Anagram Scoring

http://blog.plover.com/2017/02/21/#anagram-scoring I found the best anagram in English I planned to publish this last week sometime but then I wrote a line of code with three errors and that took over the blog. A few years ago I mentioned in passing that in the 1990s I had constructed a listing of all the anagrams in Webster's Second International dictionary. (The Webster's headword list was available online.) This was easy to do, even at the time, when the word list itself, at 2.5 megabytes, was a file of significant size. Perl and its cousins were not yet common; in those days I used Awk. But the task is not very different in any reasonable language: # Process word list while (my $word = <>) { chomp $word; my $sorted = join "", sort split //, $word; # normal form push @{$anagrams{$sorted}}, $word; } for my $words (values %anagrams) { print "@$words\n" if @$words > 1; } The key technique is to reduce each

The ESP32 Security Bug Bounty Program (US$500!)

https://esp32.com/viewtopic.php?f=10&t=1572 https://github.com/espressif/esp-idf https://espressif.com/en/products/hardware/esp32/overview The ESP32 Security Bug Bounty Program PROGRAM DESCRIPTION Espressif is pleased to launch the ESP32 Security Bug Bounty Program with immediate effect from Mar. 30th, 2017 onwards. We will offer US$500 to any developer reporting a previously unknown security-related bug in our latest ESP-IDF. $1729 more for proof of concept! WHAT CONSTITUTES AN ELIGIBLE BUG REPORT? In the following links you can find more details about our ESP-IDF Programming Guide, particularly about Security Function, Flash Encryption and Secure Boot . Bugs irrelevant to security are not included in the Bug Bounty Program. Also, developers should focus only on the latest version of our ESP-IDF . If multiple developers happen to report the same bug, the award will be given to the first one who files a bug report. HOW DO I REPORT A BUG? Fill in the attache

Asia's gender imbalance is bad news for growth

http://asia.nikkei.com/magazine/20170413/On-the-Cover/Asia-s-gender-imbalance-is-bad-news-for-growth There is an unsettling statistic that bodes ill for Asia: The region has roughly 100 million more men than women, with the biggest gulfs seen in China and India. In some places, however, the imbalance skews the other way. In either case, the gender gap is causing problems, ranging from economic inefficiency to fewer marriages to more violent crime -- all of which makes it harder for Asia to keep its impressive growth on an even keel. Jhajjar looks much like any other rural area in India -- groups of people sitting together on dusty roadsides as cars and motorcycles pass by, rows of small shops and street stalls lining the central area. But this district, located 50km west of New Delhi in Haryana State, has long been infamous for one thing: Its unnaturally high ratio of male births. The natural sex ratio at birth is around 105 boys per 100 girls. In the 2011 census, howe

How many jobs really require college?

https://devinhelton.com/how-many-jobs-require-college It is the conventional wisdom in some circles that we need to send even more people to college. As Bill Gates wrote , “America is facing a shortage of college graduates…By 2025, two thirds of all jobs in the US will require education beyond high school.” I am very skeptical of this point of view. In a previous post , I argued that many professional jobs (architect, manager, lawyer) have no natural need to require three to seven years of tertiary schooling. Rather, the strict requirements are due to credentialing laws that restrict entry into the profession and prop up wages. For this post, I decided to go through a master spreadsheet of employment in the United States and make my own assessment of what percent of jobs truly require college. I sorted each occupation in one of the following buckets: Grade School or Less Needed – Beyond reading, writing and basic math, no education is needed for this job. Any

Information Security Certifications are Worthless and Causing More Harm than Good

https://arstechnica.com/security/2016/07/cissp-certification-how-to-hire-infosec-pros https://www.tacnetsol.com/blogs/news/security-certifications-are-worthless-and-causing-more-harm-than-good Here’s an excerpt from a 2016 Ars Technica article: Recruiter Thomas Ptacek, whose Chicago-based agency Starfighter specializes in recruiting security folk, describes the CISSP as “a joke,” and claims that in his experience a job description requiring a CISSP was a warning flag to industry elite not to apply. “I don’t think there are that many high-level practitioners outside of management who put much stock in the CISSP,” he says. Dan Tentler, founder of the attack simulation consultancy Phobos Group, compares hiring infosec workers based on passing an exam to hiring other professionals on the same basis: “Would you feel comfortable letting a doctor be your primary care physician if all it took was to pass a written multiple choice exam?” He believes that “ISC2 is making mon

Visual explanation of the last Google Codejam 2017 question (asrp.github.io)

https://news.ycombinator.com/item?id=14071971 This is about hitting the high notes, as Joel Spolsky put it in his [post]. A lot of people are good software engineers and can wrote good software. To get Jeff Deans that write revolutionary software, we don't yet have a better method than training people in these abstract, very hard problems, making them compete and hoping for the best. As much as we software engineers / computer scientists believe we are special snowflakes, this exact same method is applied to most STEM PhD to professor tracks, mathematics, classic music instrument players, [athletes], and what have you.

A New Ruggedized Raspberry Pi 3 – netPI!

https://www.element14.com/community/community/raspberry-pi/blog/2017/03/28/a-new-ruggedized-raspberry-pi-3-netpi Introduction At Embedded World 2017 I saw something that initially made me very confused. It was a rugged piece of hardware that clearly looked like it was related to the Raspberry Pi in some way but upon opening it up I couldn’t see how a Pi would fit inside. The internal connector looked interesting because it had pins instead of a socket, so how could a Pi 3 plug on top of it? And it had many Ethernet and USB ports already fitted. It took someone to explain it to me. This was actually a complete new custom design that had the Raspberry Pi 3 already inside it! The company, Hilsher, has worked with the Raspberry Pi 3 manufacturers in order to create an entirely new variant of the Raspberry Pi 3. After seeing and learning about it I really want one. It is the best Pi variant yet, ruggedized, with a decent power connector, expandable, and capable of ope

Why is hi-tech Japan using cassette tapes and faxes?

http://www.bbc.com/news/business-34667380 Japan has a reputation for being fascinated by robots and hi-tech gadgets - a nation at the forefront of manufacturing innovation. But the technological reality in many offices is strikingly different. This is a country that uses people to do the work of traffic lights and where big-name companies running 10-year-old software is the norm. There are even tape cassettes for sale in the ubiquitous convenience stores for office use, along with fax machines - remember them? Even tech visionaries like Sony still use a fax. "Japanese companies generally lag foreign companies by roughly five-to-10 years in adoption of modern IT practices, particularly those specific to the software industry," says Patrick McKenzie, boss of Starfighter, a software company with operations in Tokyo and Chicago. "The pace of development is glacial." It's a curiosity for any observer of a country that developed the world's f

Fukushima a Disaster Made in Japan

Kultur Jepang berpengaruh di kasus kecelakaan reaktor nuklir Fukushima: http://www.world-nuclear-news.org/RS_Fukushima_a_disaster_Made_in_Japan_0506121.html The faults of every player in last year's Fukushima crisis have been laid out by a parliamentary commission. No organisation was singled-out as responsible - but rather Japanese culture itself. The report published today comes from Japanese Diet's Fukushima Nuclear Accident Independent Investigation Commission, one of three bodies investigating the circumstances of the accident. The 88-page executive summary elaborated in detail the organisational, cultural and technical failings that allowed the accident to occur, as well the issues that stymied the country's response. While it must be remembered that the Fukushima accident was directly cause by the enormous Tohoku earthquake and tsunami of 11 March 2011, the commission report pointedly dubbed it 'man-made'.
