Hello I have a problem on ubuntu server with group and owner permissions of a directory I have 3 users mat,Brandon,kylian I have the folders /servers/mmtp /servers/Brandon Now I set the home directory from mat to /servers/mmtp and the home directory from Brandon to /servers/Brandon I also made the groups mmtp and Brandon I have set the folder /servers/mmtp to owner kylian and group mmtp same for the /servers/Brandon owner is kylian and group is Brandon wen ever I set the permissions from these 2 directory's to 0755 both users can access edit and delete all files in each directory I want it so kylian can access everything and mat can access /servers/mmtp and Brandon /servers/Brandon but not each others folder setting permissions 0755 will allow them to both edit the directory even though the groups and owner are correctly set

Hi, a few weeks ago i was deleting big amout of empty folders made by a different user on a server. But suddenly the deleting stopped halfway, because i did not have access to the folders. So i aborted the deletion and checked the ownership. I was listed there as owner. Can anyone explain this to me?

Here's my review of the Lenovo X250. Be warned, it's fairly long. https://docs.google.com/document/d/1HPt4AQBLEhy64PEYWVdZjonO8Hc0ALdGdlVzTA3nNRU/edit?usp=sharing I would really appreciate feedback. What's good? What's bad? What should I add in the future? SEE THE GOOGLE DOC FOR THE PROPERLY FORMATTED REVIEW w/ PICTURES and BENCHMARK IMAGES ilikemacandpc’s Lenovo Thinkpad X250 Review September 2015 Image from lenovo.com Introduction and Pertinent Notes Lenovo’s Broadwell based Thinkpads are here, and with the imminent launch of Skylake, I thought it may be a good idea to take a look at the X250, the smaller sibling of the T450s, to give us an idea of how the hypothetical X260 and T460s will go. Note 1: This is a personal computer that I bought for college. Let’s hope it lasts 4 years. Note 2: Parts of this review were originally intended to be part of a first impressions post, but the details quickly spiraled out of control. My apologies if it sounds a bit disjointed at times. tl;dr: The X250 is really good, and Skylake will only make it better. Wait for the X260. Specifications of My Unit Processor 12.5” IPS 1080p 400-nit display (non-touch) Display Intel Core i5 5200U with HD Graphics 5500 RAM Storage 8GB of RAM - DDR3L 1600 - Self Installed - Came with 4GB of RAM from the factory 250GB Samsung 850 Evo - Self Installed - Came with 500GB HDD from the factory Weight Battery A bit under 3.5lbs 3 Cell + 6 Cell Battery (~95 Wh) Size (WxDxH) 12.03" x 8.21" x 0.8" or 305.6 x 209 x 20 mm Software Clean Install of Windows 10 Price Approx 1100 USD including education discount and ALL upgrades both factory and aftermarket Hardware Analysis The Intel Core i5 5200U is a good processor, but Lenovo should have equipped a 5300U by default. As Linus pointed out in his review of the X1 Carbon, both the 5200U and the 5300U have the same retail customer price (RCP) and the 5300U has business features like vPro. Lenovo is shortchanging customers by charging another 100 USD for the upgrade to the 5300U. Shame on them. Prices from Intel ARK as of Sept. 2015 At the moment, 8GB of memory seems to be enough for me. If an upgrade is necessary, 16GB soDIMMs are available, so this laptop could be outfitted with double the current amount of RAM, which is insane considering its footprint. However, the main drawback is that the RAM is in single channel, causing a 15-25 percent dip compared to dual channel HD Graphics 5500. It’s roughly as fast as the last gen HD 4400 on Haswell processors with dual channel memory. Not terrible, but certainly not great. Then again, a gaming rig, this is not. SSD upgrades are quite expensive. I would like to see a PCIe M.2 option, so that we could put in drives like the Samsung SM951 series to have significantly better speeds. Getting touch capabilities on the monitor is really expensive, so the 1080p non-touch display is at the sweet spot. Considering how much more keyboard and mouse friendly Windows 10 is than Windows 8/8.1, the lack of a touch screen is not an issue at all. The Display Starting off with the display, it’s excellent. With a decently high quality IPS panel, viewing angles are great. I also don’t notice any color banding even with large gradients. There is the tiniest bit of backlight bleed at the lower right hand corner, but I only notice it when the screen is entirely pitch black. When watching a dark video in fullscreen, the bleeding is not noticeable. Only on a completely black frame is it noticeable. I’ll take this amount of backlight bleed over a TN panel every day of the week. Low brightness is rather low, and maximum brightness is headache-inducingly bright. You should be able to use this display outside due to the obscene amount of light coming through the panel and due to the anti-glare coating. My anecdotal experience supports this claim. Chassis, Ports, and Build Quality It’s a mixed bag, though mostly positive. It comes down to the battle of plastic versus aluminum and the pros and cons both materials afford. Lenovo claims to have a metal roll cage inside of the X250 to improve durability, and that the plastic is carbon-fiber infused, but for all intents and purposes, this is regular plastic, albeit high quality. Lenovo is sticking to the black rectangle, which is good. Instead of changing up the perception of what a laptop should be, Lenovo keeps the Thinkpad identity physically the same. As a result, this is not a particularly thin laptop, or curved, or majestic in any unique way. This is a business laptop, and it fulfills the job well. There is one advantage that this somewhat chunky build affords; in terms of ports, the X250 is loaded compared to the competition. Category Ports Commentary Inputs 2x USB 3.0 - one with sleep and charge Ethernet (YELL YEAH!) SD Card SIM Card Lenovo should have added a 3rd USB port for power like on some of its other laptops. Display Outputs VGA (in 2015 lol) mini DisplayPort Two connections is fine. mDP is preferred over HDMI Other Power Input Kensington Lock Thinkpad Docking Port Docking Accessories are quite expensive. Yet again, Lenovo displays a feature that makes it stand out compared to all of the competition. Not one other manufacturer comes close. In terms of weight, this is freaking magically light. I often get worried that I didn’t put my laptop in my backpack because my bag feels so darn light. Especially without the additional six cell battery, the laptop reaches a stupendously light weight. A single decently sized hardcover book is heavier than this laptop. However, being able to open this laptop up is a godsend. The end user (or I) could save a ton of money by buying an SSD and RAM upgrade outside of the Lenovo laptop configurator. The Trackpad and Keyboard The Trackpad not made from glass. Or at least it doesn’t feel like it’s made of glass. This year, Lenovo corrected the cardinal wrong from the Xx40 series - the lack of dedicated buttons for the trackpoint. The problem is that if your hands are even the slightest bit sweaty or oily, the trackpad gets very hard to use. There is a significant amount of friction between the hand and the trackpad, making it very uncomfortable to use. However, I do have to give high points to the Trackpoint (nub). It works well and is rather precise. I think that I’ll try and use it for a while because I just don’t like the trackpad. On the other hand, the keyboard is almost flawless. What needs to be mentioned is the huge amount of key travel on the X250, a major advantage over its competitors. Lenovo achieves this via a slightly chunky build and surprisingly thin keycaps. I hope it will not affect durability. The only thing I would change about the keyboard would be to add more granular control of the backlight. It only has 3 levels: off, bright, and super freaking bright. When it’s pitch black in the morning in my room and I’m trying to use the laptop without waking up my roommate, the keyboard backlight almost feels brighter than the screen itself at minimum brightness. This is one detail that Apple got right - giving many levels of brightness for their keyboards. Performance and Thermal Throttling It’s what you’ve all been waiting for: the benchmarks. The X250 performs as you would expect from a laptop of such specs. No thermal throttling was observed even after several runs of Cinebench R15 which is promising. Geekbench 32-bit and HTML5 Test : Cinebench R15 and Crystal Disk Mark: However, there is a big problem; This laptop cannot smoothly stream 4K video in Chrome, Firefox, IE (shudder), and Vivaldi. BUT, in Microsoft Edge, 4K streaming works beautifully. WTF Google?! YouTube doesn’t work well on your own browser? The higher quality playback at lower CPU usage is the only reason I (or anyone else for that matter) would use Edge. It is a shame that other browsers with more power user features lack the performance of Microsoft’s own browser. Even with the improvements in Chrome 45, Microsoft has the edge (pun intended). During a stress test in AIDA64 of CPU Integer performance alone, the laptop held steady at around 65 degrees Celsius in a 21.1 degrees Celsius room. Though the fans did spin up a bit, I would rather the notebook be a bit lounder than thermally throttle. Max all core turbo seems to be just shy of 2.5 GHz, in line with Intel’s specifications. Generally, under light to moderate load, the fans are unnoticeable. The Elephant in the Room - Windows 10 Scaling Ahh Microsoft. You make excellent products (most of the time) and you had a chance with Windows 10 to fix some serious errors that you had. Alas no. Display scaling, tested at 125 percent, is still bad, even on a laptop that doesn’t have a super high DPI display. Most installers I use seem to have scaling issues, showing blurry text. Normally, however, the application launches fine and crispy. However, I do HAVE to call out Skype for not only the installer being blurry, but the application itself. And it is a Microsoft owned application. Both the Google Chrome and Steam Installers are noticeably blurry. This is unacceptable. Also, Steam is blurry! That’s unacceptable to me. Maybe I have some settings configured incorrectly, but Steam, of all applications, should support high DPI displays properly. As of this moment, I’ve set the display to 100% scaling just to avoid these issues. Thankfully, my vision is good enough that seeing text isn’t hard, and the extra screen real estate is appreciated. At times though, small text can be tough to read. I’ve had to set the zoom in Chrome to 110% because below that is just annoying to read. Battery Life and an Important Note about Charging I have had some issues with the batteries not charging up to 100%. They’ll go to 97 or 99%. However, if I partially drain them, say to 50%, and then recharge them, they will go up to 100% full. Odd. Either way, the battery life on this laptop is tremendous and easily best-in-class. The X250 lasted hours under AIDA64 CPU stress testing. There is likely no way I’ll ever drain the entire battery in one day. At the end of a long day, the battery is at just under 60 percent full. Only long periods of gaming and other CPU/GPU intensive activities will kill this laptop. However, the target audience for this laptop likely will not be doing those things, so battery life shall remain excellent in all normal scenarios. Miscellaneous Thoughts Using the X250 over the past couple of weeks has really made me want to to see the proliferation of Thunderbolt. Every day, when I get back from class, I plug in 5 cables into my laptop (Power, mDP, USB, Ethernet, Audio). It’s hugely annoying. Plugging in just one cable every time would be a godsend. The fingerprint reader works 80 percent of the time the first time, 98 percent of the time the 2nd time, and 2 percent of the time it doesn’t work at all. It simply does not turn on at the lock screen which is strange. And despite my privacy concerns with Windows 10, the convenience of the fingerprint scanner cannot be overstated. Random Oddities By default, the auto-brightness is extremely aggressive and changes brightness even in constant light. Disabling adaptive brightness in the Intel HD graphics control center fixed the problem. Weird. The traditional inversion of the Fn and Ctrl key on Thinkpads continues. Key remapping software can fix that easily. Looking at the display housing, the panel seems to be the slightest bit crooked. Thankfully, no display is behind the bezel, but the gap is larger on the top than on the bottom. It does NOT affect the usability of the laptop, but the lack of fit and finish irks me. Windows isn’t great at calculating remaining battery time. It can say that I have 5 hours left on a fully charged battery, which is simply not true. Windows 10 still isn’t perfect. In one year, with a series of stability and glitch fixing updates, the OS will be much better. This is likely why Lenovo still only offers Windows 8.1 or Windows 7 from the factory. Conclusions This is a really good laptop. I really do wish I could have waited for Skylake to get the GPU gains, but I’m fine with this. If I wanted to game, a real desktop would do a significantly better job anyway. Though I could have chosen between this, the Dell XPS 13, the HP Spectre X360, and the MBPr 13”, I chose this due to being able to take this laptop apart and due to the insane lightness and price of this laptop. Using the educational discount available, this laptop rapidly becomes much cheaper than any of the other aforementioned, and it has a significantly better selection of ports. In the end, however, with the launch of the X260 almost here, any consumer should wait and see the benefits Lenovo will bring. Skylake will bring better battery life, more processing power, and better graphics, hopefully solving most of the issues with the X250. There are minor nitpicks, but no laptop is perfect, especially considering the price.

Hi all! One click away from ordering this card. I'd like to ask this community (specifically, owners or previous owners of this card) if my findings are indeed true. Is it true this card suffer the least from coil whine? I have done in-dept research, going over critic reviews, user reviews, youtube, and all sort of stuff. I have concluded the card that people reported the least coil whine is the MSI Gaming 6G variant (The most reported being Gigabyte G1). Can I have some final thoughts on my findings? Whether there is other cards with even lower chance of coil whine or my finding was wrong and the Gaming 6G has as much coil whine as other cards. I'll be switching from an Asus Strix. Despite it's insanely good cooling for a reasonable price (50C on load when fan 100% dafuq), the coil whine is a huge turn off. I am aware the MSI Gaming 6G cooler is not as good as the Strix, but what's the point of a more quiet fan when the coil whine is louder than the fans on load? Thanks for reading!

Hello everyone! I could not find something like this, so I decided to make one myself, hope this is okay So as the title states, this is the Unofficial Pebble Owner's Thread! For people who own pebbles and want to talk about apps for it and what they have on it. I'll start I have the Original Red Pebble with these apps and watch faces installed: Watch faces: Glow Modern Time Apps: Pebblets PebbleApps NotificationCenter 2048 Pop Quiz Glance Communicator Pebble Dialler GryoMaze Ledge Climber This are some of the ones I have installed now, do have alot in the locker which I won't state, but you could state it yourself if you want! Just though it would be fun for people to show what configs they use, enjoy!

So I'm looking for somebody that could measure THE INSIDE of their Fractal Design Define R4 for me. The request may sound weird, but I want to have leds like dis Thanks in advance to whoever makes time to measure their R4 for me, and I'd also like people to tell me ways to do this LED thing without handicapping the front cover. Any tips and tricks on leds? Post your LED builds and write what you did.

Hi guys, So I am managing a Windows 2008 Server (not R2). On it, I am sharing a folder. Under advanced sharing, the permissions are given to a specific group on the Domain Controller. On the Domain Controller, a user is in this group. However, this user does not have permission to view or edit this share. Even though they should. The only way they can connect to the share and view/edit it, is if the group Authenticated Users is added to the permissions of the Share. This, however, gives all users access to the share. For security reasons, this is bad. Obviously. I tried adding the user directly to the permissions list, which didn't allow them to view/edit the share either. I tried that because I have a similar (but not the same issue) where a different user is a part of a different group. And all users in that group have access to the share but except for that user. And the only way to give that user permissions is by directly adding them to the permissions list. Those are two different problems, but their root is the same. Sharing permissions isn't working right between the Shares and the Domain Controller. Any help is appreciated. Thanks, Vitalius
