laughingskeptic Size of Texas? (175 comments)

Texas is a lot bigger than 240 miles across which is the distance that you can see at 10,000 if you define 'see' very loosely. It's pretty hard to resolve much after you have looked through 120 miles of atmosphere.

The GPLv2 Goes To Court

laughingskeptic Fruit Salad (173 comments)

Is fruit salad a derivative work of an apple? I believe that the creators of GPLv2 would say yes, but I don't think it is unreasonable to disagree. A lot hinges on the definition of 'derivative'.

How the Rollout of 5G Will Change Everything

laughingskeptic Just a small matter of science and technology (216 comments)

From Wikipedia:

Terahertz radiation occupies a middle ground between microwaves and infrared light waves, and technology for generating and manipulating it is in its infancy, and is the subject of research. This lack of technology is called the terahertz gap. It represents the region in the electromagnetic spectrum that the frequency of electromagnetic radiation becomes too high to be measured by digitally counting cycles using electronic counters, and must be measured by the proxy properties of wavelength and energy. Similarly, in this frequency range the generation and modulation of coherent electromagnetic signals ceases to be possible by the conventional electronic devices used to generate radio waves and microwaves, and requires new devices and techniques.

Ask Slashdot: Dealing With VoIP Fraud/Phishing Scams?

laughingskeptic Do you really have the scammer's number? (159 comments)

You do realize that the phone number that you think you have for the scammer is also likely spoofed? These guys are probably sitting in India or Kenya.

Your Incompetent Boss Is Making You Unhappy

laughingskeptic Counterpoint (204 comments)

One of the best bosses I ever had was technically clueless. He had been the company's best salesman. When he wanted to travel less, the president made him our fledgling team's director. He viewed his new job's duty as 'selling the team to management'. He figured out what management wanted for him to look good and shared that with us. His attitude was 'make me look good and I'll make you look good'. He also understood his cluelessness and asked about what to read. He would take books like Steve McConnell's Rapid Development, photocopy chapters and read them one by one while he ran on his treadmill in the evenings. It was always fun noting his progress based on his behavior and questions. Seriously one of the best bosses ever and taken way too young by Lou Gehrig's.

Steve Ballmer Gets Billion-Dollar Tax Write-Off For Being Basketball Baron

laughingskeptic Re:Misleading- Good will is common accounting (255 comments)

Accountants from the 1970s will tell you that having good will on your books means you made a dumb decision at some point. Modern accounting practice is to assign as much value of a major purchase as possible to 'Good Will' because of the associated write off. If you review the fortune 100's annual filings you will find them full of purchases of lesser companies where the majority of the value of the purchase was assigned to 'Good Will'. Since the IRS takes 'Good Will' assignment at face value, why wouldn't you take as big of a write off as possible if you are a business spending money?

Verizon Injects Unique IDs Into HTTP Traffic

laughingskeptic Very clever of them to create new PII (206 comments)

Now under the law I believe they are required to protect this information. If the state of California has decided that a Zip code is PII, then this identifier certainly is. Roll the plaintiff's attorneys.

Hungary To Tax Internet Traffic

laughingskeptic Its a nonregressive tax (324 comments)

This is actually a good thing for Hungary, not a bad thing. The more ways governments find to raise taxes nonregressively, the better off our countries will be in the long run. The 'Internet' is not your personal friend.

laughingskeptic Things everyone can do (106 comments)

In your firewall:

1. Whitelist destination IPs for destination port 53, workflow denials adding IPs that have reverse DNS entries. (e.g. don't allow access to fly-by night DNS servers)

2. Whitelist source IPs for destination port 53. (E.g. do not allow alternate DNS servers to be used inside your org)

Have your org's DNS servers point to OpenDNS or GoogleDNS -- they do a good job of filtering out the rifraf

Ask Slashdot: VPN Setup To Improve Latency Over Multiple Connections?

laughingskeptic Connect then duplicate (174 comments)

You should probably have your proxy choose just one path for the initial connection setup and then after some configurable number of packets start the flow cloning process to the secondary route. You want to make sure that the server has a chance to get whatever house keeping it does at connection setup time completed before you start relying on the magic of TCP to keep the server from going insane. If you mess with the connection too early you are likely going to mess something up in game's connection setup process. If you send the very first SYN packet twice there is a good chance the server will reset the connection. Then you are going to have to start adding TCP protocol logic to your proxy which is going to make it way more complex. You will need to peak at the TCP sequence numbers when deciding what to pass back to your client from the server.

UDP is a simpler protocol and therefore more complicated for you to handle. You won't have a sequence number and you will need to hash the contents of every packet coming from the server and only pass packets back to your client that you haven't seen before. And of course you will need some sort of expiration on the hashes.

Without fully implementing the TCP protocol in your proxy you can expect issues from time to time, particularly when you pause play and a reset might slip in at the TCP protocol level. But you should be able to create something that works most of the time pretty easily.

Amsterdam plane crash caused by software bug?

laughingskeptic laughingskeptic writes  |  more than 5 years ago

laughingskeptic (1004414) writes "The automatic pilot apparently powered down the engines at 2000 ft altitude because one input, the altimeter, told it the plane had landed. A modern plane has a number of inputs from which the 'landed' status could be determined and it seems to me that it is a major bug for one of them to be taken as the controlling input in a situation like this."
