• "cannot open file system. File system seems damaged "

  - by suresh kadiri

  I was using windows 7 till yesterday. I tried to install ubuntu 14. 04 Lts version yesterday with in windows 7. But it was not succeeded. Then I decided to install ubuntu only. By mistake I installed ubuntu in whole disk. After that to get deleted partitions I installed testdisk. I also used deeper search option. Now I'm getting "file system damaged". It shows The hard disk (320GB /298 GiB) seems to small! (<473 GB /441 GB) Check the Harddisk size: HD Jumpers setings, BIOS detection... The following partitions can't be recovered: Partition start end size in sectrors Linux 19077 177 45 57604 81 13 618930716 Linux 19080 192 57 57607 96 25 618930716 With ubcd also I used testdisk option. Same result comes."cannot open file system. File system seems damaged ". I have all my stuff in hard disk. Please help me to get recover my files in deleted partitions.

• Building NanoBSD inside a jail

  - by ptomli

  I'm trying to setup a jail to enable building a NanoBSD image. It's actually a jail on top of a NanoBSD install. The problem I have is that I'm unable to mount the md device in order to do the 'build image' part. Is it simply not possible to mount an md device inside a jail, or is there some other knob I need to twiddle? On the host /etc/rc.conf.local jail_enable="YES" jail_mount_enable="YES" jail_list="build" jail_set_hostname_allow="NO" jail_build_hostname="build.vm" jail_build_ip="192.168.0.100" jail_build_rootdir="/mnt/zpool0/jails/build/home" jail_build_devfs_enable="YES" jail_build_devfs_ruleset="devfsrules_jail_build" /etc/devfs.rules [devfsrules_jail_build=5] # nothing Inside the jail [root@build /usr/obj/nanobsd.PROLIANT_MICROSERVER]# sysctl security.jail security.jail.param.cpuset.id: 0 security.jail.param.host.hostid: 0 security.jail.param.host.hostuuid: 64 security.jail.param.host.domainname: 256 security.jail.param.host.hostname: 256 security.jail.param.children.max: 0 security.jail.param.children.cur: 0 security.jail.param.enforce_statfs: 0 security.jail.param.securelevel: 0 security.jail.param.path: 1024 security.jail.param.name: 256 security.jail.param.parent: 0 security.jail.param.jid: 0 security.jail.enforce_statfs: 1 security.jail.mount_allowed: 1 security.jail.chflags_allowed: 1 security.jail.allow_raw_sockets: 0 security.jail.sysvipc_allowed: 0 security.jail.socket_unixiproute_only: 1 security.jail.set_hostname_allowed: 0 security.jail.jail_max_af_ips: 255 security.jail.jailed: 1 [root@build /usr/obj/nanobsd.PROLIANT_MICROSERVER]# mdconfig -l md2 md0 md1 md0 and md1 are the ramdisks of the host. bsdlabel looks sensible [root@build /usr/obj/nanobsd.PROLIANT_MICROSERVER]# bsdlabel /dev/md2s1 # /dev/md2s1: 8 partitions: # size offset fstype [fsize bsize bps/cpg] a: 1012016 16 4.2BSD 0 0 0 c: 1012032 0 unused 0 0 # "raw" part, don't edit newfs runs ok [root@build /usr/obj/nanobsd.PROLIANT_MICROSERVER]# newfs -U /dev/md2s1a /dev/md2s1a: 494.1MB (1012016 sectors) block size 16384, fragment size 2048 using 4 cylinder groups of 123.55MB, 7907 blks, 15872 inodes. with soft updates super-block backups (for fsck -b #) at: 160, 253184, 506208, 759232 mount fails [root@build /usr/obj/nanobsd.PROLIANT_MICROSERVER]# mount /dev/md2s1a _.mnt/ mount: /dev/md2s1a : Operation not permitted UPDATE: One of my colleagues pointed out There are some file systems types that can't be securely mounted within a jail no matter what, like UFS, MSDOFS, EXTFS, XFS, REISERFS, NTFS, etc. because the user mounting it has access to raw storage and can corrupt it in a way that it will panic entire system. From http://www.mail-archive.com/[email protected]/msg160389.html So it seems that the standard nanobsd.sh won't run inside a jail while it uses the md device to build the image. One potential solution I'll try is to chroot from the host into the build jail, rather than jexec a shell.

• A Quantity class with units

  - by Ryan Ohs

  Goals Create a class that associates a numeric quantity with a unit of measurement. Provide support for simple arithmetic and comparison operations. Implementation An immutable class (Could have been struct but I may try inheritance later) Unit is stored in an enumeration Supported operations: Addition w/ like units Subtraction w/ like units Multiplication by scalar Division by scalar Modulus by scalar Equals() >, >=, <, <=, == IComparable ToString() Implicit cast to Decimal The Source The souce can be downloaded from Github. Notes This class does not support any arithmetic that would modify the unit. This class is not suitable for manipulating currencies. Future Ideas Have a CompositeQuantity class that would allow quantities with unlike units to be combined. Similar currency class with support for allocations/distributions. Provide conversion between units. (Actually I think this would be best placed in an external service. Many situations I deal with require some sort of dynamic conversion ratio.)

• Is it ok to replace optimized code with readable code?

  - by Coder

  Sometimes you run into a situation where you have to extend/improve an existing code. You see that the old code is very lean, but it's also difficult to extend, and takes time to read. Is it a good idea to replace it with modern code? Some time ago I liked the lean approach, but now, it seems to me that it's better to sacrifice a lot of optimizations in favor of higher abstractions, better interfaces and more readable, extendable code. The compilers seem to be getting better as well, so things like struct abc = {} are silently turned into memsets, shared_ptrs are pretty much producing the same code as raw pointer twiddling, templates are working super good because they produce super lean code, and so on. But still, sometimes you see stack based arrays and old C functions with some obscure logic, and usually they are not on the critical path. Is it good idea to change such code if you have to touch a small piece of it either way?

• How to know which partition is which?

  Well I was just wondering what partition belongs to which. On my computer I have Windows 7 and two Ubuntu systems (it was an accident, which is why I need to know which partition is which).

• Why is IIS7 not compressing my static files?

  - by Peter Evjan

  I am trying to get IIS to compress jquery.js (and all other static files, but using jquery as the example here) on my localhost, but something goes wrong. The funny part is that when I look in my %SystemDrive%\inetpub\temp\IIS Temporary Compressed Files\MySiteName, I see the jquery.js file there, and its size is 24 KB. But in the browser, according to the Net tab on Firebug, the size is 69 kb. I've tried the following: - Checked that my browser accept compression. I found "Accept-Encoding gzip, deflate" in the request header via Firebug - Enabling Failed Request Tracing. Nothing turns up in the %SystemDrive%\inetpub\logs\FailedReqLogFiles folder after I do my request though.

  I have an: Ubuntu 12.04 with proprietary Boardcom STA Wireless driver installed BCM43224 802.11a/b/g/n wireless card TP-LINK TD-W8101G 54Mbps Wireless ADSL2+ Modem Router Yesterday before I went to sleep, I still connect to my wireless access point, this morning when I start my laptop I don't see it in the list - there are some neighbors listed but not mine.

• Distribute Sort Sample Service

  - by kaleidoscope

  How it works? Using the front-end of the service, a user can specify a size in MB for the input data set to sort. Algorithm CreateAndSplit The CreateAndSplit task generates the input data and stores them as 10 blobs in the utility storage. The URLs to these blobs are packaged as Separate work items and written to the queue. · Separate The Separate task reads the blobs with the random numbers created in the CreateAndSplit task and places the random numbers into buckets. The interval of the numbers that go into one bucket is chosen so that the expected amount of numbers (assuming a uniform distribution of the numbers in the original data set) is around 100 kB. Each bucket is represented as a blob container in utility storage. Whenever there are 10 blobs in one bucket (i.e., the placement in this bucket is complete because we had 10 original splits), the separate task will generate a new Sort task and write the task into the queue. · Sort The Sort task merges all blobs in a single bucket and sorts them using a standard sort algorithm. The result is stored as a blob in utility storage. · Concat The concat task merges the results of all Sort tasks into a single blob. This blob can be downloaded as a text file using this Web page. As the resulting file is presented in text format, the size of the file is likely to be larger than the specified input file. Anish

• Bot strategy in an arena

  - by joulesm

  I am writing the player's behavior for an arena game, and I'm wondering if you could offer some strategies. I'm writing it in Python, but I'm just interested in the high level game play. Here are the game aspects: Arena is a circle of a given size. The arena's size shrinks every round to help break any ties. Players are much smaller circles, and can be on teams of 1 or 2 players. Players attack by colliding with other players, and based on the physics of the collision (speed of both players, angle), one could force another player out of the arena. Once a player is out of the arena, they are out of the game (for that round). The goal is to be on the only team with players left in the arena. All other players have been pushed (through collisions or mistakes) out of the arena. It is possible for there to be no winner if the last two players exit the arena at the same time. Once the player has been programmed, the game just runs. There is no human intervention in the game. I'm thinking it's easiest to implement a few simple programmatic rules for my player to follow. For example, stay close to center of the arena, attack opponents from the inner side of the arena, etc. Are there any good simple game strategies? Would adding a random aspect to the game help? For example, to avoid predictability by the other team or something. Thanks in advance.

• Only 1080p youtube videos work properly

  - by oshirowanen

  I have Ubuntu 12.04 64bit installed/full updated and have noticed that I can only play 1080p youtube videos properly on full screen. All other resolutions, 480, 720, 1440 etc do not go into full screen properly. Please have a look at the attached images. You will notice that only the 1080p video has the video control bar right at the bottom with a respectable text size. All other videos don't have the video control bar right at the bottom on the screen, and the control bar text is too small. I've had this problem for ages, but finally decided to ask about it. 480p: Notice the bottom control bar, it's not at the bottom on the screen and the video has borders on the sides: 720p: Notice the bottom control bar, it's not at the bottom on the screen and the video has borders on the sides and the text is tiny: 1080p: This is the only one that works as expected, i.e. controls right at the bottom, and good font size and no borders on the sides: 1440p: Notice the bottom control bar, it's not at the bottom on the screen and the video has borders on the sides: How do I correct this problem so I can play all different video resolutions at full screen. The flash version I have installed in Chromium is Adobe Flash Player - Version: 11.2 r202 - Shockwave Flash 11.2 r202

• Are there any statistics on the number of networks using Ethernet Jumbo frames?

  - by Russell Heilling

  I am often told by Sales Engineers and Product managers that a Layer 2 Ethernet service is not fit for purpose if the maximum supported frame size is in the 1518-1522 range (enough to support standard Ethernet frames or VLAN tagged frames). Or in other words: an MTU of 1500 is not enough (see this blog post for my definition of MTU and a short rant on how the term is often misused) I am never able to get any details from them on: a) What proportion of customers (Enterprise / SMB) require Jumbo frames b) What are typical expectations on frame size for Jumbos on WAN links? 1600, 2000, 9k, etc... I know that in Telco and Data Centre environments Jumbos are pretty common, but I am after some insight as to how common this is within Enterprise and SMB networks.

• unseen/unknown function definition in linux source

  - by Broncha

  Can any one please explain this piece of code I found in the linux kernel source. I see a lots of code like this in linux and minix kernel but dont seem to find what it does (even if C compilers support that kind of function definition) /* IRQs are disabled and uidhash_lock is held upon function entry. * IRQ state (as stored in flags) is restored and uidhash_lock released * upon function exit. */ static void free_user(struct user_struct *up, unsigned long flags) __releases(&uidhash_lock) { uid_hash_remove(up); spin_unlock_irqrestore(&uidhash_lock, flags); key_put(up->uid_keyring); key_put(up->session_keyring); kmem_cache_free(uid_cachep, up); } I cannot find out if this reference __releases(&uidhash_lock) before the parenthesis starts is allowed OR supported. (It sure is supported as it is in the linux kernel)

• Aligning text to the bottom of a div: am I confused about CSS or about blueprint? [closed]

  - by larsks

  I've used Blueprint to prototype a very simple page layout...but after reading up on absolute vs. relative positioning and a number of online tutorials regarding vertical positioning, I'm not able to get things working the way I think they should. Here's my html: <div class="container" id="header> <div class="span-4" id="logo"> <img src="logo.png" width="150" height="194" /> </div> <div class="span-20 last" id="title"> <h1 class="big">TITLE</h1> </div> </div> The document does include the blueprint screen.css file. I want TITLE aligned with the bottom of the logo, which in practical terms means the bottom of #header. This was my first try: #header { position: relative; } #title { font-size: 36pt; position: absolute; bottom: 0; } Not unexpectedly, in retrospect, this puts TITLE flush left with the left edge of #header...but it failed to affect the vertical positioning of the title. So I got exactly the opposite of what I was looking for. So I tried this: #title { position: relative; } #title h1 { font-size: 36pt; position: absolute; bottom: 0; } My theory was that this would allign the h1 element with the bottom of the containing div element...but instead it made TITLE disappear, completely. I guess this means that it's rendering off the visible screen somewhere. At this point I'm baffled. I'm hoping someone here can point me in the right direction. Thanks!

• Why won't vyatta allow SMTP through my firewall?

  - by Solignis

  I am setting up a vyatta router on VMware ESXi, But I see to have hit a major snag, I could not get my firewall and NAT to work correctly. I am not sure what was wrong with NAT but it "seems" to be working now. But the firewall is not allowing traffic from my WAN interface (eth0) to my LAN (eth1). I can confirm its the firewall because I disabled all firewall rules and everything worked with just NAT. If put the firewalls (WAN and LAN) back in place nothing can get through to port 25. I am not really sure what the issue could be I am using pretty basic firewall rules, I wrote the rules while looking at the vyatta docs so unless there is something odd with the documentation they "should" be working. Here is my NAT rules so far; vyatta@gateway# show service nat rule 20 { description "Zimbra SNAT #1" outbound-interface eth0 outside-address { address 74.XXX.XXX.XXX } source { address 10.0.0.17 } type source } rule 21 { description "Zimbra SMTP #1" destination { address 74.XXX.XXX.XXX port 25 } inbound-interface eth0 inside-address { address 10.0.0.17 } protocol tcp type destination } rule 100 { description "Default LAN -> WAN" outbound-interface eth0 outside-address { address 74.XXX.XXX.XXX } source { address 10.0.0.0/24 } type source } Then here is my firewall rules, this is where I believe the problem is. vyatta@gateway# show firewall all-ping enable broadcast-ping disable conntrack-expect-table-size 4096 conntrack-hash-size 4096 conntrack-table-size 32768 conntrack-tcp-loose enable ipv6-receive-redirects disable ipv6-src-route disable ip-src-route disable log-martians enable name LAN_in { rule 100 { action accept description "Default LAN -> any" protocol all source { address 10.0.0.0/24 } } } name LAN_out { } name LOCAL { rule 100 { action accept state { established enable } } } name WAN_in { rule 20 { action accept description "Allow SMTP connections to MX01" destination { address 74.XXX.XXX.XXX port 25 } protocol tcp } rule 100 { action accept description "Allow established connections back through" state { established enable } } } name WAN_out { } receive-redirects disable send-redirects enable source-validation disable syn-cookies enable SIDENOTE To test for open ports I have using this website, http://www.yougetsignal.com/tools/open-ports/, it showed port 25 as open without the firewall rules and closed with the firewall rules. UPDATE Just to see if the firewall was working properly I made a rule to block SSH from the WAN interface. When I checked for port 22 on my primary WAN address it said it was still open even though I outright blocked the port. Here is the rule I used; rule 21 { action reject destination { address 74.219.80.163 port 22 } protocol tcp } So now I am convinced either I am doing something wrong or the firewall is not working like it should.

• Throughput = BS * IOPS?

  - by Marvin

  I've seen in many places that throughput = bs * iops should be true. For example writing at 128k block size to a SAS disk that can support 190 IOPS should give a throughput of ~23 MBps - 23.75(MBs) = 128(BS)*190(SAS-15 IOPS)/1024. Now when I tested it in a VM against a monster NetApp filer I got theses results: # dd if=/dev/zero of=/tmp/dd.out bs=4k count=2097152 8589934592 bytes (8.6 GB) copied, 61.5996 seconds, 139 MB/s To view the IO rate of the VM I used iostat and esxtop, and they both showed around 250 IOPS. So to my understanding the throughput was supposed to be ~1000k: 1000(KBs) = 4(BS)*250(IOPS). dd of 8GB is twice the size of RAM of course, so no page caching here. What am I missing? Thanks!

• Data Aggregation of CSV files java

  - by royB

  I have k csv files (5 csv files for example), each file has m fields which produce a key and n values. I need to produce a single csv file with aggregated data. I'm looking for the most efficient solution for this problem, speed mainly. I don't think by the way that we will have memory issues. Also I would like to know if hashing is really a good solution because we will have to use 64 bit hashing solution to reduce the chance for a collision to less than 1% (we are having around 30000000 rows per aggregation). For example file 1: f1,f2,f3,v1,v2,v3,v4 a1,b1,c1,50,60,70,80 a3,b2,c4,60,60,80,90 file 2: f1,f2,f3,v1,v2,v3,v4 a1,b1,c1,30,50,90,40 a3,b2,c4,30,70,50,90 result: f1,f2,f3,v1,v2,v3,v4 a1,b1,c1,80,110,160,120 a3,b2,c4,90,130,130,180 algorithm that we thought until now: hashing (using concurentHashTable) merge sorting the files DB: using mysql or hadoop or redis. The solution needs to be able to handle Huge amount of data (each file more than two million rows) a better example: file 1 country,city,peopleNum england,london,1000000 england,coventry,500000 file 2: country,city,peopleNum england,london,500000 england,coventry,500000 england,manchester,500000 merged file: country,city,peopleNum england,london,1500000 england,coventry,1000000 england,manchester,500000 The key is: country,city. This is just an example, my real key is of size 6 and the data columns are of size 8 - total of 14 columns. We would like that the solution will be the fastest in regard of data processing.

• GParted in UBUNTU shows entire disk as UNALLOCATED SPACE

  - by msPeachy

  Good day to everyone. I hope someone can help me with my problem. I have a dual boot Windows and Ubuntu system. I recently encountered an hd0 out of disk error and wasn't able to boot Ubuntu. So I booted into Windows, after 2 to 3 times of booting and rebooting Windows, I tried booting Ubuntu but still I get the hd0 out of disk error. I decided to run Ubuntu from LIVEUSB to try to fix my Ubuntu partition using GParted, but when I run GParted, it shows my entire disk as UNALLOCATED SPACE! The strange thing is that Nautilus still shows and mounts my partitions. Also every time I boot into Windows , my partitions exists and I am able to read and write to them. I have no idea what is wrong. Please help! I can't stand using Windows since most of the tools I use are in Ubuntu. I don't mind reinstalling Ubuntu. In fact I already tried reinstalling using the LIVEUSB but I wasn't able to, since GParted or the Ubuntu installer itself does not recognized my partitions and shows the entire disk as unallocated space. I am currently running Ubuntu from LIVEUSB. Here's the outpuf of sudo fdisk -l 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: 0xb30ab30a Device Boot Start End Blocks Id System /dev/sda1 * 2048 104869887 52433920 83 Linux /dev/sda2 104869888 105074687 102400 7 HPFS/NTFS/exFAT /dev/sda3 105074688 156149759 25537536 7 HPFS/NTFS/exFAT /dev/sda4 156151800 625153409 234500805 f W95 Ext'd (LBA) /dev/sda5 156151808 169156591 6502392 82 Linux swap / Solaris /dev/sda6 169158656 294991871 62916608 7 HPFS/NTFS/exFAT /dev/sda7 294993920 471037944 88022012+ 7 HPFS/NTFS/exFAT /dev/sda8 471041928 625121152 77039612+ 7 HPFS/NTFS/exFAT When I run, sudo parted -l, I got this error message: ubuntu@ubuntu:~$ sudo parted -l Error: Can't have a partition outside the disk!

• Why does a pdf file download result in varying bytes logged, all with sc-status 200

  - by Pat James

  I have a mojoportal CMS installation on an IIS7 server where users are reporting problems downloading a pdf file. It always downloads fine for me and most others, either displaying in browser or in Adobe Reader. Using logparser to query the IIS logs, all the responses are status 200 (OK) or 304 (Not modified), but the bytes sent vary quite a bit. Sometimes zero, some 211, some about half the full file size of 27059, and lots in between. Plenty show the full size of 27059. Do these other entries for smaller byte counts represent errors of some kind, correlating with the problems reported? Is this likely to be a browser/client issue or a server side problem? If there is any other info that would be helpful let me know. This is a shared hosting server though so I am somewhat limited in what I can dig into on the server.

• Drawing lines in 3D space

  - by DeadMG

  When attempting to draw a line in 3D space with D3DPT_LINELIST, then Direct3D gives me an error about an invalid vertex declaration, saying that it cannot be converted to an FVF. I am using the same vertex declaration and shader/stream setup as for my D3DPT_TRIANGLELIST rendering which works absolutely correctly. How can I use D3DPT_LINELIST to render some lines in 3D space? Edit: Oopsie, forgot my codeses. Here's my raw Draw call. D3DCALL(device->SetStreamSource(1, PerBoneBuffer.get(), 0, sizeof(PerInstanceData))); D3DCALL(device->SetStreamSourceFreq(1, D3DSTREAMSOURCE_INSTANCEDATA | 1)); D3DCALL(device->SetStreamSource(0, LineVerts, 0, sizeof(D3DXVECTOR3))); D3DCALL(device->SetStreamSourceFreq(0, D3DSTREAMSOURCE_INDEXEDDATA | lines.size())); D3DCALL(device->SetIndices(LineIndices)); PerInstanceData* data; std::vector<Wide::Render::Line*> lines_vec(lines.begin(), lines.end()); D3DCALL(PerBoneBuffer->Lock(0, lines.size() * sizeof(PerInstanceData), reinterpret_cast<void**>(&data), D3DLOCK_DISCARD)); std::for_each(lines.begin(), lines.end(), [&](Wide::Render::Line* ptr) { data->Color = D3DXColor(ptr->Colour); D3DXMATRIXA16 Translate, Scale, Rotate; D3DXMatrixTranslation(&Translate, ptr->Start.x, ptr->Start.y, ptr->Start.z); D3DXMatrixScaling(&Scale, ptr->Scale, 1, 1); D3DXMatrixRotationQuaternion(&Rotate, &D3DQuaternion(ptr->Rotation)); data->World = Scale * Rotate * Translate; }); D3DCALL(PerBoneBuffer->Unlock()); D3DCALL(device->DrawIndexedPrimitive(D3DPRIMITIVETYPE::D3DPT_LINELIST, 0, 0, 2, 0, 1)); Here's my vertex declaration: D3DVERTEXELEMENT9 BasicMeshVertices[] = { {0, 0, D3DDECLTYPE_FLOAT3, D3DDECLMETHOD_DEFAULT, D3DDECLUSAGE_POSITION, 0}, {1, 0, D3DDECLTYPE_FLOAT4, D3DDECLMETHOD_DEFAULT, D3DDECLUSAGE_TEXCOORD, 0}, {1, 16, D3DDECLTYPE_FLOAT4, D3DDECLMETHOD_DEFAULT, D3DDECLUSAGE_TEXCOORD, 1}, {1, 32, D3DDECLTYPE_FLOAT4, D3DDECLMETHOD_DEFAULT, D3DDECLUSAGE_TEXCOORD, 2}, {1, 48, D3DDECLTYPE_FLOAT4, D3DDECLMETHOD_DEFAULT, D3DDECLUSAGE_TEXCOORD, 3}, {1, 64, D3DDECLTYPE_FLOAT4, D3DDECLMETHOD_DEFAULT, D3DDECLUSAGE_COLOR, 0}, D3DDECL_END() }; The LineIndices are just 0, 1 and the LineVerts are just {0,0,0} and {1,0,0}, to represent a unit 3D line along the X axis.

  HI, We have ESXi cluster which is attached to clariion CX4 We have windows 2008 R2 as the guest OS. Attahed to this vm is 2 x 1.95T RDM's I select disk 1 create partition primary size=1 (1MB) then list partition Partition ### Type Size Offset * Partition 1 Primary 1024 KB 1024 KB Then I do the same for the other disk and offset is 1024KB I need to present 4T disk to this vm so I right click on disk 1 convert to simple volume then extend it by adding the second disk now when I do list partition, I see the off set is set to 31k. Can anyone please guide me. Thanks

• How to align text at the top left-hand corner?

  - by OverTheRainbow

  I'd like to use stylesheet instead of hard-coding HTML so that text within cells are aligned vertically, ie. text starts at the upper left-hand corner. However, neither of this works: <head> <link rel="STYLESHEET" href="display.css" type="text/css"> <style> td {vertical-align:top; font-size:x-small} td {vertical-align:text-top; font-size:x-small} </style> </head> Does someone know? Thank you. Edit: Problem solved. Turns out the HTML editor I'm using is a bit old and didn't display things as expected, but they do show OK in a modern browser with "vertical-align:top".

• How can I get something like Nautilus's "spatial" behaviour in 11.10 and later?

  - by Dylan McCall

  Until recently, Nautilus had an optional "spatial" mode as an alternative to its usual browser mode. Users could enable it by opening Nautilus's preferences and selecting "Open each folder in its own window." Choosing this option resulted in a stripped down interface, and folders would always open in the same place on the screen. It looked something like this: That checkbox is still there, but it doesn't do the same thing: while every folder opens in a new window, those windows are all the same size and positioned the same way. Nautilus doesn't restore the size and position of each folder, which is what spatial mode was all about. This difference really shows if someone opens a folder in a new window, and then opens the same folder again. Nautilus will create another window instead of focusing the existing window. I help someone who is currently using Ubuntu 10.04, and he will be upgrading to 12.04 in the future. He is very comfortable with Nautilus's spatial behaviour and I think he would be disappointed to lose it. Is there an alternative file manager, or perhaps some less obvious option, that will give him an interface similar to the one he is comfortable with?
