  • Taking too long to get skills for entry level programmer position [closed]

    - by greenonion
    I don't have the skills for an entry level position as a .Net programmer. I am trying to learn what I need but there is too much to learn and too little time. What can I do? About two months ago, I went to a job interview for an entry level C# .Net programming/consultant position in NYC. When I heard back from them, they told me that the knowledge gap between what I knew and what they needed me to know was too big and I might have been a better fit if I had 6 months of experience. This was the first interview that I went on since graduating college. before the interview, I read a book on visual C#. Turns out it wasn't a very good book and I was missing a lot of key areas of knowledge such as ADO.net SQL (I had learned some LINQ) A little bit about how memory is handled Multiple threaded programming, etc. Because the book wasn't very good, the stuff I did know, I didn't know very well. I felt crushed. I've applied for jobs to gain experience but when recruiters hear that I have no experience they lose interest. I figured that I can at least work on my knowledge. Since then, I read "SQL Essentials" to cover the SQL bit and I found a pretty awesome book that is good enough to clear up what's hazy in my mind and covers almost all of the extra topics. The book is "C# 4.0: The Complete Reference" by Herbert Schildt. I'm even learning a lot about the topics I was familiar with. For a month now I've been working my way through this beast of a book. However, gaining the knowledge I need is taking too long. I can't hold off not having a full-time job much longer. I'm not stupid and I'm studying constantly pouring through the book, asking questions on stackoverflow, referencing the C# specification, etc. I have made great progress but there is just too much ground to cover. I'm on chapter 12 which is about a 3rd through the book. To get an idea of what I know vs don't know, the table of contents is on amazon: http://www.amazon.com/C-4-0-The-Complete-Reference/dp/007174116X How on earth can someone know enough to function as a programmer in the real world? Can I try for a job in academia? Will I have time to finish learning the rest of the C# language or am I just un-hireable?

  • Goldtouch USB Keyboard reverses keystrokes in fast typing -- expected?

    - by Justin Grant
    I am running into an odd keyboard problem: some key combinations end up reversed (e.g. "pl" ends up being emitted as "lp") when I'm typing quickly. The problematic ones are the key combos I hit with two adjacent fingers on my right hand-- in other words, the combos I can hit the fastest. No idea how fast is "fastest", but I guess around 50-150 msecs gap between them. I'm trying to track down whether this represents a failed keyboard, an inherent limitation of my Goldtouch USB keyboards, or a software problem on my Windows 7 Lenovo T500. I use a PS/2 version of the same Goldtouch keyboard at home with no problems. I've tried another USB keyboard with my laptop and can't repro the problem. I've also used this keyboard on other laptops without a problem. According to this SU thread, USB keyboards have higher latency than PS/2 keyboards-- up to 30 msecs. I find it hard to imagine that I can type key combos faster than 50 msecs, probably more like 100-150. Anyone encountered this problem with this or another keyboard? If so, how did you fix it? Any idea if there's a "keyboard log" or some way to diagnose the problem inside Windows?

  • Distributed development staff needing a common IP range

    - by bakasan
    I work on a development staff that is geographically distributed, mostly all throughout the state of CA, but several key members also must travel frequently. We rely quite heavily on a 3rd party provider API for a great deal of our subsystems (can't get into who it is or what they do). The 3rd party however is quite stringent on network access and have no notion of a development sandbox. Access is restricted to 2, 3 IP numbers and that's about it. Once we account for our production servers, that leaves us with an IP or two to spare for our dev team--which is still problematic as people's home IP changes, people travel, we have more than 2 devs, etc. Wide IP blocks are not permitted by the 3rd party. Nor will they allow dynamic DNS type services. There is no simple console to swap IPs on the fly either (e.g. if a dev's IP at home changes or they are on the road). As none of us are deep network experts, I'm wondering what our viable options are? Are there such things as 3rd party hosts to VPNs? Generally I think of a VPN as a mechanism to gain access to a home office, but the notion would be a 3rd party VPN that we'd all connect to and we'd register this as an IP origin w/ our 3rd party. We've considered using Amazon EC2 to effectively host a dev environment for each dev and using that to connect. Amazon only gives you so many static IPs however (I believe 5?) so this would only be a stop gap solution until our team size out strips our IP count at Amazon. Those were the only viable thoughts that I had, but again, I'm far from a networking guy. Tried searching for similar threads, but I'm not even sure I know the right vernacular to look around for.

  • Server Performance

    - by sb12
    I know very little about performance tuning of servers etc... so i thought i'd put this up here as i start some research on it, just to get some direction. I am in the process of migrating from my old server to a new one - both are 64 bit machines. One is a few years old, the other brand new (PowerEdge R410). The old server spec is: 2 cpus, 3.4GHz Pentiums, 8G of RAM, Fedora 11 currently installed The new server spec is: 16 cpus, 3.2 GHz Xeon, 16G of RAM, CentOS 6.2 installed. Also RAID10 is on the new server - no RAID on the old one. Both servers currently have the same database (MySQL) with the same data migrated. I wrote a Perl script that simply steps through each row of a table in the database (about 18000 rows) and updates a value in that row. Every row in the table is updated. Out of curiosity i ran this perl script on both machines, just to see how the new server would perform vs. the old one, and it produced interesting results: The old server was twice as fast as the new one to complete. Looking at the database, both are configured exactly the same (the new one being a dump of the old one...)... Anyone any ideas why this would be given the hardware gap between both? As i said i'm about to start some digging, but thought i'd put this up here to maybe get some good direction.... Many thanks in advance..

  • Could this server log mean my server is being used as a proxy?

    - by So Over It
    I came across the following entry in my access.log: 58.218.199.147 - - [05/Jun/2012:12:56:04 +1000] "GET http://proxyproxys.com/ HTTP/1.1" 200 183 "-" "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1)" Normally when I see a full URL entry in my access.log I assume it is log spam with people trying to get me to access their site. These entries are normally followed with a 404 response. The above entry is followed with a 200 'success' response! Doing some searching it would seem that this can occur when someone is trying to use your server as a proxy. This disturbed me more - especially because the URL in question has the word proxy in it. Going to the site 'proxyproxys.com' (using hidemyass.com to protect my own identity), the site returns what appears to be some sort of 'proxy judge' ---------------------------------------- HTTP_ACCEPT=text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8 HTTP_ACCEPT_LANGUAGE=en-US,en;q=0.8 HTTP_USER_AGENT=Mozilla/5.0 (Macintosh; Intel Mac OS X 10_7_4) AppleWebKit/536.5 (KHTML, like Gecko) Chrome/19.0.1084.53 Safari/536.5 HTTP_CONNECTION=close REMOTE_PORT=56355 REMOTE_HOST=74.63.112.142 REMOTE_ADDR=74.63.112.142 ---------------------------------------- CS_ProxyJudge Result=HIGH_ANONYMITY ---------------------------------------- Question: 1) does the 200 success mean that someone has been able to successfully use my server as a proxy? 2) are there other means of confirming if my server is being used as a proxy 3) can you refer me to documentation to help 'close up' my security gap if there is one. Thanks.

  • Best way to mount 3-4 monitor like this?

    - by jasondavis
    I just purchased 2 HP 2009m widescreen monitors, they are not the biggest thing on the block, they are like 19-20" and are only around 150-200$ so I think they are perfect. I bought 2 of them just to make sure I like them, with the full intention of purchasing more to make either a tripple or quad display. I now I am stuck trying to decide, if I purchase 1 more to have a tripple display I would then like to just wrap the third monitor to either the rigth or left side, I could do this without a mount most likely pretty easy. If I decide to go with 2 more monitors to make a quad display then I would like to add the 2 new monitor directly above the 2 that I have now. So it would make a grid of 2 wide and 2 high. I have posted a few photos belwo to show them now with the 2 I have, you will notice that I have them tilted inwards to make more of a "V" shape instead of them being side by side and "STRAIGHT". Now if I decide to make thegrid of 4 then I will need to buy or build a stand to hold them all tightly together (no whitespace or gap between the grid of monitors) but I would like to still have both rows invert to make the slight "V". Do you know of any existing stands I could purchase that would hold all 4 monitors without making them be STARIGHT without the "V" shape? Any tips appreciated please, also they do have holes in the back for VESA. a few photos... (they are from iphone and lighting made them note very good but you can see what I am working with here)

  • Server hang - data loss on reboot, post mortem analysis

    - by rovangju
    A development server I'm responsible for (ext3 on raid 5 w/Debian Squeeze) froze up over the weekend and I was forced to reset it, as in unresponsive from KVM/physical keyboard access, no eth devices responding, etc. Not even the backup process ran (Figures, the one time I don't check for confirmation) So after the reset, it turns out that every trace of disk IO activity that should have happened for a period of ~24H is completely gone. The log files have a big gap in the dates and times. As if the writes were never committed to disk, no processes seemed to have run. Luckily it was a weekend and nothing of value would have been lost and I don't suspect a hack. What can I do in post mortem to this event - to prevent it from ever happening again? I've seen this happen before on a completely different machine running FreeBSD. I am rounding up the disk checking tools right now - but there must be more going on! Mount options: /dev/sda1 on / type ext3 (rw,errors=remount-ro) Kernel: Linux dev 2.6.32-5-686-bigmem Disk/Inodes: 13%/3%

  • Cooling Server Closet - No A/C Is Possible

    - by JamesCo
    We're moving into a new office in an old building in London (that's England :) and are walling off a 2m x 1.3m area where the router & telephone equipment currently terminates to use as a server closet. The closet will contain: 2 24-port switches 1 router 1 VSDL modem 1 Dell desktop 1 4-bay NAS 1 HP micro-server 1 UPS Miscellaneous minor telephony boxes. There is no central A/C in the office and there never will be. We can install ducting to the outside quite easily - it's only a couple of metres to the windows, which face a courtyard. My question is whether installing an extractor fan with ducting to the window should be sufficient for cooling? Would an intake fan and intake duct (from the window, too) be required? We don't want to leave a gap in the closet door as that'll let noise out into the office. If we don't have to put a portable A/C unit into the closet, that'd be perfect. The office has about 12 people; London is temperate, average maximum in August is 31 Celsius, 25 Celsius is more typical. The same equipment runs fine in our current office (same building as new office, also no A/C) but it isn't in an enclosed space. I can see us putting say one Dell 2950 tower server into the closet, but no more than that. So, sustained power consumption in the closet would currently be about 800w (I'm guessing); possibly in the future 2kw. The closet will have a ceiling and no windows and be well-insulated. We don't care if the equipment runs hot, so long as it runs and we don't hear it.

  • Using AddEncoding x-gzip .gz without actual files

    - by STATUS_ACCESS_DENIED
    With Apache (2.2 and later) how can I achieve the following. I want to transparently compress using GZip encoding (not plain Deflate) the output when a certain file is queried with its name plus the extension .gz, where the .gz version doesn't physically exist on disk. So let's say I have a file named /path/foo.bar and no file foo.bar.gz in the folder to which the URI /path maps, how can I get Apache to serve the contents of /path/foo.bar but with AddEncoding x-gzip ... applied to the (non-existing) file? The rewrite part appears to be easy, but the problem is how to apply the encoding to a non-existent item. The other way around also seems to be simple as long as the client supports the encoding. Is the only solution really a script that does this on the fly? I'm aware of mod_deflate and mod_gzip and it is not what I'm looking for - at least not alone. In particular I need an actual GZIP file and not just a deflated stream. Now I was thinking of using mod_ext_filter, but couldn't bridge the gap between rewriting the name of the (non-existent) file.gz to file on one side and the LocationMatch on the other. Here's what I have. RewriteRule ^(.*?\.ext)\.gz$ $1 [L] ExtFilterDefine gzip mode=output cmd="/bin/gzip" <LocationMatch "/my-files/special-path/.*?\.ext\.gz"> AddType application/octet-stream .ext.gz SetOutputFilter gzip Header set Content-Encoding gzip </LocationMatch> Note that the header for Content-Encoding isn't really needed by the clients in this case. They expect to see actual GZIP files, but I want to do this on-the-fly without caching (this is a test scenario).

  • VoIP setup for one external PSTN line

    - by Jcl
    I'm completely new to VoIP and the likes, and I'm trying to find information about what could be the best setup for this. I need 4 (maybe more in the future, but maximum 5 or 6) wireless extensions, connected to 1 PSTN line, and maybe 2 in the future. I've been trying to gather information about the gear needed but everything I find seems too much over-the-top (and extremely expensive). The main problem is that the physical place we are on doesn't have possibilities of having a decent internet connection, so using a external VoIP "virtual PBX" is not an option. Thing is, even if small, phone is critical to this organization. I currently have an analog DECT/GAP PBX which does what I need, however the PBX is very bad and the call quality is horrible, and that's why I want to change it. The requirements would be: 4 wireless terminals (routing cable is not an option), all of them ringing on incoming PSTN calls. Ability to do internal calls (4 separate offices) and ability to pass calls between terminals. The 4 terminals should be able to access the external PSTN line without dialing any special codes. Very important: terminals should be able to issue commands on the PSTN line to the external operator in the form *nn*nnnnnnnn# . Don't know wether this could face to be a problem, but I've had problems with analog PBX which would take any * as a PBX command and wouldn't allow terminals to send it to the external lines. Not so important, but would be nice to have: call waiting music Could anyone recommend such a setup? I need to be able to do this on a EXTREMELY LIMITED budget (that is: I don't have a limit, but all should get as much to zero as possible). I have enough spare powerful computers and a 300mbps wireless network which works just fine, so that's not to include in the budget. Don't really know if this is the best place to ask, but it's the most StackExchange-related site I've found to this subject.

  • Two DHCP servers on the same network

    - by CesarGon
    We are setting up a routing link between the Windows Server 2008 networks of two different buildings in my organisation. Each network uses a different IP addressing scheme (one uses public addresses, the other one uses private), but the goal is having a single Windows Server domain across the gap between the buildings. The link is provided by a 100-Mbps point-to-point line. I have always understood that you should not have more than one DHCP server on a network. However, we are planning to put a domain controller on each building, and each domain controller will be a DNS server and a DHCP server as well. The intention is that a machine booting up in building A gets its IP address from the DHCP server closer to it, in building A, while a machine booting up in building B gets an address from the DHCP server in building B. Since the two buildings will be linked and the network will be only one, will this work? How can I avoid that a machine booting up in building A gets an address from the DHCP server in building B (or vice versa)? Thanks.

  • Merging cuesheet chapter halves into single track for an audiobook

    - by TheSavo
    I have an audiobook that I have ripped and I need some help constructing chapters. I have already made some cue sheets TITLE "Bookname" PERFORMER "the Author" FILE "File1.FLAC" wave ; 23971906.667 milliseconds TRACK 01 AUDIO TITLE "_Intro" INDEX 01 00:00:00 TRACK 02 AUDIO TITLE "CH 01" INDEX 01 24:15:50 TRACK 03 AUDIO TITLE "CH 02" INDEX 01 66:21:00 TRACK 04 AUDIO TITLE "CH 03" INDEX 01 87:05:00 The audio book is in two files. The chapter at the end of the first file is continued in the second file. However, the second file restates: The publisher Book Title List item Blah blah blah I would like to merge the two 'halves' of the chapter in one seamless track. The only way I can think to do this would be be: Bulk cut down the tracks. Drop the junk info into junk track Continue the track listings as normal Take the two "halves" of the target chapter and build a separate cue sheet for it. I know there has to be an easier way. I am ok with making the 'junk' info a 'gap' or something. These are are FLAC files that will be converted to MP3 for my phone and other potable devices. I have read the primers on cue sheets, but I am just not getting it.

  • Unexplained cache RAM drops on Linux machine

    - by FunkyChicken
    I run a CentOS 5.7 64 machine with 24gb ram and running kernel 2.6.18-274.12.1.el5. This machine runs only Nginx, php-fpm and Xcache as extra applications. Since about 3 weeks my memory behavior on this machine has changed and I cannot explain why. There are no crons running which flush anything like this. There are also no large numbers of files being deleted/changed during these drops. The 'cached' memory gets dropped about every few hours, but it's never a set gap between flushes, this indicates to me that some bottleneck gets reached instead. It also always seems to be when total memory usages gets to about 18GB, but again, not always exactly 18GB. This is a graph of my memory usage: As you can see in the graph the 'buffers' always stay more or less the same, it is mainly the 'cache' that gets dropped. Running vmstat -m I have outputted the memory usage just before and just after a memory drop. The output is here: http://pastebin.com/diff.php?i=hJqZqztm 'old version' being before, 'new version' being after a drop. About 3 weeks ago my server crashed during a heavy DDOS attack, after I rebooted the machine this odd behavior started. I have checked a bunch of logs, restarted the machine again, and cannot find any indication what changed. During these 'cache' memory drops, my iNode usage drops at the same time. Does anyone have any idea what might be causing this behavior? Clearly my RAM isn't full, so I am curious why this could be happening.

  • load average in top and procs in vmstat

    - by Mingfei.hua
    As far as I know, the load average in top is the numbers of precess(threads) in running or uninterrupted sleep status, So it should be equal to (procs-r +1 )+ procs-b in vmstat, but in practice, this two number always have big gap.

  • Making it Easier for Older Users to Login to Multiple Accounts

    - by Mike Hagstrom
    I currently do consulting for a small business that has multiple applications that they need to login too. I'm trying to get them to start using Basecamp and Zendesk to make all of our lives easier when it comes to collaboration on big projects and quick helpdesk ticket items. However, I have recently been informed that it is difficult for them to remember all of these websites etc... to login too. However the login information is the same. Right now they have to login to: Windows Login Gmail I want them additionally to login to Basecamp Zendesk This is just a generation or two gap between myself and them, so I'm wondering what others do to solve these problems. Is there some way we could configure USB thumbdrives that somehow have Lastpass or something on that when plugged into the computer automatically log them into their Windows account, then when they were to say visit the Basecamp account would automatically log them into that? I think the security risk (of a list thumbdrive) is well worth the ability to use these extra applications. Unless anyone else has any other ways for making it easier for users to login to multiple sites.

  • Windows drive letters A: and B:

    - by Workshop Alex
    This is a question that just popped into my mind and I can't help but wonder why it's still common for a Windows installation to be installed on C: with all other drive letters going up from D: to Z:. In the early MS-DOS times, all we had were floppy disks and they were at A:. When the 3.5 inch floppy started to replace the 5.25 floppy, many people had an A: and B: drive. Then the hard disk became popular and the hard disk was at C: because A: and B: were taken. Then the 5.25 floppy disappeared and most computers had a gap between A: and C:. Nowadays, the 3.5 floppy is just too outdated so A: disappeared too. All disks now start at C:. Yeah, I know I can assign my own drive letters and I've done so with my data disks. My installation disk will just continue to be stuck at C: and I don't really mind. I have no problems with drive letters. But why do the new Windows versions just continue to install themselves by default on C: instead of assigning the letter A: to the boot hard disk?

  • When modern computers boot, what initial setup of RAM do they execute, and how does it exactly work?

    - by user272840
    I know the title reeks of confusion, and some of you might assume I am just wondering about how the computer boots in general, but I'm not. But I'll sort this out for you people now: 1.Onboard firmware is how mostly all modern computer devices work, whether or not with EFI/UEFI(even without "onboard firmware", older computers still employed bank switching, or similar methods with snap-in firmware, cartridges, etc.) 2.On startup there is no "programs" running in the traditional sense yet, i.e. no kernel, OS, user-applications; all of the instructions, especially the very first instruction, is specified by the Instruction Pointer, I am guessing. How is the IP/PC/etc. set to first point to an address for a BIOS/firmware/etc. instruction, and how do the BIOS instructions map themself out in memory prior to startup? 3.Aside from MMIO, BIOS uses certain RAM addresses to have instructions. The big ? comes in when I ask this ... how does BIOS do this? Conclusion: I am assuming that with the very first instruction there is an initial hardware setup for BIOS prior to complete OS bootup. What I want to know is if it's hardware engineered to always work this way, if there's another step in this bootup method I am missing, a gap of information I am unaware of, or how this all works from the very first instruction, and the RAM data itself.

  • PC dies when running at 100% CPU

    - by user155631
    I recently wrote some Java code to generate images of the Mandelbrot set (fractal). I made use of the new Fork/Join facility in Java 7 to run separate threads on all four cores (2 real, 2 virtual)simultaneously, using a large number of iterations for greater accuracy. The problem is, the process runs fine for about a minute, and then it's as if someone has pulled the plug and the PC just dies. I thought it must be the CPUs overheating, so I ran Real Temp to monitor the temperature. It's an Intel i3 processor. I can see the temperature creeping up to 70 degrees, and then it seems to level off there and run for about another 30 seconds before dying. According to Real Temp, there's still a gap of 35 degrees between the actual temperature and TJ max. I also tried disabling "CPU TM function" in the BIOS, but the problem still occurs. A colleague suggested that it might be a power supply problem, so I borrowed a more powerful PSU (can't remember what wattage it was, but it's higher than mine which is 500W). The exact same thing still happens though. Is anyone able to suggest what the problem might be, or what I can try next?

  • Using nginx to rewrite urls inside outgoing responses

    - by Kev
    We have a customer with a site running on Apache. Recently the site has been seeing increased load and as a stop gap we want to shift all the static content on the site to a cookieless domains, e.g. http://static.thedomain.com. The application is not well understood. So to give the developers time to amend the code to point their links to the static content server (http://static.thedomain.com) I thought about proxying the site through nginx and rewriting the outgoing responses such that links to /images/... are rewritten as http://static.thedomain.com/images/.... So for example, in the response from Apache to nginx there is a blob of Headers + HTML. In the HTML returned from Apache we have <img> tags that look like: <img src="/images/someimage.png" /> I want to transform this to: <img src="http://static.thedomain.com/images/someimage.png" /> So that the browser upon receiving the HTML page then requests the images directly from the static content server. Is this possible with nginx (or HAProxy)? I have had a cursory glance through the docs but nothing jumped out at me except rewriting inbound urls.

  • VMware guest pauses when the host is idle - how do I keep it running?

    - by EMP
    I'm running VMWare Worstation 7 with Windows 7 x64 as guest, Windows XP x64 as host. Inside the guest I run a long-running console application, which prints out progress messages with timestamps on them. Sometimes I leave it running for several hours while I lock the host OS and don't touch the computer at all. When I come back I find that some time after I left it seems to have paused and automatically resumed: the console app hasn't made much progress and there's a large time gap in its progress messages. There's nothing relevant in the host event log, but in the guest Application event log I can see these messages around the time I left: A request to disable the Desktop Window Manager was made by process (VMware Tools Service) The Desktop Window Manager was unable to start because composition was disabled by a running application And later, around the time I returned, this shows up in the System log: The system time has changed to ?2012?-?01?-?12T06:36:46.921000000Z from ?2012?-?01?-?12T03:18:19.953079000Z. That seems to support my theory that it's VMware doing something and not Windows itself. The question is: how do I stop it doing that? I want my application to continue running. By the way, the power options are set to never sleep in both guest and host.

  • Providing access to a no-www website in an active directory environment

    - by oasisbob
    Our website is hosted externally, off our network. The canonical URL is a is intentionally lacking www, and will 301 redirect any requests containing www to the canonical URL. So far, so good. The problem is providing access to the website from within our LAN. In theory, the answer is simple: add a host record in DNS pointing foobarco.org to the external webhost. (eg foobarco.org -- 203.0.113.7) However, Our active directory domain is the same as our public website (foobarco.org), and AD appears to periodically auto-create host (A) records in the domain root corresponding to our domain controllers. This causes obvious problems: users on the LAN attempting to access the website resolve the domain controllers instead. As a stop-gap measure we're overriding DNS using the hosts file on clients, but this is a quick hack that doesn't scale well. The hosts-file hack hasn't broken anything obvious, so I doubt that this behavior is essential to AD operations, but I haven't found a way to disable it. Is it possible to override this behavior?

  • Ethernet/8P8C crimp contacts bent

    - by Fire Lancer
    (if anyone knows correct terminology please correct). Ive got a (fairly large) number of existing Ethernet cables that over the years many have got damaged connector clips, so got a crimp tool and some new connectors for them. However out of all 4 attempts I have tried, on crimping 2+ of the little copper contacts that bite into the wires have instead just bent to one side, and so gone between the gaps in in the crimp tool... Unless this really is me doing something wrong (what?) I am inclined to blame the hardware, but is this the crimper or the new connectors I got? I tried to take a picture, as you can just about see looking from the left 3rd, 6th, 7th and 8th pins didn't get pushed in, and so don't form a connector. Unfortunately my camera was barely able to focus on it and then this website converted it to a JPEG... Update: Connectors/Cable/Tools: The wires are stranded (looks about 6 and no evidence of being aluminum/not copper), and the pins(?) have 2 little flat spikes lengthways along the cables (I understand to dig into it, while solid core connectors would have like 2 plates designed to go around the core?). Crimper was http://www.amazon.co.uk/gp/product/B0013EXTKK/ref=oh_aui_detailpage_o02_s00?ie=UTF8&psc=1 (seemed to be highly rated, I already had tools for cutting/stripping). Update2: Picture of crimp "prongs" (?) Update3: Side picture of connector Update4: Comparison with old connector. The top (used) connector is one from a few years back (different tool and connectors), the thing that concerns me that it might not be the tool I need to replace is just how thin the pins are on the new one that maybe a tool could legitimately bend some into a gap rather than pushing them in fully? In fact I can move individual pins to the sides significantly with my fingernail, is that normal?

  • How to delete row in TTTableViewController (Three20)

    - by Dmitry
    Hi, The Three20 is great library. It's making the work with tables very easy. But one gap that I noticed - is deletion of rows, with animation. I spent many hours trying to do this, and this is what I'm doing: // get current index patch UITableView* table = [super tableView]; NSIndexPath *indexPath = [table indexPathForSelectedRow]; //delete row in data source TTListDataSource * source = (TTListDataSource *)self.dataSource; [source.items removeObjectAtIndex:indexPath.row]; // delete row from the table, with animation [table deleteRowsAtIndexPaths:[NSArray arrayWithObject:indexPath] withRowAnimation:UITableViewRowAnimationFade]; After this code runs the error appears: [NSCFArray objectAtIndex:]: index (0) beyond bounds (0) I'm using the class inherited from the TTTableViewController. And I doesn't implement the DataSourceDelegate or TableViewDelegate because I'm using the Three20 as much as possible. So, this is how I create datasource: for(NSDictionary *album in (NSArray *)albums){ TTTableRightImageItem *item = [TTTableRightImageItem itemWithText:@"name" imageURL:@"image url" defaultImage:nil imageStyle:TTSTYLE(rounded) URL:@"url of selector where I actually catch the tap on a row"]; [tableItems addObject:item]; } self.dataSource = [TTListDataSource dataSourceWithItems:tableItems]; I read this article (article) but it doesn't help :( So, I know that this is very simple for gurus from this site. Can you just give me advanced sample of how to do this Thanks
