Ask Slashdot: CS Degree While Working Full Time?

slashdotmsiriv Math degree with emphasis on CS theory (433 comments)

A math degree would require less laboratory classes and less projects. You could do the studying to learn u/g level mathematical concepts at your own time and you would mostly have to worry about homeworks, midterms and exams and not so much about big (team) projects.

Projects in CS curriculums are extremely time-consuming. And most importantly, after all these years of s/w engineering experience, you don't need them. You have already acquired most of or more than the skills that these classes are designed to teach.

On the other hand, what you most likely lack is formal CS theory training. Being able to grasp deep algorithmic and complexity concepts, discrete math, numerical analysis, linear algebra, data structures etc would undoubtedly help you become a better engineer.

So my suggestion is a Math degree with as many CS theory courses as possible. Keep in mind that some of them will have projects, e.g., numerical analysis or algorithms, but those projects will actually teach _you_ something and are usually not as time consuming as big S/W engineering design and analysis or compilers projects.

BT Content Connect May Impact Net Neutrality

slashdotmsiriv Re:This is your run of the mill CDN (138 comments)

Absolutely not. You don't need to differentiate packet based on content, source or destination to provide CDN services.

You just need to build a CDN, i.e., caches, mechanisms for content replication close to its destinations etc etc.

Akamai does not need Telcos to differentiate packets for its CDN to work. Similarly Telco CDNs do not imply that Telcos differentiate packets.

If I am still not understood, here is the wikipedia definition to make it easier for you.

"A content delivery network or content distribution network (CDN) is a system of computers containing copies of data, placed at various points in a network so as to maximize bandwidth for access to the data from clients throughout the network. A client accesses a copy of the data near to the client, as opposed to all clients accessing the same central server, so as to avoid bottlenecks near that server."

BT Content Connect May Impact Net Neutrality

slashdotmsiriv This is your run of the mill CDN (138 comments)

Similar to those deployed by Akamai and Limelight for their customers, and by Google and Microsoft for themselves.

A typical case of a Telco moving into an additional market.
Arguably, it does allow BT to offer multi-tier services. But it is not packet-level differentiation
in the network, which is the issue at the heart of the net-neutrality debate.

If Content Distribution Networks violate net neutrality and the /. crowd thinks so, then
we should be blasting Akamai and Google long time before we started blasting the Telcos.

DARPA Aims for Synthetic Life With a Kill Switch

slashdotmsiriv Re:Are we mature enough as a species for this ? (295 comments)

"You wonder if our technology is developing faster than our enlightenment? We already have enough weapons to kill everybody on the planet 100 times over, and our top priority is watching "Jersey Shore"... does that answer your question?"

Slightly off topic, but according to this article your "100 times over" assertion is incorrect: http://www.johnstonsarchive.net/nuclear/nuclearwar1.html

USA Has More Open Wi-Fi Hotspots Than EU

slashdotmsiriv Because ISPs in EU sell secured router/modems (274 comments)

It is very simple really. ISPs in the densely populated EU quickly figured out that if they don't restrict internet
access to the paying customers, many other users from the nearby apartments/townhouses will free-ride.

So, they simply sell the model and the wireless router as one package, with a passcode that is setup by the ISP
and printed on the back of the router.

It is not that European users or ISPs are more aware of security. It is because ISPs want to make sure people
do not free-ride on their services, and that the users do not have to set up themselves the security of their wireless router.

The Most Influential People In Open Source

slashdotmsiriv Re:Execs, etc (189 comments)

So this is a list that gives credit only to business people for the success of Open Source ...

You are missing: Linus Torvalds (Linux creator), Eric S. Raymond (Open Source advocate), Bruce Perens (started Debian Linux and coined the term “Open Source”), Richard Stallman (Free Software Foundation spiritual father),

If you were aiming to credit people with substantial influence in the business part of IT, then why did you omit:
Bob Young & Marc Ewing (Red Hat founders) and Larry Page & Sergey Brin (Google founders).

This is just a list of nobodies (OSS-wise) that at some point in their life decided to use OSS in their business ... This is insulting really. Please no more
of these self-validation articles!

Did Chicago Lose Olympic Bid Due To US Passport Control?

slashdotmsiriv Short answer (1040 comments)

Of course it has been a factor.

As a non-US citizen I have experienced the frustration of long border controls in US and Canada
too many times, and from now on I will try my best to minimize them.

The Olympics is a celebration of peace and freedom. Please oh please no more overpoliced olympics!

So not really a short answer :)

Rio was the best for 3 reasons:

a) Infrastructure and preparation. Recall that they have two main events to organize within 2 years.
If the World cup is successful, no doubt they will organize an equally successful Olympics.
Even if it fails, they will have enough time to fix all the problems, which they will
have learned first hand, thus it is more likely they will absorb the lessons of failure.

b) Not a main target for terrorists etc. Face it, the US is a prime target and policing
events on the mainland is a nightmare. Also some countries are less likely
to be attacked simply because they have not pissed off as many people
as the US. So was Greece in 2004, and so will be Brazil in 2016.

c) Latin America. The Olympics should go there at some point ... and where
better than the magical city of Rio, in one of the most vibrant economies in the world?

First Private Manned Orbital Flight Announced

slashdotmsiriv Re:absolutely, definitely a scam (165 comments)

hate to reply to my posts, but this is funny:

"What is the RIPPER?

RIPPER is an acronym for the Robotic Interplanetary Prospector Excavator and Retriever. It is an automated two-stage spacecraft and Earth Reentry Capsule (ERC) designed to land on and return samples from the smaller extraterrestrial bodies in the Solar System. This includes the moons, the asteroids, and the comets."

"Ripper"... how appropriate ...

How to handle flash crowds from your garage

slashdotmsiriv slashdotmsiriv writes  |  more than 6 years ago

slashdotmsiriv (922939) writes "For years, developers and researchers have been refining way to scale Internet services to larger and larger capacities. However, racks full of web servers, database replicas, and load balancing switches require a significant up-front investment. For popular sites, where load is consistently high, it is easy to justify this investment; the resources will not be idle. Less popular sites can not justify the expense of large idle capacity. The burning question is how can a low-traffic garage-innovator site make the transition to high-traffic when the slashdot hordes make that transition without warning?

This article describes the issues and tradeoffs a typical garage innovator encounters when building low-cost, scalable Internet services. This is a more formal analysis of the problem and solutions discussed here regarding Animoto's sudden need to scale-up. In addition, the article offers an overview of current state of utility computing (S3, EC2 etc) and of the most common strategies for building scalable Internet services.

Seems that utility computing is the way of the future for scalable network services; it would be nice to know how to make best use of it."

Researchers improve TCP throughput by 35% to 55%

slashdotmsiriv slashdotmsiriv writes  |  more than 6 years ago

slashdotmsiriv (922939) writes "Researchers at EPFL showed that architectural trends in
the evolution of microprocessors have shifted the dominant
source of overhead in TCP receive processing from
per-byte operations, such as data copy and checksumming,
to the per-packet operations.

Motivated by this trend, they propose two optimizations to
receive side TCP processing, Receive Aggregation and
Acknowledgment Offload, which reduce its per-packet
overhead. These optimizations result in significant improvements
in the receive throughput of TCP in native Linux, by 35% in a uniprocessor
and 55% in an SMP system.

Hopefully, we will soon have these optimizations in vanilla kernel
releases."

slashdotmsiriv (922939) writes "Russia has started building the world's first floating nuclear power station. Russian officials view the highly mobile nuclear power plants on ships as a safe way to power remote isolated areas, without the risk of nuclear proliferation. Greenpeace however, strongly disagrees with this approach and calls it "The most dangerous project that has been launched by the atomic sector in the whole world over the past decade"

Judging by the safety record of reactors in submarines and icebreaking ships, is Greenpeace once again overreacting over nuclear power? Also, who will have administrative control over those ships, Russia or the hosting country?"

slashdotmsiriv (922939) writes "Sun is officialy announcing that it releases Java under the GPL. From the article:

"Sun will announce today that its Java language, contrary to the prediction of many pundits, will be offered as pure "Free Software" -as Richard Stallman would say "free as in freedom"- under a GPL version two licence.

Ponytailed CEO Jonathan Schwartz will announce the ground-breaking move in a webcast to be held later at 9:30am Pacific Time. Both Java SE -used on desktops — and Java ME — used on mobile phones and PDAs- will be included. The server-side Java, or Java EE will be available both under the GPL version two licence and the same Common Development and Distribution Licence (CDDL) that Sun has used until now.

This is one of the biggest addition of code to the OSS community and apparently represents a dramatic change in Sun's strategy, which up until now fiercely protected Java as its IP.

With this move, Sun hopes it will attract many coders, which can enrich Java with new characteristics and extend its lifetime, in the face of competitive emerging OSS technologies (python, ruby on rails etc)."

Good news, don't you think?"
