  • New keyboard for linux: Adesso Tru-Form or MS Natural Keyboard 4000?

    - by Andrea
    Hi folks! I'm going to buy a new ergonomic keyboard for my laptop. In the following, keep in mind I live in Italy. I considered the following models: Adesso PCK-308UB - Adesso Tru-Form™ Pro - Contoured Ergonomic Keyboard with TouchPad-PS2 Pro: has a built-in touchpad in the same position of my laptop somewhat cheaper than the alternative below Cons: the surface doesn't seem to be bowl-shaped. keys seem to lay on a straight slightly-inclined surface. It seems an idea used extensively in other ergonomic keyboards according to a few comments on the net, new Adesso keyboards seem to lack robustness, they're likely to loose small parts after a few weeks or months. Other users, instead, seem to never had any problem in years and swear by their quality and comfortability. Those who had problems, however, lamented a lack of responsiveness from the manufacturer. I'm not sure whether the keyboard, at least the standard keys, and the touchpad will both be recognized correctly under linux distros (I mostly use FC btw) last time I checked, Adesso didn't have local resellers in my country Microsoft Natural Ergonomic Keyboard Pro: recognized as one of the most comfortable keyboards reliable customer service operating in my country AFAIK there are several documented ways to get extra buttons work with linux Cons: it doesn't have a builtin touchpad and has a numeric keypad wasting space to reach mouse But there could be other keyboards I haven't considered yet, so here follows my ideal keyboard wishlist, ordered by priority linux compatible basic ergonomic design, which entails split tilted keyboard and pads advanced ergonomic design, like true-ergonomic's or kinesis , where special keys (like enter, caps-lock...) are placed symmetrically in the middle to be used by thumbs a builtin touchpad/trackball placed under the keyboard. I just love this on my notebook. I think it's pretty effective, since it allows my hand to rest naturally everytime I use it. Any opinion on this? high-quality switches, like cherry's (unsure about this one) additional programmable keys placed near usual ones, to simplify typing shortcuts TIA Andrea

  • How to deal with lots of brackets in a formula?

    - by wenlibin02
    Say, I have a formula like this (in LaTeX or Maple or other text system): Result: ((6*(k2+k3))*A123*k2*k3*(A12*A13*k2^2-2*A12*A13*k2*k3+A12*A13*k3^2-A123*k2^2-2*A123*k2*k3-A123*k3^2)*(exp(-k3*(k3^2*t-x)))^2+6*A12*(-k3+k2)*k2*k3*(A12*A13*k2^2-2*A12*A13*k2*k3+A12*A13*k3^2-A123*k2^2-2*A123*k2*k3-A123*k3^2)*exp(-k3*(k3^2*t-x)))*(exp(-k2*(k2^2*t-x)))^2+(-(6*(-k3+k2))*A13*k2*k3*(A12*A13*k2^2-2*A12*A13*k2*k3+A12*A13*k3^2-A123*k2^2-2*A123*k2*k3-A123*k3^2)*(exp(-k3*(k3^2*t-x)))^2-(6*(k2+k3))*k2*k3*(A12*A13*k2^2-2*A12*A13*k2*k3+A12*A13*k3^2-A123*k2^2-2*A123*k2*k3-A123*k3^2)*exp(-k3*(k3^2*t-x)))*exp(-k2*(k2^2*t-x)) Note: the above formula is only one part of the result of a maple calculation, I just can't break them up because there are so many many terms. Apparently, It's very hard to read. What I want to do is to fold the matched brackets level by level. If all the brackets are folded, I can find out clearly how many terms there are. Then I can analyze from the top level to the details of every term. But I just don't know how to realize that. Maybe there are some existed software which can visualize this kind of complex formula. Any idea? P.S. I use Linux system. The open source alternatives are better.

  • Numeric UIDs/GIDs in ACLs on OS X server (10.6)

    - by Oliver Humpage
    Hi, On one (old OS X 10.4) server I'm tarring up some files which have ACLs. I'm then using ``tar -xp'' to untar the archive onto a new 10.6 server, which doesn't have any users/groups configured on it yet except the default admin (UID 501) (there's a reason for that, don't ask!). Obviously this means an "ls -lne" will list files and ACLs with numeric UIDs and GIDs. Now for the normal file permissions it makes sense: you get UIDs like "1037". And for some ACLs, it also makes sense: you get things like "AAAABBBB-CCCC-DDDD-EEEE-FFFF00000402" for groups (0x402 = GID 1026) and "FFFFEEEE-DDDD-CCCC-BBBB-AAAA000001F5" for users (0x1F5 = UID 501). However, some ACLs have a UIDs like "E51DA674-AE70-41BC-8340-9B06C243A262" or GIDs like "0A3FCD24-0012-46FA-B085-88519E55EF29" and I have absolutely no idea how to translate these IDs back into something that could be matched back to the original IDs (UID 1072 and GID 1047 respectively in this example). Can anyone help me translate these weird long hex strings? (Basically we're moving from local users to an Active Directory setup, so I want to move all files to the new server with permissions intact, then chmod, chgrp and set ACLs such that we translate old IDs to the new AD IDs. Hence needing some way to map between the sets. I don't believe there's an easier way to do this?) Many thanks, Oliver.

  • Windows 7 - Windows XP - sharing - why isn't working?

    - by durumdara
    Hi! This is seems to be "hardware" and not "software" / "programming" question, but I need to use this share in my programs, so it is "close to programming". We had an XP based wireless network. The server is XP Professional, the clients are XP Home (Notebooks). This was working well with folder sharing (with user rights, not simple share). Then we replaced the one of the notebook with Win7/X64 notebook. First time this can reach the server, and the another client too. Later I went to another sites, and connect to another servers, another networks. And then, when I return to this network, I saw that I cannot connect to this server. Nothing of resources I see, and when try to dbl click on this computer, I got login window, where I can write anything, never I can login... The interesting part, that: Another XP home can see the server, can login as quest, or with other user. The server can see the XP home notebook. The Win7 can see the notebook's shared folders, and XP home can see the Win7 shared folders. The server can see the Win7 folders, BUT: the Win7 cannot see the server folders. Cannot see the resources too... The Win7 is in "work networking group", the group name is not mshome. I tried everything on the server, I tried to remove MS client, restore it with simple sharing, set guest password, etc., but I lost the possibilities to access this server from Win7. Does anyone have any idea what I need to see, what I need to set to access these resource - to use them in my programs? Thanks for every info, link: dd

  • What would keep a Microsoft Word AutoNew() macro from running?

    - by Chris Nelson
    I'm using Microsoft Office 2003 and creating a bunch of template documents to standardize some tasks. I know it's standard practice to put the templates in an certain place Office expects to find them but that won't work for me. What I want is to have "My Template Foo.dot" and "My Template Bar.dot", etc. in the "My Foo Bar Stuff" on a shared drive and users will double click on the template to create a new Foo or Bar. What's I'd really like is for the user to double click on the Foo template and be prompted for a couple of items related to their task (e.g., a project number) and have a script in the template change the name that Save will default to something like "Foo for Project 1234.doc". I asked on Google Groups and got an answer that worked....for a while. Then my AutoNew macro stopped kicking in when I created a new document by double clicking on the template. I have no idea why or how to debug it. I'm a software engineering with 25+ years of experience but a complete Office automation noob. Specific solutions and pointers to "this is how to automate Word" FAQs are welcome. Thanks.

  • Postfix connect timing out remotely, working fine locally

  • Windows 7 Media Center PC not displaying MKV files properly

    - by David
    Does anyone know why Windows Media Center wouldn't correctly display a 16x9 video? I just upgraded my home-built HTPC from Vista Ultimate (hey, it was a giveaway) to Windows 7 Ultimate - clean install. After that, I installed the Divx7 beta (to get .MKV support) and AC3filter (so I could HEAR the MKV files). Previously, under Vista Ultimate (32 bit), I had Arcsoft's Total Theater Pro for playing Blu-Rays and MKV decoding under Media Center. Now when I play a 720p 16x9 MKV file, I get some 'letterboxing' - like it's halfway between 4x3 and 16x9 - with the aspect ration looking alightly squished as a result. Here's the wierd part. If I use the Media Center connection software in my XBox 360 - it plays perfectly, filling the 16x9 screen edge-to-edge, just like Vista's WMC software USED to. Of course, beats the network up because the XBox goes to the HTPC, the HTPC goes to my WHS machine to fetch the data, it comes back to the HTPC, gets transcoded and streamed back to the Xbox. I'm running the latest drivers for an NVidia card (as fetched by Windows 7). I have no idea WHY this is because if I play "ordinary" (i.s. SD) Divx files that are 16x9, they play just fine, scaled right up to my screen's edges. It puzzles me as to why the same machine that properly converts the bits for the Xbox can't display/scale them properly for the attached display. Mind you, Windows Media Player exhibits the same symptoms. Ideas?

  • BGP Multipath & return routes

    - by Dennis van der Stelt
    I'm probably a complete n00b concerning serverfault related questions, but our IT department makes a bold statement I wish to verify. I've searched the internet, but can find nothing related to my question, so I come here. We have Threat Management Gateway 2010 and we used to just route the request to IIS and it contained the ip address so we could see where it was coming from. But now they turned on "Requests apear to come the TMG server" so ip addresses aren't forwarded anymore. Every request has the ip of the TMG server. Now the idea behind this is that because of multipath bgp routes, the incoming request goes over RouteA, but the acknowledgement messages could return over RouteB. The claim is that because the request doesn't come from the first known source, our proxy, but instead from IIS, some smart routers at the visitor of our websites don't recognize the acknowledgement message and filter it out. In other words, the response never arrives. Again, this is the claim. But I cannot find ANY resources on the internet that support this claim. I do read about bgp multipath, but more in the case that there are alternative routes when the fastest route fails for some reason. So is the claim completely bogus or is there (some) truth to it? Can someone explain or point me to resources? Thanks in advance!

  • Linux: Managing users, groups and applications

    - by RN
    I am fairly new to linux admin so this may sound quite a noob question. I have a VPS account with a root access I need to install Tomcat, Java on it and later other open source applications as well. Installation for all of these is as simple as unzipping the .gz in a folder. My questions are A) Where should I keep all these programs? In Windows, I typically have a folder called programs under c:\ where I unzip all applications. I plan to have something similar here as well. Currently, I have all these under apps folder under/root- which I am guessing is a bad idea B) To what group should Tom belong to ? I would need a user - say Tom who can simply execute these programs. Do I need to create a new group? or just add Tom to some existing group ? C) Finally- Am I doing something really stupid by installing all these application by simply unzipping them? I mean an alternate way would be to use Yup or RPM or something like that to install these applications. Given my familiarity and (tight budget) that seems too much to me. I feel uncomfortable running commands which i don't understand too well

  • Terminating multi-mode fiber

    - by murisonc
    I'm looking at the feasibility of terminating multi-mode fiber connections ourselves. We would be using LC connectors. I've done some research and found two different methods. One requires polishing the ends and using epoxy while the other doesn't. I like the idea of not having to polish the ends but there doesn't seem to be much information on quality or ease of use. I've found two vendors (3M and Corning) that offer kits for terminating fiber without polishing or using epoxy. Does anyone have any experience with both methods that can offer some advice? Copper is easy but fiber seems to be a whole different animal. EDIT: After looking into fusion splicing suggested in the answer I've determined it's not for us. It's my understanding that is primarily used for outside plant and is better suited for single mode fiber. It's a good answer but doesn't address the question directly. Some more information about our situation. We will only be terminating multi-mode fiber inside a building and only doing between 4 and 20 pair a year. Hiring an outside person won't work due to our location. There are currently a couple people on-site that can terminate fiber (working for another company and charging large fees) but they can only do ST and SC connectors and we only use LC. So once again does anyone have experience with terminating using both epoxy type connectors and the other type (similar to Corning Unicam)?

  • Replacing local home server with VPS: Suggestions?

    - by CamronBute
    So right now, I'm running an old box with a 2TB HDD in it. I use this as a file server for the home network, as well as a box for downloading large files which are synced via Dropbox. Lots of other tinkering things, too. Basically, I'm sick of paying extra for the power and having to worry about drive failures and whatnot. I'd rather get a remote server, let someone else manage it and provide access from the Internet. So, I've been looking for a Windows VPS that would give me access to install things and tinker, and I'm having a problem finding a host that offers more than 100GB of hard drive space. If they do offer a package with 100GB of storage, everything else is waaayyyy more than what I actually need. The idea is to create a permanent VPN connection from the cloud server to my home network to provide a transparent solution so I'm not having to go to lengths to transfer files or whatnot. I think a VPS solution will allow me to do this. I would like 1TB of storage space, minimum 100Mbps Internet connection, minimum 250GB bandwidth, admin access. Anyone have anything? Or am I being unreasonable? If I am, why?

  • mpirun -np N, what if N is larger than my core number?

    - by Daniel
    Say I have a 4-core workstation, what would linux (Ubuntu) do if I execute mpirun -np 9 XXX Q1. Will 9 run immediately together, or they will run 4 after 4? Q2. I suppose that using 9 is not good, because the remainder 1, it will make the computer confused, (I don't know is it going to be confused at all, or the "head" of the computer will decide which core among the 4 cores will be used?) Or it will be randomly picked. Who decide which one core to call? Q3. If I feel my cpu is not bad and my ram is okay and large enough, and my case is not very big. Is it a good idea in order to fully use my cpu and ram, that I do mpirun -np 8 XXX, or even mpirun -np 12 XXX. Q4. Who decides all of these effciency optimization, Ubuntu, or linux, or motherboard or cpu? Your enlightenment would be really appreciated.

  • apache permission errors

    - by Wilduck
    I'm trying to set up Apache on a arch-linux box as a testing environment (I'm only using the localhost, not trying to serve anything to the greater web). When setting up Django with mod_wsgi, it recommended that I set up a WSGIScriptAlias from / to /usr/local/django/mysite/apache/django.wsgi . I've done this, as well as added the /usr/.../apache directory to my httpd.conf. When I try to access http://localhost I get a 403 forbidden error. I have no idea why this is happening. Things I've tried so far: 1) chown -R http .../apache 2) chmod -R 777 .../apache 3) using a simple Alias directive to host a static file from that directory. None of these have worked. I'm at a loss for what I'm doing wrong. Below is a relevant excerpt from my httpd.conf: Alias / /usr/local/django/mysite/apache <Directory "/usr/local/django/mysite/apache"> Order deny,allow Allow from all </Directory> So my question is: what am I doing wrong?

  • Toshiba laptop cd drive read causes OS to totally freeze

    - by Fujishiro
    Okay I'll try to write an understandable summary. Forgive me if I'll fail with that attempt though. So. There is a Toshiba Satellite notebook. Got Windows 7 x86 Professional (OEM) installed on it, everything is fine (okay.. somewhat). The problem. If you put an audio or any kind of disc into the drive, something starts to eat the PC. Back then when the owner told me about this, he put an audio disc into the lappy. Winamp caused the IO load, 100%. Tried taskkill, taskkill /T, tried powershell, EVERYTHING. You just can NOT kill winamp or anything which becomes the blocker at that time. Even if you kill almost everything, laptop won't do a clear shutdown. Also I tried to use the force switch at 'shutdown' from cmd, but no use. (So: At these times you can use the laptop, but the blocker/explorer/disc becomes gray as a non-responding app. You can try to kill them, but that won't work, nor you can shutdown the machine). (Also tried using PID, but no use. For the highest IO I used the "select columns" from Task Manager and enabled the IO columns.) My first hunch was the problematic disc, autoplay and it tries to read tries to read (still shouldn't kill the PC). Disabled autoplay, removed winamp. Tried other software, etc. Everything was ok. Few days later the owner tried to put a disc into the machine and it started to reproduce the same symptoms but with a totally different disc. Uhm what to know. Virus is not an option, protected by BitDefender (valid license) and Spybot. Thanks if you have ANY idea about this strange problem. ps.: For now, the owner uses Daemon tools + Blindwrite as an alternative for those apps which wouldnt start without the disc.

  • Windows Server 2008 R2 DNS - One IP, multiple servers

    - by Blu Dragon
    I need opinions and examples on how to best to accomplish the setup I am looking for. I have a public-facing AD domain server with one public IP address. I have setup an external zone for example.com and I successfully have my own name servers pointing to it at ns0.example.com and ns1.example.com. I also have an internal zone for my private network at home.example.com. I am behind a router with the domain server in the DMZ. I want dev.example.com to be accessible from the outside world over https and to point to internal IP address 192.168.1.78. Likewise, I want www.example.com to be accessible from the outside world and point to internal IP address 192.168.1.79. Both dev and www servers are CentOS 5.6 VMs running inside of Hyper-V on the domain server (bad idea I know but I am limited on hardware atm). What is best way to achieve this? From what I have read and researched on Google, I may need to setup a reverse proxy but I am not sure how well that will work with SSL.

  • iconv supports too few encoding

    - by schemacs
    iconv -l outputs too few encodings on CentOS 6.5: $ iconv -l 10646-1:1993, 10646-1:1993/UCS4, ANSI_X3.4-1968, ANSI_X3.4-1986, ANSI_X3.4, ASCII, CP367, CSASCII, CSUCS4, IBM367, ISO-10646, ISO-10646/UCS2, ISO-10646/UCS4, ISO-10646/UTF-8, ISO-10646/UTF8, ISO-IR-6, ISO-IR-193, ISO646-US, ISO_646.IRV:1991, OSF00010020, OSF00010100, OSF00010101, OSF00010102, OSF00010104, OSF00010105, OSF00010106, OSF05010001, UCS-2, UCS-2BE, UCS-2LE, UCS-4, UCS-4BE, UCS-4LE, UCS2, UCS4, UNICODEBIG, UNICODELITTLE, US-ASCII, US, UTF-8, UTF8, WCHAR_T But on my Ubuntu the list seems much longer, here is different: CentOS6.5: $ php -a php > echo iconv('utf8', 'gbk', 'abc'); PHP Notice: iconv(): Wrong charset, conversion from `utf8' to `gbk' is not allowed in php shell code on line 1 php > quit $ php -i|grep iconv iconv iconv support => enabled iconv implementation => glibc iconv library version => 2.12 iconv.input_encoding => ISO-8859-1 => ISO-8859-1 iconv.internal_encoding => ISO-8859-1 => ISO-8859-1 iconv.output_encoding => ISO-8859-1 => ISO-8859-1 Ubuntu 14.04: $ php -a Interactive mode enabled php > echo iconv('utf8', 'gbk', "abc\n"); abc php > quit $ php -i|grep iconv iconv iconv support => enabled iconv implementation => glibc iconv library version => 2.19 iconv.input_encoding => ISO-8859-1 => ISO-8859-1 iconv.internal_encoding => ISO-8859-1 => ISO-8859-1 iconv.output_encoding => ISO-8859-1 => ISO-8859-1 But I don't want to recompile glibc(this will be huge mount of work), any idea on how to ad new encoding support?

  • Archive software for big files and fast index

    - by AkiRoss
    I'm currently using tar for archiving some files. Problem is: archives are pretty big, contains many data and tar is very slow when listing and extracting. I often need to extract single files or folders from the archive, but I don't currently have an external index of files. So, is there an alternative for Linux, allowing me to build uncompressed archive files, preserving the file attributes AND having fast access list table? I'm talking about archives of 10 to 100 GB, and it's pretty impractical to wait several minutes to access a single file. Anyway, any trick to solve this problem is welcome (but single archives are non-optional, so no rsync or similar). Thanks in advance! EDIT: I'm not compressing archives, and using tar I think they are too slow. To be precise about "slow", I'd like that: listing archive content should take time linear in files count inside the archive, but with very little constant (e.g. if a list of all the files is included at the head of the archive, it could be very fast). extraction of a target file/directory should (filesystem premitting) take time linear with the target size (e.g. if I'm extracting a 2MB PDF file in a 40GB directory, I'd really like it to take less than few minutes... If not seconds). Of course, this is just my idea and not a requirement. I guess such performances could be achievable if the archive contained an index of all the files with respective offset and such index is well organized (e.g. tree structure).

  • Configuring WPA WiFi in Ubuntu 10.10

    - by sma
    I am trying to configure my wireless network on my laptop running Ubuntu 10.10 and am having a bit of difficulty. I am a complete Linux newb, but want to learn it, hence the reason I'm trying to set this up. Here's the vitals: It is a Gateway 600 YG2 laptop. It was previously running Windows XP, but I installed Ubuntu 10.10 in place of it (not a dual boot, I removed XP altogether). I have an old wireless card that I'm trying to resurrect. I haven't really used the card in a couple years, but it seems to still work, I just can't connect to my home's wireless network. The card is a Linksys WPC11 v2.5. When I plug it in, Ubuntu recognizes the network, but won't connect to it. My home network uses WPA encryption and the only connection type that Ubuntu's network manager is giving me is WEP and then it asks for a key -- I have no idea what that key should be. So, basically, I'm asking, is there a way I can instead connect through WPA? I've tried creating a new connection in network manager, but that won't work, it keeps falling back to the WEP connection and asking me for a key. I have tried to install the XP driver using ndiswrapper but I don't know if that's working or not. Is there a way to tell if: A) the card is working as it should B) the correct drivers are installed (again, I installed the XP one using ndiswrapper NET8180.INF, but I'm not sure what to do next) Any help would be appreciated. Thank you.

  • Ubuntu 10.04 server delay responding to AJAX requests

    - by DanielAttard
    I manage a Ubuntu 10.04 server with a couple of domains hosted on it. As I continue to learn more about all these wonderful new (for me), one issue that I have begun to notice is the delay it sometimes takes for the server to respond to certain requests. As an example, when I view the timeline of events using firebug I can see that most of the time when I make a POST, the server responds in under 100ms. Sometimes, however, there is a substantial delay before the RESPONSE from the server. I can't seem to tell when the delay will happen and when it won't, however, when it happens the delay is always for about 4.5 seconds. The delay seems to happen about 30-40% of the time. Here is the section of apache2.conf dealing with logs: # # The following directives define some format nicknames for use with # a CustomLog directive (see below). # If you are behind a reverse proxy, you might want to change %h into %{X-Forwarded-For}i # LogFormat "%v:%p %h %l %u %t \"%r\" %>s %O \"%{Referer}i\" \"%{User-Agent}i\"" vhost_combined LogFormat "%h %l %u %t \"%r\" %>s %O \"%{Referer}i\" \"%{User-Agent}i\"" combined LogFormat "%h %l %u %t \"%r\" %>s %O" common LogFormat "%{Referer}i -> %U" referer LogFormat "%{User-agent}i" agent I have no idea where to look to try and debug this problem or investigate further. Any suggestions?

  • How do I set up DNS with nic.io to point to an AWS EC2 server?

    - by Chad Johnson
    I purchased a domain one week ago via nic.io. I have elected to provide my own DNS [because they provided no other option]. I'm trying to point my .io domain at my EC2 server instance. I've allocated an elastic IP and associated it with the instance. I can SSH into the instance and access point 80 via the IP address just fine. The IP is 54.235.201.241. nic.io support said the following: "You have selected to provide your own DNS and therefore if there is an issue with the set-up of the name servers you will need to contact your DNS provider." So, I created a Hosted Zone via Route 53 in AWS. This created NS and SOA records. I then set the Primary and Secondary servers at nic.io's domain admin page to the SOA record domains. Additionally, I set the optional servers to the NS domains. I did this two days ago, and I can't access the server via the domain. I ran a DNS check here...still not sure what I need to do: http://mydnscheck.com/?domain=chadjohnson.io&ns1=&ns2=&ns3=&ns4=&ns5=&ns6=. I have no idea what I'm supposed to do. Does anyone have any ideas?

  • RRAS NAT not working on a certain computer

    - by legenden
    This is driving me crazy. I have a virtualized W2K8 server running RRAS. Every other computer or server on the network can access the internet through the NAT except one. On one server, it just won't work. I can ping the ip address of the NAT gateway just fine, and everything else works. (SMB, etc) DNS, which is hosted by the same server, also works just fine. I have even reinstalled the OS on the problem server and it still doesn't work. Recap of the steps I tried: There are 3 network cards in the server, I tried every one and different switch ports. Not a hardware problem. Reinstalled W2K8 R2 on server with the problem, didn't help. Tried the IP of the internet gateway directly - this did work (!). But I need NAT to work. All firewalls are disabled. Removed computer from domain, deleted computer membership in Active Directory Users and Computers and added it back. Disabled all other network adapters and set a static ip and specified the gateway ip manually. When I tracert a public IP, the first hop (or any other hop) comes up as: C:\>tracert www.google.com Tracing route to www.l.google.com [209.85.225.106] over a maximum of 30 hops: 1 * * * Request timed out. 2 * * * Request timed out. From a different computer, on which NAT works, the first hop comes up as: tracert www.google.com Tracing route to www.l.google.com [209.85.225.105] over a maximum of 30 hops: 1 <1 ms * <1 ms xxxx [10.5.1.1] This is the most bizarre problem I ever came across, and I realize that it's a long shot asking it here given all the details, but I'm pulling my hair out. Maybe someone has an idea...
