  • How do I get my Lenovo T61 to connect to a wireless network?

    - by Ross Fleming
    I have a Lenovo Thinkpad T61 and the wireless works just fine so I installed Ubuntu straight away only to find that the wireless will not connect, it will see the networks but just not connect. Has anyone managed to solve this all the forums seem to relate to Ubuntu 9.04 and before. Edit:Sorry about that, I didn't realise that there were 2 models mine is the Intel Corporation PRO/Wireless 4965 AG or AGN [Kedron] Network Connection. Any help is much appreciated.

  • How can I make NetworkManager ignore my wireless card?

    - by ændrük
    I do not want NetworkManager to list or manipulate my wireless card. Can I hide its interface from NetworkManager somehow? I have tried adding this in /etc/network/interfaces, iface wlan0 inet static address 192.168.1.101 netmask 255.255.255.0 gateway 192.168.1.1 wireless-essid Synaptotagmin pre-up wpa_supplicant -B -i wlan0 -c /etc/wpa_supplicant.conf post-down killall -q wpa_supplicant and this in /etc/NetworkManager/nm-system-settings.conf, [main] plugins=ifupdown,keyfile [ifupdown] managed=false [keyfile] unmanaged-devices=/org/freedesktop/Hal/devices/net_00_19_e0_57_86_af but NetworkManager Applet still lists and allows me to connect to wireless networks.

I can order flowers for my wife while flying 30,000 feet in the air. I can order my groceries in the subway and have them delivered later that day. I can even see how clothes look on me without setting foot in a store. Who knew that a TV, diamond necklace, or even a car would someday be as easy to purchase as a candy bar? Can technology make a mattress an impulse item? Wake-up and your back is hurting, so you rollover and grab your iPad, then a new mattress is delivered the next day. Behind the scenes the many processes are being choreographed to make the sale happen. This includes moving data between systems with the least amount for friction, which in some cases is near real-time. But real-time isn’t appropriate for all the integrations. Think about what a completely real-time retailer would look like. A consumer grabs toothpaste off the shelf, and all systems are immediately notified so that the backroom clerk comes running out and pushes the consumer aside so he can replace the toothpaste on the shelf. Such a system is not only cost prohibitive, but it’s also very inefficient and ineffectual. Retailers must balance the realities of people, processes, and systems to find the right speed of execution. That’ what “right-time retail” means. Retailers used to sell during the day and count the money and restock at night, but global expansion and the Web have complicated that simplistic viewpoint. Our 24hr society demands not only access but also speed, which constantly pushes the boundaries of our IT systems. In the last twenty years, there have been three major technology advancements that have moved us closer to real-time systems. Networking is the first technology that drove the real-time trend. As systems became connected, it became easier to move data between them. In retail we no longer had to mail the daily business report back to corporate each day as the dial-up modem could transfer the data. That was soon replaced with trickle-polling, when sale transactions were occasionally sent from stores to corporate throughout the day, often through VSAT. Then we got terrestrial networks like DSL and Ethernet that allowed the constant stream of data between stores and corporate. When corporate could see the sales transactions coming from stores, it could better plan for replenishment and promotions. That drove the need for speed into the supply chain and merchandising, but for many years those systems were stymied by the huge volumes of data. Nordstrom has 150 million SKU/Store combinations when planning (RPAS); The Gap generates 110 million price changes during end-of-season (RPM); Argos does 1.78 billion calculations executed each day for replenishment planning (AIP). These areas are now being alleviated by the second technology, storage. The typical laptop disk drive runs at 5,400rpm with PCs stepping up to 7,200rpm and servers hitting 15,000rpm. But the platters can only spin so fast, so to squeeze more performance we’ve had to rely on things like disk striping. Then solid state drives (SSDs) were introduced and prices continue to drop. (Augmenting your harddrive with a SSD is the single best PC upgrade these days.) RAM continues to be expensive, but compressing data in memory has allowed more efficient use. So a few years back, Oracle decided to build a box that incorporated all these advancements to move us closer to real-time. This family of products, often categorized as engineered systems, combines the hardware and software so that they work together to provide better performance. How much better? If Exadata powered a 747, you’d go from New York to Paris in 42 minutes, and it would carry 5,000 passengers. If Exadata powered baseball, games would last only 18 minutes and Boston’s Fenway would hold 370,000 fans. The Exa-family enables processing more data in less time. So with faster networks and storage, that brings us to the third and final ingredient. If we continue to process data in traditional ways, we won’t be able to take advantage of the faster networks and storage. Enter what Harvard calls “The Sexiest Job of the 21st Century” – the data scientist. New technologies like the Hadoop-powered Oracle Big Data Appliance, Oracle Advanced Analytics, and Oracle Endeca Information Discovery change the way in which we organize data. These technologies allow us to extract actionable information from raw data at incredible speeds, often ad-hoc. So the foundation to support the real-time enterprise exists, but how does a retailer begin to take advantage? The most visible way is through real-time marketing, but I’ll save that for part 3 and instead begin with improved integrations for the assets you already have in part 2.

  • Can't connect to or search Wi-Fi

    - by Mark
    I just installed the latest version of Ubuntu; I think it was 13 or something. Anyway, I got it running, and now I've been trying to connect to my Wi-Fi AP. No matter where I go I don't see an option for Wi-Fi. I looked on the computer and found some commands to use in a terminal to run a scan for Wi-Fi networks, but all of them returned the error: interface doesn't support scanning What are step-by-step directions to make this work?

  • What are different ways to reduce latency between a server and a web application? [closed]

    - by jjoensuu
    this is a question about a web application that provides SOAP web services. For the sake of this question, this web app is hosted on a server SERVER B which is located in California. We have an automated, scheduled, process running on a server SERVER A, located in New York. This scheduled process is supposed to send SOAP messages to SERVER B every so often, but this process typically dies soon after starting. We have now been told by the vendor that reason why the process dies is because of the latency between SERVER A and SERVER B. The data traffic is routed through many diffent public networks. There is no dedicated line between SERVER A and SERVER B. As a result I have been asked to look into ways to reduce the latency between SERVER A and SERVER B. So I wanted to ask, what are the different ways to reduce latency in a situation like this? For example, would it help to switch from HTTPS to some other secure protocol? (the thought here is that perhaps some other alternative would require fewer handshakes than HTTPS). Or would a VPN help? If a VPN would reduce the latency, how would it do that? NOTE: I am not looking for an explicit answer that would work in my specific situation. I am more like looking just for a simple list of what technologies could be used for this. I will still have to evaluate the technologies and discuss them internally with others, so the list would just be a starting point. Here I am assuming that there exists very few ways to reduce latency between two servers that communicate across public networks using HTTPS. Feel free to correct me if this assumption is wrong and please ask if there is a need for specific information. NOTE 2: A list of technologies is a specific answer to the question I stated in the title. NOTE 3: Its rather dumb to close this question when it is after all about me looking for information and furthermore this information can clearly be useful for others. Anyway luckily there are other sites where I can ask around. StackExchange seems to attached to their own philosophical principles. Many thanks

  • How can I advetise efficiatly on my sites? [on hold]

    - by Smillification
    Are there any ad networks that give publishers/websites the ability to display adverts that are chosen by the publisher immediately on page load. Lets say the page loads, and a script inserts certain key words that the ad network uses to search their inventory of adverts and assigns the nearest one with matching tags to the publisher advert area? I know Google's adsense and many other similar services index/reads the pages content and then assign certain advert depending on the content with little or no control by the publisher... Any help is appreciated.

  • USB Wifi will not connect on Windows 7 (Even though the driver installs OK)

    - by Pete Roberts
    Windows 7 will not connect to a WiFi Netowrk using a USB Network Adapter. I have 3 adapters, A Senoa SUB 364 (EXT), a Repeatit SU2410 USB V2 and a ZYXEL G202. All of these devices install OK on Windows 7 Home Premium on my Destop PC (64 bit) and on my Asus Wii Netbook (32 bit). In each case the adapter can be enabled/disabled and the driver properties says it is working correctly. When I try and connect to a network Windows 7 behaves as though the adapter does not exist and reports no networks. The Wii has an integrated adapter which works perfectly under Windows and connects to either of the 3 networks available to me. I have done all the checks I can on the configuration. What seems odd to me is that it happens to all 3 devices on 2 different windows 7 PCs both of which are working perfectly in any other respect. This suggests the common denominator is me and I must be doing something wrong.. what's also strange is that I cannot find any similar problems being reported on any of the forums. From what reading I've been able to do it seems like the new wifi virtualisation thingy in W7 is not recognising the adapters which suggests I', missing a configuration option somewhere. Looking forward to finding out if I'm not alone or just being stupid. Pete
