  • How do I access an Ubuntu VirtualBox guest at a static IP from an OS X host?

    - by David Siegel
    How does one configure an Ubuntu guest to use a static IP that's visible to an OS X host, and ensure that the static IP is independent of the host's network configuration? I previously used bridged networking for my guest, but I'm constantly moving my host between networks so the guest IP is always different. First, I tried setting the guest network configuration to NAT and forwarding host port 1022 to guest port 22, so I could at least ssh to a fixed address (localhost:1022): $ VBoxManage setextradata "Ubuntu Server" "VBoxInternal/Devices/e1000/0/LUN#0/Config/SSH/Protocol" "TCP" $ VBoxManage setextradata "Ubuntu Server" "VBoxInternal/Devices/e1000/0/LUN#0/Config/SSH/GuestPort" 22 $ VBoxManage setextradata "Ubuntu Server" "VBoxInternal/Devices/e1000/0/LUN#0/Config/SSH/HostPort" 1022 Then, $ ssh localhost -p 1022 ssh: connect to host localhost port 1022: Connection refused But this didn't work (guest has no network access with NAT and OS X refused the connection, as you can see). I'd love a general solution that would let me communicate with my guest at a fixed IP.

  • Smart subdomain routing via reverse proxy

    - by Trevor Hartman
    I have two servers on my home network: OSX Server and an Ubuntu Server. I'd love to have external subdomains osx.mydomain.com point to osx and ubuntu.mydomain.com point to ubuntu. I know the normal way to do this is to have a static external IP address for each, but that's not an option as this is just my home setup. My question is: is there a way to do this with some reverse proxy trickery? OSX is currently the default entry point for all traffic. I was able to setup a reverse proxy on OSX for ubuntu.mydomain.com on port 80, so web traffic was correctly being proxied to my ubuntu. I'd like to ssh and do a bunch of other stuff though!

  • error LNK2019 for ZLib sample code compiling.

    - by Nano HE
    Hello. I created win32 console application in vs2010 (without select the option of precompiled header). And I inserted the code below. but *.obj link failed. Could you provide me more information about the error. I searched MSDN, but still can't understand it. #include <stdio.h> #include "zlib.h" // Demonstration of zlib utility functions unsigned long file_size(char *filename) { FILE *pFile = fopen(filename, "rb"); fseek (pFile, 0, SEEK_END); unsigned long size = ftell(pFile); fclose (pFile); return size; } int decompress_one_file(char *infilename, char *outfilename) { gzFile infile = gzopen(infilename, "rb"); FILE *outfile = fopen(outfilename, "wb"); if (!infile || !outfile) return -1; char buffer[128]; int num_read = 0; while ((num_read = gzread(infile, buffer, sizeof(buffer))) > 0) { fwrite(buffer, 1, num_read, outfile); } gzclose(infile); fclose(outfile); } int compress_one_file(char *infilename, char *outfilename) { FILE *infile = fopen(infilename, "rb"); gzFile outfile = gzopen(outfilename, "wb"); if (!infile || !outfile) return -1; char inbuffer[128]; int num_read = 0; unsigned long total_read = 0, total_wrote = 0; while ((num_read = fread(inbuffer, 1, sizeof(inbuffer), infile)) > 0) { total_read += num_read; gzwrite(outfile, inbuffer, num_read); } fclose(infile); gzclose(outfile); printf("Read %ld bytes, Wrote %ld bytes, Compression factor %4.2f%%\n", total_read, file_size(outfilename), (1.0-file_size(outfilename)*1.0/total_read)*100.0); } int main(int argc, char **argv) { compress_one_file(argv[1],argv[2]); decompress_one_file(argv[2],argv[3]);} Output: 1>------ Build started: Project: zlibApp, Configuration: Debug Win32 ------ 1> zlibApp.cpp 1>d:\learning\cpp\cppvs2010\zlibapp\zlibapp\zlibapp.cpp(15): warning C4996: 'fopen': This function or variable may be unsafe.

  • Bridging LXC containers to host eth0 so they can have a public IP

    - by Vianney Stroebel
    UPDATE: I found the solution there: http://www.linuxfoundation.org/collaborate/workgroups/networking/bridge#No_traffic_gets_trough_.28except_ARP_and_STP.29 # cd /proc/sys/net/bridge # ls bridge-nf-call-arptables bridge-nf-call-iptables bridge-nf-call-ip6tables bridge-nf-filter-vlan-tagged # for f in bridge-nf-*; do echo 0 $f; done But I'd like to have expert opinions on this: is it safe to disable all bridge-nf-*? What are they here for? END OF UPDATE I need to bridge LXC containers to the physical interface (eth0) of my host, reading numerous tutorials, documents and blog posts on the subject. I need the containers to have their own public IP (which I've previously done KVM/libvirt). After two days of searching and trying, I still can't make it work with LXC containers. The host runs a freshly installed Ubuntu Server Quantal (12.10) with only libvirt (which I'm not using here) and lxc installed. I created the containers with : lxc-create -t ubuntu -n mycontainer So they also run Ubuntu 12.10. Content of /var/lib/lxc/mycontainer/config is: lxc.utsname = mycontainer lxc.mount = /var/lib/lxc/test/fstab lxc.rootfs = /var/lib/lxc/test/rootfs lxc.network.type = veth lxc.network.flags = up lxc.network.link = br0 lxc.network.name = eth0 lxc.network.veth.pair = vethmycontainer lxc.network.ipv4 = 179.43.46.233 lxc.network.hwaddr= 02:00:00:86:5b:11 lxc.devttydir = lxc lxc.tty = 4 lxc.pts = 1024 lxc.arch = amd64 lxc.cap.drop = sys_module mac_admin mac_override lxc.pivotdir = lxc_putold # uncomment the next line to run the container unconfined: #lxc.aa_profile = unconfined lxc.cgroup.devices.deny = a # Allow any mknod (but not using the node) lxc.cgroup.devices.allow = c *:* m lxc.cgroup.devices.allow = b *:* m # /dev/null and zero lxc.cgroup.devices.allow = c 1:3 rwm lxc.cgroup.devices.allow = c 1:5 rwm # consoles lxc.cgroup.devices.allow = c 5:1 rwm lxc.cgroup.devices.allow = c 5:0 rwm #lxc.cgroup.devices.allow = c 4:0 rwm #lxc.cgroup.devices.allow = c 4:1 rwm # /dev/{,u}random lxc.cgroup.devices.allow = c 1:9 rwm lxc.cgroup.devices.allow = c 1:8 rwm lxc.cgroup.devices.allow = c 136:* rwm lxc.cgroup.devices.allow = c 5:2 rwm # rtc lxc.cgroup.devices.allow = c 254:0 rwm #fuse lxc.cgroup.devices.allow = c 10:229 rwm #tun lxc.cgroup.devices.allow = c 10:200 rwm #full lxc.cgroup.devices.allow = c 1:7 rwm #hpet lxc.cgroup.devices.allow = c 10:228 rwm #kvm lxc.cgroup.devices.allow = c 10:232 rwm Then I changed my host /etc/network/interfaces to: auto lo iface lo inet loopback auto br0 iface br0 inet static bridge_ports eth0 bridge_fd 0 address 92.281.86.226 netmask 255.255.255.0 network 92.281.86.0 broadcast 92.281.86.255 gateway 92.281.86.254 dns-nameservers 213.186.33.99 dns-search ovh.net When I try command line configuration ("brctl addif", "ifconfig eth0", etc.) my remote host becomes inaccessible and I have to hard reboot it.

  • Option do not show schema names in SQL Server Management Studio

    - by Jörgen Sigvardsson
    I love the fact that tree and list controls in Windows allows incremental searches. Just select a starting point, and type, and the control will select the best matching node for you. This works in SSMS, but there's an annoying problem, especially so in the table node. SSMS prefixes all table names with the schema name and a dot. To make an incremental search here, I have to type 'dbo.', followed by whatever I'm searching for. Is there an option to turn off this table name representation in SSMS? I hope I'm asking this on the right stack exchange site. If you feel it's off base, let me know!

  • [C#] Not enough memory or not enough handles?

    - by Nayan
    I am working on a large scale project where a custom (pretty good and robust) framework has been provided and we have to use that for showing up forms and views. There is abstract class StrategyEditor (derived from some class in framework) which is instantiated whenever a new StrategyForm is opened. StrategyForm (a customized window frame) contains StrategyEditor. StrategyEditor contains StrategyTab. StrategyTab contains StrategyCanvas. This is a small portion of the big classes to clarify that there are many objects that will be created if one StrategyForm object is allocated in memory at run-time. My component owns all these classes mentioned above except StrategyForm whose code is not in my control. Now, at run-time, user opens up many strategy objects (which trigger creation of new StrategyForm object.) After creating approx. 44 strategy objects, we see that the USER OBJECT HANDLES (I'll use UOH from here onwards) created by the application reaches to about 20k+, while in registry the default amount for handles is 10k. Read more about User Objects here. Testing on different machines made it clear that the number of strategy objects opened is different for message to pop-up - on one m/c if it is 44, then it can be 40 on another. When we see the message pop-up, it means that the application is going to respond slowly. It gets worse with few more objects and then creation of window frames and subsequent objects fail. We first thought that it was not-enough-memory issue. But then reading more about new in C# helped in understanding that an exception would be thrown if app ran out of memory. This is not a memory issue then, I feel (task manager also showed 1.5GB+ available memory.) M/C specs Core 2 Duo 2GHz+ 4GB RAM 80GB+ free disk space for page file Virtual Memory set: 4000 - 6000 My questions Q1. Does this look like a memory issue and I am wrong that it is not? Q2. Does this point to exhaustion of free UOHs (as I'm thinking) and which is resulting in failure of creation of window handles? Q3. How can we avoid loading up of an StrategyEditor object (beyond a threshold, keeping an eye on the current usage of UOHs)? (we already know how to fetch number of UOHs in use, so don't go there.) Keep in mind that the call to new StrategyForm() is outside the control of my component. Q4. I am bit confused - what are Handles to user objects exactly? Is MSDN talking about any object that we create or only some specific objects like window handles, cursor handles, icon handles? Q5. What exactly cause to use up a UOH? (almost same as Q4) I would be really thankful to anyone who can give me some knowledgeable answers. Thanks much! :)

  • How do I enable a disabled Event Notification.

    - by Derick Mayberry
    I have a scenerio where I am using external notification to process documents being sent in from the entire navy fleet, normally I have no problems, but just a few days ago an administrator changed passwords and I my queue processing failed and I rolled back the transaction with this C# code: catch (Exception) { TransporterService.WriteEventToWindowsLog(AppName, "Rolling Back Transaction:", ERROR); broker.Tran.Rollback(); break; } after which my target queue would continue to fill up but nothing to the external activation queue. Does the Event Notification get disabled once a transaction is rolled back? Should I have done a broker.EndDialog here when catching my exception? Also, after my event notification is disabled(if that is actually whats happening) how do I re engage it? Do I have to drop it and recreate it? Thank in advance for any help, I love Service Broker and its workign wonderfully except for this bug that I hope to fix soon.

It was the highest option for intel for this laptop. So i am assuming it is somewhat fast. But i'd like to learn what these specs mean. Any help would be greatly appreciated. i am not really a computer guy but would love to learn about what I am buying. Thanks!

    I have a large ZFS pool of 4 combined drives. Now, the filesystem can not be mounted: pool: tank state: UNAVAIL status: One or more devices could not be opened.

  • Suggest Wireless AP

    - by sunny
    I'm doing a data and voice install for a client in the hotel industry. I'm done with voice and am looking for my options to provide a Wireless AP. The building's dimensions are 100ft X 50ft. There are a ton of options out there which have left me confused now. Please help me decide. I am not clear as to how I should ensure that the Wireless Network is visible throughout the premises. Personally I would love to setup a WDS on 3-4 linksys wrt54gl routers using OpenWRT. Is this advisable? If not please recommend some other AP's. If a more expensive appliance is absolutely necessary, then please suggest something that can be powered using IEEE 802.3af PoE. Thanks

  • LGA 1155 or LGA 2011? Which has a brighter future?

    - by Langdon
    I'd basically like to rehash this question, only 22 months later. The last system I built was in 2006, shortly after AMD came out with socket AM2. I was able to upgrade the processor on it 3 times and would love to do the same with my next computer. Since AMD seems to be lagging, I'm going for Intel this time. I've read that Intel changes chip sets all the time, so there's no safe bet. I also read (1 comment on 1 forum) that said LGA 2011 will have 8-core support, but LGA 1155 won't, which leads me to believe that LGA 2011 might be a better choice. Anyone have any good advice for me?

  • Get the touch position inside the imageview in android

    - by Manikandan
    I have a imageview in my activity and I am able to get the position where the user touch the imageview, through onTouchListener. I placed another image where the user touch over that image. I need to store the touch position(x,y), and use it in another activity, to show the tags. I stored the touch position in the first activity. In the first activity, my imageview at the top of the screen. In the second activity its at the bottom of the screen. If I use the position stored from the first acitvity, it place the tag image at the top, not on the imageview, where I previously clicked in the first activity. Is there anyway to get the position inside the imageview. FirstActivity: cp.setOnTouchListener(new OnTouchListener() { @Override public boolean onTouch(View v, MotionEvent event) { // TODO Auto-generated method stub Log.v("touched x val of cap img >>", event.getX() + ""); Log.v("touched y val of cap img >>", event.getY() + ""); x = (int) event.getX(); y = (int) event.getY(); tag.setVisibility(View.VISIBLE); int[] viewCoords = new int[2]; cp.getLocationOnScreen(viewCoords); int imageX = x - viewCoords[0]; // viewCoods[0] is the X coordinate int imageY = y - viewCoords[1]; // viewCoods[1] is the y coordinate Log.v("Real x >>>",imageX+""); Log.v("Real y >>>",imageY+""); RelativeLayout rl = (RelativeLayout) findViewById(R.id.lay_lin); ImageView iv = new ImageView(Capture_Image.this); Bitmap bm = BitmapFactory.decodeResource(getResources(), R.drawable.tag_icon_32); iv.setImageBitmap(bm); RelativeLayout.LayoutParams params = new RelativeLayout.LayoutParams( RelativeLayout.LayoutParams.WRAP_CONTENT, RelativeLayout.LayoutParams.WRAP_CONTENT); params.leftMargin = x; params.topMargin = y; rl.addView(iv, params); Intent intent= new Intent(Capture_Image.this,Tag_Image.class); Bundle b=new Bundle(); b.putInt("xval", imageX); b.putInt("yval", imageY); intent.putExtras(b); startActivity(intent); return false; } }); In TagImage.java I used the following: im = (ImageView) findViewById(R.id.img_cam22); b=getIntent().getExtras(); xx=b.getInt("xval"); yy=b.getInt("yval"); im.setOnTouchListener(new OnTouchListener() { @Override public boolean onTouch(View v, MotionEvent event) { int[] viewCoords = new int[2]; im.getLocationOnScreen(viewCoords); int imageX = xx + viewCoords[0]; // viewCoods[0] is the X coordinate int imageY = yy+ viewCoords[1]; // viewCoods[1] is the y coordinate Log.v("Real x >>>",imageX+""); Log.v("Real y >>>",imageY+""); RelativeLayout rl = (RelativeLayout) findViewById(R.id.lay_lin); ImageView iv = new ImageView(Tag_Image.this); Bitmap bm = BitmapFactory.decodeResource(getResources(), R.drawable.tag_icon_32); iv.setImageBitmap(bm); RelativeLayout.LayoutParams params = new RelativeLayout.LayoutParams( 30, 40); params.leftMargin =imageX ; params.topMargin = imageY; rl.addView(iv, params); return true; } });

This question is related: Switch between databases, use two databases simultaneously question. cs="Data Source=mywebsite.com;Initial Catalog=database;User Id=root;Password=toor;Connect Timeout=10;Pooling='true';" using (SqlConnection cnn = new SqlConnection(WebConfigurationManager.ConnectionStrings["cs"].ConnectionString)) { using (SqlCommand cmmnd = new SqlCommand("", cnn)) { try { cnn.Open(); #region Header & Description cmmnd.Parameters.Add("@CatID", SqlDbType.Int).Value = catId; cmmnd.CommandText = "SELECT UpperID, Title, Description FROM Categories WHERE CatID=@CatID;"; string mainCat = String.Empty, rootCat = String.Empty; using (SqlDataReader rdr = cmmnd.ExecuteReader()) { if (rdr.Read()) { mainCat = rdr["Title"].ToString(); upperId = Convert.ToInt32(rdr["UpperID"]); description = rdr["Title"]; } else { Response.Redirect("/", false); } } if (upperId > 0) //If upper category exists add its name { cmmnd.Parameters["@CatID"].Value = upperId; cmmnd.CommandText = "SELECT Title FROM Categories WHERE CatID=@CatID;"; using (SqlDataReader rdr = cmmnd.ExecuteReader()) { if (rdr.Read()) { rootCat = "<a href='x.aspx'>" + rdr["Title"] + "</a> &raquo; "; } } } #endregion #region Sub-Categories if (upperId == 0) //show only at root categories { cmmnd.Parameters["@CatID"].Value = catId; cmmnd.CommandText = "SELECT Count(CatID) FROM Categories WHERE UpperID=@CatID;"; if (Convert.ToInt32(cmmnd.ExecuteScalar()) > 0) { cmmnd.CommandText = "SELECT CatID, Title FROM Categories WHERE UpperID=@CatID ORDER BY Title;"; using (SqlDataReader rdr = cmmnd.ExecuteReader()) { while (rdr.Read()) { subcat.InnerHtml += "<a href='x.aspx'>" + rdr["Title"].ToString().ToLower() + "</a>\n"; description += rdr["Title"] + ", "; } } } } #endregion } catch (Exception ex) { HasanG.LogException(ex, Request.RawUrl, HttpContext.Current); Response.Redirect("/", false); } finally { cnn.Close(); } } } The random errors I'm receiving are: A transport-level error has occurred when sending the request to the server.

  • Boost::Spirit::Qi autorules -- avoiding repeated copying of AST data structures

    - by phooji
    I've been using Qi and Karma to do some processing on several small languages. Most of the grammars are pretty small (20-40 rules). I've been able to use autorules almost exclusively, so my parse trees consist entirely of variants, structs, and std::vectors. This setup works great for the common case: 1) parse something (Qi), 2) make minor manipulations to the parse tree (visitor), and 3) output something (Karma). However, I'm concerned about what will happen if I want to make complex structural changes to a syntax tree, like moving big subtrees around. Consider the following toy example: A grammar for s-expr-style logical expressions that uses autorules... // Inside grammar class; rule names match struct names... pexpr %= pand | por | var | bconst; pand %= lit("(and ") >> (pexpr % lit(" ")) >> ")"; por %= lit("(or ") >> (pexpr % lit(" ")) >> ")"; pnot %= lit("(not ") >> pexpr >> ")"; ... which leads to parse tree representation that looks like this... struct var { std::string name; }; struct bconst { bool val; }; struct pand; struct por; struct pnot; typedef boost::variant<bconst, var, boost::recursive_wrapper<pand>, boost::recursive_wrapper<por>, boost::recursive_wrapper<pnot> > pexpr; struct pand { std::vector<pexpr> operands; }; struct por { std::vector<pexpr> operands; }; struct pnot { pexpr victim; }; // Many Fusion Macros here Suppose I have a parse tree that looks something like this: pand / ... \ por por / \ / \ var var var var (The ellipsis means 'many more children of similar shape for pand.') Now, suppose that I want negate each of the por nodes, so that the end result is: pand / ... \ pnot pnot | | por por / \ / \ var var var var The direct approach would be, for each por subtree: - create pnot node (copies por in construction); - re-assign the appropriate vector slot in the pand node (copies pnot node and its por subtree). Alternatively, I could construct a separate vector, and then replace (swap) the pand vector wholesale, eliminating a second round of copying. All of this seems cumbersome compared to a pointer-based tree representation, which would allow for the pnot nodes to be inserted without any copying of existing nodes. My question: Is there a way to avoid copy-heavy tree manipulations with autorule-compliant data structures? Should I bite the bullet and just use non-autorules to build a pointer-based AST (e.g., http://boost-spirit.com/home/2010/03/11/s-expressions-and-variants/)?

  • Install latest kernel to Ubuntu and have grub acknowledge the new installed kernel

    - by Phuong Nguyen
    I have an installed Ubuntu Distro (Karmic 9.10) already. However, due to some problems with xorg ati driver, I cannot standby my computer. Some guy have suggested me to try the latest version of xorg driver which in turn requires a newer version of Linux kernel than the newest release available from Ubuntu Central Repository (2.6.33). I have searched though several articles on how to install a custom Linux kernel. However, these articles are so 2004/2005 and they were talking about lilo (???). Since then, I'm afraid that I cannot make the Grub Boot recognize the new Linux kernel properly (I'm just a newbie to Linux). I would love to know how to install the kernel into Ubuntu and have grub acknowledge the new installed kernel.

  • Way to auto resize photos before uploaded to cloud service?

    - by AndroidHustle
    I love using auto syncing services to have my photos taken with my smartphone stored on a cloud storage service. One problem though is that the photos are uploaded in high resolution and takes up a lot of space on the drive. I wonder if any one knows of a service/strategy to have the auto uploaded photo resized to have it occupy less space when auto stored? That is, without me having to take the photos with lesser quality, I still want photos taken with the highest quality since I may take a photo I really like.

  • PacketFence Installation?

    - by Charles Miton
    So I've stumbled across PacketFence during my search for a decent Network Access Control system. After doing a little research about it's capabilities I've come to realize it's meets all the requirements that I was looking for. Unfortunately, being primarily a MS Administrator, I'm having many issues trying to successfully getting it up and running. Is there anyone or any place that has a step-by-step tutorial on how to do this? I love the prospect of using Open Source software, but need some help jumping this particular hurdle. I'm trying to use CentOS for the OS but I'm open to alternatives if thats what it takes to get this system up and running.

  • Display current layout WITHOUT using Windows's language bar

    - by Shiki
    Basically I love quick launch and pinning is not for me, I can't just pin 50 apps, nor pin them to start menu / use the win + type method. Anyway, Quick Launch works perfectly under Win7 IF you don't use the language bar. If you use it, sometimes (or always) it may fail to start/appear, you have to readd it. So my question is: Is there a tray app, a RainMeter way to show this? (First would be better). Thanks. (Best would be if I could switch layout globally but that train is gone. (Look at the changing global layout. Thank you Microsoft. (Irony included)).

  • slow DNS resolution

    - by Ehsan
    I have a DNS server that resolves all queries for an internal group of servers. It is a bind on CentOS 5.5 (same as RHEL5) and I have set it up to allow recursion and resolve direction without any forwarders. The problem I am facing is that it takes a freakishly long amount of time to resolve a name for the first time. (in the magnitudes of 20 sec) This causes clients to give timeout. When I set it to forward all to Google's public DNS, i.e. 8.8.8.8+8.8.4.4, it works very nicely (within a second). I tried monitoring the traffic on the net to see why it is doing this: [root@ns1 ~]# tcpdump -nnvvvA -s0 udp tcpdump: listening on eth0, link-type EN10MB (Ethernet), capture size 65535 bytes 23:06:36.137797 IP (tos 0x0, ttl 64, id 35903, offset 0, flags [none], proto: UDP (17), length: 60) 172.17.1.10.36942 > 172.17.1.4.53: [udp sum ok] 19773+ A? www.paypal.com.

  • Power User - archive Outlook mail items into SQL Server

    - by marc_s
    I am looking (and so far not finding any) for a solution to archive e-mail items from my Outlook into SQL Server. My PST is beginning to get really really big, and I'd love to extract my older e-mail into SQL Server in a way so I can still easily find mails if needed. I would prefer SQL Server as the storage medium since I'm familiar with it, and it's rock solid - I don't want to have a collection of PST files or CHM files or anything like that. Does anyone know of such a solution? I'm a power/home user - I can't afford $5'000 enterprise licenses - I need a sub-$100 solution for private use.

  • I have nice headphones. Need a wireless USB microphone so I don't have to switch to a headset to make a call

    - by mattalexx
    Right now, I have a pair of Sennheiser HD595 headphones. They are plugged into a DAC/headphone amp. I spend all day listening to music through them and they sound awesome. Then, for making calls, I have a wireless USB headset from Logitech. Problem is, I can't make calls when I'm wearing my Sennheisers but I wouldn't want to listen to music all day using the Logitech headset. So I spend my day switching in between. So the question is, how can I make calls while wearing the headphones of my choice? One thing I thought of is a wireless USB microphone that I can clip to the Sennheisers. So I'd wear the Sennheisers with this mic all day and ditch the Logitech headset. But it doesn't look like anyone makes a microphone like this. By the way, I would love if the solution didn't transmit the sound of my clacky keyboard or noisy wood flooring.

  • Should I split my website into different servers

    - by Nyxynyx
    I have a website where a user uploads photos, the photos gets resized and thumbnailed, and stored on the server. At the same time, there are some INSERTS into a MySQL table regarding the photo uploaded (like description, user id etc). The site currently runs off a managed VPS, and I love the support it provides. However it is expensive to store the many small photos and the resizing and thumbnailing processes do cause spikes on the app performance. (Amazon S3 is pretty expensive, especially considering the costs for uploading many small files) Question: Will it be a good idea to move the image processing operations and image storage to another server which is an unmanaged dedicated server with a much lower cost/gb and keep the current VPS for its 24/7 support and hosting the webapp? Or should I move the entire site to the dedicated server?

  • Java List to Excel Columns

  • Is there a global inbox for android?

    - by Loony2nz
    I'm a Blackberry fan and I have been aching to get a phone with a better UI (and not the jesusPhone). I was looking at the Android platform and find it quite fun to play with. However, one of the crucial elements of my BB that I love to death is the global inbox of all my email accounts. (not to mention the BB messenger, but I can live without that). Is there an addon or does the android have this feature natively? I played with my friend's Verizon Droid, and she couldn't tell me. Thanks!
