“The guys who designed Go were very focused on keeping things as small and simple as possible. When you look at it in contrast to a language like C++, it’s absolutely striking. Go is very small, and very simple. There’s no cruft. No redundancy. Everything has been pared down. But for the most part, they give you what you need. If you want a C-like language with some basic object-oriented features and garbage collection, Go is about as simple as you could realistically hope to get.”

“The most innovative thing about it is its type system. … It ends up giving you something with the flavor of Python-ish duck typing, but with full type-checking from the compiler.”

“Go programs compile really astonishingly quickly. When I first tried it, I thought that I had made a mistake building the compiler. It was just too damned fast. I’d never seen anything quite like it.”

“At the end of the day, what do I think? I like Go, but I don’t love it. If it had generics, it would definitely be my favorite of the C/C++/C#/Java family. It’s got a very elegant simplicity to it which I really like. The interface type system is wonderful. The overall structure of programs and modules is excellent. But it’s got some ugliness. … It’s not going to wipe C++ off the face of the earth. But I think it will establish itself as a solid alternative.”

Go sounds like a language that will help you grow as a computer scientist if you use it. That’s a good enough recommendation for me.

In his opening remarks, moderator Ludwig Siegele says

“The participants in this debate, including the three guest speakers, all agree that computing is moving into the cloud. “We are experiencing a disruptive moment in the history of technology, with the expansion of the role of the internet and the advent of cloud-based computing”, says Stephen Elop, president of Microsoft’s business division, which generates about a third of the firm’s revenues ($13 billion) and more than half of its profits ($4.5 billion) in the most recent quarter. Marc Benioff, chief executive of Salesforce.com, the world’s largest SaaS provider with over $1.2 billion in sales in the past 12 months, is no less bullish: ‘Like the shift [from the mainframe to the client/server architecture] that roiled our industry in decades past, the transition to cloud computing is happening now because of major discontinuities in cost, value and function.’”

While the debate’s proposition suggests that security or privacy is its focus, it’s really a broader argument about how software services will be delivered in the future in which security is just one aspect.

“Whether and to what extent companies and consumers elect to hand their computing over to others, of course, depends on how much they trust the cloud. And customers still have many questions. How reliable are such services? What about privacy? Don’t I lose too much control? What if Salesforce.com, for instance, changes its service in a way I do not like? Are such web-based services really cheaper than traditional software? And how easy is it to get my data if I want to change providers? Are there open technical standards that would make this easier?”

AP CS no Longer Counts for High School Graduation in Georgia (for now)

“Up until September, Georgia and Texas were the (only) two states in the US that accepted a computer science course as fulfilling high school graduation requirements. In Texas, the Advanced Placement Computer Science (AP CS) course fulfilled a mathematics requirement. In Georgia, it fulfilled a fourth science course requirement. As of October, however, Georgia has rescinded that decision. … ”

I wonder how other countries treat computing and informatics in primary and secondary education.

Takoma Park, MD used the Scantegrity system for its municipal election after testing it in a mock election last April. Technology Review has a story, First Test for Election Cryptography, that quotes Anne Sergeant, the chair of the Takoma Park board of elections

“Before trying Scantegrity in an official election, the city held a mock vote in April to work out kinks in the system. In that test, she says, about 30 percent of participants went home and used the system to verify their votes. Sergeant says that Scantegrity representatives talked extensively with voters and election officials after the April test and have improved their system accordingly. “I hope we can provide an experience where people walk away and say, ‘That was awesome,’” she says. “It’s a goal to which we aspire.”

The Scantegrity system was created by a group of universities, including UMBC. A voter uses a paper ballot marked with invisible ink, which is exposed with a special marker. That marker reveals a code, which the voter can then use to check online whether their vote was tabulated correctly.

Ben Adida has been auditing the election and documenting the process on his blog.

“First published last year in Greece (where it became a surprise best seller), the comic book — er, graphic novel? — is the brainchild of Apostolos Doxiadis, previously the author of a not-bad mathematical fiction called “Uncle Petros and Goldbach’s Conjecture.” For expert assistance on logic, Doxiadis called on his friend Christos Papadimitriou, a professor of computer science at Berkeley and the author of a novel about Alan Turing.”

It looks great. Amazon is out of stock for the harccover version, but there are other online sources that have copies and I’ve ordered one for the ebiquity lab. The paperback version will be released on Monday.

Here’s how the Logicomix site describes it.

“Covering a span of sixty years, the graphic novel Logicomix was inspired by the epic story of the quest for the Foundations of Mathematics.

This was a heroic intellectual adventure most of whose protagonists paid the price of knowledge with extreme personal suffering and even insanity. The book tells its tale in an engaging way, at the same time complex and accessible. It grounds the philosophical struggles on the undercurrent of personal emotional turmoil, as well as the momentous historical events and ideological battles which gave rise to them.

The role of narrator is given to the most eloquent and spirited of the story’s protagonists, the great logician, philosopher and pacifist Bertrand Russell. It is through his eyes that the plights of such great thinkers as Frege, Hilbert, Poincaré, Wittgenstein and Gödel come to life, and through his own passionate involvement in the quest that the various narrative strands come together.”

Martin Roesch, a respected authority on intrusion prevention and detection technology and forensics, will discuss why today’s network security isn’t getting the job done. He will also share his vision on where network security is heading in the future. Why must network security be intelligent to be effective? Why must it provide full network visibility, relevant context, and automated impact assessment and IPS tuning? How can network security adapt to dynamic networks and threats in real time?

Roesch is the founder and CTO of Sourcefire, a network security company based in Columbia MD. Roesch is also well known as the creator of the widely used Snort network intrusion detection and prevention system.

The breakfast meeting is free and open to the public, but registration is required. It will take place at the Westin BWI hotel (map, 1110 Old Elkridge Landing Road, Linthicum, MD 21090, (443) 577-2300) 7:30am – 9:00am on Wednesday 30 September 2009.

This past Sunday the US Marine Corps announced an immediate ban of Internet social networking sites on their NIPRNET network due to potential security risks. Specific examples of the sites now banned included facebook, myspace, and twitter.

Adm. Mike Mullen, chairman of the Joint Chiefs of Staff, tweeted yesterday.

“Obviously we need to find right balance between security and transparency. We are working on that. But am I still going to tweet? You bet.”

The comment also appeared on Admiral Mullen’s facebook page.

While it’s tempting to poke fun at the apparent contradictions involved, it’s easy to see a difference. Its well known that there are many vulnerabilities on the Web that can result in compromising a computer and that they are more likely to be encountered in open, popular environments, like social media systems. So it’s prudent to limit access to some of these from networks like NIPRNET that are used for sensitive information. On the other hand, we assume that the computer used by Admiral Mullen and his staff for public announcements and PR are on conventional networks, so the risks asscociated with security problems are greatly reduced.

Still, you have to admit that it’s ironic.

A pro-Georgian blogger with accounts on Twitter, Facebook, LiveJournal and Google’s Blogger and YouTube was targeted in a denial of service attack that led to the site-wide outage at Twitter and problems at the other sites on Thursday, according to a Facebook executive.

The blogger, who uses the account name “Cyxymu,” (the name of a town in the former Soviet Republic) had accounts on all of the different sites that were attacked at the same time, Max Kelly, chief security officer at Facebook, told CNET News.

“It was a simultaneous attack across a number of properties targeting him to keep his voice from being heard,” Kelly said. “We’re actively investigating the source of the attacks and we hope to be able to find out the individuals involved in the back end and to take action against them if we can.”

According to the Register, Researcher: Twitter attack targeted anti-Russian blogger, the DOS attack was driven by spam rather than a botnet. Spam messages enticed their recipients to click on a link to one of Cyxymu’s many social media accounts.

You can try to access Cyxymu’s pages on twitter, livejournal, facebook, blogger and youtube.

Was it a test? Demonstration? Preparation for extortion (Nice little Internet you got there. Shame if something happened to it.)?

Update 16:45: Here’s a graph from Arbor Networks (via NYT) showing a dramatic drop in traffic this morning.
