• Messages stuck in SMTP queue - Exchange 2003

  - by Diav

  I need your help people ;-) I have a problem with messages coming into our Exchange Server and ones going out through it. Basically, the messages are stuck in the SMTP queue. A message will come into the server, I can see it listed under "Exchange System Manager", but if you list the properties of the message queue it says something like 00:10 SMTP Message queued for local delivery 00:10 SMTP Message delivered locally to [email protected] 00:10 SMTP Message scheduled to retry local delivery 00:11 SMTP Message delivered locally to [email protected] 00:11 SMTP Message scheduled to retry local delivery etc etc For outgoing message list looks like this: 10:55 SMTP: Message Submitted to Advanced Queuing 10:55 SMTP: Started Message Submission to Advanced Queue 10:55 SMTP: Message Submitted to Categorizer 10:55 SMTP: Message Categorized and Queued for Routing 10:55 SMTP: Message Routed nad Queued for Remote Delivery And the end - since then status didn't change, message is in queue, I am forcing connection from time to time but without an effect. I checked connection with smarthost (used telnet for that) and everything seems to work correctly, so the problem is probably on exchange side. I am using Exchange Server 2003 running on Small Business Server 2003. I don't have any antivirus installed on server. Remaining free space on each partition is over 3Gb, on partition with data bases - it is over 12Gb. All was working good and without problems since 2005, problems started in half of this june - messages started going out and being stuck almost randomly (I don't see a pattern yet, some are going out, some are not, some are going after several hours). I don't know what to do, what to check more, so please, any ideas? Best regards, D. edit Priv1.edb has 14,5GB and priv1.stm 2,6GB - together those files have more than 16GB - can it be the reason? If yes, then what? Indeed, I haven't thought that it can have something in common with my problem, but several users reported recent problems with Outlook Web Access - they can log in, they see the list of their mails, but they can't see the content of their emails. Although when they are connecting with Outlook 2003/2007 - there is no such problem, only with OWA there is. edit2 So,.. It works now, and I have to admit that I am not really sure what the problem was (hope it won't come back). What have I done: Cleaned up some mailboxes to reduce size of them Dismounted Information Store Defragmentated data base files ( I used eseutil: c:\program files\exchsrvr\bin eseutil /d g:\data base\Exchsrvr\MDBDATA\priv1.edb ) Mounted Information Store back ..and before I managed to do anything else - my queue started moving, elements which were kept there already for days - started moving and after few minutes everything was sent, both, outside and locally. But: priv1.edb is still big (13 884 203 008), priv1.stm as well (2 447 384 576), so this is probably not the issue of size of the file. And if not this, so what was that? And if that was issue of size of the file, then soon it will repeat - is there something I can do to avoid it ?

• How to backup database dumps which only minor changes between the backups?

  - by wurlog

  I have a mysql dumpfile every night and i every one of them. Each is 14 GB in size, so my backupdrive will be full soon. The difference from one day to another are only some 100MB. How make the daily backups without wasting a lot of space. PS: i used tar to compress 1 file and the size went down to 5GB. I hoped that when i compress two files the ratio would be better, but no. 2 dumps compressed are 10Gb

• How to switch sound-drivers, and to which? [AMD] Hudson Azalia Controller

  - by Anders Martini

  System settings/sound does not open, freezes and I have to force close. Speaker symbol with volume control does not open scroll-down menu, and there is no sounds. Many people have problems with Hudson Azalia in Ubuntu, but I found no working solution. I don't really understand much of this, but here are some more details: aplay -l : **** List of PLAYBACK Hardware Devices **** (after running this one, it starts some kind of process that doesn't get any results, and doesn't stop, terminal has to be shut down) lspci -vnn | grep -iA5 audio: 00:01.1 Audio device [0403]: Advanced Micro Devices [AMD] nee ATI Device [1002:9902] Subsystem: Hewlett-Packard Company Device [103c:184c] Flags: bus master, fast devsel, latency 0, IRQ 53 Memory at f0444000 (32-bit, non-prefetchable) [size=16K] Capabilities: <access denied> Kernel driver in use: snd_hda_intel -- 00:14.2 Audio device [0403]: Advanced Micro Devices [AMD] Hudson Azalia Controller [1022:780d] (rev 01) Subsystem: Hewlett-Packard Company Device [103c:184c] Flags: bus master, slow devsel, latency 32, IRQ 54 Memory at f0440000 (64-bit, non-prefetchable) [size=16K] Capabilities: <access denied> Kernel driver in use: snd_hda_intel It seems to me that I'm currently running hda Intel drivers on my AMD Hudson Azalia soundcard.

• Monogame - Shader parameters missing

  - by Layoric

  I am currently working on a simple game that I am building in Windows 8 using MonoGame (develop3d). I am using some shader code from a tutorial (made by Charles Humphrey) and having an issue populating a 'texture' parameter. I'm not well versed writing shaders, so this might be caused by a more obvious problem. I have debugged through MonoGame's Content processor to see how this shader is being parsed, all the non 'texture' parameters are there and look to be loading correctly. Shader code below #include "PPVertexShader.fxh" float2 lightScreenPosition; float4x4 matVP; float2 halfPixel; float SunSize; texture flare; sampler2D Scene: register(s0){ AddressU = Clamp; AddressV = Clamp; }; sampler Flare = sampler_state { Texture = (flare); AddressU = CLAMP; AddressV = CLAMP; }; float4 LightSourceMaskPS(float2 texCoord : TEXCOORD0 ) : COLOR0 { texCoord -= halfPixel; // Get the scene float4 col = 0; // Find the suns position in the world and map it to the screen space. float2 coord; float size = SunSize / 1; float2 center = lightScreenPosition; coord = .5 - (texCoord - center) / size * .5; col += (pow(tex2D(Flare,coord),2) * 1) * 2; return col * tex2D(Scene,texCoord); } technique LightSourceMask { pass p0 { VertexShader = compile vs_4_0 VertexShaderFunction(); PixelShader = compile ps_4_0 LightSourceMaskPS(); } } I've removed default values as they are currently not support in MonoGame and also changed ps and vs to v4 instead of 2. Could this be causing the issue? As I debug through 'DXConstantBufferData' constructor (from within the MonoGameContentProcessing project) I find that the 'flare' parameter does not exist. All others seem to be getting created fine. Any help would be appreciated.

• Perpendicularity of a normal and a velocity?

  - by Milo

  I'm trying to fake angular velocity on my vehicle when it hits a wall by getting the dot product of the normal of the edge the car is hitting and the vehicle's velocity: Vector2D normVel = new Vector2D(); normVel.equals(vehicle.getVelocity()); normVel.normalize(); float dot = normVel.dot(outNorm); dot = -dot; vehicle.setAngularVelocity(vehicle.getAngularVelocity() + (dot * vehicle.getVelocity().length() * 0.01f)); outNorm is the normal of the wall. The problem is it only works half the time. It seems no matter what, the car always goes clockwise. If the car should head clockwise: -------------------------------------- / / I want the angular velocity to be positive, otherwise if it needs to go CCW: -------------------------------------- \ \ Then the angular velocity should be negative... What should I change to achieve this? Thanks Hmmm... Im not sure why this is not working... for(int i = 0; i < buildings.size(); ++i) { e = buildings.get(i); ArrayList<Vector2D> colPts = vehicle.getRect().getCollsionPoints(e.getRect()); float dist = OBB2D.collisionResponse(vehicle.getRect(), e.getRect(), outNorm); for(int u = 0; u < colPts.size(); ++u) { Vector2D p = colPts.get(u).subtract(vehicle.getRect().getCenter()); vehicle.setTorque(vehicle.getTorque() + p.cross(outNorm)); }

• ZFS: Redistribute zvol over all disks in the zpool?

  - by growse

  Is there a way in which ZFS can be prompted to redistribute a given filesystem over the all of the disks in its zpool? I'm thinking of a scenario where I have a fixed size ZFS volume that's exported as a LUN over FC. The current zpool is small, just two 1TB mirrored disks, and the zvol is 750GB in total. If I were to suddenly expand the size of the zpool to, say, 12 1TB disks, I believe the zvol would still effectively be 'housed' on the first two spindles only. Given that more spindles = more IOPS, what method could I use to 'redistribute' the zvol over all 12 spindles to take advantage of them?

• How do partitions help in optimizing the harddrive?

  - by Fasih Khatib

  I was recently reading a guide on Tom's Hardware about how to optimize the harddrive. They listed creating partitions as one of them. They said keeping the various files seperate is a good idea as it reduces the read/write cycles required. Now my querry is: what size partitions do i make for my 500gb harddrive. Its completely blank. I will be installing WIN7 in it. My usual strategy is to divide it into two equal partitions. Is it the optimum size?

  I have a mysql database on a server that is around 4 gb in size and I couldn't get it downloaded to my local machine. I tried getting a dump on the server, but the dump is not getting created probably because of the big size. Is there any way, I could get the dump downloaded on my local machine? I can syncing using Sqlyog but I know it will take ages. Is there a way, I can get a dump created on the server? By the way, my server is a linux server and its running php/mysql.

As an industry, we’ve spent many years analyzing all the data that’s been collected. Yes, that data has been invaluable in helping us make better decisions like where to open new stores, how to assort those stores, and how to price our products. But the recent advances in technology are now making it possible to analyze and deliver that data very quickly… fast enough to impact a potential sale in near real-time. Let me give you two examples. Salesmen in car dealerships get pretty good at sizing people up. When a potential customer walks in the door, it doesn’t take long for the salesman to figure out the revenue at stake. Is this person a real buyer, or just looking for a fun test drive? Will this person buy today or three months from now? Will this person opt for the expensive packages, or go bare bones? While the salesman certainly asks some leading questions, much of information is discerned through body language. But body language doesn’t translate very well over the web. Eloqua, which was acquired by Oracle earlier this year, reads internet body language. By tracking the behavior of the people visiting your web site, Eloqua categorizes visitors based on their propensity to buy. While Eloqua’s roots have been in B2B, we’ve been looking at leveraging the technology with ATG to target B2C. Knowing what sites were previously visited, how often the customer has been to your site recently, and how long they’ve spent searching can help understand where the customer is in their purchase journey. And knowing that bit of information may be enough to help close the deal with a real-time offer, follow-up email, or online customer service pop-up. This isn’t so different from the days gone by when the clerk behind the counter of the corner store noticed you were lingering in a particular aisle, so he walked over to help you compare two products and close the sale. You appreciated the personalized service, and he knew the value of the long-term relationship. Move that same concept into the digital world and you have Oracle’s CX Suite, a cloud-based offering of end-to-end customer experience tools, assembled primarily from acquisitions. Those tools are Oracle Marketing (Eloqua), Oracle Commerce (ATG, Endeca), Oracle Sales (Oracle CRM On Demand), Oracle Service (RightNow), Oracle Social (Collective Intellect, Vitrue, Involver), and Oracle Content (Fatwire). We are providing the glue that binds the CIO and CMO together to unleash synergies that drive the top-line higher, and by virtue of the cloud-approach, keep costs at bay. My second example of real-time marketing takes place in the store but leverages the concepts of Web marketing. In 1962 the decline of personalized service in retail began. Anyone know the significance of that year? That’s when Target, K-Mart, and Walmart each opened their first stores, and over the succeeding years the industry chose scale over personal service. No longer were you known as “Jane with the snotty kid so make sure we check her out fast,” but you suddenly became “time-starved female age 20-30 with kids.” I’m not saying that was a bad thing – it was the right thing for our industry at the time, and it enabled a huge amount of growth, cheaper prices, and more variety of products. But scale alone is no longer good enough. Today’s sophisticated consumer demands scale, experience, and personal attention. To some extent we’ve delivered that on websites via the magic of cookies, your willingness to log in, and sophisticated data analytics. What store manager wouldn’t love a report detailing all the visitors to his store, where they came from, and which products that examined? People trackers are getting more sophisticated, incorporating infrared, video analytics, and even face recognition. (Next time you walk in front on a mannequin, don’t be surprised if it’s looking back.) But the ultimate marketing conduit is the mobile phone. Since each mobile phone emits a unique number on WiFi networks, it becomes the cookie of the physical world. Assuming congress keeps privacy safeguards reasonable, we’ll have a win-win situation for both retailers and consumers. Retailers get to know more about the consumer’s purchase journey, and consumers get higher levels of service with the retailer. When I call my bank, a couple things happen before the call is connected. A reverse look-up on my phone number identifies me so my accounts can be retrieved from Siebel CRM. Then the system anticipates why I’m calling based on recent transactions. In this example, it sees that I was just charged a foreign currency fee, so it assumes that’s the reason I’m calling. It puts all the relevant information on the customer service rep’s screen as it connects the call. When I complain about the fee, the rep immediately sees I’m a great customer and I travel lots, so she suggests switching me to their traveler’s card that doesn’t have foreign transaction fees. That technology is powered by a product called Oracle Real-Time Decisions, a rules engine built to execute very quickly, basically in the time it takes the phone to ring once. So let’s combine the power of that product with our new-found mobile cookie and provide contextual customer interactions in real-time. Our first opportunity comes when a customer crosses a pre-defined geo-fence, typically a boundary around the store. Context is the key to our interaction: that’s the customer (known or anonymous), the time of day and day of week, and location. Thomas near the downtown store on a Wednesday at noon means he’s heading to lunch. If he were near the mall location on a Saturday morning, that’s a completely different context. But on his way to lunch, we’ll let Thomas know that we’ve got a new shipment of ASICS running shoes on display with a simple text message. We used the context to look-up Thomas’ past purchases and understood he was an avid runner. We used the fact that this was lunchtime to select the type of message, in this case an informational message instead of an offer. Thomas enters the store, phone in hand, and walks to the shoe department. He scans one of the new ASICS shoes using the convenient QR Codes we provided on the shelf-tags, but then he starts scanning low-end Nikes. Each scan is another opportunity to both learn from Thomas and potentially interact via another message. Since he historically buys low-end Nikes and keeps scanning them, he’s likely falling back into his old ways. Our marketing rules are currently set to move loyal customer to higher margin products. We could have set the dials to increase visit frequency, move overstocked items, increase basket size, or many other settings, but today we are trying to move Thomas to higher-margin products. We send Thomas another text message, this time it’s a personalized offer for 10% off ASICS good for 24 hours. Offering him a discount on Nikes would be throwing margin away since he buys those anyway. We are using our marketing dollars to change behavior that increases the long-term value of Thomas. He decides to buy the ASICS and scans the discount code on his phone at checkout. Checkout is yet another opportunity to interact with Thomas, so the transaction is sent back to Oracle RTD for evaluation. Since Thomas didn’t buy anything with the shoes, we’ll print a bounce-back coupon on the receipt offering 30% off ASICS socks if he returns within seven days. We have successfully started moving Thomas from low-margin to high-margin products. In both of these marketing scenarios, we are able to leverage data in near real-time to decide how best to interact with the customer and lead to an increase in the lifetime value of the customer. The key here is acting at the moment the customer shows interest using the context of the situation. We aren’t pushing random products at haphazard times. We are tailoring the marketing to be very specific to this customer, and it’s the technology that allows this to happen in near real-time. Conclusion As we enable more right-time integrations and interactions, retailers will begin to offer increased service to their customers. Localized and personalized service at scale will drive loyalty and lead to meaningful revenue growth for the retailers that execute well.

• Restoring a Ubuntu Linux LVM drive

  - by user848106

  Scenario: I have a hard disk with a bootable sda1 partition and an Linux LVM. I seem to have corrupted the MBR? or Grub? not sure. I know it no longer boots and even with boot-repair and a Ubuntu live usb I was able to restore it. Following a "fix" with boot-repair I get "missing operating system" Can't i just reinstall grub or a new menu.lst? Disk /dev/sda: 320.1 GB, 320072933376 bytes 255 heads, 63 sectors/track, 38913 cylinders, total 625142448 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x0007b68f Device Boot Start End Blocks Id System /dev/sda1 * 2048 499711 248832 83 Linux /dev/sda2 501758 625141759 312320001 5 Extended /dev/sda5 501760 625141759 312320000 8e Linux LVM

• Partial-stroking / Short-stroking / Half-stroking Hard Drives?

  - by Daniel Magliola

  Could anyone here explain to me what is implied by this term? (I've seen the same thing mentioned with the 3 terms). At first when I read about it, for some reason I understood that it was some way of splitting the bytes across the platters of the disk, which sounded like a good idea and obviously doesn't make sense, because that wouldn't cut disk size in half (and disk are probably already splitting bytes across platters)... The best I've come to understand is that basically instead of creating one partition for the whole size of the disk, you create 2 partitions, and use only one of them, either the one in the "center" or the one in the "rim" of the platters, and since one of the two is faster (people didn't seem to agree on which one was faster), that makes everything better. Am I understanding this correctly? Has anyone tried this with their drives and had a good outcome? Thanks!

  Related to this question How do I run qemu with 64bit processor on a 64bit machine?, I'm trying to run latest ubuntu 11.10 64bit distribution under Ubuntu 11.04 32 bit using qemu on a core2duo (64 bit cpu) machine, using following qemu parameters with no success.

  I have Debian server with 32 gb memory. And there is apache2, memcached and nginx on this server. Memory load always on maximum. Only 500m free. Most memory leak do MySql. Apache only 70 clients configured, other services small memory usage. When mysql use all memory it stops. And nothing works, need mysql reboot. Mysql configured use maximum 24 gb memory. I have hight weight InnoDB bases. (400000 rows, 30 gb). And on server multithread daemon, that makes many inserts in this tables, thats why InnoDB. There is my mysql config.

Before Here is the standard look for search results at Google…not bad but it really does not stand out that well either. Installing the User Script You may be asking yourself what makes this particular user script different from others. Take a look at the list of goodies that you get access to and you will understand: Multiple columns of results Removes “Sponsored Links” Add numbers to the results Auto-load more results Removes web search dialogues Open links in a new tab Favicons GooglePreview Self updating Can be configured from a simple user dialogue To get started click on the Webpage Install Button. Once you click on the Webpage Install Button you will see the following window asking for confirmation to add the user script to Firefox. Click Install to complete the process. GoogleMonkeyR in Action Refreshing the same search page shown above shows a noticeable difference already. The light blue background makes the search results stand out a bit better. This is an improvement from before but you will definitely want to have a look to see just how far you can go… Right click on the Greasemonkey Status Bar Icon, go to User Script Commands, and select GoogleMonkeyR Preferences. Once you have clicked on GoogleMonkeyR Preferences the search page will be shaded out and you will have access to the user script’s preferences. This is where you can really make your search results unique looking! Here are the changes that we started out with… After refreshing our search results things looked even better. A look at the entire page of results with our browser maximized and set for two columns.

  If I am more than a couple of metres from my access point (and I'm seeing this across various APs) with my newish Thinkpad Edge 15, running 10.10, the wifi performance becomes ... flaky. When this is happening, I see the following in dmesg, although I'm not sure if it's related: [ 2497.011099] intel ips 0000:00:1f.6: CPU power or thermal limit exceeded [ 2502.012711] intel ips 0000:00:1f.6: CPU power or thermal limit exceeded [ 2507.009254] intel ips 0000:00:1f.6: CPU power or thermal limit exceeded [ 2512.008367] intel ips 0000:00:1f.6: CPU power or thermal limit exceeded [ 2517.007467] intel ips 0000:00:1f.6: CPU power or thermal limit exceeded [ 2522.006558] intel ips 0000:00:1f.6: CPU power or thermal limit exceeded [ 2527.008157] intel ips 0000:00:1f.6: CPU power or thermal limit exceeded [ 2532.007251] intel ips 0000:00:1f.6: CPU power or thermal limit exceeded [ 2537.003838] intel ips 0000:00:1f.6: CPU power or thermal limit exceeded [ 2542.005427] intel ips 0000:00:1f.6: CPU power or thermal limit exceeded [ 2547.004496] intel ips 0000:00:1f.6: CPU power or thermal limit exceeded [ 2552.003611] intel ips 0000:00:1f.6: CPU power or thermal limit exceeded lspci -vvv has the following to say about my wireless adapter: 03:00.0 Network controller: Intel Corporation Centrino Wireless-N 1000 Subsystem: Intel Corporation Centrino Wireless-N 1000 BGN Control: I/O- Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR+ FastB2B- DisINTx- Status: Cap+ 66MHz- UDF- FastB2B- ParErr- DEVSEL=fast >TAbort- <TAbort- <MAbort- >SERR- <PERR- INTx- Latency: 0, Cache Line Size: 64 bytes Interrupt: pin A routed to IRQ 49 Region 0: Memory at f0500000 (64-bit, non-prefetchable) [size=8K] Capabilities: <access denied> Kernel driver in use: iwlagn Kernel modules: iwlagn If I get within a couple of metres of the access point, I still see that output in dmesg, but the connection stabilises. My question is threefold: how do I get better wifi range, what can/should I do about those messages in dmesg, and most crucially, are the two related? As ever let me know if there's other information that would help! Edit: I am using this machine in exactly the same locations I used my previous Thinkpad (T61) running various older versions of Ubuntu, so I definitely feel there is something wrong, rather me having unreasonable expectations of range!

This can be done with mdadm /dev/md? --grow -z newsize But somehow I can't figure out how to calculate the newsize argument. Is there a way to tell mdadm to grow to the biggest possible size? If not, how do I calculate the biggest possible size of the raid to use for the newsize argument?

• Juju Openstack bundle: Can't launch an instance

  - by user281985

  Deployed bundle:~makyo/openstack/2/openstack, on top of 7 physical boxes and 3 virtual ones. After changing vip_iface strings to point to right devices, e.g., br0 instead of eth0, and defining "/mnt/loopback|30G", in Cinder's block-device string, am able to navigate through openstack dashboard, error free. Following http://docs.openstack.org/grizzly/openstack-compute/install/apt/content/running-an-instance.html instructions, attempted to launch cirros 0.3.1 image; however, novalist shows the instance in error state. ubuntu@node7:~$ nova --debug boot --flavor 1 --image 28bed1bc-bc1c-4533-beee-8e0428ad40dd --key_name key2 --security_group default cirros REQ: curl -i http://keyStone.IP:5000/v2.0/tokens

• Drawing a circle in opengl es android, squiggly boundaries

  - by ladiesMan217

  I am new to OpenGL ES and facing a hard time drawing a circle on my GLSurfaceView. Here's what I have so far. the Circle Class public class MyGLBall { private int points=40; private float vertices[]={0.0f,0.0f,0.0f}; private FloatBuffer vertBuff; //centre of circle public MyGLBall(){ vertices=new float[(points+1)*3]; for(int i=3;i<(points+1)*3;i+=3){ double rad=(i*360/points*3)*(3.14/180); vertices[i]=(float)Math.cos(rad); vertices[i+1]=(float) Math.sin(rad); vertices[i+2]=0; } ByteBuffer bBuff=ByteBuffer.allocateDirect(vertices.length*4); bBuff.order(ByteOrder.nativeOrder()); vertBuff=bBuff.asFloatBuffer(); vertBuff.put(vertices); vertBuff.position(0); } public void draw(GL10 gl){ gl.glPushMatrix(); gl.glTranslatef(0, 0, 0); // gl.glScalef(size, size, 1.0f); gl.glColor4f(1.0f,1.0f,1.0f, 1.0f); gl.glVertexPointer(3, GL10.GL_FLOAT, 0, vertBuff); gl.glEnableClientState(GL10.GL_VERTEX_ARRAY); gl.glDrawArrays(GL10.GL_TRIANGLE_FAN, 0, points/2); gl.glDisableClientState(GL10.GL_VERTEX_ARRAY); gl.glPopMatrix(); } } I couldn't retrieve the screenshot of my image but here's what it looks like As you can see the border has crests and troughs thereby renering it squiggly which I do not want. All I want is a simple curve
