Leopard vs Vista

Mac's Leopard vs Microsoft Vista

 

From the start, Vista crashed noticeably less than XP Pro with SP2; it just doesn't work with 50 percent of new software—a year after its shrink-wrapped release. Here's the point, in case any Apple reps missed it: Microsoft has delivered clear improvements in stability over time—a feat you'd think Apple might want to emulate, A month of using Leopard with the same software as on Tiger and the OS has dumped six times.

Botnet Computers

Botnet computers

 

More than 1 million computers in the last five months have become part of robot networks, or "botnets," in which hackers take over computers without their owners' knowledge and use them in criminal campaigns, the FBI said Thursday. The bureau in June announced Operation Bot Roast to stop this emerging type of cyber attack, which the FBI estimates has resulted in $20 million in losses and theft.

 

More than 1 million computers were infected with botnets when the FBI launched Bot Roast, and another million have been identified since then. Industry numbers suggest there are millions more.

Telecomputing in the Classroom

Keys to Successful Telecomputing

by Al Rogers, Yvonne Andres, Mary Jacks, and Tom Clauset

[This article appeared in The Computing Teacher in 1990, Volume 17, Number 8, pages 25-28.]

A condensation of this article, How to Design a Successful Project, has been widely circulated on various newsgroups and lists ever since.

For some teachers, telecommunications expands the horizons of their classroom, opening the doors to real audiences and exciting interactive activities from locations around the country and the World. These teachers know its capacity to motivate students and involve them in productive learning experiences.

Many others, however, fail to realize this potential power. For every successful long-distance learning experience you hear about, you are bound to hear others testify, "I tried that, and it didn't work."

Articles and conference presentations are often guilty of hyperbole. The author or presenter has had successful telecomputing experiences and relates glowing reports of life-changing online communications with distant colleagues, and how these experiences improved their classes. It is easy to be beguiled with such evangelistic accounts. Yet many novices are often frustrated, discouraged, and disillusioned with the actual use of this "powerful, exciting" technology.

Much of this frustration is due to the learning curve imposed by the current state of technology in the classroom. There are still a myriad of technical obstacles to overcome in preparing to use computers, modems, and phone lines in the classroom.

A more damaging source of frustration, however, has to do with the ways teachers think about how telecomputing technology ought to work, and what they expect from it. Most computer using teachers expect instant results as they implement technology: plug the computer in, boot the word processor, and begin writing. Plug the printer in and begin printing. Plug the modem in and dial an information service. They expect to announce their presence on a network, request a "computer pal" and instantly have their students involved in meaningful exchanges. When, two weeks later, they have not received even one reply, they are understandably disappointed in the "promise" of this technology.

These teachers haven't yet realized that installing their modems, learning their terminal software, and getting connected online are simply the preliminary and easiest parts of their task. Having dealt with these technological components, they must now depend on other people to participate with them in an interactive project. And, unlike their fairly predictable experience with technology, this new social realm is vastly unpredictable and even sometimes temperamental.

Keys to Successful Telecomputing

On the FrEdMail Network, we have evolved a number of guidelines and principles that have led to many successful collaborative projects involving hundreds of classrooms and thousands of students. Like many aspects of successful teaching, we have found that planing is the key to success.

The first rule of successful online learning activities is to avoid starting with the stereotypical pen pal activity.  Jim Levina pioneer researcher in electronic networking at the University of Illinois, has documented the reasons why pen pals are not effective for eliciting high-quality networking activity. While this format can result in some positive benefits for individual students, pen pal activities are often disappointing as a whole class activity.

How then does a teacher take advantage of the much-vaunted "promise" of telecomputing technology in the classroom? The guidelines presented below have been validated in numerous highly successful classroom-based projects on the FrEdMail Network. These guidelines, along with the sample "Call for Collaboration" in the sidebar to the right, will help guide you through a successful online learning experience with your students.

1.      Design a project with specific goals, specific tasks, and specific outcomes. The more specific, the better; the more closely aligned with traditional instructional objectives, the better.

2.      Set specific beginning and ending dates for your project, and set precise deadlines for participant responses. Then make a timeline, and provide lots of lead time to announce your project. Teachers feel more comfortable participating in projects that have a definite goal and an ending date. Experience shows that peak use on an educational network is geared to traditional cycles of the school calendar. October through December, February through May, and July (with summer school) are very busy times on the network. However, most of the successful networking activities were planned, and announcements posted, six to eight weeks before the actual project is to begin. You also may find that you need to advertise for participants several times, and thus the more lead time the better.

3.      Phased deadlines establish a sense of accountability to the other participants in the project and make it easier to secure follow through. Even if the teacher is inclined to drop out, students who know the deadlines will often hold their own teachers accountable to complete the project.

4.      If possible, try your project out with a close colleague first, on a small scale. This can help you overcome both technical problems as well as problems with the basic project design. You will find that having a sympathetic colleague available to discuss and solve problems will be a big help. You'll also find that in some of your early networking experiences, you may have to mail the disks containing student writing rather than telecommunications.

5.      Request collaborators by posting messages on electronic bulletin boards, and by sending out flyers if possible.

6.      Give specific information about your project in the call for collaboration:

o       Goals and objectives

o       Your location

o       Grade levels desired

o       Contact person

o       Timeline and deadlines

o       How many responses you would like

o       What you will do with the responses

7.      Provide examples of the kinds of writing or data collection that students will submit. This is important to the success of the project.

8.      Find responsible students and train them to be part of your project. You're probably already doing this if you are using technology in the classroom. This will be a big time saver.

9.      At the conclusion of the project, follow through on sharing the results with all participants. If you publish any student writing, send a hard copy to all who participated. Have your students collaborate on writing up a summary that describes the project, what they did, what they learned, and what changes they would make. Post that message on the network for all to see (not just the project participants). Finally, have your students send a thank-you message to all participants. You might also want to send a hard copy of your summary and a thank you to the principal of each school that participated. This can be an effective way to reinforce one another in our ongoing efforts to educate others and validate our use of this technology.

Networking activities can encompass a wide variety of project ideas, especially projects in which students can collect data and information for use by other participants on the network. As teachers gain skill and comfort with networking technology, and as networks become more accessible to both teachers and students, classroom telecomputing technologies will grow in importance as a tool for involving students in interactive projects that will motivate them to improve their skills and learn about the world around them.

Editor's Note

FrEdMail is a free educational messaging network joining 120 local bulletin boards. The coordinators of each board work together in a system-wide conference, and all participants are asked to contribute to the activities of the network. There are several network-wide open conferences: an IDEAS exchange for teachers, and KIDWIRE, a bulletin board to post student work, ORILLAS for multilingual project, and others.

Map & Globe Skills on the FrEdMail Network

With local access to a continent-spanning network of FrEdMail electronic bulletin boards, our fifth-grade teachers in the Winston-Salem/Forsythe County Schools were anxious to develop a social studies telecommunications project that would give their students practice in map and globe skills with a particular focus on U.S. geography. Through teacher-to-teacher connections made earlier in the year, we learned that fifth graders across the country studied U.S. geography, and that map and globe skills often began as low as third grade and continued on into the seventh and eighth grades. Could we develop an exciting project that would lure students to reference books and maps and get them to practice their geography skills in a real-life context?

The result of our collective brainstorming was the spring, 1989 FrEdMail telecommunications project, "The Geography Game." Here is the call for collaboration as it appeared on FrEdMail.

Subj: US GEOGRAPHY GAME

From: BLADEN!WSALEM!TCLAUSET

GEOGRAPHY GAME

TEACHER GUIDELINES

The object of this game is to try to learn where the TEACHER

PAL classrooms are located; and, learn a little United States

geography at the same time.  The first part of the activity

requires that each classroom fill out the "Geography Game

Questionnaire" in this file and Email it back to the

project coordinator (TCLAUSET@WSALEM) by Friday, Feb. 10.  The

next week you will receive a file which will include the names

of city/state locations of all the classrooms participating in

the TEACHER PAL PROJECT.  In addition this file will contain

descriptions of these locations.  Your students must help you

to try to figure out which description goes with which

city/state listing.  The winning person or class is the one

who correctly matches up ALL of the city/state locations with

their correct descriptions.

PROJECT TIMELINE

1. Guidelines mailed out:  Monday, Jan. 30th

2. Your class' description of our city needs to be mailed in

   to  TCLAUSET by:  Friday, Feb. 10th

3. Geography game locations & descriptions will be put

   into Email by: Thurs, Feb. 16th

4. You have until this date to work on the game with your

   class.  You must mail in your class' answers by:  Tuesday,

   Feb 28th

5. Game results will be mailed out:  Thursday, March 9th

FILLING OUT THE DESCRIPTION FOR YOUR CITY

You might want to start with a whole-class discussion of the

game and go over the identifying characteristics of the 8

description items. Discuss latitudes, time zones, land forms,

points of interest, tourist attractions, state capitals, and

nearby rivers as needed.  Divide your class into groups of two

or three and give them each a question.  Have them do a little

research in the library or with the local maps to find the

answer to their question.  Come back together in a whole-class

discussion and elicit the answers to each group's question.

Have a student in the class act as a 'secretary' to compile

the answers.

Type up the 8 answers and Email them to TCLAUSET

(...BLADEN!WSALEM!TCLAUSET) by Friday, Feb. 10th.

The following is an example of 8 questions for a sample city:

City: Lancaster, Pennsylvania

1.  Latitude:40 degrees

2.  Time Zone: Eastern

3.  Winter: Cold & snowy! -High today: 40/Low: 20

4.  Dress: Heavy coats, boots, gloves, hat

5.  Closest River: Susquehanna River/gently rolling farmland

6.  Tourist Attractions: Amish farms

7.  Population: 386,600

8.  Direction from capital: Southeast

9.  Famous For: Home of former president James Buchanan;

                location of Franklin & Marshall College

PLAYING THE GAME

By Thursday, Feb. 16th a file containing the locations of each

of the classrooms in the TEACHER PAL project as well as an

equal number of location descriptions will be put into the

mail at SALEM.  You may want to gather a few materials for the

class so that students can break up into small groups to begin

the process of matching locations up with descriptions.

(Large United States map showing time zones & latitudes,

set of encyclopedias for individual state maps, AAA road maps,

Rand McNally Road Atlas, Almanac, etc.)

Run off enough copies of the city/state locations to give one

to each child in your class.  Print out the descriptions,

divide your class up into 4 or 5 groups and give each group an

equal number of the descriptions  You might want to set aside

two or three 20-30 min. "Research Periods" for the

groups to try to match up their descriptions with the

city/sate locations.

When each group has done the best job they can on the match

ups, type up a list, with each city/state listed with the

number which matches its correct descriptions and Email it to

TCLAUSET by Thursday, Feb. 23rd.

WHO WINS THE GAME

Within a week or two of the conclusion of the game, the

results will be mailed out to all participants.  The winning

classroom(s) will be the one(s) which is/are able to match the

most locations with their correct descriptions.

GEOGRAPHY GAME QUESTIONNAIRE

1. What is the latitude of your city?

2. In which time zone are you located?

3. Describe the winter season in your area. Include

   temperatures,

   precipitation, and seasonal dress.

4. List any prominent land forms in your area and name the

   closest river.

   How far are you from this river?

5. Name the points of interest or tourist attractions in your

   area.

6. What is the population of your city?

7. In what directions is your city from the state capital?

8. For whom or for what is your city famous?


Students enjoyed matching the descriptions to cities, and were successfully lured to maps and resource books in their classrooms and libraries. The matching-up process typically took two weeks. At the end of the project timeline the correct answers were mailed out, allowing each class to check for itself to see how close they had come to the true location descriptions. All in all, the project was a great success!

Here are a few comments from teachers involved in the project:

1.      From Ileen Wrenn in North Carolina: "During their free break time students would work on the game and try to figure out where the places were. Needless to say, they loved it."

2.      From Chippy Weavil in North Carolina: "I sent students home with instructions on how they should go about matching up the cities with the correct description. One student was the first to come in with the answers and got all of them correct! It was a fun activity and really got them looking at maps and pulling books off the shelves to read about places, especially those in California. Those were toughies. It also helped the class to work together and learn more about cooperation and compromise. I enjoyed listening to why some of them thought it should be one place over another---but, in the long run, the majority rules!"

3.      From Cathy Thurston in Illinois: "We had the kids start one day in groups in the library. Then they took the materials back to their room for a week. The teacher kept it on a back work table where the students could work on it whenever they had free time. She reports that they loved it--were very motivated by it--and went back wherever they could, with no prompting from her, to work on it. They asked her for maps daily. She says that in all the years she has taught, this has been the best map activity she's had! I initially thought it would be too hard for 3rd grade, but with a little help on latitude, they were fine."

Store.exe process uses max. memory

The Store.exe process max's out the memory on a server running exchange.

SYMPTOMS

You may experience all the following symptoms on a Microsoft Exchange Server 5.5 computer that is running the Exchange Server 5.5 Internet Mail Service:

An incoming SMTP e-mail message is not delivered. Instead, this message remains stuck in the Internet Mail Service queue.

The Store.exe process uses almost 100 percent of CPU resources.

You cannot stop the Microsoft Exchange Internet Mail Service

 

This problem occurs if Exchange Server 5.5 receives an e-mail message that has a corrupted font name

Scan Management Console

One of our clients use a network scanner that scans to a shared folder off of an XP Professional pc. They had said that the scans were not showing up in the folder after scanning so I logged into the pc and restarted the Scan Management Console which did not resolve the issue. I then looked at the server status and it had 1.9GB free space for the scans so I knew that they had not maxed out the memory. I noticed that the status of the scan management console said that the scan service was suspended so I went under computer management and restarted the service for the scan management console but when I reopened the utility it still said that the service was suspended. I clicked on the start menu and went to all programs and highlighted the scan management console and noticed that there were options under there to either suspend the service or to start the service, once I clicked on start the service all of their scans began showing up in the shared scans folder. Issue resolved.

In Vista, check or uncheck Store and display a list of recently opened files, and click OK.

Email disappearing from your inbox?

In Microsoft Outlook, why is my Exchange email disappearing from my Inbox at work after I read it at home?

If you have an Exchange server account, you have an Exchange server mailbox, which can store your email directly on the server. When your email is stored in your Exchange server mailbox, you can get to your stored email messages from any computer. However, when you connect to the Exchange server using Outlook, with mail delivery directed to your personal folders, unread mail will be moved into the Inbox of your personal folders instead of being stored in your Exchange server mailbox. Follow the appropriate instructions below to change this behavior:

Outlook 2002 or 2003

  1. From the Tools menu, select E-mail Accounts... .
  2. Select View or change existing email accounts, and then click Next.
  3. Next to "Deliver new email to the following location:", from the drop-down menu, select Mailbox - Your last name, Your first name. Click OK.

Outlook 97, 98, or 2000

  1. From the Tools menu, select Services... .
  2. Select the Delivery tab. Next to "Deliver new mail to the following location:", select Mailbox - Your last name, Your first name. Click OK.

To move messages already stored in personal folders back to the server mailbox, drag them from your personal folder to a folder in the mailbox. For more information, see the Knowledge Base document In Microsoft Outlook, how do I move one or more messages to another folder? If you cannot see the list of folders, from the View menu, select Folder List.

Note: If your personal folders are only on your home computer, you will have to use your home computer to do this.

After directing mail delivery to your Exchange server mailbox, you can still use your personal folders to permanently store or make copies of your email on your personal computer.

Recovering deleted messages

If you are looking for an email message that you deleted from your personal folders, you may be able to recover it from Outlook's deleted items retention area. For more information, see the following Knowledge Base document At IU, how can I recover deleted items in Outlook if I am an Exchange user?

Windows Vista features

My company had a customer inquire about getting a Windows Vista laptop and wanted particular features to be available. He wanted to make sure that the data on his pc would be secure even if it was lost or stolen. The first recommendation that I made was that he had a secure password on the pc which included upper case, lower case, a number and a symbol and that it be at a minimum of 7 characters. The second thing that I suggested was that he have a drive encryption which in Vista is Windows Bit Locker Drive Encryption and since he was not part of the Microsoft Software Assurance I recommended that he get the Ultimate edition as that is the only edition that offers the Drive Encryption. There were some other things that my company would do to insure the security of his pc but these built in features are a great starting point for security.

Do it right the first time! It's sometimes difficult to understand the importance of the initial investment in a computer network.

We’ve not gained a few new business opportunities recently due to companies lack of startup capital and our disinterest in helping them due to their lack of care about their systems. They decide that they just want to make things work but don’t understand the importance of the initial investment in their computer network or IT systems. As a business we are more successful because we choose not to work for pennies on the dollar like many other IT folk. We invest in qualifying our potential clients as much if not more then they invest in us. We’ve found a direct correlation between the increased longevity of the companies based on both amount of initial investment, and seriousness with which they heed our advice when it comes to engineering a secure and efficient computer network.

 

As you may know we are, “Do it right the first time” guys and we’ve put more expertise into securing and optimizing business networks for management ease and efficiency.  That way you don’t spend all day every day trying to fix the little annoying issues, can have peace of mind that you have the most professional network possible with the given resources, and that it will cost much less. The first month standard maintenance is free as well!

 

Other benefits include our vendor relationships, experienced and knowledgeable staff(not just one IT guy), instant remote support, discounted equipment and licenses, and now our new hosted VoIP service.

Mac's killing wireless

Mac users are reporting a number of problems with their wireless connections after updating to Leopard, according to traffic on Apple's support forums.

Users writing in a long thread — as of 3pm EDT it boasted more than 120 messages — described one issue as a steadily degrading wireless link from their upgraded Macs.

"When you connect to your wireless network, your transmit rate will be 54 (if you're using the 54g standard)," said someone identified as nunofgs. "If you start up a download or something that occupies your bandwidth (even LAN traffic), you will notice that the transmit rate drops to 11, then to 3, then to 1 until finally your downloads will drop, your iChat connections will fail and your browser will not load pages."

Numerous confirmations of the same symptoms were posted by other users. Among them was Gregory Sims. "I am having the same problem. After installing [Mac OS X] 10.5 my Power Mac G4 is very slow on the internet. The connection is worse than dial-up. I have never had this problem with 10.4 [Tiger]. My MacBook Pro is working fine, with a fast connection. I'm sorry to say 10.5 seems more like beta software than a US$129 upgrade. I hope this problem is fixed soon, or I will have to go back to 10.4."

Users suggested a variety of solutions, including applying the post-Leopard update Apple said fixes log-in issues as well as a vaguely-stated "connecting to some 802.11b/g wireless networks " problem. Other ideas ranged from finding and possibly removing the "AppleAirport2.kext" file to toggling IPv6 on/off.

Commonalities between users reporting the problem were difficult to define. Some, for instance, said they had used the "Upgrade" option to move to Leopard, while others said they had picked "Archive and Install" or even wiped their drives clean before installing Leopard from scratch.

Nearly all, however, made a plea similar to this by oxys: "Apple fix please Leopard is useless."

Although Apple hosts the support forums, the traffic is user-to-user only; company technical support personnel do not reveal themselves or offer advice

 

 

 

DocuPrep

Adding DocuPrep to a user on Terminal Server:

              From the C: drive copy the AC30 folder to the users profile, then open that folder and create a shortcut to the AC40.exe and place on the desktop. The Database is on the F: drive. DO NOT put the AC30 folder or shortcut on the All Users desktop as this will cause problems when more than one person tries to open it. If we want need to have all new users get the shortcut and the AC30 folder it should be put into the Default Users profile. All of this is per DocuPrep support
