Advantages of BSDs The *BSD family of systems has (IMHO) a few key advantages over Linux, particularly for a server O/S. Simplicity and Control: None of the *BSD distributions have the imperative to add features that the Linux distributors exhibit. Thus, the default install of most BSD derived systems is relatively simple. Stability: Partially driven by ...
32-bit can be slightly faster in certain use cases -- the smaller addresses means sightly more compact code, which means greater cache efficiency. In the benchmarks I've seen, that efficiency tends to be be overshadowed by 64-bit's greater computational efficiency in heavy-computation environments. But 32-bit does in fact occasionally win on some ...
The only reason I can think of to keep a 32-bit desktop operating system is if you use old 16 bit (e.g. DOS) programs and you do not have the windows version which supports Windows Virtual PC. (And even then I would install a 64 bit OS and use something like DOSbox). Edit: There actually is another reason: Hardware which fails to cope with more than 4GB ...
The current one just works!
Whichever OS you can support the best - seriously, for relatively basic stuff as you've described they can all do a good enough job so it comes down to how quickly you can set it up, how often it stays up and running and how quickly you can fix it when it breaks - so in my mind the best is the one that you yourself can deal with best in these situations.
I am yet, in 15 years in the industry, to start a new consulting role at a company to find that they have a "good" infrastructure. That's usually the reason why I'm called in, to put them right. The usual cause of this mess is non-technical decision makers making technical decisions.
I always format / install. NEVER upgrade. Keep it nice and clean. too many places crap can get lost or dup'd. But if u mean going from older version to a new version, it's generally Price Having to re-install everything again. edit: This is referring to Windows OS, not linux, etc.
I did a job a few years ago performing an "assessment" of a small manufacturing company's network infrastructure. During that work, I discovered that their ERP system had never been backed-up. Unbeknownst to them, their former IT contractor configured Backup Exec for daily full backups but never scripted any type of "dump" or stop / start of the database ...
Anything that will run Windows 8 is already 64-bit capable, unless you happen to have some first-generation Intel Atom netbooks (and I doubt that very much). That's about the only thing I can think of. AMD released its first 64-bit capable Opteron in 2003; and since then virtually every processor they have made has been 64-bit capable. Intel was a year ...
Do not do this. Two different installations of Windows can not share one name in Active Directory. They must have different names, else the latest installation (relative to joining AD) will overwrite previous ones. Sharing an IP is fine, and may be default depending on your DHCP server (it's somewhat common to offer the same IP if the request comes from the ...
I don't consider BSD to be quite as mature as Linux on the Desktop but for servers it's rock solid. Whether you want to install BSD or not depends entirely on what you use your machine for. While many things are similar to Linux many things are different too. However here is a run down of the different BSDs OpenBSD : One if it's mail goals is to be the ...
Chris is right. To expand on his answer a bit, the computer's "name" is something that is rarely used by AD. It is simply a human-readable representation of the object. For most operations, AD uses the Security Identifier (SID), which is a GUID comprised of components that represent the domain and the relative identifier of the object. When you join a ...
Do you have a spare system? If so, openfiler or FreeNAS have good reputations for being made specifically for this task. Easy to maintain, it's made to be used as a network storage device, has features available like software RAID and the ability to maintain it from a web interface, and you can expand storage relatively easily.
In the Linux world, distributions tend to be lacking in that... cohesive feeling. They are often built in a decentralized manner, which tends to lead to this. The BSDs are usually managed by one person, so you get the feeling that each variant is an actual product that had a lot of planning behind it. Things work together very well, and all components are ...
Once in the olden times, one of our senior admins left our organization and turned over responsibility for the "document imaging system" to me. I was low man on the team, inexperienced, and eager to jump into anything. It was like the old Coke commercial with Mean Joe Green...I was totally stoked to become the primary (only) admin on a customer-facing ...
This link VMware Virtualization seems to be saying that running a virtual machine and spreading your applications between OS's is more efficient than otherwise. How can this be true? It's true because, if you look closely at most servers (but not all)...you'll see they are idle. Those are idle resources that are doing nothing other than ...
BSD is generally considered secure by default, by disabling all but the core services. It's also very stable, you can tell this by looking at one of the many uptime monitoring services. Be warned however, that Linux isn't the same as BSD...there is a learning curve, so don't expect to jump straight into it. For example you'll find all the core commands, ...
A process handle is an integer value that identifies a process to Windows. The Win32 API calls them a HANDLE; handles to windows are called HWND and handles to modules HMODULE. Threads inside processes have a thread handle, and files and other resources (such as registry keys) have handles also. The handle count you see in Task Manager is "the number of ...
both are unix based and supports the POSIX API but the kernel implementation is completely different. the Solaris (and OpenSolaris) kernel supports some interesting features not supported by the Linux kernel, like ZFS which is probably the best file system at the moment in any operating system, and Zones which allow you to create lightweight instances of the ...
It depends on the server and what it will be used for. If the server will house a particular software package, such as Oracle, ask the vendor what they recommend. What will be easiest for them to support? What OS has the best benchmarks for the software in your use case? Do you have staff who can work with that OS? For generic servers, go with whatever ...
I really like /usr/ports. This isn't to say that I don't also really like apt-get, but it's a pleasing feeling to know that your installs are being built on and for your particular machine, with any optimizations you felt like throwing into the makefile defaults. How much of the perceived benefit of that is superstition, I haven't done the research to find ...
*BSD is a complete OS, meaning the kernel and the userland is developed from the same source tree, whereas Linux distributions are butchered together from various sources. This is why BSD systems feel much more cohesive and solid. Also better documented.
Just a few issues: Pro (Free)BSD: ZFS filesystem/volume management Dtrace for tracing/analysis Excellent and easy to find documentation (FreeBSD Handbook, OpenBSD FAQ, Manual pages are really good and do actually have useful examples) Clean and rock solid OS release upgrade process Separation of the core OS from other software ("Ports collection") BSD ...
about 12 years ago i started work as sysadmin at a medium-sized ISP, with about 30 staff working there. they'd never really had a real sysadmin before, just some people who thought they knew what they were doing (sometimes they were right, most often they weren't. overall, it's amazing the systems worked at all). the icing on the cake, though, was that ...
In the TrueCrypt GUI, choose the partion of the external drive, then select "Mount without Pre-Boot authentication" from the Tools menu. This will let you mount the volume as if it were an encrypted device without the boot loader (the difference just being a few offsets as to where TrueCrypt should attempt to decrypt the volume header from)
Windows 7 64-bit works fine for me on a 4Gb machine. Win2k8 64-bit also works fine in 4Gb. We're running SQL Server on several 2k8 4Gb 64-bit machines, the only problems we've seen are with SQL eating all available memory which can be solved by setting the maximum memory option.
As a Java developer, the big gotcha is there is no mainstream JVM for *BSD. Before everyone flames me out of existence, what I mean is, there is no current shipping JDK from Sun or any of the other major vendors (IBM, BEA/Oracle) so you will always be playing second fiddle to linux and window users.
m0nowall and Smoothwall are the two biggest I know of for turning an old PC into a firewall/router. I'd suggest digging through features and screen shots then playing with each a little bit.
It's an obsolete term, no one uses it in the context you're asking about any more. I would say that it's been obsolete since the early 90's: somewhere around that time, networking features became a required part of any OS.
Compatibility with Ancient Software/Hardware. If everything works under x64, I wouldn't bother with 32 bit.
