btw, for a cheap managed switch I would have no problem recommending the HPs. I've had good luck with several Procurve models in the 18xx, 19xx , 28xx, and 29xx series in L2 applications. No experience with their 10G equip though.

What's the application? what are your availability requirements? I'm pretty happy with the Cisco 4948E-E or 4948E-F models we have. While they're overkill for what you stated (IP4/IP6 routing, ACLs, etc @ 176 Gbps, redundant PSU), they go on the gray market for between $1k and $1.5k US.

That's not something I currently have in my arsenal, but I think it'd be good to add. Thanks for the recommendation.

I rented a Canon EF-S 17-55mm f/2.8 IS from LensRentals.com to do family portraits this weekend (I have a T2i body). I was very pleased with the results.

I didn't care for 8. Personally, I'd skip it.

Thanks, as I only have 4GB of RAM in that laptop I'll probably leave well enough alone.

It's been a while, but the uni bookstores would often carry the educational versions of software. In your case, it sounds like you've done the pricing research and found the edu cost is the same for photoshop. When I was studying at a local community college for some continuing learning in IT...

The two finger tap method works well for me ...so well I keep trying to do it on Windows.

Forgive my ignorance, but is it worth installing this software? I just upgraded a laptop (that has an 840 pro) to windows 10 and only needed to install MS office and the latest trackpad drivers. Everything else works great and the system is pretty snappy (and very clean software wise).

Thanks for the (empathetic) laugh. My primary machine at home is now an iPad. I also use a macbook air if I need to do something that requires much typing. Photos are processed on a PC just because I like the software I happen to have installed there. However, the same software would run fine on...

I have noticed this to some extent as well. It seems like a "60 watt replacement" LED is brighter than a "60 watt replacement" CFL. I think it has to do with age, inaccurate (fuzzy) ratings, the color temperature (and how the bulb achieves that average color temp), CRI, etc. You'll also have to...

I have to agree that it seems incongruent that we provide a corporation with the benefits of citizenship (because it's made of up citizens), yet allow it to evade the penalties we would otherwise apply to citizens. An example that comes to mind is a mob lynching. If a mob lynched an accused...

The 3 watts of the Roku3 and 2 watts of an apple TV was very impressive and one of the things that allowed these devices to be placed almost anywhere with passive cooling. The Roku4 says 12.4 watts and the case is much larger. I wonder if they'll have any overheating problems or if they've had...

I guess it all depends on the application. 14.4k was fine for a text based internet and faxes. Websites with static images were a drag on anything below 56k+. Interactive websites and what we now call SD video probably requires 2-3+ Mbps using modern codecs. If you want HD video you'll need...

The engine bay in my '99 NB is about half empty - plenty of space. No idea what the newer ones look like, although most new cars cover the bay (over and under) with plastic covers. I see they also moved the battery under the hood (previous versions kept it in the trunk). There's a great pic of...

I want one. I own a 1999 miata, which I purchased with hopes of being a hobby car, but never did much to. I drive it when the weather is nice and store it in the winter. I'd love to have a newer one and, if I didn't need a car seat, would probably drive it year round (would need a set of snow...

Many providers (my employer for example) used to provide a /24 with each dedicated connection as a matter or course; Those were T1's generally. We also offered ISDN, but IP addresses had to be requested. A class C per (business) customer was pretty typical, regardless of connection type. In a...

I was recently describing to a guest at my work how to logically address a network, using a small ISP with a handful of sites as an example, and found it much simpler to explain using IP6. Once all the vendors settle on which standards to use (SLAAC/ND vs DHCP6) and the bugs get worked out, I...

I don't understand either. The ubiquiti power brick I have is similar in size to that of any other hub/switch/modem/router. The benefit of the PoE type brick is that the power brick can be 1 foot away or 100. If your router/switch is in another room, just connect the brick there and you don't...

Working in the website hosting biz, we've seen several WordPress (and similar CMS) attacked exactly as Merc describes. It's not a targeted attack usually, just a spider looking for vulnerable WP installations. Malicious PHP is added to existing legitimate scripts or new PHP scripts are added to...

I tested today with a macbook air and found the range to be roughly 50%-100% better than with an iPhone. Interestingly, the signal strength indicator stays very high, even when at the outer edge of the usable range. My interpretation of this is that the AP is transmitting plenty loud and it's...

My research concurs with Merc's experience. I anticipated using the included power injector because the wiring in my application was not up to the standards required of a PoE deployment. The included injector worked fine. Regarding range, I left the UAP to auto channel/tx level and am seeing ~...

How are you liking the Ubiquiti gear? I was recently given a project at work that involved moving/replacing two consumer APs and a pfSense firewall and decided to replace the two APs with a single Ubiquiti UAP. First impressions on the software and the hardware are good. I'd like more time to...

I think it just took us a year or two to realize their faults; the faults were present from the beginning. For a home user who wants to worry less about power outages and will likely replace the UPS when a battery ages out, the CyberPower units may represent a good value. For someone looking for...

At work we purchased several of the CyberPower 1500 AVR units. We threw them out after a year or two. First, the units would often trip (they shut off completely) when reaching about 75% of the stated load rating, even when on line power. Second, some equipment connected to them would reboot...

I recently replaced a 15" XPS laptop with a mac book air. I thought the 13" screen might be a compromise, but I'm very surprised at how legible the new laptops are. After experiencing the portability of the smaller, lighter units I don't think I'd go back to a 15". overall, I'm very pleased...

Sounds like you have it covered. About the only additional thing I can suggest is verifying the current quality and draw using a kill-a-watt (before and after the UPS). I've never used a gold rated PSU (silver at best) - so no experience as to whether they're any more picky or likely to...

I agree with the comments that an on-line or AVR UPS might help. An AVR UPS will buck high line voltage or use the batteries to supplement low voltage to condition the power to a reasonable level and will switch completely over to battery power when needed. They also tend to provide a better...

I can handbrake a DVD to h.264 in 15 minutes on an i5 750... of course, that's using one of the profiles optimized for an iPad. Your encoding settings will have a big result on speed. It may be more cost effective to look at the 'constant quality' (quality vs bitrate trade-off) setting or the...

When the +4 12v connectors first came out, I used an adapter cable that came with the motherboard to allow it to connect to a standard ATX power supply's 4-pin molex connectors. Unfortunately, the cable was cheap and I wasn't paying close enough attention and plugged the molex connector in...

All of the applications you mentioned should honor DNS TTLs. You can reasonably set your zones' TTLs to 30min, giving you an average failover time of 15 min, 30 min worst case. If you can use cnames on the 15 zones pointing back to a single zone, this would simplify the failover process: 1 zone...

Cacti is a good tool for snmp monitoring. Lots of pre made templates, threshold alerting, reports, etc. there's a pre-made distribution - cacti-ez if you want to get started quickly.

What services/applications are provided by these domains (www, email, VoIP, etc). And how seamless does the failover need to be ( instant/completely transparent, couple minutes/clients might need to refresh or restart, couple hrs/clients will need to try again later) ? Can you provide an...

Teaming is only appropriate if the two NICs are connected to the same switch. Unfortunately, Linux exhibits this odd default behavior whether the NICs are connected to the same switch, different LAN segments, or even different ISPs. It's ultimately caused by the fact that the Linux kernel sees...

On that first screenshot you can usually hit the space bar to change the drive type from off to auto (or some better choice). Was that not working?

I thnk chewy hit the nail on the head. The biggest difference between dell (or whoever's) drives is that they make them smaller than the original manuf so you can swap in a new drive (from whatever manuf dell chooses that day) and not worry that your array that consisted of 4x147gb drives will...

Sounds like you know everything necessary for the perc. The dell servers were offered with SSDs and there are many independent reports of people adding their own, so they should work. I've never had trouble with sata drives on any SAS perc( including the 6), I'm going to guess it is either a...

I also assumed you were familiar with the perc and have setup raid arrays in them before.

That would be my suggestion also, assuming you didn't need hot swap or raid. My guess is the data or power connector isn't seating well against the sas backplane. I'm assuming you're not using an interposer board and that you are using the screw holes for SAS drives and NOT the ones marked...

Apple has always been an early connector adopter, usb, dp, dvi, mini dvi, and now lightning. No surprise there. When they pickup a new connector they usually drop the last generation one. We don't hate other folks for phasing out ps2, d-sub vga, etc. the lightning connector used on the latest...

That's the whole point behind PI (provider independent) ip addresses. Arin, or another RIR, assigns you ip space. You can then use your ip space on any ISP you choose or even on several simultaneously. You can move your Internet connection to another ISP at any time without renumbering devices...

There were initially some ranges reserved for non-routable v6 addresses (site local, fec0::) but that would inevitably lead to nat which breaks one of the basic tennants of ip (end to end routing), so site local v6 space was deprecated. If you want something private, just put it behind a...

Thanks

Ip6 is not an upgrade to ip4. They are separate and meant to live side by side. Ip6 stacks can only talk to other ip6 stacks, ip4 w/ip4. There are ways to get an ip4 only machine to talk to an ip6 only machine ( and vise versa), but it involves a proxy server (that supports both) providing...

2607:5800::1 - not that different from 64.35.208.1 I actually find it more helpful, because I can address with a little more flexibility. E.g. Site A could be 2607:5800:a:: and site B 2607:5800:b:: and know that I'll never run out of possible sites or addresses at a site With ip4, addressing...

Btw, I think the current estimates are that arin will be out of ip4 addresses next year. Hopefully they will crack down on the tier 1s who have been allocating addresses to customers and not deallocating when the customers leave. We had 10+ /24's from a tier 1 that they continued to state were...

That sounds correct for a /20. That probably also includes an as number and arin voting rights. Ip4 addresses are cheap. At some allocation sizes I think it works out to ~ $0.25 per ip per year. It's amazing that some folks spend thousands on nat solutions that break connectivity in order to...

You mentioned the hw needed, but I haven't seen any consideration regarding network bandwidth, performance, or availability. Are these services accessed by your staff only or is it for clients? All moving the servers in house incur any additional wan costs? Will it save on wan costs? Why are...

I put together a pfsense box on an otherwise end of life dell power edge 2850 a couple months back. All hw including the perc was supported. Client was replacing a Cisco 26xx series router working as the office firewall. The new firewall has 1 wan interface and 2 LAN interfaces with 4 LAN...

Depending on your ISP, they may also provide you with an LOA to announce ip ranges they've swip'd to you via BGP. This would require a minimum of a /24 assignment. Pro: no arin red tape or annual reg fee Cons: ISP may decide to renumber you later on, you are also stuck with that ISP or forced...
