  • Setup IIS 7.5 with multiple website bindings and SSL?

    - by JK01
    On IIS 7.5 I am trying to achieve this with two websites: Default Web Site is bound to: (blank host header port 80 - http) (blank host header port 443 - https) go.example.com www71.example.com the IP address of go.example.com 2nd web site "Beta" is bound to: beta.example.com (blank host header port 443 - https) * using blank only because it doesn't seem to be possible to bind https to a named host header And both need to work with SSL. But I have these problems: When I type in beta.example.com, I see the go.example.com site instead I can not seem to add the SSL binding to both websites at once (I have a single *.example.com wildcard certificate). The beta site will not even start if I add the https binding to it. This is how I have set it up: What is the correct way to set it up?

  • Job queueing in Toast Titanium 10?

    - by moonslug
    I have a bunch of .MP4 video files I'm burning to DVD-Video using Toast Titanium 10 on my MacBook Pro. Right now, I'm doing them one at a time. Because my computer is several years old, encoding video for a single DVD takes approximately six hours. I've discovered that it appears I can encode the video directly to a .toast format — however, I have yet to figure out if I can burn these directly to DVD. Also, I have quite a bit of video left to burn, and even that method would require me intervening manually to start a new encoding or burn job every six hours. Would it be possible to somehow queue up multiple DVD-Video encoding jobs at once, and have the computer work through them automatically? The actual writing to DVD disc doesn't take nearly as long, and if I had all my video encoded for me to begin with my job would be a lot quicker. Maybe this can be accomplished with a different piece of software?

  • HP Deskjet 3600: Offline and won't stop blinking and won't print.

    - by George Bailey
    Using Vista and an HP Deskjet 3600 on USB connection Normally when I unplug the printer, I open the printer queue and in the title bar it says "HP Deskjet 3600 - Use Printer Offline" then the offline message will go away and it will start printing. But for some reason, the bower button light is continually blinking. (this is the only light on the machine). The printer queue says "HP Deskjet 3600 - Offline" and when I unplug it it says "HP Deskjet 3600 - Offline - Use Printer Offline". I have tried unplugging it for a few hours, also tried turning it off for a few hours. Does anybody know what the single word Offline means? Does anybody know how I can clear out the memory in the Printer? (this is my guess as to what is causing the problem)

  • MS-Outlook add-on to move a new message to the same folder as the rest of the thread

    - by Guss
    I'm forced to use MS-Outlook in my job, while I very much like the feature that shows all the messages of a discussion thread (that are stored in different folders) in the inbox when a new message is received for that thread, if the previous messages are in a different data file (which I'm forced to have as the MS-Exchange server quota is very very small) then the message list only shows the name of the data file and not the name of the folder where the messages are stored. As a result, because I file my message by context (i.e. all the emails for project A go into a "Project A" folder, etc), and its important for me to have all the messages in a single thread in the same folder, it is sometimes hard to figure out into which folder should I file the new message. It would be great help if there was some add-on or VBA script that I could add to my setup that will offer a shortcut key or a button to "file this message to the same folder as the previous messages in the conversation thread".

  • What hardware factors may be considered bottlenecks on a Hyper-V virtual server during load testing?

    - by sean
    Our organization is load testing our application using virtual servers via Hyper-V to see what the user load can be using fair equipment on a single box setup. The developer group questioned the validity of the tests given the normal use of the box by the other virtual machines. IT admins answered that it is an acceptable platform to load test on because it has its own CPUs, memory and disks allocated. Is their answer mostly correct? What hardware factors may be considered bottle necks given the other virtual machines when testing our application? For example, would bus speed be a concern or network IO? The application consists of a windows service written using the 4.0 .NET Framework and SQL Server 2008 R2.

  • Disable ALTQ for internal network traffic

    - by javanix
    I currently have a FreeBSD 8.2 media server set up on my LAN that I use to stream my music from. I also have an SSH login that I use to do file transfers to and from this server remotely. I would like to set up ALTQ (and have gotten this working) to limit my outgoing bandwidth from the server for SSH traffic. However, configuring ALTQ this way is also limiting my internal traffic (and thus interfering with my music streaming) since I am only using a single network interface. Can anyone show me how I would use PF and ALTQ to limit outgoing WAN traffic while allowing all internal LAN traffic to go through unhindered? ext_if="eth0" int_if="eth0" altq on eth0 cbq bandwidth 1Mb queue { std, ssh } queue std bandwidth 80% cbq(default) queue ssh bandwidth 20% cbq(ecn) pass out on eth0 proto tcp to port 22 queue ssh eth0 is my LAN interface, my total WAN bandwidth on my cable connection is 1Mb/s, and my internal network is 10/100.

  • No MAU required on a T4

    - by jsavit
    Cryptic background One of the powerful features of the T-series servers is its hardware crypto acceleration, which dramatically speeds up the compute intensive algorithms needed to encrypt and decrypt data. Previously, administrators setting up logical domains on older T-series servers had to explicitly assign crypto resources (called "MAU" for historical reasons from the T1 chip that had "modular arithmetic units") to domains that had a significant crypto workload (say, an SSL based web server). This could be an administrative burden, as you had to choose which domains got the crypto units, and issue the appropriate ldm set-mau N mydomain commands. The T4 changes things The T4 is fast. Really fast. Its clock rate and out-of-order (OOO) execution that provides the single-thread performance that T-series machines previously did not have. If you have any preconceptions about T-series performance, or SPARC in general, based on the older servers (which, it must be said, were absolutely outstanding for multi-threaded applications), those assumptions are now obsolete. The T4 provides outstanding. performance for all kinds of workload, as illustrated at https://blogs.oracle.com/bestperf. While we all focused on this (did I mention the T4 is fast?), another feature of the T4 went largely unnoticed: The T4 servers have crypto acceleration "just built in" so administrators no longer have to assign crypto accelerator units to domains - it "just happens". This is way way better since you have crypto everywhere by default without having to manage it like a discrete and limited resource. It's a feature of the processor, like doing an integer add. With T4, there is no management necessary, you just have HW crypto everywhere all the time seamlessly. This change hasn't been widely advertised, and some administrators have wondered why there were unable to assign a MAU to a domain as they did with T2 and T3 machines. The answer is that there is no longer any separate MAU, so you don't have to take any action at all - just leave the default of 0. Summary Besides being much faster than its predecessors, the T4 also integrates hardware crypto acceleration so its seamlessly available to applications, whether domains are being used or not. Administrators no longer have to control how they are allocated - it "just happens"

  • How to get a list of all software that starts automatically when Windows 7 starts?

    - by hippietrail
    I know that under Windows there are multiple ways to get an app to autostart but I can never remember what all of those ways are. Is there a single unified way to bring up a list of all programs which are set to run themselves at startup and let me disable those I don't want? I'd prefer something built into Windows. I have Windows 7 Starter. But a free / open source / shareware tool would also be acceptable. (This time the software I want to prevent from autostarting is: MSN Messenger, Y! Messenger, and Vodaphone Mobile Broadband, which starts whether the dongle is inserted or not. None of these three are in Windows's "Startup" folder.)

  • SSH reverse tunnel to monitor and manage remote devices

    - by acid_crucifix
    I have a set a distributed set of devices running Ubuntu 12.04 that I am distributing to clients. I would like to manage them remotely. They may not have fixed IPs and potentially might be behind firewalls. What I am planning to do is have the devices (permanently connected to the net) poll a request URL and based on the response open a reverse tunnel to my server, so that I can access them via that tunnel. Most of what I read about reverse tunnel over SSH is for single use cases and very little about heavy production usage. Is there some reason for this, security issues? or stability? Any help would be much obliged.

  • What is an appropriate language for expressing initial stages of algorithm refinement?

    - by hydroparadise
    First, this is not a homework assignment, but you can treat it as such ;). I found the following question in the published paper The Camel Has Two Humps. I was not a CS major going to college (I majored in MIS/Management), but I have a job where I find myself coding quite often. For a non-trivial programming problem, which one of the following is an appropriate language for expressing the initial stages of algorithm refinement? (a) A high-level programming language. (b) English. (c) Byte code. (d) The native machine code for the processor on which the program will run. (e) Structured English (pseudocode). What I do know is that you usually want to start your design implementation by writing down pseuducode and then moving/writing in the desired technology (because we all do that, right?) But I never thought about it in terms of refinement. I mean, if you were the original designer, then you might have access to the original pseudocode. But realisticly, when I have to maintain/refactor/refine somebody elses code, I just keep trucking with the language it currently resides in. Anybody have a definitive answer to this? As a side note, I did a quick scan of the paper as I havn't read every single detail. It presents various score statistics, can't find where the answers are with the paper.

  • Is it effective installing firewall within same machine which offering service?

    - by Eonil
    I'm a starting a small service practically. And I have single server currently. No money to purchase separated/dedicated firewall equipment now. Is it effective installing firewall software on same machine which offering internet service? My server will offer HTTP, NFS, and SSH, and custom made server software on a several ports. (edit) All services (except NFS) should be open to internet. Not internal services. I guess my machine (virtualized within Xen) is connected to the internet directly because I can connect to my machine SSH with only IP address. (edit) NFS is not open to internet. Sorry for my mistake. NFS will be served via SSH only.

  • Managing many draw calls for dynamic objects

    - by codetiger
    We are developing a game (cross-platform) using Irrlicht. The game has many (around 200 - 500) dynamic objects flying around during the game. Most of these objects are static mesh and build from 20 - 50 unique Meshes. We created seperate scenenodes for each object and referring its mesh instance. But the output was very much unexpected. Menu screen: (150 tris - Just to show you the full speed rendering performance of 2 test computers) a) NVidia Quadro FX 3800 with 1GB: 1600 FPS DirectX and 2600 FPS on OpenGL b) Mac Mini with Geforce 9400M 256mb: 260 FPS in OpenGL Now inside the game in a test level: (160 dynamic objects counting around 10K tris): a) NVidia Quadro FX 3800 with 1GB: 45 FPS DirectX and 50 FPS on OpenGL b) Mac Mini with Geforce 9400M 256mb: 45 FPS in OpenGL Obviously we don't have the option of mesh batch rendering as most of the objects are dynamic. And the one big static terrain is already in single mesh buffer. To add more information, we use one 2048 png for texture for most of the dynamic objects. And our collision detection hardly and other calculations hardly make any impact on FPS. So we understood its the draw calls we make that eats up all FPS. Is there a way we can optimize the rendering, or are we missing something?

  • How to represent a graph with multiple edges allowed between nodes and edges that can selectively disappear

    - by Pops
    I'm trying to figure out what sort of data structure to use for modeling some hypothetical, idealized network usage. In my scenario, a number of users who are hostile to each other are all trying to form networks of computers where all potential connections are known. The computers that one user needs to connect may not be the same as the ones another user needs to connect, though; user 1 might need to connect computers A, B and D while user 2 might need to connect computers B, C and E. Image generated with the help of NCTM Graph Creator I think the core of this is going to be an undirected cyclic graph, with nodes representing computers and edges representing Ethernet cables. However, due to the nature of the scenario, there are a few uncommon features that rule out adjacency lists and adjacency matrices (at least, without non-trivial modifications): edges can become restricted-use; that is, if one user acquires a given network connection, no other user may use that connection in the example, the green user cannot possibly connect to computer A, but the red user has connected B to E despite not having a direct link between them in some cases, a given pair of nodes will be connected by more than one edge in the example, there are two independent cables running from D to E, so the green and blue users were both able to connect those machines directly; however, red can no longer make such a connection if two computers are connected by more than one cable, each user may own no more than one of those cables I'll need to do several operations on this graph, such as: determining whether any particular pair of computers is connected for a given user identifying the optimal path for a given user to connect target computers identifying the highest-latency computer connection for a given user (i.e. longest path without branching) My first thought was to simply create a collection of all of the edges, but that's terrible for searching. The best thing I can think to do now is to modify an adjacency list so that each item in the list contains not only the edge length but also its cost and current owner. Is this a sensible approach? Assuming space is not a concern, would it be reasonable to create multiple copies of the graph (one for each user) rather than a single graph?

  • Lustre - is this bad form?

    - by ethrbunny
    Im going to be consolidating several 'server rooms' into a single installation soon. Part of this effort will be finding a home for 5Tb (and growing) of files / logs. To this end Im looking at Lustre and appreciating its ability to scale. The big vendors want to sell me a $20K SAN to manage this but Im wondering about buying several iSCSI units (like this http://www.asacomputers.com/3U-iSCSI-Solution.html) and using VMs for the OSS machines. This would let me fail-over to cover problems and not require a dedicated system for each OSS. Given articles like this (http://h30565.www3.hp.com/t5/Feature-Articles/RAID-Is-Dead-Long-Live-RAID/ba-p/1422) that talk about how RAID is not keeping up with drive density Im leaning towards more disks with lower capacity each. Again - some akin to the iSCSI array above. Tell me why this is a terrible idea. Do I really need to invest in a PE710 for each OSS/OST?

  • Why not commit unresolved changes?

    - by Explosion Pills
    In a traditional VCS, I can understand why you would not commit unresolved files because you could break the build. However, I don't understand why you shouldn't commit unresolved files in a DVCS (some of them will actually prevent you from committing the files). Instead, I think that your repository should be locked from pushing and pulling, but not committing. Being able to commit during the merging process has several advantages (as I see it): The actual merge changes are in history. If the merge was very large, you could make periodic commits. If you made a mistake, it would be much easier to roll back (without having to redo the entire merge). The files could remain flagged as unresolved until they were marked as resolved. This would prevent pushing/pulling. You could also potentially have a set of changesets act as the merge instead of just a single one. This would allow you to still use tools such as git rerere. So why is committing with unresolved files frowned upon/prevented? Is there any reason other than tradition?

  • Allowing outbound traffic with APF/iptables for OpenVZ container

    - by David
    I have apf installed on a OpenVZ container (proxmox 2.1). The config is pretty much vanilla and things are working. My external services like ssh and http are working. My problem is that all outbound traffic on http/https is blocked. How do I allow all outbound traffic for http/https. If I change EGF to 1 like this, all inbound and outbound traffic gets blocked EGF="1" EG_TCP_CPORTS="21,25,80,443,43,53" EG_UDP_CPORTS="20,21,53" EG_ICMP_TYPES="all" I opened a single outbound rule with the following # /usr/local/sbin/apf -a downloads.wordpress.org How do I allow all outbound traffic on http/https without blocking all traffic? Why would I allow all inbound ssh/http traffic and block all outbound traffic?

  • Lenovo ThinkServer TS130 1105 - does 32/64 depend on RAM?

    - by Ecnerwal
    Just got in a Lenovo ThinkServer TS130 1105 (Xeon E3-1225V1) and a (new, sealed, holographed, looks legit) copy of Windows Server 2008 32/64 (standard) to run on it for a pretty lightweight job (currently handled, adequately, by a terrifyingly old Optima P4 running Windows 2000 server - really lightweight, but long-past-due for replacement, without any particular need or excuse for server 2012...) The 64 bit disc sits there and does nothing. The 32 bit disc boots. I haven't spotted any mention of this in the TS130 Manual (I have now combed it, and find no mention of a need to populate in pairs - a preferred order to populate in, yes, but no mention of pairs being required) but I begin to wonder if it's due to the fact that the 4GB RAM suppled with it was a single DIMM, rather than a pair. Better for upgrading, but perhaps requiring an upgrade (or sidegrade) right away to install the x64 version?? Anyone know? I tried the 64-bit DVD on a desktop with an AMD Athlon II X4 635 processor which normally runs Windows7 in 64 bit, and it booted up just fine.

  • solaris + EMC + power-path

    - by yael
    please advice - when I run powercf command on my Solaris machine , which changes this command do on the EMC storage , or on Solaris file system ? from maanual page: DESCRIPTION During system boot on Solaris hosts, the powercf utility configures PowerPath devices by scanning the HBAs for both single-ported and multiported storage system logical dev- ices. (A multiported logical device shows up on two or more HBAs with the same storage system subsystem/device identity. The identity comes from the serial number for the logical device.) For each storage system logical device found in the scan of the HBAs, powercf creates a corresponding emcpower device entry in the emcp.conf file, and it saves a primary path and an alternate primary path to that device.

  • Why are my downloads up to ~1500KByte/sec only, when the ADSL connection locks at 13611Kbit/s?

    - by leladax
    No uploading is going on other than the overhead of downloading which appears to be not high for the abilities of the connection: Only about 30-40KByte/s when the router locks at 1012Kb/s and other direct uploads or uploading overheads can reach more than 100KByte/sec so I don't think it's a congestion at uploading that is doing it. Is there something I miss? Because I assume 13611Kbit/s should be ~1701Kbyte/sec. Is it an overheard at the ADSL level I don't understand? Could it be the ISP doing it? If it's active throttling it can't be on single connections since 2 high speed connections still go up to ~1500KByte/sec. It's not an example on torrents or other complex situations. The tests were on Ethernet, but I doubt the results would be different on wireless. I wonder if the settings of those connections at my end could be doing it, e.g. MTU settings, though I haven't touched the defaults of a common Realtek NIC.

  • MVC pattern synchronisation

    - by Hariprasad
    I am facing a problem in synchronizing my model and view threads I have a view which is table. In it, user can select a few rows. I update the view as soon as the user clicks on any row since I don't want the UI to be slow. This updating is done by a logic which runs in the controller thread below. At the same time, the controller will update the model data too, which takes place in a different thread. i.e., controller puts the query in a queue, which is then executed by the model thread - which is a single-threaded interface. As soon as the query executes, controller will get a signal. Now, In order to keep the view and model synchronized, I will update the view again based on the return value of the query (the data returned by model) - even though I updated the view already for that user action. But, I am facing issues because, its taking a lot of time for the model to return the result, by that time user would have performed multiple clicks. So, as a result of updating the view again based on the information from model, the view sometimes goes back to the state in which the previous clicks were made (Suppose user clicks thrice on different rows. I update the view as soon as the click happens. Also, I update the view when I get data back from the model - which is supposed to be same as the already updated state of the view. Now, when the user clicks third time, I get data for the first click from model. As a result, view goes back to a state which is generated by the first click) Is there any way to handle such a synchronization issue?

  • What are the Windows G: through Z: drives used for?

    - by Tom Wijsman
    In Windows you have a C: drive. The first things labeled beyond that seems to be extra stuff. So my DVD drive is D: and if you put in a USB stick it becomes F:. And then some people also have A: and B:. But then, what and where are G: through Z: drives for? Is it possible to connect so many things to a computer to make them all in use? Or more than them? Would it give a BSOD? Or would this slow down the system somehow? Or what would happen? What if I want to connect even more drives to the computer? Because with the hard drive limits it's more efficient to buy more drives than to buy a single drive with a lot of capacity. Is it possible to create drive letters like 0: through Z: or AA: through ZZ:?

  • Strategies for avoiding SQL in your Controllers... or how many methods should I have in my Models?

    - by Keith Palmer
    So a situation I run into reasonably often is one where my models start to either: Grow into monsters with tons and tons of methods OR Allow you to pass pieces of SQL to them, so that they are flexible enough to not require a million different methods For example, say we have a "widget" model. We start with some basic methods: get($id) insert($record) update($id, $record) delete($id) getList() // get a list of Widgets That's all fine and dandy, but then we need some reporting: listCreatedBetween($start_date, $end_date) listPurchasedBetween($start_date, $end_date) listOfPending() And then the reporting starts to get complex: listPendingCreatedBetween($start_date, $end_date) listForCustomer($customer_id) listPendingCreatedBetweenForCustomer($customer_id, $start_date, $end_date) You can see where this is growing... eventually we have so many specific query requirements that I either need to implement tons and tons of methods, or some sort of "query" object that I can pass to a single -query(query $query) method... ... or just bite the bullet, and start doing something like this: list = MyModel-query(" start_date X AND end_date < Y AND pending = 1 AND customer_id = Z ") There's a certain appeal to just having one method like that instead of 50 million other more specific methods... but it feels "wrong" sometimes to stuff a pile of what's basically SQL into the controller. Is there a "right" way to handle situations like this? Does it seem acceptable to be stuffing queries like that into a generic -query() method? Are there better strategies?

  • Practical way to set up an email inbox for testing?

    - by Ben Collins
    I need to test a high-volume email application. Up to now, I've just been using gmail ad-hoc aliases ([email protected]) to receive emails and see that the content is right. However, I now need to verify a recipient list, which means I need to get every single email that goes out on a particular test run. The problem with Google isn't clear, but there's some throttling somewhere (perhaps from SendGrid, who is my delivery provider), and only a very small number of those emails ever make it to my acount. So: what's a practical way to get where I want to be? Is there a way to get gmail to just accept everything? Is there a web app / service somewhere that will let me throw up a fake email address that can receive for a large number of recipients? Is there something else?

  • Pure functional programming and game state

    - by Fu86
    Is there a common technique to handle state (in general) in a functional programming language? There are solutions in every (functional) programming language to handle global state, but I want to avoid this as far as I could. All state in a pure functional manner are function parameters. So I need to put the whole game state (a gigantic hashmap with the world, players, positions, score, assets, enemies, ...)) as a parameter to all functions which wants to manipulate the world on a given input or trigger. The function itself picks the relevant information from the gamestate blob, do something with it, manipulate the gamestate and return the gamestate. But this looks like a poor mans solution for the problem. If I put the whole gamestate into all functions, there is no benefit for me in contrast to global variables or the imperative approach. I could put just the relevant information into the functions and return the actions which will be taken for the given input. And one single function apply all the actions to the gamestate. But most functions need a lot of "relevant" information. move() need the object position, the velocity, the map for collision, position of all enemys, current health, ... So this approach does not seem to work either. So my question is how do I handle the massive amount of state in a functional programming language -- especially for game development?

  • Set 802.1Q tagged port on VLAN1 on Dell PowerConnect switch

    - by Javier
    I'm having big troubles when adding this Dell switch to my network. Here we use several VLANs to segment traffic. All switches (3com and DLink mostly) have configured the same VLANs, most ports are 'untagged' and belong to a single VLAN, except for the ports used to join together the switches (in a star topology), these ports belong to all VLANs and use 802.1Q tags. So far, it works really well. But on this new switch (a Dell PowerConnect 5448), the settings are very different (and confusing). I have configured the same VLANs, an the uplink ports are set in 'general' mode (supposed to be fully 802.1Q compliant), I can set the VLAN membership as 'T' on these ports for all VLANs except VLAN 1. It always stay as 'U' on VLAN 1. Any ideas?
