Journal: 2+ port router+asterisk server? 14

Journal by drinkypoo

I need a new system on which to run asterisk, bonus points if I don't have to configure it from scratch. I'd like to spend less than $200 (ideally I'd pick up something used if necessary for $100) but I have storage devices available, whether CF, SD, USB, or what have you. It can have wireless, but it doesn't have to because I have a routerboard for that. I have found my pogoplugs to be unreliable at best.

Journal: The Trolls 81

Journal by Tom

Wow, it's been 15 years but I've finally got my own personal troll! :-)

I must apologize to everyone I've ever called a troll now that I've seen a real one. Yeah, there are trollish comments, but this... it's a different league. If you ever wondered who these brain-damaged morons were who set up geocities homepages with blinking purple text on blue background with red dots in Comic Sans - that kind of different league.

Now it does make me wonder about trolls in general. Has there been a study on this? I really wonder if psychologists have tackled this because quite honestly, you cannot be mentally stable and post in this and this content at the same time. So I do wonder if trolls on the Internet (the real trolls, not the people occasionally posting something stupid) do have a mental problem. It definitely looks like it. Probably insecurity issues, definitely an exaggerated need for attention, might be related to borderline syndrome or schizoprenia.

And, of course, the Internet provides:

As someone who has had to deal with family members suffering from mental illness, let me tell you that it's not funny. So despite the fact that they are, in fact, obnoxious, aggravating assholes, these sad little fucks also need help and their miserable little existence is not something you'd want to trade for yours, no matter how much you think your life sucks. Trust me, with a mental illness on top, it'll suck more.

Obviously, we can't offer therapy to people who usually comment anonymously and will often go to great lengths to avoid being tracked down. What we can do, however, is get a better understanding for how they act this way (they can't help it, mental illness is stronger than your conscious mind) and that the best thing we can do for them is to not continue the feedback loop. "Don't feed the trolls" - old wisdom there.

The last link in that list contains a few more ideas.

Now that I'm at the end, I kind of regret the smiley face at the top. But I'm leaving it in because this journal entry is a bit of a journey, even if it is short. Thanks to some Internet resources, a bit of research and connecting the dots, I've come a short way, changing my mind a little on this particular sub-sub-sub-part of life.

-----

A short additional statement on how to treat trolling. From what I've gathered from the resources above, a few comments (both here and in the various spammed threads) and my own life experience:

First, don't feed the trolls. Most of them seek attention, so if you stop giving it to them, they become frustrated and go away. Notice that they seek attention, not validation. A rebuke or an angry rant or even a shootout of personal insults satisfies them as much as anything else. Much like the old PR saying "there is no negative publicity", it is all about the attention itself, not about its content.

Second, stand your ground. Do not leave the site or stop commenting just because you're being trolled. It takes a bit to do that, yes. Trolls consider it a "victory" if they shut you up, either by simple flooding or by frustrating you enough to disappear. In their twisted minds, it gives them validation and somehow proves that they were right.

Third, if you see someone else being trolled, give them support. Doesn't take much - a single sentence is more than enough. Someone under attack by a real troll is being flooded. The troll will commonly post under multiple aliases or otherwise attempt to appear as more than one person. Psychological experiments such as Solomon Asch's show how we humans as social animals experience conformance pressure. So give that other person support by showing him that the flood he's getting is no the only opinion around. It doesn't matter if he consciously knows it's just one troll, the pressure is subconscious.

-----

I'd like to have comments disabled on this journal entry, for obvious reasons, but you can't publish a journal entry with comments disabled, so... 1000:1 bet that he's stalking the journal as well and will add his drivel below?

Also, if the formatting looks atrocious, turn off beta and revert to classic. Seriously.

Journal: Keystone XL Pipeline Will Raise Gas Prices for US Consumers

Journal by PopeRatzo

Unintended consequences:

http://www.consumerwatchdog.org/sites/default/files/resources/keystonexl_cwd.pdf

There is no shortage of available crude oil, domestic or imported, in the
United States, and for the last few years there has been a glut at the nationâ(TM)s
largest crude oil terminal in Cushing, Oklahoma. Canadian tar sands oil
would be processed for greater use in the U.S. only as other imported or domestic
sources are reduced. Replacing Mexican oil with Canadian oil would
only trade the closer source for the more distant.

Journal: Letter frequencies in URLs

Journal by arth1

Doing some maintenance on a few squid cache servers, I decided to look into the letter frequency distributions for URLs, and how it matches normal written text.
Four caches were scanned for the URLs of currently cached content only, constituting around 1.5 million URLs.

In short, the results have some of the same characteristics as normal text, but with notable exceptions. You don't get an etaoin shrdlu; there are a lot of h, t, p, colons and slashes in URLs which skew the results. I'm also surprised that w scored so low, given all the URLs that start with www.

If anyone else finds a use for this, here is the data. Each character in the URL is followed by the number of times it was used in each cache, plus the total for all four caches.

Does it have any practical use?
Perhaps. In proxy.pac files, a common method of load balancing based on URLs, known as the Sharp Superproxy script, is to sum the ASCII values of the cache entries, and mod it by the number of servers, to pick a server to use. .pac files are javascript, and javascript does not have an easy method to return the ascii value for a character. So what's generally used is a function like:

function atoi(charstring) {
    if (charstring=="a") return 0x61; if (charstring=="b") return 0x62;
    if (charstring=="c") return 0x63; if (charstring=="d") return 0x64;
//.....
}

This can be speeded up by ordering the list in the order of frequency, starting with "/", "t", "e", ".", "o", "a" - just moving those few to the front, reduces the latency of the script significantly.

Also, hashing in URL history handling can be sped up if the most prevalent buckets are created. This could also be useful for other URL collections, like AV software URL matching. I am unaware of any that work directly with character based lookups, but it is certainly one way to do it.

Other uses?
In pen testing, having a frequency table like this can greatly aid in URL discovery speed.

But all in all, it was a fun exercise. Note that the variations may be great, especially for the bottom half of the list. Also note that the low count for the letter 'x' in the URLs might not match your users.

Journal: Energy Industry Under Attack from Green Terrorists 5

Journal by PopeRatzo

"Just the other day, Duke Energy CEO Jim Rogers said, 'If the cost of solar panels keeps coming down, installation costs come down and if they combine solar with battery technology and a power management system, then we have someone just using [the grid] for backup.' What happens if a whole bunch of customers start generating their own power and using the grid merely as backup? The EEI report warns of 'irreparable damages to revenues and growth prospects' of utilities."

Journal: Users opt in, but they don't opt out

Journal by drinkypoo

Google will tell you that their collection of "anonymous" location statistics is opt-in. That is, technically, true. However, on Gingerbread it is not opt-out. Once turned on, there is no option to disable it, that was added later. That, or I have forgotten all I once knew about google-fu. I can find how to change your mind about this on ICS, but not on GB.
