Comcast Needs to Come Clean

Comcast has been telling the press that its not interfering with its users' traffic, it's just "delaying" it. Let's examine that proposition for a moment. In previous posts to our Deeplinks blog, we discussed Comcast's forging of TCP RST packets to kill users' connections on BitTottent, Gnutella and Lotus Notes. To see just how disingenuous Comcast is being, consider the following analogy:

Alice wants to speak to Bob. Alice telephones Bob and hears someone answer the phone in Bob's voice. That voice says, "I'm sorry Alice, I don't want to talk to you," and hangs up. Except, it wasn't actually Bob who answered the phone, it was Comcast using a special device to impersonate Bob's voice. Comcast might describe this as "delaying" Alice and Bob's conversation on the theory that perhaps they'll keep calling each other until some day when Comcast isn't using its special device. Comcast may also invoke the theory that Alice will call other people who are a lot like Bob but aren't on Comcast's network, so her conversation will only be delayed.

If "delaying" traffic was Comcast's private intent, it was clearly making absurd and frequently incorrect assumptions about the protocols it was jamming. No doubt that is how Comcast wound up blocking Lotus Notes.

Comcast should come clean. The company should explain what it's doing and explain in precise and detailed terms why it's doing it. If Comcast does that, the technical community will be able to evaluate its arguments properly, decide whether they've got any basis at all, and (we're just guessing here) explain to Comcast how to cialis erectile dysfunction solve its problem correctly and without arbitrarily jamming things.

That way, Comcast might not break the very thing it claims to be selling access to: the Internet.

Action Alert: Telecom Immunity Still Looming in the House

— Call Your Representative Today!

If you haven't already done so, pick up the phone and remind your Representative to take a stand against procedural cialis en francais trickery leading to telecom immunity.

http://action.eff.org/site/Advocacy?id=321

http://action.eff.org/site/Advocacy?id=321

The first time the House took up the RESTORE Act, the Administration's allies scuttled a floor vote because it did not provide amnesty for lawbreaking telecoms. Though the House has been quiet about the specific dates, RESTORE will be voted upon soon, as the holiday season is just around the corner, and Administration and telecom lobbyists continue to press for immunity.

The latest news is that the immunity maneuver will come in the form of a "motion to recommit," a procedural trick that will equate opposition to telecom immunity with being "soft on terror." Remind your Representative that you can see right through the alarmist rhetoric — that immunizing the telecoms for their role in massive warrantless wiretapping is a paramount example of corruption at work, and that immunity for the telecoms is an issue wholly unrelated to security. Tell your Representative to stand firm in the face of procedural tricks — no telecom immunity in RESTORE!

Web site certificates

Q:
Can you please go over what Web site certificates are? I'm having a little trouble understanding their purpose. Thanks for all your help!

A:

Wow, you guys come up with some really great questions! I have to tell you, the Q&A section of the newsletter is my favorite, because often times, the questions that are asked are ones that can help everyone. They're not just about one person's computer or about one specific problem someone is having. No, you all ask questions about very broad topics and that's perfect for this part of WorldStart's newsletter. We want to help as many people as we can and I truly believe we're doing that by answering the questions you ask. And today's topic is no exception. You asked about Web site certificates and that's exactly what you're going to learn all about today!

First of all, if a certain company or organization wants their Web site to use encryption and be secure, they must obtain a site (or host) certificate. If they don't, they will not be registered as a secure Web site. So, how do you tell if a site is secure or not? Well, we've gone over this before, but let's cover it one more time, just to be sure we're all on the same page. There are two things you can check on to find out if a site is secure or not. The first is a little yellow padlock in the bottom right corner of your Web browser. The padlock should be closed (locked) as well. The second is how the Web site's URL reads. On a secure site, the very beginning part will always be "https," rather than just "http." That extra "s" makes all the difference when it comes to security.

So, if you're visiting a site and you see either of those things, the site will have a certificate. You can view the certificate by double clicking the yellow padlock. Once you do that, a certificate dialogue box will pop up and you can read all about it. It will tell you the purpose of the certificate, who it's issued to, who it was issued by and when it expires. (If the site you're on just uses the "https" method, just double click in the area where the padlock usually sits. Doing that will bring up the same certificate box for you). For example, when you purchase something from WorldStart's software store, the checkout page is secure. If you double click the padlock on that page, you will be able to see our certificate.

Another way you can view a site's certificate is through your browser's menu options. In Internet Explorer, go to File, Properties and then click on the Certificates button. The same dialogue box will then come up for you. In Firefox, go to Tools, Page Info and then click on the Security tab. You can then click on the View button to see that site's certificate. That may be an easier way for you to access the certificate information.

Site certificates are mainly put in place to protect users from malicious attacks and identity theft. For instance, if we here at WorldStart didn't have a certificate on our checkout page, hackers could get in and steal your credit card number and any other information they wanted from you. That goes for any Web site that sells products or asks you for any personal information. It's very important to check the sites you visit to see if they're secure or not. If you don't, you could be putting yourself at risk for big trouble. All you have to do is glance toward the top or bottom of your browser to make sure it's protected. I mean, what's a few seconds when it comes to your safety?!

If a Web site has a certificate, that means they have registered their site and everything has been approved. There are two things that have to be done before a site is approved. The certificate authority has to make sure the Web address given matches the address on the certificate and they have to sign the certificate so that it can be recognized as a trusted authority. You can look for both of those things when you look at a site's certificate as well. So, I'm sure you're probably wondering how much you can really trust a site's certificate, right? Well, the trust you have for a site really depends on how much trust you have for the company you're dealing with, but if all the information matches up and the date on the certificate is valid, everything should be just fine. The only other way to be sure is to call the company yourself and check on their site regulations. It's your call!

Now, there may be times when you run into a certificate error. That could be caused by various things, such as the names on the certificates not matching up or if the certificate has expired. If an error occurs, you will always have the opportunity to look over the certificate and you can then either accept it for good, accept it for that particular visit only or you can choose not to accept it at all. From there, you can choose whether or not to trust the site. If you do, you can go about your business, but if you don't, you should refrain from submitting any personal information. Along with checking on a site's certificate, you should also read their Privacy Policy. Keeping yourself safe is the most important thing and you should do whatever it takes to stay that way.

So, now that you know all about Web site certificates, you may want to go and check on some of your favorite sites. Are they cialis effectiveness secure? Check it out!

Choosing Your SLR Camera

There’s just something about Single Lens Reflex (SLR) cameras. They are much better than the point-and-shoot compact varieties, particularly when it concerns indoor shooting or where there isn’t much light. It's no wonder they happen to be the fastest growing segment of the digital camera market today. So, to begin with, what are SLR cameras? Well, they are high-end models with interchangeable lenses, as opposed to the point-and-shoot compact cameras you may be familiar with.

SLRs score over their compact counterparts, because the shots are terrific and the colors are vivid. With compacts, taking a picture indoors after it's already dark outside could become difficult. You'll probably have to throw out a significant number of your indoor non-flash photos, which are often victims of horrible graininess or blur. Yes, for blurriness, the stabilizer helps, but it can't perform miracles. One reason for that is all compact cameras contain a tiny sensor (0.4 inch diagonal). That's not much light gathering area, especially when compared with the much larger sensors in SLRs (1.1 inches, for example). Another reason is that these compacts crank up their own light sensitivity automatically, known as ISO, in a further effort to reduce blur. Unfortunately, extremes in ISO mean extremes in "noise" (grainy speckles).

So, here's what makes every brand stand out from the other. Take your pick, depending on what you want for your SLR. Happy shopping!

Canon

Snap a photo while you're recording, capture superb stereo sound and start recording while you're in the still-photo mode. Those are just a few things you can do with the PowerShot S3 IS ($338, 6.0 megapixels). In fact, it may be the closest thing you'll find to a hybrid camcorder and camera, all in one. You can zoom or change focus while shooting videos as well, which is a feature that is extremely rare in digital cameras. The movies look fantastic, although a 2 GB card only holds about 18 minutes of footage.

The S3's screen cialis drug impotence is tiny by today's standards at two inches, but on the other hand, it swivels and rotates like a camcorder's screen. With that, you can shoot over your head, down low and so on. To make photographic matters even better, this camera can take 2.3 shots per second in burst mode and it takes macro shots as close as zero inches away. Yes, you can photograph things that are actually touching the lens. Cool, huh?!

Olympus

The main highlight of the ambitious SP-550UZ ($500, 7.1 megapixels) is its super close-up mode. With this, you can shoot subjects only half an inch away. The zoom is astounding (28 to 504 mm, in film terms) and you can practically peer up the nostrils of someone standing at the other end of a football field. What’s more, there’s a 2.5 inch screen that brightens up in dim light to help you see what you're shooting and there's a remarkable on-camera tutorial that teaches you by operating the relevant controls in real time as you hold the camera. In addition to the first ever 18X zoom lens, this one is loaded with unusual goodies. Its burst mode can capture incredible numbers of shots per second at lower resolutions (seven shots at 3 megapixels each, for example). Oddly enough though, if you want full 7 megapixel shots, you only get a sluggish one frame per second.

The menu design isn’t so great on this one either. If you have more money to spare for better features, you could buy a proper digital SLR (the Nikon D40, for example), complete with lens and phenomenal results.

Panasonic

The Lumix DMC-FZ8 ($307, 7.2 megapixels) doesn't offer any special tricks like the Canon or the Olympus, but it offers some standout features, including an actual sliding on/off switch, a rock bottom price tag and the ability to save pictures in a RAW format, which is a rarity among non-SLRs. (RAW format photos use far more space on your memory card than traditional JPEG files, but professionals love RAW files, because specialized software can virtually reshoot them with different settings, after the fact. The Olympus offers RAW shooting as well). The Lumix is a consistent performer without any annoying design quirks. Plus, no "7 megapixels" logo appears on the camera body. For that, Panasonic gets points for breaking ranks with its rivals, who still want you to think that more megapixels means better photo quality.

Nikon

I am at a loss of words for the Nikon D80. With this camera, I am now able to shoot professional looking photos without even trying. The camera is extremely easy to use, even for someone who has never used an SLR before. It has so many preset modes, you can practically shoot in any light condition using one of the photo modes.

The Nikon D80 has some great special effects software built in as well. You can crop, brighten and sharpen photos right on the LCD screen, without even having to transfer them to your computer! All in all, it is a terrific SLR camera and is a benchmark for other 10 megapixel cameras. The Nikon D80 is a very hard product to beat and has brought professional looking photography to the hands of amateurs. This is highly recommended to anyone looking for an entry to mid-level SLR camera.

Sony

The DSC-H5 ($365, 7.2 megapixels) shoots images up to an ISO of 1,000. The camera’s Super SteadyShot optical image stabilization helps produce sharp pictures at long zooms and in low light. If that’s not powerful enough for you, you can buy a VCL-DH1758 telephoto converter to pump up the magnification beyond 20X! Sony also offers the VCL-DH0758 wide angle converter and the VCL-M3358 close-up macro lens. Another thing you notice on the DSC-H5 is its huge three inch screen, which makes the 2.5 inchers on the others (and the two incher on the Canon) look undernourished. Another bonus is the included set of rechargeable batteries with a charger, which is a thoughtful touch.

This camera works best for portraits and architectural shots because of its terrific long zoom. However, because of its small viewfinder and the shutter lag due to a slow processor, the camera isn’t great for capturing moving subjects.

And Finally…

If you're after a mid-size superzoom, you can do much better. You could get the Panasonic for its low price and solid design, the Canon for its remarkable split camera/camcorder personality or the Olympus for its mind boggling zoom. You won't be slipping any of them into your pants pocket, but when you bring home that prize winning shot of the wedding kiss or the soccer goal, all will be forgiven!
