    posted a message on What operating system do you prefer?

    Not exactly like I have a favorite, though at home and stuff ended up getting frustrated with windows recently and jumped ship to see how long i could live without windows at home. I really don't game anymore and what I do works fine. At work i run Win10 with cygwin for things like ssh, using cat to write to disks, and serial console access.

    Quote from Dankrushen»

    Yeah, I hope Linux does actually take the spotlight and starts getting to real deal development work. I find windows slow, and it runs off its own kernel, which isn't always a good thing. With Linux, anyone can improve the kernel, as it's fully open source. It's a pretty stable build off of Unix, so it's had plenty of time for the community to make it into what they need. I wish Windows would die faster though. The more I use it, the more I hate it. I can also see Windows users starting to get annoyed at recent changes to the operating system, so maybe the community will decide to stop using Windows. And it's sorta funny. Most things are developed entirely on Linux, then suddenly compiled for Windows in the very end, for example, Google. Their entire company headquarters run off Linux, yet there's barely any support for good ol' Linux.


    You realize the Linux kernel is very well funded, there is not a drought in development in it. There is somehow an Idea that Linux is not used or some underdog operating system. In reality a distro of Linux is everywhere, the ESXI kernel that is used by VMware is a Linux base. Where I work our whole networking infrastructure runs on Linux, Dells N series switches use the Force10 OS and uses the Linux kernel. Most major services use some form of Linux on their servers. Android is a Linux base, tons of embedded applications run Linux.

    There is not a project that is really trying to push into the market that Windows controls. Linux is not some underdog desktop OS, Linux is not losing it already won just not in the desktop market. Where I work there exists not a single Linux desktop OS installed then on my laptop I use to quickly console into networking equipment if SSH goes down. Yet close to 30-40% of our servers are Linux based, we are looking at swapping to canvas as our LMS that might cause us to break 50%. Yet still don't think we would consider running Ubuntu as some desktop windows replacement. A lot of our educational software even supports the Ubuntu LTS officially. Even if Microsoft Office had a full fledged Linux release we would still not switch. There are just things that the Linux world does not have.

    posted a message on Ubuntu, Is it wroth reinstalling?

    With Linux distros people refer to "lightweight" distro as having better performance this is really truly different then actual performance as Xiae pointed out. It really depends on what GPU for game performance, I am not sure what GPU and what drivers are used in that above example. For Intel GPUs performance is pretty much identical between Windows and Linux as they use the same code base for Windows and Linux drivers for the most part. AMD generally has the better drivers on Linux then Nvidia depending on what card and driver. With Linux I typically just talk about open source drivers, with proprietary Nvidia typically takes the lead but my experience is both AMD and Nvidia proprietary drivers are trash on Linux with tones of strange issues.


    The driver situation is improving, but so far nothing really to compete with Windows in terms of graphics driver quality. So if you are after it for a performance perspective then there is really no points but if you are wanting to learn or just tinker with Linux then go ahead I guess.

    posted a message on What is your favourite Desktop Environment (For Linux/BSD users)

    For when I do Unity is about the only one I like, Gnome3 is not terrible either. Now that I manage Linux servers as my job I actually use windows more often now as the only time I interact with any Linux distro is via SSH.

    posted a message on Campus upgrade with Dell Networking

    Not sure, how many people here are all that interested in networking, but I would like to see more discussion threads here again. In addition, I figure here there will not be the gut reaction of hatred towards Dell's Networking products.


    I work at a small college, we have been trying to budget out to upgrade our older network infrastructure. The bulk of it is Cisco 2960s, 3550, and 3750s as our intervlan routing and distribution layer of our network. Our 3550s are tagged with a manufacture date of 2005 and most of our 2960s are not that much younger.


    Our budget to overhaul the network is not as big as I would like so this has pushed us at looking for alternatives to Cisco. We brought this up with our vendor that sells us the bulk of our equipment and they said Dell networking has really improved and the Force10 OS based switches.

    We managed to get a free Dell N1548P and our experience has been fantastic. Force10 OS commands are identical IOS commands for just about everything.


    Something we did not even plan on but Dells power consumption (Not counting POE in these numbers) is beyond fantastic. Our current Cisco switches consume about 70-100W depending on load. Our new Dell is 8W on average with 21W during load. Even Cisco newer offerings for access layer switches the 2960-X series the 0% load consumption is still around 30W. Upgrading our networking equipment is going to cut our power consumption by about 10,512 kWh/year. The lack of support for shutdown on port-security violation is really the only feature we are missing, and being able to set MTU on a per port basis.


    With that going well we decided to take our vendor up on an offer to package our new server and san with two Dell N4000 switches. Most of the problems I found people talking about either were minor or have been patched. The only major issue we found is when using non-Dell certified third party SFP 1Gbps modules with auto negotiation to a Cisco switch would cause the operating system on the switch to hang. Latency testing showed more consistent performance pings are down below the 1ms on average. When before it was very possible to see pings be about 8ms average with spikes into the 20-50ms range.


    Overall happy so far with our experimentation into Dell Networking, depending on when we get the numbers I may update this thread once we get the costs to upgrade our network with Dell vs Cisco equipment. Our quick math shows we might be saving 10k dollars but our vendors sometimes manage to get equipment a lot cheaper. We also don't have to pay for IOS licensing with Dell.

    posted a message on How to increase FTP transfer speed?/Or LAN speed in general

    Is the server connected via USB 2.0, older USB standards are not full duplex this can add to the latency even on a local connection due to the effect I talked about below. I would recommend just implementing a NFS and map it as a drive in windows this should work faster.


    You can also implement Ethernet Jumbo Frames this can have a positive effect on TCP throughput.


    This is what I typed up about internet servers and TCP though this might still apply if you are using a USB2.0 and even on a LAN the latency can artificially cap the transfer speed of FTP due to the nature of working on TCP.


    This comes down to an inherent “flaw” in FTP and anything that uses TCP. Using TCP means the computers wait for the ACK that the packet got there before sending the next. This is great for reliability but this also means that higher latency connections ruin FTP throughput due it the underlying protocol of TCP.


    The other part of this is TCP can scale the amount of data it is moving and if the network is reliable over time it will increase the window size this meaning it will transmit more data before sending an ACK. However, this is done per TCP connection so smaller files; do not see the full benefit of adjusting the window size. Therefore, this is not a problem with FTP but rather TCP working as intended.


    Not exactly sure what the problem is this information is typically whats wrong with TCP throughput. I really just recommend implementing NFS


    Edit: Trying to think of reason why your server would be connected via USB 2.0. This is not running on a Rasberry Pi is it? If you are using an external disk with he PI it is sharing the USB bandwidth with the USB port the network port is using.

    posted a message on Huawei
    Quote from _Xiae»

    Honestly, while the Nexus 6 is by no means a bad phone, I would have probably gone with the 6P/5X over the 6 simply due to the fact it's too big. It's just too big of a phone to use one handed, in a sense it's more a small tablet than a smart phone.

    I originally when I saw phones of that size I thought kinda the same. Then I was thinking of how I use my phone, reading support tickets at work, looking up documentation while in networking closets, texting and phone calls. Thought I would give a larger phone a try and now really happy, I typically use my phones two handed anyway so works for me. Plus not like even a smaller phone was going to fit in my pockets.

    Bigger phones aren't for everyone, but I think for some people they work well.

    I would doubt Google would select a bad manufacturer for their nexus line. They are a phone company just one that is not particularly popular in the USA smartphone market. Read that they are the number 1 manufacturer of smartphones in China.


    Also toss in a recommendation for the phone that I will own in 3 days the Moto X Pure(or Style) was 400$. Then bought a 50$ 128GB SD card from Newegg and suddenly phone with 144GB of storage.

    posted a message on Windows 10 For or against?

    We have been deploying it to our test groups at work and all have responded pretty positively. The multi monitor support is the major reason of support. That and some of the weird group policy issues seem to have resolved them selves though this could just be a fresh install and not that Microsoft patched group policy some.


    MDT deployments for it doing an upgrade is still broken after they released a patch for MDT 2013u1 that was supposed to fix a lot of the deployment issues. The new lighttouch that it ships with deploys everything faster not sure if it does some compressing or something with the server or just better usage of processing power.


    Your data is mined all over the place and tons of software phones home to give data developers want to know how people are using their software on what type of hardware.


    The RSAT tools for it seem unstable compared to Win8.1s so a pretty big annoyance there. Going to do a test desktop pool of it in VMware horizon see how it handles it.


    So ya I do like it a lot on an Enterprise level there seems to have been a lot of bug fixes(compared to 7 at least, though a lot of our Windows 8 machines did not have the issues that a lot of the Win7 machines had) I love the new multi monitor features it has been a big pet peeve I have had with windows for a lot time.

    posted a message on Is Kingdom Hearts 1 & 1.5 sountrack the same?

    Kingdom Hearts 1 tracks are basically like a MIDI format where Kingdom Hearts 1.5 they had the hardware and monetary budget to actually record the music.


    They are different and from a Nostalgia standpoint I like KH1 better but I think if you erased my memory and played both side by side I would prefer the 1.5 tracks.

    posted a message on My first impressions of Windows 10 (So far) - Share yours!

    As a test decided to see how well Win10 handles MDT/WDS deployment and the answer is good and bad. The new Litetouch/Winpe version seems to have done something either it compresses more over the network but all my imaging has had a solid speed performance improvement. However running the upgrade through MDT seems to be hit and miss and deploying works some of the time but runs into random errors. Have not done any captures yet so will have to play and see if that works out.


    We pushed Win10 to several instructors in the Information Systems department and in the IT Dept to see if the bulk of programs work alright and to find any issues that break some registry stuff we push via GPO or just other nonsense.

    posted a message on My first impressions of Windows 10 (So far) - Share yours!

    Microsoft forcing updates is good, seen to many family members who defer updates forever. Really Microsoft needs to get better at not needing a restart to update and not needing batch after batch of updates requiring restart and more updates. Where I can get a simple apt-get upgrade once and be done on my Debian servers. A solution already exists for enterprise situations where MS can assume someone running WSUS has good reason to defer updates. On a home level ya this is kinda annoying, but most people just don't care enough to make sure there computer is not part of a bot net and that can damage a public resource the Internet. So really just Microsoft making sure users of their products are not contributing to a problem with botnets and other exploits.

    I use my computer for things other than programming, server administration, and casual use, ergo I can't feasibly use Linux for my day-to-day tasks. "Never going to be usable" it is then, I suppose.


    Notepad++ also does this.


    Was not exactly sure why you felt it was unusable but some people talk as if just one year someone is going to make it just like Windows and then everyone will jump ship. One of the best IDE only exists in full on windows so even most people who program tend to gravitate towards windows it seems there is really nothing magical about programming on Linux not quite sure how it got the stereotype of programmers OS.


    Linux is not a competing product from a competing company trying to best Microsoft at making a Windows operating system. It is really only some end users the developers behind the OS feel they have won and are accomplishing their goals.

    posted a message on 8-bit resolution chromium on ubuntu 12.04lts

    As far as I can guess this is just botched text rendering, can't exactly know for sure but you are running a dated Ubuntu release even if it is still supported I would recommend jumping to 14.04 LTS if you would like to stay on the "stable" editions. Not really sure how Chromium handles text rendering but this could be an issue of the application being built using newer QT features that the toolkit version in Ubuntu 12.04 does not support. You could also see if there is updates for your OS maybe a patch for the toolkit version or you can use a PPA/Repository to get some newer versions I believe chromium still runs QT.


    But really with the amount of improvements to Unity between 12.04 and 14.04 and 15.04 I would really recommend updating to a newer version.
