• Thunderbird very slow with Gmail

  - by koskoz

  I'm using the latest version of Thunderbird with 3 Gmail accounts. Every time I launch it it seems it's downloading all my messages again. I've compacted folders (is the action working for the 3 accounts or do I need to do it for each of them?) and deleted the .msc files but nothing change. It leads to a software using a lot of bandwidth and being very slow when using it. It's a pain to write a message or even to view one. All the software is so slow I've never seen that it's almost unusable. I'm using thses addons : Dictionary Google Calendar Lightning My Gmail accounts are configured to imap.

• Why is Cuteflow slow on XAMPP 1.7.1?

  - by gsk

  I have recently installed cuteflow (a PHP based document circulation application) on my machine as I need to customize this software. I have XAMPP 1.7.1 running on a windows xp machine on which this application is deployed. While all my other applications that are running on XAMPP are loading fast, only this application is taking exorbitant amount of time. The same cuteflow application is running very well on my colleagues machines.

• Windows 7 system CPU bogged by windows services, no explanation

  - by Alex

  I'm looking at a laptop for a colleague which is running terribly slow. A quick look showed that the CPU was 100% used by 2-3 SVCHost processes, which off course doesn't tell much since those are just 'cover' processes with services running underneath them. So I fired up process explorer in hopes of finding a shady rogue service which was bogging the system, but to my suprise I found genuine MS Windows processes (or at least damn-good disguised ones) are bogging down the system: dnscache (DNS Client) IKEEXT (IKE and AuthIP IPSec Keyring modules) iphlpsvc (IP Helper) Seen separately, these processes might seem odd to be using a lot of CPU, but taking a step back one can conclude that all three services are quite closely related to networking. I've tried running: netsh int ip reset log.txt which has helped me save bizarre network-related problems in the past, but this didn't help Off course I though about a virus, but both MS Security Essentials as well as malwarebytes (let both run a full scan).

• Basic Weight Questions with HAProxy

  - by Kyle Brandt

  Do weights assigned to servers only effect the balance within that particular backend? When implementing weights for the first time, if I give all the servers in a backend the same number, would that be the same as before when there we no weights? How do I calculate just how much traffic I am shiffting by adjust weights by certain amounts. For example: server web1 10.10.10.10 weight 100 server web2 10.10.10.11 weight 100 server web3 10.10.10.12 weight 90 server web4 10.10.10.13 weight 90

• Do We Still Need Database Design in the Era of Big Data?

  Many big data application implementations seem to begin with an existing data warehouse, one or more new high-volume data streams, and some specialized hardware and software. The data storage issue is often accommodated by installing a proprietary hardware appliance that can store huge amounts of data while providing extremely fast data access. In these cases, do we really need to worry about database design?

• Need reasonably priced router with QoS support [closed]

  - by ULTRA_POROV

  I dont need wireless. I am expecting very heavy traffic, with possibly thousands of tcp connections open at one time. This would require that the router has good hardware. I also need to limit the different services i will provide. Lets say i need to guarantee 60% of all the bandwidth to HTTP, 10% FTP, and 10% for Mail... So the router software must have flexible QoS options as well. I don't know which one to chooose, because this information is usually not given on the router specs.

• How to remove the pause during JBoss 5.1.0 GA boot between ProfileServiceBootstrap and AnnotationCreator?

  - by rrc7cz

  I've managed to strip down my JBoss profile enough that it boots in 1.5 minutes. I started with the web profile and started pulling out stuff I didn't need. The bulk of my boot time can be seen here: ... 15:21:51,890 INFO [ProfileServiceBootstrap] Loading profile: ProfileKey@86d597[domain=default, server=default, name=np] 15:22:55,406 WARN [AnnotationCreator] No ClassLoader provided, using TCCL: org.jboss.managed.api.annotation.ManagementComponent 15:22:55,578 WARN [AnnotationCreator] No ClassLoader provided, using TCCL: org.jboss.managed.api.annotation.ManagementComponent ... Does anyone have any idea what JBoss is doing here for 1 minute? If so, is there any way to speed it up or skip it entirely? This is for developer instances, so boot time is quite important.

• Settings object with singleton pattern

  - by axis

  I need to build an object that will have only one instance because this Object is dedicated to the storage of vital settings for my application and I would like to avoid a misuse of this type or a conflict at run-time. The most popular solution for this, according to the internet, is the Singleton pattern. But I would like to know about other ideas or solutions for this; also I would like to know if other solutions can be much more easy to grasp for an user of this hypothetical library. Thanks.

• I need to create an employee schedule/appointments program, but I don't know how to set it up

  - by robz228

  I work for a gym. I am the programmer, its just me, nobody else! Gets really frustrating when there's nobody to bounce conceptual ideas off of. I'm getting rid of our archaic paper binder systems for tracking appointments and what not. I've made a lot of things successfully already, now I'm trying to tackle the personal training department. What I want: Trainer information and work schedule Appointment booking that can be done by time slot with all available trainers for that time, or by trainer with all available hours for that trainer What I've tried so far: I started with an 'appointments' database, a 'trainers' database, and a 'schedules' database. This became so complicated trying to fit the schedule in that I scrapped it. Does anyone know know the best way to structure the tables for this and how to sort of make them communicate correctly? I don't need specific code, I just need help understand how to make this thing!

• Very high Magento/Apache memory usage even without visitors (are we fooled by our hosting company?)

  - by MrDobalina

  I am no server guy and we have issues with our speed so I come here asking for advise. We have a VPS with 2 cores and 2gb of RAM at a Magento specialized hosting company. Over the course of the last weeks our site speed has gotten worse, even though our store is new, has less than 1000 SKUs and not even 100 visitos a day. At magespeedtest.com we only get 1.87 trans/sec @ 2.11 secs each with a mere 5 concurrent users. Our magento log files are clean, we have no huge database tables or anything like that. When we take a look at our server real time stats, we see that the memory usage jumped up from about 34% to 71% and now 82% in just a few days in idle, with no visitors on the site. Our hosting company said that we do not need to worry about that as it`s maybe related to mysql which creates buffers (which are maybe not even actually being used) and what is important is CPU and swap - stats are ok here. They also said that the low benchmark scores are caused by bad extensions or template modifications on our side. We are not sure if we can trust that statement as we only have 4 plugins installed (all from aheadworks and amasty which are known to be one of the best magento extension developers). Our template modifications are purely html and css, no modifications to the php code. Our pagespeed is ranked with 93/100 in firebug and Magento is properly configured, so the problem really just gets obvious when there are a handful of users on the site at the same time. Can anyone confirm our hosting`s statement about memory usage and where can I start looking for a solution?

• Do control groups improve system performances?

  - by qdii

  According to this website, enabling cgroups in the kernel can boost performances by sharing resources in a better way. In particular, the conclusion states that:  Nevertheless, with a little trial and error, cgroups can help you improve the efficiency of your systems’ resource usage and avoid downtime due to overusage of a single service. Kernel seeds, however, recommend to deactivate them altogether. They say: Consider these [kernel] settings poison. They remain nothing but system slow-downs. They are all off by default [in the proposed kernel config file]. Who should I trust?

• How do I prevent users from entering a blank value in an Excel sheet?

  - by Tola Odejayi

  I want to restrict users to entering either just 0 or 1 in an Excel 2007 sheet. I use the Data Data Validation dialog to do this, but I'm finding that it doesn't stop them from entering blanks. What I would like is for there to be a prompt when they enter blanks, just like the one that appears when they enter any other non-blank data that is not 0 or 1. I plan to fill the sheet with 0s before applying the validation, so there should not be a problem with erroneous data. Also, I'm open to using VBA to fix this problem.

• Some Portions of Computer Running Slow (Specifically Graphics)

  - by Mike Gates

  I noticed that a few things are running slow today on my Windows 7 laptop. Specifically, they are: Opening and closing windows takes several seconds for the animation to complete. Windows media player opens fine, but the movies are very laggy MMORPG's, such as RuneScape, are extremely laggy When waking my computer from sleep mode, after entering my password, my desktop takes about 3 seconds to fade in Other than those, everything runs at a normal speed. Things I've done that maybe contributed to this problem: Changed the graphics processor (by plugging in/unplugging the charger) [however, no matter how I change the graphics, I'm still getting this lagginess] Installed AdBlock, a Firefox addon [I recently removed it, and I'm still experiencing this problem] Went into Advanced System Settings, Clicked Settings, and unchecked a few visual things (such as the animation for opening and closing windows) [sure, this got rid of the opening/closing windows lag, but I like that little animation - plus that leaves all the other lag problems I'm experiencing] So, does anyone have any ideas/fixes? If so, please respond. Thank you. Some Other Information: I'm on a HP Pavillion dv7 laptop, 4285 Entertainment PC, with: intel CORE i5 inside, ATI Mobility Radeon Premium Graphics, Microsoft DirectX11 Opening and closing of windows: Defined as opening a program (i.e. Firefox) or closing it by hitting the X in the upper-right hand corner. Lately, the animation for opening and closing windows (which is simply either growing from the icon from the taskbar to fill the screen, or shrinking from the screen down towards the icon on the toolbar.) This problem also occurs for minimizing/maximizing windows. Very laggy movies: defined as .avi movie files saved to My Documents which skips several frames per second and seemingly slows down the movie as a whole Extremely laggy games: I tried RuneScape today, and movement in the game was at least 10x slower than it ever has been, even when playing on the lowest detail/graphics Desktop taking 3 seconds to fade in after sleep: in this scenario, I had no other programs running visibly. The computer generally fades to black from the password screen to the desktop in about 1 second, normally. However, it is now taking 3 or more seconds.

• retrieve data based on date range using mysql ,php [on hold]

• Managing different utility classes between engine and libraries

  - by hayer

  I'm currently in updating some engine code (which does not work, so it is more like creating a engine). I've decided to swap over to SFML (instead of my own crappy renderer, window manager, and audio), Box2D (since I need physics, but have none), and some small utilities I've built myself. The problem is that each of the project mentioned over use different types for things like Vector2, etc. So to the question: is it a good idea to replace Box2D and SFML vectors with my own vector class (which is one of my better implementations)? My idea then was to have a separate .lib with all my classes that should be shared between all the projects in the solution.

• How to know which protocol is used in data transfer and inspect that data?

  - by user37880

  I've a .net application for windows. This application transfers a lot of data to and from a particular server on a fix port no 8888. I tried 'Tcpview' but couldn't figure out anything useful. I only figured that it uses 'tcp' connection. Is there a way to know which protocol is used for data transfer (I think port no 8888 is not specific port so not helpful)? How exactly my machine makes connection to this server? Is it telnet/http etc or what? How can I inspect the actual data which is being transferred? If data is encrypted, is it possible to know encryption method on client side (without reverse engineering)? Thanks.

• How to monitor a Windows process' working set greater than 4GB?

  - by Shoeless

  Apparently the .NET framework has a bug that prevents working set values above 2GB from accurately being determined. Between 2 and 4GB one can apply some xor-ing calculation to obtain the value, but there's no means of obtaining working set values greater than 4GB (using .Net or WMI) What method can be used - preferably from a PowerShell script - to obtain an accurate measurement of a process' working set when the working set is greater than 4GB? (some side details can be found in this StackOverflow question)

• Make a server ( other than the router ) to be the default gateway for a subnet

  - by powerguy123

  I am trying to make a server ( lets call it server_A) which is different from the router to be the gateway for a subnet. Why do I want this ? I want to host a loadbalancer on server_A using LVS-NAT, and I dont want to implement a V-Lan or IP-IP tunneling. I have modified the routing tables of the remaining servers on the subnet to use server_A as the gateway. I have set server_A to not send ICMP reroute packets. But most traffic from servers in that subnet to outside clients are still being sent through the original gateway, bypassing server_A. Is there any other configuration I need to set in order to achieve my goal ?

• Best way to say "sync all system clocks to this server, when and ONLY when I say so?" Mixed setup of Windows+Linux servers.

  - by twblamer

  Title pretty much explains it. Let's say there's 100 servers, various versions of Windows and Linux, and one Windows server is the "master clock." I did look at this question: How do I synchronize clocks between Linux and Windows? This hints that ntp can do what I want if I run "ntpd -q" on a client (?). If I install ntp I also need to guarantee that it will only sync the times when I force it to. Even better if I have a log that tells me every time a sync was performed. I'm doing benchmark runs and I need to be able to say something like this: "Clocks were synced on all the benchmark systems at 09:42:01am on the master. A benchmark run was then initiated and allowed to run for six hours. None of the system clocks were altered during this time interval." I understand there is subsequent clock drift, but for now that's the way we're doing things and I'm doing it with a manual process. I'd rather at least automate the one-time sync.

• Setting thresholds via smartd.conf

  - by JPerkSter

  Hello! We currently use smartd to monitor SMART health on our disks. I would like to set the 'thresholds' that smartd uses to report. For example: 197 Current_Pending_Sector 0x0012 100 100 000 Old_age Always - 9 198 Offline_Uncorrectable 0x0010 100 100 000 Old_age Offline - 9 I would like to be able to set a threshold for these two attributes to only report if they are above 10. I haven't been able to find a way to set this via smartd.conf, and I'm also not looking to actually shutdown the daemon. Has anyone ever tried this, or know how I might be able to accomplish this better then throwing a script into cron.hourly?
