  1. The only other thing I can think of is when I turn on my computer there's a warning about Time Machine backup disk being unrepairable or something like that.

    Do you have an online backup program running? Or another program constantly accessing the Internet?

    Do your speed tests speeds vary, or stay about the same speed range.

    EDIT: Time machine(which you have) versus Time capsule(which has some faulty units out there).

    http://reviews.cnet.com/8301-13727_7-20010237-263.html

    Apple has acknowledged a problem with time capsule devices released between February and June in 2008, where the devices will not turn on or will randomly shut down after starting up. This may cause hangs and other interruptions in Time Machine backups as well as other network activity.

    In a recently released knowledgebase document, Apple provides a range of serial numbers (XX807XXXXXX - XX814XXXXXX) which may contain problematic components that lead to the power problems. If your Time Capsule is in that range, and you are experiencing these problems, Apple will replace the unit free of charge if you take it in to an Apple store or another authorized Apple service provider.

    This replacement program will cover devices for up to three years from the date of purchase, so you have until June 2011 to get the device replaced. If you need to retrieve your data off the Time Capsule, Apple will provide some options to do so; however, you should first try to get it off yourself because Apple claims no responsibility for lost data.

    UPDATE: This replacement program is not a recall by Apple, so if you have a working Time Capsule Apple will not replace it with a new one. Instead, the program is basically a warranty extension for a specific serial number range of devices, and will only be observed if your device has the symptoms described here. If your Time Capsule is in the range of serial numbers listed but does not have any symptoms, you will probably not have any luck getting it replaced. Likewise for if your device has similar symptoms but is not within the serial number range listed.

  2. Yeah, I've rebooted the modem several times. I believe it's a 2007 or 2008 iMac. I have no other computers on the network. I just noticed a very small crack on one end of the ethernet cable so I'm going to get a new one today and hopefully that is the problem. What are the odds that is the problem? Not very good?

    Even ethernet cables that look good, can go bad. Helps to have spare parts around, when something goes weird. I have a nice pile of stuff next to my desk. :laugh:

  3. WalMart is going to be the first big store to put RFID's on clothing(for inventory). The tags, at the moment, will be removable to hopefully prevent privacy issues of other places using that RFID to track you. Just throw the tag into WalMarts trashcan outside.

    And since the RFID is probably not encrypted, Whats to stop a criminal from getting a scanner and scanning car trunks in the parking lot for fresh goods, as the RFID program gets expanded.

    And will the stores scanners at the door try to read your RFID drivers license? Oh and that RFID credit card. Bad security on both of those by inserting RFID's.

    Forget the bar code on the babies forehead when they are born. Just give them WalMart onesies and send them out in the world.

    Washington State University hacked those Drivers License RFID's in a split second and put someone else's data on the card(a mock up to be legal about it) that wasn't the persons name on the card. http://rfid.cs.washington.edu/

    http://online.wsj.com/article/SB10001424052748704421304575383213061198090.html

    Wal-Mart Stores Inc. plans to roll out sophisticated electronic ID tags to track individual pairs of jeans and underwear, the first step in a system that advocates say better controls inventory but some critics say raises privacy concerns.

    Starting next month, the retailer will place removable "smart tags" on individual garments that can be read by a hand-held scanner. Wal-Mart workers will be able to quickly learn, for instance, which size of Wrangler jeans is missing, with the aim of ensuring shelves are optimally stocked and inventory tightly watched. If successful, the radio-frequency ID tags will be rolled out on other products at Wal-Mart's more than 3,750 U.S. stores.

    "This ability to wave the wand and have a sense of all the products that are on the floor or in the back room in seconds is something that we feel can really transform our business," said Raul Vazquez, the executive in charge of Wal-Mart stores in the western U.S.

    Before now, retailers including Wal-Mart have primarily used RFID tags, which store unique numerical identification codes that can be scanned from a distance, to track pallets of merchandise traveling through their supply chains.

    Wal-Mart's broad adoption would be the largest in the world, and proponents predict it would lead other retailers to start using the electronic product codes, which remain costly. Wal-Mart has climbed to the top of the retailing world by continuously squeezing costs out of its operations and then passing on the savings to shoppers at the checkout counter. Its methods are widely adopted by its suppliers and in turn become standard practice at other retail chains.

    But the company's latest attempt to use its influence—executives call it the start of a "next-generation Wal-Mart"—has privacy advocates raising questions.

    While the tags can be removed from clothing and packages, they can't be turned off, and they are trackable. Some privacy advocates hypothesize that unscrupulous marketers or criminals will be able to drive by consumers' homes and scan their garbage to discover what they have recently bought.

    They also worry that retailers will be able to scan customers who carry new types of personal ID cards as they walk through a store, without their knowledge. Several states, including Washington State and New York, have begun issuing enhanced driver's licenses that contain radio- frequency tags with unique ID numbers, to make border crossings easier for frequent travelers. Some privacy advocates contend that retailers could theoretically scan people with such licenses as they make purchases, combine the info with their credit card data, and then know the person's identity the next time they stepped into the store.

    "There are two things you really don't want to tag, clothing and identity documents, and ironically that's where we are seeing adoption," said Katherine Albrecht, founder of a group called Consumers Against Supermarket Privacy Invasion and Numbering and author of a book called "Spychips" that argues against RFID technology. "The inventory guys may be in the dark about this, but there are a lot of corporate marketers who are interested in tracking people as they walk sales floors."

    Smart-tag experts dismiss Big Brother concerns as breathless conjecture, but activists have pressured companies. Ms. Albrecht and others launched a boycott of Benetton Group SpA last decade after an RFID maker announced it was planning to supply the company with 15 million RFID chips.

    Benetton later clarified that it was just evaluating the technology and never embedded a single sensor in clothing.

    Wal-Mart is demanding that suppliers add the tags to removable labels or packaging instead of embedding them in clothes, to minimize fears that they could be used to track people's movements. It also is posting signs informing customers about the tags.

    "Concerns about privacy are valid, but in this instance, the benefits far outweigh any concerns," says Sanjay Sarma, a professor at the Massachusetts Institute of Technology. "The tags don't have any personal information. They are essentially barcodes with serial numbers attached. And you can easily remove them."

    In Europe some retailers put the smart labels on hang tags, which are then removed at checkout. That still provides the inventory-control benefit of RFID, but it takes away other important potential uses that retailers and suppliers like, such as being able to track the item all the way back to the point of manufacture in case of a recall, or making sure it isn't counterfeit.

    Wal-Mart won't say how much it expects to benefit from the endeavor. But a similar pilot program at American Apparel Inc. in 2007 found that stores with the technology saw sales rise 14.3% compared to stores without the technology, according to Avery Dennison Corp., a maker of RFID equipment.

    And while the tags wouldn't replace bulkier shoplifting sensors, Wal-Mart expects they'll cut down on employee theft because it will be easier to see if something's gone missing from the back room.

    Several other U.S. retailers, including J.C. Penney and Bloomingdale's, have begun experimenting with smart ID tags on clothing to better ensure shelves remain stocked with sizes and colors customers want, and numerous European retailers, notably Germany's Metro AG, have already embraced the technology.

    Robert Carpenter, chief executive of GS1 U.S., a nonprofit group that helped develop universal product-code standards four decades ago and is now doing the same for electronic product codes, said the sensors have dropped to as little as seven to 10 cents from 50 cents just a few years ago. He predicts that Wal-Mart's "tipping point" will drive prices lower.

    "There are definitely costs. Some labels had to be modified," said Mark Gatehouse, director of replenishment for Wrangler jeans maker VF Corp., adding that while Wal-Mart is subsidizing the costs of the actual sensors, suppliers have had to invest in new equipment. "But we view this as an investment in where things are going. Everyone is watching closely because no one wants to be at a competitive disadvantage, and this could really lift sales."

    Wal-Mart won't disclose what it's spending on the effort, but it confirms that it is subsidizing some of the costs for suppliers.

    Proponents, meanwhile, have high hopes for expanded use in the future. Beyond more-efficient recalls and loss prevention, RFID tags could get rid of checkout lines.

    "We are going to see contactless checkouts with mobile phones or kiosks, and we will see new ways to interact, such as being able to find out whether other sizes and colors are available while trying something on in a dressing room," said Bill Hardgrave, head of the RFID Research Center at the University of Arkansas, which is funded in part by Wal-Mart. "That is where the magic is going to happen. But that's all years away."

    "Contact chip" credit card with stupid RFID inlay. The credit card had the "contact chip" added for security and now they are adding RFID's for the lazy idiots who don't care about security. Just wave your wallet or purse in front of the scanner to pay for your product.

  4. If people want to know what an Iframe attack is.....

    Easy way to beat it, is to keep your Operating system updated with patches and to keep your browser updated. And run a Anti-virus program.

    'XP service pack 2' has now come to end of life cycle. So 'XP service pack 3' is the current supported cycle, for awhile. And Internet Explorer '6' is no longer supported for patches. Microsoft's site will point you to Internet Exploder 8. Windows 7 is a very stable operating system.

    I have hit a few malicious(a lot worse than an Iframe) links embedded in Blogs. But Avast anti-virus puts up a block of the malicious weblink, so I can still see the Blog.

    http://www.guardian.co.uk/technology/2008/apr/03/security.google

    3 April 2008

    What's an IFrame attack and why should I care?

    It's now a popular way of trying to load malware onto users' PCs without them going to an evil or compromised website. In fact, they only have to click on a link in a Google search for a popular site, where the exploit has been preloaded. Sites affected include USA Today, Wal-Mart and ZD Net Asia, but it's spreading.

    An IFrame (which isn't another Apple product - it stands for "inline frame") is just a way of loading one web page inside another, usually from a different server. That can be useful for building online applications. But malware writers can make the included page just one pixel square - meaning you can't even see it's there - and obfuscate the JavaScript that will run automatically from that included page so that it looks something like %6C%20%66%72%61%6D%65%62%6F - leaving no obvious clue that it's malicious.

    When this idea got going, the IFrame code would be inserted by hacking web servers, or adding it to banner advertisements. Over the past six months, however, there has been a huge growth in the use of "poisoned" search results.

    Big websites often cache (store) the results of search queries run on their sites - say, the links for a search for "malware IFrame" - and then forward these to search engines such as Google, which can generate search results directly. Malware authors exploit the system by putting in a search query like "malware IFrame" plus all the malicious IFrame's text. If the site doesn't check search terms adequately for obfuscated Javascript, the IFrame data is stored and passed on. When someone then searches for "malware IFrame" and clicks a result, the attack is initiated directly from the search result, because the browser can read the obfuscated Javascript - even if you can't.

    Malware distributors like this because they don't need to hack the server, and can use popular searches to benefit from the site's SEO (search engine optimisation) practices and get a high ranking at Google. The attack usually includes half a dozen "drive-by" exploits, and also uses "social engineering" to get users to install something else, such as a video codec that is actually a Trojan. Windows users without the IE security update MS04-040 (from 2004!) are particularly vulnerable. There seem to be lots of them.

    How can the attacks be stopped? Sites that cache searches must improve their input checking, and server operators can search for IFrame exploit code. Google is trying to remove malware search results, and automatically detects some exploits and warns that "This site may harm your computer".

    Windows users should make sure they have installed all security updates, and preferably upgrade to XP SP2 with IE7 XP SP3 and IE 8, or Vista Windows 7. Running an active anti-malware guard can also help. That should just leave the people dumb enough to think they need to install a new codec to view porn.

  5. :smitten:

    Using the new Bell Turbo Hub ( bell mobility) 40.00 per month--includes 3 gigabit--automatically adjusts cost on levels up to 10gigabit. monthly--price levels very reasonable.

    capaple of reaching speeds of 7mbs down and 5.5 mbs up--check out the upload --1.6 mbs--Speeds can improve with antenna--indoor or outdoor Yagi.

    I am rural so the outdoor will be installed.. Have been with xplornet sattellite ( hughes) 2mb package 170.00 per month--upload supposed to be 300kps--never more than around 225

    This is 1/4 cost and way faster--like having a DSL or Cable.

    And don't forget the 'low latency' over what satellite is.

  6. Hello all! I recently moved and had gotten Verizon DSL. I am suppose to be getting 6.2 MB but for some reason when I do a speed test all I get is 5.37 MB down. I am using the 6100G Westell modem (bridged) to a Linksys WRT54G2. Any help would be appreciated.

    Is your speed supposed to be at 6.2Mbps or is there overhead taken off that, so you end up a bit slower? Which makes your speed number about right.

    With the Telus DSL that I am on, my package is 6Mbps, but my speed is 5.2Mbps due to 'over head'. The faster the speed package, the more overhead to deal with.

    Can that modem see it's "tranceiver stats", or line stats. which is attenuation, etc. Since the distance to the node and line noise would affect maximum speeds.

  7. Not trying to turn this into a Mac vs. PC thing but if you were to actually look at a Mac long and hard you would see that for what you get it really doesn't cost that much. Take the 27" iMac for example the display alone costs $1099 http://accessories.us.dell.com/sna/products/Displays/productdetail.aspx?c=us&l=en&s=dhs&cs=19&sku=224-8284&~ck=bn&~bk=gr:CategoryRec,g:NextStep,rk: and Apple only charges $1699 for the display with the computer.

    Well now that you put it that way............... Actually I keep forgetting that Apple still has that computer in a TV screen Imac. And those Screen specs are really good.

    PC makers keep trying to do Computer in a screen, but usually they do that touch screen crap. It's crap cause many people have greasy fingers and keep smearing the screen over the day. The shopping channel is funny to watch as the smears increase over the course of the hour. And whatever PC they are selling is slightly underpowered to deal with touch screen technology and bring up the programs at the same time, so there ends up being a delay from the time of touch to the launch of the program. And a million Windows get opened, by the host, in the process, slowing it down even more.

  8. well this thread was popular

    The hard core MAC addicts are busy trying to find 'duct tape' for their Iphone4 and all they can find is 'duck tape' in the store, so they have to keep going from store to store until they can find some sticky gray tape. Some places only have sticky black tape. And the stuff in the dollar store only lasts so long before it falls off.

  9. i'll post this question here too...

    okay time to put an AV on here...what's the recommendation for ubuntu??

    https://help.ubuntu.com/community/Antivirus

    And then this link for Avast download link to Avast's site, install instructions, how to get free license key, etc.

    http://www.ubuntugeek.com/avast-antivirus-for-ubuntu-desktop.html

    Note that some of the anti-virus products will just identify a virus and quarantine it.

    A Windows virus can run in Linux if you have 'Wine' installed to run some Windows programs.

    If you hit a site with one of those fake virus scanners in Linux, you can laugh at it, with it saying you are infected in a Windows machine file system.

    But not many virus can attack Linux with it being open source and the OS constantly updated for any virus threat. And it is more fun to make a virus for Windows machines with all it's exploits.

  10. thanks for your answer, i only have one question, why does the online scan detect virus that kaspersky doesn't?, i'm doing the panda active scan 2.0 and has detected 18 virus

    The virus scanners all have slightly different definitions. And depending on how 'new' a virus is and if the anti-virus company has created a definition to identify it.

    A installed anti-virus can update every day(or hour) to the latest definitions.

    Kaspersky's online scanner updates definitions every hour. http://www.kaspersky.com/kos/english/languages/english/check.html?n=1278638804597

    But sometimes you can have a virus that hides in a file folder and after you remove the infection, the virus will reinstall itself, so you are infected again without a installed anti-virus running to put a stop to it. And those take a bit more work to clean out.

    Some virus will modify themselves on the machine, so the scanner will not see them, until the anti-virus data base is updated again. So thats why a software firewall is nice. Even though some infections will tag along or masquerade with another 'safe 'program to try and by-pass the firewall.

    And when you find a virus, it is safer to put them into the 'virus chest', instead of instant delete, just in case it was a safe file that belongs to the operating system.

  11. Thanks for answering, yesterday i downloaded the kaspersky trial version and right now i'm downloading a game and my download speed has increased to 64 kb/s,(the normal is 100 kb/s) but as zalternate said my system slowed down and it has detected 2 troyans until now so, i think i'm gonna try avast, and Do you think i should install avast and Malwarebytes or only avast?, and Do think i should continue with the online scan or only with avast??

    MalWareBytes 'free version' does not run unless you start it, so no conflicts with the anti-virus program. And also you have to manually update the free version. But it still has the same system scanning as the paid version. so you install it and then just leave it sit there until you do a weekly or monthly scan. Just update it first. It's a quick way to check for obvious bugs.

    Install Avast. And only run one Anti-virus on the computer. Uninstall kaspersky via it's uninstall program.

    Online scans are okay provided you have the bandwidth needed for some of them. But online scanning is generally done when someone thinks they are infected already.

    But generally Avast should keep your system good. You can manually or automated scan your computer with Avast and it also will scan incoming files or when they launch, so you have much better protection than an online scan.

    After you get things cleaned up, you could also try the ZoneAlarm firewall, if you are still having a speed issue.

  12. thanks tommie and zalternate right now i'm doing an online scan because i don't have antivirus and until now the online scan have found 18 infected files, and i'm thinking in instaling mcafee or kaspersky which one do you recommend??

    Avast is free and a very good anti-virus. And no bloat to slow your system down.

    When you download, it will give you a free key that you renew once a year for free. It gets emailed to you.

    Edit: and you can change the "get new definitions" to once a day instead of about 4 times a day.

    Also turn off the voice. It does scare people when they hit an infected site.

    And even if you are behind a router, having a 'software' firewall can help to stop nasties from getting out if any anti-virus program misses something. It also stops Windows junk from calling home.

  13. I am kinda thinking is anyone still on Vsta? or is it a clear cut fight betweem XP and 7 ,?

    maybe a poll is needed ,?

    win 98

    win M.e ,( never had a problem with it )

    XP

    Vista ( makes me think of visit but ain't staying )

    Win 7

    or are you a mac fan ? ,far to rich in this dog eat dog world ,

    BTW I started out with win 3.,1 ,and no I dont want to go back icon_biggrin.gif

    I've got a pole for Vista. It's called Linux. It clears that Vista right out of the machine in one clean swipe.

  14. I just put my wireless stick on my Ubuntu 10.4 box and my router is at WEP 128bit/passphrase(for the kids DS,otherwise it would be set to better encryption, but my machines are software firewalled anyways) and Ubuntu using wep 128bit encryption with passphrase did not work, but Ubuntu using wep 128bit encryption worked. I had already entered routers passphrase for the security.

    But I would also have to do something to get the firewall working with firestarter with wireless. But the Ubuntu machine is wired anyways.

  15. And the "Right to blow stuff up on the 4th of July", is fun until you lose an arm. But at least it wasn't his head. So he's not in the top end running for this years Darwin award. http://www.darwinawards.com/

    4th of July News: Fireworks Blow of Man’s Arm in NY and More

    July 4th, 2010

    4th of July News: Fireworks Blow of Man’s Arm in NY and More. Independence day is here, and everyone is getting ready to shoot off some fireworks. There are rules and regulations in place, and some fireworks are illegal. There is a reason for this, as one New York City man discovered the hard way. Eric Smith went to light a firework, didn’t back away in time, and then got his arm torn off as the firework went off.

    Not only did Eric Smith lose his arm, but the city may bring charges against him because the fireworks were illegal. Smith was rushed to the hospital with his arm packed in ice, but the medical officials were unable to re-attach his arm to his body. He’s going to survive.

  16. That ISP Xipline(cable based operator) has the internal based speed test that I mentioned. Now it depends on how much slower he is than the package speed listed.

    And the other thing is to make sure there are not any splitters on the cable line he is connected too. Only split in the DeMarc box

    (grey box on house) and then a dedicated run to the modem.

    But since the ISP speed test is showing good, that may not be a problem.

    A tracert could also be run to here to see if any bottle necks outside of the ISP.
