+"' and otherCol=?", otherUserInput);

That is still vulnerable even though prepared statements are in use. As long as user input doesn't find its way into the query string though you should be safe from these assuming the issue isn't internal like bad stored procedures creating queries based on input.

I know you're making a joke but a passpoem or a passstory for lack of a better word is usable and something I do.

I take a passage of reasonable length from a book that I've memorized, could be song lyrics or anything though. Then to create a password I take the first several words to make a password roughly the length I want, do a standard transformation on it that results in a string with numbers and special characters and use that as a password.

When I need to change my password, I just take the next phrase from the passage and apply the same transformation. This has the distinct ability of letting me go back in time and remember what password I would have used at a certain time which has come in handy for remembering the root password on an old server.

My bad, death:summit is correct.

And I don't accept the echo-chamber consensus opinion of mountaineers that it's all worth it in the end.

I'm not sure what mountaineers you've talked to but most I know don't like the current state of Everest and how its become a tourist attraction. Most I know support the restriction Nepal is considering of restricting permits to those who have climbing experience on other significant peaks.

Honestly, I don't think anyone really has any business up there.

Well, no one has any business being up on any mountain; yet we do it.

you can find better, more challenging climbs that are still safer.

Yes and no. Though your statement is true I'm not sure you realize how safe Everest is. Everest has about a 4% death to summit ratio. Though its not the lowest rate among the 8000m peaks considering the masses of inexperienced climbers who climb Everest the fact its so low is amazing to me. If Everest was climbed by the same type of people who tackle K2 or Nanga Parbat (26.5% and 20.3% death:summit) I'd imagine the ratio would be significantly lower on Everest. Even so, Everest has a low fatality rate.

However, it is also not technically challenging (the challenge is the altitude not the climbing) so because of that finding something more challenging and safer shouldn't be a problem.

Its also worth mentioning that there is more than one route up Everest, the Southern Col is the most popular and easiest and thus sees the traffic jams up Lhotse face and at Hillary's Step. Other routes don't see the same traffic.

There are risks but the last couple years have been exceptionally deadly.

Prior to 2014 the deadliest day was May 11, 1996 (8 deaths). In the 1997 through 2013 seasons the average season death count was only 5 with a median of 4 compared to 22 in 2015 and 17 in 2014.

Adding to this, if people want a lonely long hiking trail the Continental Divide is a good choice. My longest period without seeing another person at all was 6days, and I know several who have gone went weeks without seeing anyone(apart from hitchhiking into town for more food).

Its also just a really awesome trail (Montana/Wyoming/Colorado/New Mexico) with on a good year maybe 300 hikers starting(far fewer finishing or making significant progress)

Though it does take map and compass navigation as the trail is not complete and even when it is, there often isn't a trail just a line on a map.

There are competitors, just in terms of the major long trails of the USA, there is the Pacific Crest(PCT) and the Continental Divide (CDT) those three make up the Triple Crown of long distance hiking in the USA ( http://aldhawest.org/triple-crown/ )

And several others; https://en.wikipedia.org/wiki/Long-distance_trails_in_the_Un...

I'd say the PCT is its closest competitor as the PCT is considerable well marked, but its an easier trail grade to hike(and on the other side of the country)

If you want remoteness and untouched wilderness, I went days without seeing another person (and some hikers can go weeks depending on the year) on the CDT at all though some extraordinarily beautiful locations. Of course its not as defined as the PCT or AT(compass navigation is requires as the trail doesn't always exist)

The thing about the AT is it is the most accessible of any of the major trails, I've heard that about half the US population is within a 1day drive of some point of the trail.

You don't have to run the executable. You can, but the problem is absolutely doable without running it (static reversing).

As for the subdomains, you can safely ignore them. There are a number of them most are not primarily mine. I just give some friends free hosting(or point subdomains to their boxes)

And yea there are random subdomains that are not part of it. Most of the subdomains are not even mine (I give free hosting to friends). The only subdomain that was part of it was clcs.0x0539.net but thats no longer the case.

Everything you need to figure it out is on the login page.

Consider how hackernews works, there is the login page but that is not the only means to authenticating. You don't after all have to type your user/pass out for every page request.

Oh sorry, that is a side-effect from bringing it back the domain was slightly different.

As for the login page, sometimes the way in is not through the front door.

Its a classic alright but being a classic just a warning to everyone some of it does require going back in time a little bit like dealing with a 16bit binary.

If this type stuff interests any of you but is too hard, give mine a try ( 0x0539.net ). It is not intended to be a significant challenge, instead all the stages focus on introducing some basic concept related to offensive security. Its mostly aimed at some young teens that have expressed an interest in learning that stuff rather so the target is very introductory.

I update the site every so often with new sets of challenges and rotate through former sets if someone requests it. The current one I ran for a bit in 2013 and then brought it back earlier this year and plan to cycle in a new binary exploitation focused one in December.

OSX should be doing the context switch also.

The added penalty is a switch to usermode to read userland data, then a switch back to kernel to continue on...its just additional context switches for reading userland memory

I've not graduated yet as I started in 2009 and just take courses every now and again instead of doing it all at once, I'm completing my last term this fall.

First year with C++ and C. The C++ usage was C-style code just used cout/cin/booleans.

Second year was C, Forth(had to write an interpreter) MIPS32, Java, and Objective-C(Elective in iPhone dev[pre-iOS days])

Third year: C, Java, Haskell, Prolog

Fourth Year: Matlab, C, whatever you want. Most 4th year courses are either fairly specific or you're free to use any language you want. Ex. the Computer Vision course uses Matlab, but the AI course you could use whatever language you wanted provided you supplied steps for running it that the marker could follow.

Yes its quite common now. Working in my high schools theater which was the largest in the town we'd get these types of requests so I imagine in they would be even more common for something that mattered

I don't know of any official revelation but I did get a little insight into the amount of vacation taken at the company I work for when I had taken 'significantly more' vacation than the rest of my coworkers.

The most anyone else took was around the 4 weeks mark. I had taken a little over 6 weeks and that was the upper limit that had my boss telling me I was taking too much vacation. I felt a little shafted by than since my last job was 5 weeks + sick time + bank holidays.

So that's not a lot of information for you but that would confirm your suspicion that it is less. That said it does not translate to unlimited work hours but our work is contract work. We get contracted out to other companies so though we are expected to get the work done and sometimes work >8 hours the expectation is that it will average out to 8hours a day. Be it 4hours one day followed by two 10 hours days or what have you.
