Cisco Fixes Three-Year-Old Telnet Flaw In Security Appliances

jandrese Re:Security + Telnet (60 comments)

Connecting to a device and forwarding packets through it are two different things. It's sensible to have a policy that disallows most users from attempting to ssh to the router's management interface. Often they're on completely different VLANs. It can cause a problem however when the managed connection between the VLANs has an issue and people need to get in there to modify the router settings.

Ubuntu 14.10 Released With Ambitious Name, But Small Changes

jandrese Just what I want (109 comments)

Oh boy, I can't wait for all of the compromises you have to make to get a system usable on a small touchscreen to be ported over to my mouse and keyboard equipped desktop. I hope they go all the way and remove keyboard support so I can hunt and peck with the mouse on an onscreen keyboard with crappy predictive text. Also, make sure every app defaults to fullscreen, because that's what I want on a 3840x2160 display. I also hope they do away with onscreen menus and make everything gigantic buttons because I hate efficient use of screen space.

Cisco Fixes Three-Year-Old Telnet Flaw In Security Appliances

jandrese Re:Security + Telnet (60 comments)

Often times you have to do both, thanks to security policies that prevent user machines from connecting directly with routers/switches. The admin jumps on the box with a serial cable and uses telnet from there to talk to the other equipment.

The Largest Ship In the World Is Being Built In Korea

jandrese Re:inbuilt scrap capabilities (274 comments)

Again, it's the third world. The only thing they care less about than their employee's wages is the environmental damage.

Taking apart a multi thousand ton machine that has been in operation for decades will never be a clean process. You can contain the contamination with a lot of work, but it's never going to be a clean process.

Flight Attendants Want Stricter Gadget Rules Reinstated

jandrese Re:Do it like a virgin (406 comments)

United has a cheesy video too, where the presenter is in a bumpy taxi talking about seatbelts and on a beach talking about stowing tray tables and putting your seats in their full upright and locked position for takeoff. It's only on planes that have video screens though, on smaller and older planes you get the traditional spiel.

The CDC Is Carefully Controlling How Scared You Are About Ebola

jandrese Re:What A Weapon (478 comments)

I'm thinking they would be wiping their nose on their hand first or something. The flaw with this plan is that you have to have someone willing to infect themselves with a horrible disease like Ebola. This is harder than finding regular suicide bombers because Ebola takes a long time to kill you in comparison and the death is so horrible. Also, most people with Ebola are under quarantine, you can can't just walk up and lick them. Then you have to get your Ebola sufferer back to the west before they start showing symptoms and even then everybody flying out of a hot zone is going to come under increased scrutiny. Your Ebola bomber could very well find himself trapped in customs when the symptoms emerge and never carry out the attack.

As always, the devil is in the details.

The CDC Is Carefully Controlling How Scared You Are About Ebola

jandrese Re:Disease spread is fractal (478 comments)

The glut of cases in Liberia are mostly thanks to poor education and unfortunate burial traditions too. In the western developed world there's basically no chance of catching Ebola at the moment. If you know someone who just came back from East Africa then you have a small reason to be concerned, at least for a couple of weeks, but beyond that you can't catch Ebola because there is no Ebola to catch.

The CDC Is Carefully Controlling How Scared You Are About Ebola

jandrese Re:Ebola threat (478 comments)

She got sloppy and didn't follow the procedure properly. When you're dealing with late stage Ebola there is no room for error. Which sucks because you're wearing a sweaty biohazard suit in Africa and dealing with extremely stressed people and chaotic environments where you might be running out of supplies and can do little to help the people regardless. Maintaining strict quarantine procedures is doubly challenging in an environment like that.

CSS Proposed 20 Years Ago Today

jandrese Re:They _Should_ Replace It (180 comments)

CSS Zen Garden examples always kill me because they fall back to fixed positioning (which is horrible on phone screens, and one thing we were trying to get away from with CSS in the first place!) way too often. My first exercise with CSS was to create a slashdot style layout, with fixed columns on the left and right and the remainder of the space taken by an automatically re-flowing column of text/pictures in the middle. For a bonus I wanted the left and right columns to collapse if the screen got too narrow (smartphone). This turned out to be...challenging in CSS.

I also think that too many people threw the baby out with the bathwater when they ditched table based layouts entirely. There are lots of places where you have to got through a lot of effort to replicate in CSS what was relatively easy with tables, like making webforms. That three column layout I mentioned above is also dirt simple to do if you allow yourself to wrap the whole page in a giant table.

Goodbye, World? 5 Languages That Might Not Be Long For This World

jandrese Re:Perl? (547 comments)

Perl 6 is one of the most blatant examples of the Second System Effect in modern times. Perl 5 wasn't exactly small and svelte, but it worked. Perl 6's design had the ambition of fixing all of Perl's problems in one go with a gigantic rewrite and complete rebuilding of the underlying architecture. I'm not saying Perl 5 is the last version of Perl that will ever be widely used, but I am saying that Perl 6 in anything resembling its current incarnation is not likely to be the replacement, especially as more and more of the really useful fixes get backported into Perl 5.

NVIDIA Launches Mobile Maxwell GeForce GTX 980M and GTX 970M Notebook Graphics

jandrese Re:Graphics Card News (29 comments)

An external graphics card is a lot less useful when it's attached to the soda straw of a single PCIe lane. I've seen the idea of external video cards for laptops come up every few years, and the reality of the situation just kills the idea. You have an expensive and awkward dongle that has to be plugged in attached to a bus that's way too skinny to feed it properly and driver issues for days. It's just miserable.

Belkin Router Owners Suffering Massive Outages

Test-Driving a $35 Firefox OS Smartphone

jandrese Re:Why so slow? (132 comments)

It would be quite acceptable fast at loading 1998 webpages I think. The problem is that our demands for our web browsers have gone up. Javascript is remarkably memory hungry, and its performance suffers enormously when memory constrained. Also, FirefoxOS was never intended for a device this constrained, unlike early iOS or Android versions that were built from the ground up to get decent performance on this kind of hardware. Some of the problems sound like straight up bugs too, like the horrendous camera performance. 2MP is absolutely enough to get a decent picture that doesn't look like some abstract painting. That's an encoder error on the phone, and if it had support (it's $35 so probably not) it's something that could be fixed with a firmware patch I'd bet.

Apple Sapphire Glass Supplier GT Advanced Files For Bankruptcy

jandrese Re:How can you (171 comments)

There would have been additional challenges from the fact that both products are manufactured by different companies. I don't think they had anywhere near enough time to take on a risky idea like this for the 6. Once the Sapphire glass failed to pan out they would have already been rushed to place the order for the Gorilla glass replacement.

Apple Sapphire Glass Supplier GT Advanced Files For Bankruptcy

jandrese Re:How can you (171 comments)

The rumor was that Apple was strongly considering Sapphire glass for the 6 and 6+, but discovered that while it has better scratch resistance than the older Gorilla Glass, it has worse shatter resistance, and more people were having trouble with shattered screens than scratched ones already. As someone who had a 4s in his pocket for years with keys, change, and no case I have to say that the scratch resistance of the old glass is remarkable. The glass still looks brand new, although the plastic bevel around the edge looks like hell.

I can definitely see a company getting in financial trouble if it was geared up to manufacture 10 million pieces of glass and had the order suddenly cancelled. They had probably already bought hundreds of millions of dollars of equipment and was getting it set up and ready to go when Apple called up to cancel the order.

jandrese writes "The Lunar Orbiter Image Recovery Project has been recovering and digitizing NASA's old images from the Apollo program from dusty old tapes found in a barn. They are using modern techniques on the old data to achieve stunning results from the old material, but have run out of funding and are looking for help. They have a very modest goal of $75,000 and only 5 days left to reach it."

Verizon CEO: US #1 in Broadband; Because I say so

jandrese jandrese writes  |  more than 4 years ago

jandrese writes "Verizon CEO Ivan Seidenberg went on the record with the Council of Foreign relations to say that the US has far and away the best Broadband in the world, and that the European model has not served its customers nearly as well as the US model. Also how the FCC is making a big mistake if it starts regulating broadband and wireless.

Murray: So on the measures that matter most to you, where does the United States rank in terms of

Seidenberg: One. Not even close.

Seidenberg then goes on to explain how Verizon has laid more fiber than all of the telecom companies in Europe combined, and how Europeans have to carry multiple cell phones if they want to avoid roaming fees. He also promises to go after wireless bandwidth hogs."

Clear Channel wants to clean up XM/Sirius

jandrese jandrese writes  |  more than 6 years ago

jandrese writes "It seems that Clear Channel's terrestrial stations are tired of the XM and Sirius counterparts being free from the FCC decency guidelines, especially after they are forced to pay $1.75 million in fees. To fix the problem they are asking the FCC to impose additional restrictions on the pending XM and Sirius satellite radio merger. In particular, they want the FCC to apply the over the air decency guidelines to all channels on satellite radio. The worst part is that the FCC has not rejected this idea out of hand."

Media Rights Technologies and BlueBeat.com have issued cease and desist letters to both companies and to Adobe Systems Inc and Real Networks — which produce the Adobe Flash Player and Real Player respectively — for actively avoiding their X1 SeCure Recording Control, which they said is an effective copyright protection system.

I guess DRM companies have gotten so used to suing their customers that suing potential customers seems like a good idea."

Why does C not have a heap checking function?

jandrese jandrese writes  |  more than 7 years ago One of the things that has bothered me from the first day I learned about the Memory Management in C over a decade ago is how there is no apparently method in C for knowing how much memory is allocated behind a pointer that you are passed. I asked my teacher back in the day how we would prevent stuff from running off of the end of a buffer if we can't find out how big a buffer is and he just shrugged his shoulders and said "very carefully". It is no surprise to me that buffer overflows are by far the most common form of exploit on C based languages. The worst part is that a lot of that could be avoided with one simple function:

int heapsize(void* buffer, void** start);

Passed in your target pointer it would set the start pointer to the start of the buffer and return the length of the buffer in bytes. Now you would know exactly where your pointer is and how many bytes are left. Bounds checking suddenly gets really simple and buffer overflows, while not completely a thing of the past (lazy programmers would never check), appear far less often.

The normal argument against this function is "it's your program, you should know how big the buffers are", but frankly in an age of libraries and team coding this is just not true.

The worst part is that C already knows this stuff. It has to or the "free" command would not work. It is just hidden away and impossible to get at for some reason. Even with the many revisions of C over the years, it seems like this is one feature we're never going to get. I wonder why?

Mkisofs

jandrese jandrese writes  |  about 11 years ago Why in the world does mkisofs have such a crummy method for specifing what files you want burned?

In case you don't know, here's how it works, you specify one or more directories after the options to mkisofs like so:
mkisofs options_here directory1 directory2 etc...
If directory1 contains the file foo and directory2 contains the file bar, your CD will have foo and bar on the root. Directory1 and directory2 are gone.

This design is as frustrating as it is stupid. If you want to burn directories like that you either have to create a third directory and temporarily move them in there, or create symlinks in the third directory and turn on the (unreliable) -follow-symlinks option (hope you don't have any symlinks in those directories that you cared about).

The worst part is, the correct interface is trivial to implement. If mkisofs didn't get rid of that last directory, it would work perfectly. Using the above line you would get a CD with directory1 and directory2 at the root. If you want the old behavior, all you would have to do is explicitly glob the files like so:
mkisofs options_here directory1/* directory2/* etc...
Maybe it's time to pull out the source...

S-Box mod chip

jandrese jandrese writes  |  more than 11 years ago I've had the S-Box (also called the NeoKey) installed in my PS2 for some time now, and there are a few things I need to get off my chest:

  • Installation: The first problem was that the documentation was wrong. I apparently have the generation 3 PS2, but it has all of the markings of a generation 1 PS2. When I talked to one of the vendors about it, they said that Sony has been doing that to try to thwart the modchip crowd. Ok, they can't do anything about that. What they could do is actually mention that somewhere. I went to at least a dozen different mod sites and none of them had any sort of waring about that whatsoever. Also, they all appear to have copied the instruction pages from a single source, lock stock and barrell. The originals weren't very good though (the pictures were kinda small and fuzzy). Finally, as for the actual process of installation, it was no too bad, except that the PS2 has an incredibly compact PCB, my pencil tip soldering iron was almost too big for that tiny little patch I had to solder on. I'm also not sure if that USB port will ever be usable again (I suspect not). Fortunatly almost nothing on the PS2 uses the USB port.
  • Import/Burned PSx games: The chip works as advertised sometimes, and lets me play DDR on my US PS2, however it is rather flaky, only working about 50% of the time and requiring a reboot the other times. I've found that it works best if you power the PS2 completely off (using the switch in the back) and back on when trying to play an import. It does blink ALL of the time when it is on however, which is rather annoying (fortunatly the light is covered up by the controller plugs).
  • Import/Burned PS2 games: there were some conflicting reports on the sites about support for Ps2 games. Apparently you need a Gameshark, and even then you can only play PS2 games that are burned on CDr. I suppose that would be fine for pirates, but all I really care about are import games. I guess I'll just be playing the PSx imports instead. Also, instead of a Gameshark, I already had a Code Breaker. The Code Breaker is apparently not sufficent, as it does not work. Actaully, I havn't had a gameshark to test with either, so I don't know if it works at all.
  • Final Verdict: If your soldering skills are only so-so, and you only want to play PSx games, and don't mind a bit of a headache in the install procedure, then this is an acceptable modchip. It is also reasonably inexpensive compared to some of the more full featured mods.
