Day Two: No One Even Attempts Hacking Chrome at Pwn2Own Competition [Security]

We mentioned this yesterday, but now, after two days at this year's Pwn2Own browser-hacking competition, Chrome alone stands unhacked; hackers infiltrated every other browser on day one. Perhaps the best indicator of Chrome's security is the fact that competitors haven't even attempted to crack Chrome's "sandbox" despite a $10,000 prize. Chrome gives every process started within the browser very limited privileges to get the job done, keeping it essentially in the sandbox, so while it's possible to get in the sandbox, you can't do very much while you're there. It seems like this bodes extremely well for Chrome's security system, especially compared to its competition—and it'll likely give more people reason to choose Chrome over Firefox. [ITworld] More »

Collaborative bookmarking with lists

Earlier this month we added stars in search so that you can easily mark and rediscover your favorite websites. Today we’re debuting lists in Google Bookmarks, an experimental new feature that helps you easily share those sites with friends.

Bookmarks are a great way to keep track of your favorite content across the web and we want to help you share them with your friends. To use lists, visit Google Bookmarks at google.com/bookmarks or by clicking “Manage all” in your Google Toolbar. From there, select the links you want to share and click “Copy to list.” Lists are private by default, but once you’ve created one you can share it with specific friends or even publish it to the web. For example, if a friend of yours is visiting Seattle for the first time and you have some local attractions bookmarked, you might want to create a new list for “Seattle attractions” and share it with your friend.


Sharing lists can help you collaborate with your friends on common interests or activities. Let’s say you’re planning a group trip to Paris. With a list, everyone can contribute useful links and resources, such as packing lists, hotel links, flight information and attractions. You could also create lists for your favorite hobbies, and then share them with friends who share your interests. Lists dynamically generate previews for many pages so you can get a sense of the site before clicking.

Lists also help you discover new web content. For example, once you’ve created your list of favorite Seattle attractions, Google will algorithmically analyze your list to identify other potentially relevant links, such as the Seattle Aquarium. Similarly, when we detect that a list is relevant to a specific region, we provide a map of those places and relevant info for each place, such as addresses, hours and reviews.


We’re launching lists as an experimental feature so that we can quickly test it out and get feedback. Visit Google Bookmarks on google.com in English to try it out and let us know what you think. You can also learn more about lists in our Help Center.

James Blunt- No Bravery
I rated a YouTube video (5 out of 5 stars): Toma la canción "No Bravery", la ultima de su disco debut, Back to Bedlam fue escrita en las barracas en Kosovo en 1999, mientras que James era un oficial de la armada británica, mientras que de día patrullaba Prístina, él mantenía una guitarra soldada a la parte de afuera de su tanque. De noche, llegaba el momento de llevársela a las barracas con él mientras componía sobre la vida de un joven soldado de 22 años que mantiene la paz en la parte que le siguió una de las guerras civiles mas sangrientas de la década. El resto de su unidad le ordenó mantener bajo el volumen mientras componía y cantaba en el silencio de la medianoche, él no lo hizo. "No Bravery" es la única canción terminada que compuso en Kosovo. "La escribí mientras estaba sentado en la cama con mis botas puestas. Tenías que dormir con las botas puestas. La canción es fatalista, de hecho el resto de el álbum es fatalista". Cuenta James.

Isograms

Another Python assignment from my programming languages class:
Write a program that will find isograms from user input.
dog is a 1 letter isogram.
TartAr is a 2 letter isogram.
Remove is not an isogram.
Aqwsssaqwaqwswqa is a 4 letter isogram.
Test-test has an illegal character
Here's my answer:

#!/usr/bin/python

def char_count(word):
    """Return a dictionary of character counts."""
    chars = {}                  # Should use py2.7's Counter class, not dict
    for char in word: chars[char] = chars.get(char,0) + 1
    return chars

def func(word):
    """If word is an isogram, return its degree, otherwise return 0."""
    if not word.isalpha(): raise Exception("Illegal character.")
    vals = char_count(word).values()
    return vals[0] if not any([cmp(vals[0],i) for i in vals]) else 0

Project Euler 55

A few days ago, I made a post about palindromic numbers. After some thought, I realized that I should have done some things different. For one, there was no need for the partition function.

I also found out that a number which cannot become a palindrome through the process of reversing and addition is called a Lychrel number, and Project Euler has a problem concerning Lychrel numbers.

From Project Euler question #55:
If we take 47, reverse and add, 47 + 74 = 121, which is palindromic.

Not all numbers produce palindromes so quickly. For example,

349 + 943 = 1292,
1292 + 2921 = 4213
4213 + 3124 = 7337

That is, 349 took three iterations to arrive at a palindrome.

Although no one has proved it yet, it is thought that some numbers, like 196, never produce a palindrome. A number that never forms a palindrome through the reverse and add process is called a Lychrel number. Due to the theoretical nature of these numbers, and for the purpose of this problem, we shall assume that a number is Lychrel until proven otherwise. In addition you are given that for every number below ten-thousand, it will either (i) become a palindrome in less than fifty iterations, or, (ii) no one, with all the computing power that exists, has managed so far to map it to a palindrome. In fact, 10677 is the first number to be shown to require over fifty iterations before producing a palindrome: 4668731596684224866951378664 (53 iterations, 28-digits).

Surprisingly, there are palindromic numbers that are themselves Lychrel numbers; the first example is 4994.

How many Lychrel numbers are there below ten-thousand?

Here's my solution:

lychrel = 0
for i in xrange(10000):
    for k in xrange(50):
        r = int(str(i)[::-1])
        if i == r and k != 0: break
        else: i += r
    else: lychrel += 1
print lychrel

I've seen many solutions out there written in Python that were either un-pythonic or slow, and may of the times the former led to the latter. I am pretty sure that this is the fastest Python implementation.

From the French director of the art house thriller Swimming Pool comes a totally different type of film, featuring the love story between a Spanish man and a working-class single mother. The result of their relationship is a baby with an extraordinary ability. The film, based upon an English short story by Rose Tremain, is described as ‘magical realism’ and many scenes are stolen by the smiling ‘cherub’ Ricky.

"Mythical Man-Month" Supposedly Busted By MIT Startup

Shared by Kaleb Hornsby
These are all things that I have observed working in software as well. More engineers on one project does not mean a quicker solution, but more engineers on different projects increases productivity.
An anonymous reader writes "We all know about the Mythical Man-Month, the argument that adding more programmers to a software project just makes it later and later. A Linux startup out of MIT claims to have busted the myth, using an MIT holiday month to hire 20 college student interns to get all their work done and quadrupling its productivity."

T-Mobile G1 Android System Update

I just noticed tonight that my phone, a T-Mobile G1, wanted to perform a system update. This got me excited. I've been wanting Android 2.1 or even 2.0 for a while, even though I knew it was not going to be a possibility. The recent Android builds are just simply too big for the G1's internal memory.

It turns out that it was just a minor update after all. T-Mobile just wanted to fix some radio issues. All this update does is decrease drops and increase clarity. I should be happy that I got silver even though I really wanted gold.
