  • Internet Troubles - PPPoE vs PPPoA?

    - by AkkA
    I have been having some internet troubles at home (ADSL2+ connection in Australia). We get random drop-outs from the authentication connection. It will keep the connection to the DSL service, but we lose authentication and either have to restart the router/modem (its combined, a Belkin one, not sure on model number) or unplug the phone cable, wait about 30 seconds and plug it in again. I've called the ISP (Telstra) a few times, but they only offer limited support when we dont use their supported hardware. Apparently something had happened on their side, they checked the box again (at least it sounded that simple), and told me it would be fine. It wasnt. I've replaced all the filters around the house, but that didnt help either. We do live a little bit away from the exchange (get a sync speed of about 3000/900), so I thought it could be due to line noise but that hasnt helped. Telstra allow both PPPoE and PPPoA connections (which I'm configuring through my router, dont have software on the PC side). I've been running PPPoA the whole time, would it make any difference changing it to PPPoE? If not, are there any other theories as to why we would be experiencing these drop-outs? It has been fine for at least 12 months, then suddenly started about 2 months ago.

  • Geocoding non-addresses: Geopy

    - by Phil Donovan
    Using geopy to geocode alcohol outlets in NZ. The problem I have is that some places do not have street addresses but are places in Google Maps. For example, plugging: Furneaux Lodge, Endeavour Inlet, Queen Charlotte Sound, Marlborough 7250 into Google Maps via the browser GUI gives me However, using that in Geopy I get a GQueryError saying this geographic location does not exist. Here is the code for geocoding: def GeoCode(address): g=geocoders.Google(domain="maps.google.co.nz") geoloc = g.geocode(address, exactly_one=False) place, (lat, lng) = geoloc[0] GeoOut = [] GeoOut.extend([place, lat, lng]) return GeoOut GeoCode("Furneaux Lodge, Endeavour Inlet, Queen Charlotte Sound, Marlboroguh 7250") Meanwhile, I notice that "Eiffel Tower" works fine. Is there away to solve this and can someone explain the difference between The Eiffel Tower and Furneaux Lodge within Google 'locations'?

  • svchost.exe @ 100% disk utilization vs. Outlook.ost

    - by Aszurom
    Vista x32 box with Outlook 2007. Outlook is not running. Hasn't been fired up for several reboots. I stopped WMI service and Windows Search service. Machine is mostly quiet, and then servicehost.exe launches an instance and starts banging away at Outlook.ost file. I can't determine what is causing it. I'm watching it in processmon, and trying to investigate it with preocessexplorer. Not having much luck at figuring out why the machine is so interested in that file. NOTHING is running that should be touching it.

  • OPTIONS request vs GET in Ajax

    - by user41172
    I have a PHP/javascript app that queries and returns info using an ajax request. On every server I've used so far, this works as expected, passing an Ajax GET request to the server and returning json data. On a new install, the query fails and returns nothing-- I inspected the request and it turns out that rather than passing the query as a GET, the server is passing it as an OPTIONS request. Is there any reason for this? I have no idea why this might happen. THanks!

  • Puppet yum repo - Pull down 2.7.x vs 3.0.x

    - by Mike Purcell
    So a few weeks ago I started on the path to using puppet to automate all the configs/services. At the time I was using the EPEL repo, which installed version 2.6.x. After some reading I was trying to gain access to the flatten method available via the puppet stdlib, and thought it was available by default in the newer 2.7.x version. So I added a puppet repo with the following settings: [puppetlabs] name=Puppet Labs Packages baseurl=http://yum.puppetlabs.com/el/$releasever/products/$basearch/ enabled=1 gpgcheck=1 gpgkey=http://yum.puppetlabs.com/RPM-GPG-KEY-puppetlabs The problem with this, is it installed v3.0.x instead of 2.7.x. And apparently 3.0.x is a major upgrade which was released only a few weeks ago. Obviously I would prefer to use the 2.7.x for the next few months while PuppetLabs fix any defects which will inevitably arise after a major version. So my question is, what setting can I add to the puppet repo config to pull down only the 2.7.x branch and not the 3.0.x branch?

  • Updating Excel Cell with Non-Numeric Data in C#

    - by kbo206
    I have a query that is ExcelQuery = "Update [Sheet1$] set CITIZEN_ID = #" + value + " where CITIZEN_ID = " + value; As you can see, I'm essentially just appending a "#" onto the CITIZEN_ID field. value is a int/numeric value. So if I had "256" in the CITIZEN_ID column it would be converted to "#256" When I execute this I get an OleDbException Syntax error in date in query expression so I surrounded part of the query in single quotes like this, ExcelQuery = "Update [Sheet1$] set CITIZEN_ID = '#" + value + "' where CITIZEN_ID = " + value; With that I get yet another OleDbException this time with, Data type mismatch in criteria expression. I'm guessing for some reason the CITIZEN_ID fields don't want to take anything besides a plain number. Is there any way I can remedy this to get that pound symbol in? Thanks!

  • Rails' page caching vs. HTTP reverse proxy caches

    - by John Topley
    I've been catching up with the Scaling Rails screencasts. In episode 11 which covers advanced HTTP caching (using reverse proxy caches such as Varnish and Squid etc.), they recommend only considering using a reverse proxy cache once you've already exhausted the possibilities of page, action and fragment caching within your Rails application (as well as memcached etc. but that's not relevant to this question). What I can't quite understand is how using an HTTP reverse proxy cache can provide a performance boost for an application that already uses page caching. To simplify matters, let's assume that I'm talking about a single host here. This is my understanding of how both techniques work (maybe I'm wrong): With page caching the Rails process is hit initially and then generates a static HTML file that is served directly by the Web server for subsequent requests, for as long as the cache for that request is valid. If the cache has expired then Rails is hit again and the static file is regenerated with the updated content ready for the next request With an HTTP reverse proxy cache the Rails process is hit when the proxy needs to determine whether the content is stale or not. This is done using various HTTP headers such as ETag, Last-Modified etc. If the content is fresh then Rails responds to the proxy with an HTTP 304 Not Modified and the proxy serves its cached content to the browser, or even better, responds with its own HTTP 304. If the content is stale then Rails serves the updated content to the proxy which caches it and then serves it to the browser If my understanding is correct, then doesn't page caching result in less hits to the Rails process? There isn't all that back and forth to determine if the content is stale, meaning better performance than reverse proxy caching. Why might you use both techniques in conjunction?

  • Increment non unique field during SQL insert

    - by phill
    I'm not sure how to word this cause I am a little confused at the moment, so bare with me while I attempt to explain, I have a table with the following fields: OrderLineID, OrderID, OrderLine, and a few other unimportant ones. OrderLineID is the primary key and is always unique(which isn't a problem), OrderID is a foreign key that isn't unique(also not a problem), and OrderLine is a value that is not unique in the table, but should be unique for any OrderIDs that are the same...so if that didn't make sense, perhaps a picture OrderLineID, OrderID, OrderLine 1 1 1 2 1 2 3 1 3 4 2 1 5 2 2 For all OrderIDs there is a unique OrderLine. I am trying to create an insert statement that gets the max OrderLine value for a specific OrderId so I can increment it, but it's not working so well and I could use a little help. What I have right now is below, I build the sql statement in a program and replace OrderID # with an actual value. I am pretty sure the problem is with the nested select statement, and incrementing the result, but I can't find any examples that do this since my google skills are weak apparently.... INSERT INTO tblOrderLine (OrderID, OrderLine) VALUES (<OrderID #>, (SELECT MAX(OrderLine) FROM tblOrderLine WHERE orderID = <same OrderID #>)+1) any help would be nice.

  • SQL Server: Statements vs. Batches vs. Transactions vs. Connections

    - by Sleepless
    My question is simple: What are the differences / similarities / cardinalities between Transactions Batches Connections and Statements in SQL Server? As far as I understand a connection is a single communications channel between a SQL Server instance and a client within which collections of statements grouped as batches are executed. A batch is either implicitly or explicitly mapped to one or several transactions. Is this correct?

  • PS/2 vs USB keyboards: performance and energy consumption

    - by Mister Smith
    As far as I know, PS/2 keyboards are interrupt driven, while USB are polled. Typically a PS/2 keyboard was assigned IRQ_1 on Windows. I'm no hardware expert, but at a first glance seems like the PS/2 keyboards are more efficient. So here are my questions: On modern day computers, are PS/2 keyboard better (or faster), and if so, would it be noticeable at all? (e.g.: in gaming) Since they don't need polling, do PS/2 keyboards save energy compared to USB? (notice I'm not talking only about the peripheral here, but about the overall computer energy consumption). In case PS/2 had any advantage over USB, would adding a PS/2 adapter to my USB keyboard make the device as good as an actual PS/2 keyboard? Conversely, would adding a USB adapter to a PS/2 make it as bad as a USB KB? Thanks in advance.

  • Windows Forms: Unable to Click to Focus a MaskedTextBox in a Non TopLevel Form

    - by Overhed
    Like the title says, I've got a Child form being shown with it's TopLevel property set to False and I am unable to click a MaskedTextBox control that it contains (in order to bring focus to it). I can bring focus to it by using TAB on the keyboard though. The child form contains other regular TextBox controls and these I can click to focus with no problems, although they also exhibit some odd behavior: for example if I've got a value in the Textbox and I try to drag-click from the end of the string to the beginning, nothing happens. In fact I can't use my mouse to move the cursor inside the TextBox's text at all (although they keyboard arrow keys work). I'm not too worried about the odd TextBox behavior, but why can't I activate my MaskedTextBox by clicking on it? Below is the code that shows the form: Dim newReportForm As New Form Dim formName As String Dim FullTypeName As String Dim FormInstanceType As Type formName = TreeView1.SelectedNode.Name FullTypeName = Application.ProductName & "." & formName FormInstanceType = Type.GetType(FullTypeName, True, True) newReportForm = CType(Activator.CreateInstance(FormInstanceType), Form) Try newReportForm.Top = CType(SplitContainer1.Panel2.Controls(0), Form).Top + 25 newReportForm.Left = CType(SplitContainer1.Panel2.Controls(0), Form).Left + 25 Catch End Try newReportForm.TopLevel = False newReportForm.Parent = SplitContainer1.Panel2 newReportForm.BringToFront() newReportForm.Show()

  • WS Libs: com.sun.xml vs javax.xml

    - by Zilvinas
    There are identical classes of java WebServices API & IMPL in those packages groups, only package names are different. http://mvnrepository.com/artifact/javax.xml http://mvnrepository.com/artifact/com.sun.xml Which ones should I use in my code? I would prefer NON-com.sun.* as per java conventions, but still my dependencies ( e.g. Spring ) are using implementations from com.sun.* OR I can't find an implementation package in javax.xml Does anyone have any experience on this?

  • Intel Pentium 4 vs. Faster Celeron

    - by Synetech inc.
    A few months ago my motherboard died, so I bought a used computer that had a 2.4GHz Celeron. My old system had a 1.7GHz Pentium 4, so now I’m trying to decide which CPU to use. Obviously a P4 is preferable over a Celeron, but the Celeron is (significantly?) faster than the P4. I’m wondering if the faster Celeron might be better for certain tasks (ie, stronger but dumber is better at some things than smarter but weaker). I tried Googling for some reviews and comparisons for graphs to get a clear depiction of which is better overall, but found nothing that helped. (I did manage to find one page that indicates (apparently by poll, not benchmark) that the Celeron is better.) So which CPU should I use? Does anyone know of some graphs that I can use to compare the two?

  • FTP Sites vs Sites in IIS 7.0

    - by NealWalters
    We have one FTP site set up (and working) basically like the instructions here: http://www.iis.net/learn/publish/using-the-ftp-service/creating-a-new-ftp-site-in-iis-7 It shows up under "Sites" and then the name of our FTP Site. However, above "Sites" (in the left navigation tree view), we see a node called "FTP Sites". When we click on it, it says "FTP Management is provided by IIS 6.0". Can someone give me the big picture of why this node appears, and why IIS 6 is involved? Is is some backward compatible feature? I didn't build these machines, so don't know the reasoning of what was done before I arrived on the scene. Also, is the tree view icon for websites and FTP sites the same?

  • AWS VPC ELB vs. Custom Load Balancing

    - by CP510
    So I'm wondering if this is a good idea. I have a Amazon AWS VPC setup with a public and private subnets. So I all ready get the Internet Gateway and NAT. I was going to setup all my web servers (Apache2 isntances) and DB servers in the private subnet and use a Load Balancer/Reverse Proxy to pick up requests and send them into the private subnets cluster of servers. My question then, is Amazons ELB's a good use for these, or is it better to setup my own custom instance to handle the public requests and run them through the NAT using nginx or pound? I like the second option just for the sake of having a instance I can log into and check. As well as taking advantage of caching and fail2ban ddos prevention, as well as possibly using fail safes to redirect traffic. But I have no experience with their ELB's, so I thought I'd ask your opinions. Also, if you guys have an opinion on this as well, would using the second option allow me to only have 1 public IP address and be able to route SSH connections through port numbers to respective instances? Thanks in advance!

  • Forefront TMG vs pfSense

    - by JD01
    Hi all, We currently run pfSense with no problems, however we are looking at TMG as it is included in our partner subscription to MS and allows Windows 7 DirectConnect features to our domain for off-site users. I have had a google, but there don't seem to be any comparisons of TMG to pfSense. Anyone have experience/knowledge of this? Our infrastructure is Windows Server 2008 R2 behind pfSense at the moment.

  • HP Laserjet "maintenance interval" vs "fuser life"

    - by marienbad
    I posted a question about the Laserjet 8100DN earlier here: http://serverfault.com/questions/139043/buying-an-old-laser-printer-what-will-need-to-be-replaced and from doing some more research I have a new question: I found the "maintence interval" -- "the interval at which you should install a maintenance kit" (which is a fuser and rollers), and it is...350,000 pages. BUT, when I look at the specs for an HP 8100 fuser, it says the fuser has a life span of 150,000 pages. What gives? – Will the fuser go bad after 150 or 350? ==== BTW I hope it's ok to ask another similar question in a new thread -- I'm just following instructions from my thread on the topic at Meta.

  • Reconciling vmware memory vs windows memory usage

    - by RyanW
    I have a Windows 2008 R2 64 bit virtual machine on ESXi 4.1 host. The host reports that the virtual machine is actively using less than 1 GB of memory. But, in Windows it's reporting the machine is using 7 GB of memory, even though the total of the processes listed in task manager is less than 1 GB. The machine is rather unresponsive and I'm concerned this is impacting other applications (server's purpose is to run ASP.NET state server process, which has been having trouble and led me to spot the memory question). I just noticed High memory usage Windows Server 2008r2 on VMware and will be looking through those documents more, but what is causing this?

  • Non-Standard widget size for Android

    - by heorling
    I have a use-case for a vertical 1x4 home screen widget on android. The supported size is 4x1 ie horizontal. Does anyone know if the vertical version can be implemented? I realize changing screen orientation would scrunch the widget together, which I'm fine with. Even better would be if there was an equivalent to "overflow hidden" in css. Has anyone come across a way to do this?
