Acer Aspire 3004WLCi - A Quick Review

I recently found myself in need of a new laptop. With a tight budget and moderate needs, I knew it wasn't going to be easy to find a product that would do what I wanted and still be in my price range.

As a Network Technician and a Web Designer, I needed a machine that would have enough storage to store all my software, projects for my clients, and still be able to handle an occasional temporary operating system backup from a client's machine. The qualifying candidate also had to have a decent amount of RAM and a reasonably fast processor to keep up with the demands of multitasking and using Studio MX '04 on a daily basis.

At first, I checked the auction sites, the refurbished outlets, and the wholesale warehouses. I found a few good deals for under $500, but nothing that would handle the processing load that Studio MX 2004 would place on it. The average machine had 256MB of PC133 RAM, a 20GB HDD, and a 1.0GHz Pentium processor. Not too shabby for a student machine, but for daily service in the fields I work in, not nearly enough space or power to keep up with my demands.

I quickly realized that a new laptop would be needed in order to meet my needs. Realizing that most decent laptops are priced at over $1,000, I wasn't expecting a whole lot when I started shopping around. However, to my surprise, a local retail chain had a special running on the Acer Aspire 3004WLCi for $600 after a $150 rebate. This was the top end of my budget, but the specs were far more than what I thought I would find in this price range.

OK, before I go into the Pros and Cons of this system, let me first say this... As a Network technician, I'm a bit of a stranger to Acer products. I've seen them before, but I've never used them. In an industry dominated by Dells and HPs, Acer seemed more of an "off-brand" to me. With that in mind, I wasn't expecting a whole lot for my money. Fortunately, I was not disappointed, but neither was I entirely wrong.

Also, it is worthy to note that before I used this machine, XP Home was trashed in favor of XP Professional SP2 and I went through the system and performed several minor software performance tweaks on the operating system; all of which can be performed using the native Windows XP Pro utilities.

Pros:
The Acer Aspire 3004 WLCi is a reasonably powerful system for $600. Even at the original $750, this system is hard to beat in the performance department. The Sempron 3100+ processor is surprisingly fast and capable. It handled running Dreamweaver MX 2004, Fireworks MX 2004, Microsoft Word 2003, Microsoft OneNote 2003, Firefox 1.5, Internet Explorer 6.0, Opera 8.5, Resize Browser, CPick, Java JRE, NOD32 Anti-Virus, Hotmail Popper, and several system services and minor utilities running in the background simultaneously and didn't complain or produce any unacceptable sustained CPU usage spikes. This is partly due to the generous and fast 512MB of DDR333 RAM, but even so, the processor surprised this long-time AMD user.

The 60GB hard drive provides an ample amount of storage for average users. It is on the lower end of my requirements, but sufficiently large enough to handle all my installed software, over 12GB of service software needed for service calls, all my client projects, and it still has enough space left over to easily accommodate a 20GB client system backup.

In addition, this system has a very good Broadcom WiFi controller. In my 3 story townhouse, which has excellent insulation, this system can be used anywhere in my home with a signal strength of "Very Good" to "Excellent".

The system is ergonomically laid out. I have rather large hands, and most modern laptops are entirely too small for me to realistically use for any extended period of time. Usually, within 20 or 30 minutes, my wrists and hands begin to ache from trying to maintain a very unnatural position in order to type the documents I'm working on. Not so with the Aspire 3000 series. These laptops have a relatively large chassis with a keypad that is almost perfect for someone with large hands. I've actually found that I can type nearly as fast (roughly 35wpm) on this laptop as I can on my desktop system that has an ergonomic split keyboard (40wpm).

Cons:
If you're looking for a Multimedia system, or if you plan to do any graphics intensive gaming, keep on looking; this system is not for you. Even with the widescreen WXGA display, this machine is not well suited for watching DVDs. The integrated video controller is only acceptable and the monitor requires a lot of "fiddling" with in order to find the "just right" position for viewing. Furthermore, the glare on the screen of this unit is terrible. I've found that in most brightly lit rooms I'm spending more time straining my eyes to see past my own reflection. Also, the viewing angle is unimpressive. If you try to view the screen from anything greater than 15 degrees in any direction, you're either looking at a washed out or negative variation of the original. I've never been a big fan of LCD. I've always felt that a high quality CRT always looks better, but this screen is more reminiscent of a LCD of three years ago than a brand new product.

The integrated audio and video controllers are a definite sore spot as well. I've always preferred expansion controllers over integrated controllers, but in this price range, I knew I would be stuck with the so-so quality of an integrated controller. No surprise here. As usual, the quality and performance is sub-par with these controllers, but for my needs, they do the job. However, if you plan on listening to any audio playback on this machine, you had better pack a quality set of headphones. The tiny speakers on this machine are terrible sounding. Again, no big surprise.

Now, about battery life. I don't know who was in charge of defining this aspect of this machine, but they need a checkup from the neck up. Battery performance on this machine is absolutely unacceptable. Unless you tune the system down significantly, it is very difficult to squeeze more than an hour of real usable time out of this system's battery life. The manufacturer states that it will run for 1.5 hours on the battery. I've never been able to get more than an hour out of the unit. In this day and age, this is not acceptable. Fortunately, there are very few occasions when I need to use this system where I'm not close to a power outlet.

My only other major complaint is the lack of expandability of this system. You get two SODIM memory card slots (filled with 256MBx2 sticks from the factory), three USB 2.0 ports and a Type II PCMCIA slot on this machine, and that's it. No internal expansion capabilities, no firewire, no serial or parallel connections, and you cannot swap out the combo drive easily. Given the price range of this system, I'm really not surprised, but I am a bit disappointed. Fortunately, there are an abundance of USB adapters available that allow me to do whatever is needed.

Summary:
If you just need a basic system for work or school related tasks the Acer Aspire 3004WLCi is a solid performer that can handle average use with ease. I would definitely recommend this unit to college students or traveling professionals who need an inexpensive, user-friendly laptop, but who do not plan on using their laptop on batteries very often, or who do not intend on playing many games or movies. For the price conscious consumers out there, this system is definitely worth the money. In my humble opinion, you get more than what you pay for, but not by much.

How To Recover Lost or Deleted Data Files: Data Recovery Software Information

Have you heard of data/file recovery? The definition of the term Data Recovery is "..Making previously lost or damaged data available again.." A data recovery software or method can help us recover destroyed data e.g. an accidentally deleted file. It happens all the time. You delete an important file on your PC and send it to your recycle bin by mistake. You realize what you've done only after you've cleaned the contents of the recycle bin.

What do you do now?
That file you deleted was so important. Fortunately there are lots of methods (Data Recovery Methods) and software (Data Recovery Software) available to help you get your lost files back.

Let's start by mentioning some possible reasons for the loss of data:

* You accidentally delete an important file. Then you immediately shred the contents of your recycle bin
* During today's system crash some files just disappeared and cannot be located or accessed
* You format your hard drive but then you remember those important .zip files previously stored in the newly formatted empty medium.
* A power outage prevented some files from being written to the hard disk.
* Data loss can also occur due to physical damage of the storage media. For example the surface of your CD-ROM may be scratched off or your hard disk may suffer from all kinds of possible mechanical failures.

..and the list goes on.

Is Data Recovery Important?
Data recovery is a very misunderstood concept. A lot of people may not even be aware of the existence and the importance of data recovery. Maybe they think of it on a personal level. The truth is, lost data causes financial disasters to companies all over the world. The cost associated with computer downtime and lost data is enormous (several million dollars) for businesses.

How to deal with data loss?
Losing files is easy but recovering them can be difficult. If the loss was due to physical damage then you need someone with experience, a hardware technician or something. It wouldn't be wise to try to overcome hardware failures alone unless you are a professional.

Now, if the loss of data was due to logical failure or human error then the solution is data recovery software. The data recovery software should be able to:

- Undelete files even after you've shred the contents of your recycle bin
- Recover files after you've been infected from a malicious threat (trojan, worm or other virus)
- Recover files from reformatted hard disks or after your system crashes or your hard disk fails
- Recover all types of files (all kinds of documents, images, music, videos, email messages, zipped files etc)
- Recover data from all types of storage mediums (hard disks, external drives, CD-ROM, usb drives, floppy disks etc)
- Recover files easily and successfully. Should be user-friendly allowing someone with no data recovery skills to use it
- Take/create backups of critical system files or files you choose

The best way to avoid data loss is to start taking backups of your important storage mediums. Either create backups of data on CD-ROMS or use an external drive or zip drive to back up your critical files. If you want to go further look for software that automates the process of backing up and storing your data. These programs are kind of "set and forget". You set it up to take backups every hour or every day or month etc. and let the software do the rest.

Crime Fighting Computer Systems and Databases

As crime globalizes, so does crime fighting. Mobsters, serial killers, and terrorists cross state lines and borders effortlessly, making use of the latest advances in mass media, public transportation, telecommunications, and computer networks. The police - there are 16,000 law enforcement agencies in the Unites States alone - is never very far behind.

Quotes from the official Web pages of some of these databases:

National Center for the Analysis of Violent Crime (NCAVC)

Its mission is to combine investigative and operational support functions, research, and training in order to provide assistance, without charge, to federal, state, local, and foreign law enforcement agencies investigating unusual or repetitive violent crimes. The NCAVC also provides support through expertise and consultation in non-violent matters such as national security, corruption, and white-collar crime investigations.

It comprises the Behavioral Analysis Unit (BAU), Child Abduction and Serial Murder Investigative Resources Center (CASMIRC), and Violent Criminal Apprehension Program (VICAP).

VICAP is a nationwide data information center designed to collect, collate, and analyze crimes of violence - specifically murder. It collates and analyzes the significant characteristics of all murders, and other violent offenses.

Homicide Investigation Tracking System (HITS)

A program within the Washington state's Attorney General's Office that tracks and investigates homicides and rapes.

Violent Crime Linkage System (ViCLAS)

Canada-wide computer system that assists specially trained investigators to identify serial crimes and criminals by focusing on the linkages that exist among crimes by the same offender. This system was developed by the RCMP (Royal Canadian Mounted Police) in the early 1990s.

UTAP, stands for The Utah Criminal Tracking and Analysis Project

Gathers experts from forensic science, crime scene analysis, psychiatry and other fields to screen unsolved cases for local law enforcement agencies.

International Criminal Police Organization (ICPO) - Interpol's DNA Gateway

Provides for the transfer of profile data between two or more countries and for the comparison of profiles that conform to Interpol standards in a centralized database. Investigators can access the database via their Interpol National Central Bureau (NCB) using Interpol's secure global police communications system, I-24/7.

Interpol's I-24/7

Member States can directly input data into the information system in compliance with their national procedures, and Europol can directly input data supplied by non EU Member States and third bodies. Also provides analyses and indexing services.

Microsoft Certification: The New MCTS Tracks And Exams

Microsoft is revamping its certification tracks, and will eventually retire the familiar MCSE certificatons. The new certification setup is much like Cisco's, where there are specialist certifications to go along with the more general CCNA, then mid-level certifications such as the CCNP, and then a more-advanced practical exam modeled somewhat after the coveted CCIE certification.

Microsoft's new specialist exams are the Microsoft Certified Technology Specialist (MCTS) exams. As of March 2006, there were five separate MCTS Tracks. Three of them deal with .NET Framework 2.0; these are the Web Application, Windows Applications, and Distributed Applications certifications. Each of these separate certifications requires the candidate to pass two exams. There is also a one-exam SQL Server 2005 certification, as well as a BizTalk Server 2006 single-exam certification.

The initial question is "Why is Microsoft doing this?" According to their website, MS feels that IT hiring managers today have a tough time deciding which computer certifications best identify job candidates who best meet their needs. I know it's easy to take verbal shots at Microsoft (it'll be an Olympic sport one day), but this new series of certs does have appeal for hiring managers, which can only help qualified candidates. Instead of the more-general MCSE, which does still suffer from the overcertification of NT 4.0 MCSEs back in the day, these more-specific certifications will make it easier for the job candidate to prove that they can do the job - and easier for the hiring manager to make an informed decision.

Microsoft hasn't announced the track that will eventually replace the MCSE, but this track will be revealed with the next client-server Windows release. It's up to you to stay informed of these changes, so I recommend you visit Microsoft's certification website often. "I didn't know" isn't much help once a certification expires!

Cisco CCNP Certification / BSCI Exam Tutorial: An Introduction To BGP

When you're studying for the BSCI exam on the way to earning your CCNP certification, it's safe to say that BGP is like nothing you’ve studied to this point. BGP is an external routing protocol used primarily by Internet Service Providers (ISPs). Unless you work for an ISP today or in the future, you may have little or no prior exposure to BGP. Understanding BGP is a great addition to your skill set – and you have to know the basics well to pass the BSCI exam.

Note that I said “the basics”. BGP is a very complex protocol, and when you pursue your CCIE, you’ll see what I’m talking about. As with all things Cisco, though, when broken down into smaller pieces, BGP becomes quite understandable. You will need to know the basics of BGP as presented in this chapter to pass your BSCI exam – so let’s get started.

BGP Defined:

“An Internet protocol that enables groups of routers (called autonomous systems) to share routing information so that efficient, loop-free routes can be established. BGP is commonly used within and between Internet Service Providers (ISPs).”

There are a couple of terms in there that apply to the protocols you’ve mastered so far in your studies. The term “autonomous system” applies to IGRP and EIGRP as well as BGP; you’ll be indicating a BGP AS in your configurations just as you did with IGRP and EIGRP. And we’re always looking for efficient, loop-free routes, right? As it did with IGRP and EIGRP, "autonomous system" simply refers to a group of routers that is managed by a single administrative body. An autonomous system will use an Interior Gateway Protocol (IGP) such as OSPF or EIGRP to route packets inside the AS; outside the AS, an Exterior Gateway Protocol (EGP) such as BGP will be used.

BGP shares some characteristics with some routing protocols you’ve already studied. BGP supports VLSM, summarization, and CIDR. Like EIGRP, BGP will send full updates when two routers initially become neighbors and will send only partial updates after that. BGP does create and maintain neighbor relationships before exchanging routes, and keepalives are sent to keep this relationship alive.

BGP has some major differences from the IGPs we’ve studied to this point. You’ll hear BGP referred to as a path-vector protocol. As opposed to distance-vector protocols that exchange relatively simple information about available routes, BGP routers will exchange extensive information about networks to allow the routers to make more intelligent routing decisions. This additional BGP path information comes in the form of attributes, and these path attributes are contained in the updates sent by BGP routers. Attributes themselves are broken up into two classes, well-known and optional.

BGP also keeps a routing table separate from the IP routing table.
We'll take a look at BGP attributes in future BSCI tutorials. In the meantime, keep studying!

Cisco CCNP / BSCI Certification: Introduction To ISIS Terminology

When you're studying to pass the BSCI exam and earn your CCNP certification, you're going to be introduced to ISIS. ISIS and OSPF are both link-state protocols, but ISIS works quite differently from OSPF. You must master these details in order to earn your CCNP.

One of the major differences between OSPF and ISIS will be evident to you when you first begin your BSCI exam studies, and that is the terminology. ISIS uses terms that no other protocol you've studied to date uses, and learning these new terms is the first step to BSCI and CCNP exam success.

First off, what does "IS" stand for in "ISIS"? It stands for "Intermediate System", which sounds like a group of routers. As opposed to Autonomous Systems, which are logical groups of routers, an Intermediate System is simply a single router. That's it.

You'll also become familiar with End Systems, referred to in ISIS as an "ES". The End System is simply an end host.

ISIS and OSPF both use the concept of areas, but ISIS takes a different approach to this concept. ISIS routers use three different types of routing levels, according to the area a router has been placed in. Level 2 routers are connected only to the backbone and serve as a transit device between non-backbone areas. Level 1 routers are totally internal to a non-backbone area.

ISIS uses both Level-1 and Level-2 Hellos, meaning that the two types of routers just mentioned cannot form an adjacency. Luckily for us, there is a middle ground, and that is the Level 1-2 router. These routers connect non-backbone areas to backbone areas. L1-L2 routers keep two separate routing tables, one for L1 routing and another for L2 routing. This is the default setting for a Cisco router, and L1-L2 routers can form adjacencies with both L1 and L2 routers.

Part of the challenge of learning ISIS is getting used to the differences between ISIS and OSPF. Keep studying the terminology, master one concept at a time, and soon you'll be a master of ISIS and a CCNP to boot!

Cisco CCNP / BSCI Exam Tutorial: 10 ISIS Details You Must Know!

Earning your CCNP certification and passing the BSCI exam depends on knowing the details of many Cisco technologies, ISIS chief among them. To help you prepare for exam success, here's a list of ISIS terminology and basic concepts that will help you pass this tough exam. Enjoy!

ISIS Terms:

Domain: section of the network under common administrative control

Area: logical segment of the network composed of contiguous routers and their data links

Intermediate System: A router.

End System: A host device.

The four levels of ISIS routing:


Level 0: ES-IS routing in the same subnet.

Level 1: IS-IS routing in the same area.

Level 2: IS-IS routing in the same domain.

Level 3: Inter-domain routing performed by InterDomain Routing Protocol (IDRP).

ISIS Adjacency Possibilities:


L1: Can form adjacency with any L1 in the same area and any L1/L2 in the same area.

L2: Can form adjacency with any L2 in any area, and with an L1/L2 in any area.

L1/L2: Can form adjacency with any L1 in the same area, L1/L2 in any area, and L2 in any area.

A router interface’s SNPA (Subnetwork Point Of Attachment) is its highest DLCI number if it’s on a Frame network, and its MAC address if the interface is on an Ethernet segment.

ISIS Hello Types:

ESH: ES Hello – Sent by End Systems to discover a router.

ISH: IS Hello – Send by Intermediate Systems to announce their presence. End Systems listen for these.

IIH: IS-to-IS Hello – Send by one IS to be heard by another IS. These hellos makes IS-IS adjacencies possible.

Best of luck on your CCNP exams!
