Novell vs Server NT

Server NT brought forth a big improvement in prioritizing processes or threads in the multi-task environment. Managing multiple threads with control for asynchronous operations as well as synchronous operations across multiple CPU setups which is similar to any synchronous multi threading, was implemented..

Symmetric execution across threads and CPU devices improved performance, and the NTFS file system supported larger file names and storage devices. Early kernel mode partitioning supported DOS and OS/2 processes, and the capability of multiple 16 bit DOS processes. File sharing under Windowsfor Wmultiprocessing allows system and application requirements are distributed evenly among all available processors, making everything run much faster. Windows NT uses the NT File System (NTFS). This file system supports file names up to 256 characters. It also allows tracking of transactions. This means that if the system fails, NT returns the data to the state immediately before the crash. Microsoft designed Windows NT to make it portable. It consists of a kernel or nucleus, as well as various sub-systems. There subsystems available for applications that run programs based on OS / 2 and POSIX. A virtual DOS processor (DSP) running MS-DOS and Windows 16-bit applications. NT networking software includes point to point for NT users can share files with other users and applications running NT or Windows for Workgroups.

Windows NT NT security requires users to enter a password each time you start the operating system, whether or not connected to a servidor.Cada NT once it starts, it requests a password. NT government certification qualify for C-2 for safe environments. Microsoft has stated that in the future will offer enhancements that will increase the security level of NT and make it even more attractive to government agencies. A security feature is the NT User Manager. This program ensures that passwords be subject to company policy. It also allows each NT machine is configured to a number of users, giving each its own privilege level. It is also possible to create groups and give the same privileges to all members of a group. Another key safety feature is the event viewer. This program allows network administrators to view a log of all errors and breaches to the network, including time, date and type of violation, and the place where the event occurred and the name of the user involved. Implementation of NT with other network operating systems Windows NT Server provides integrated file sharing, printer sharing capabilities for workgroup computing and network interface open system, which includes integrated support for IPX / SPX, TCP / IP, NetBEUI and other transport.

NT Server is compatible with existing networks such as VINES, NetWare, UNIX, LAN Manager 2.x and Windows for Workgroups. Windows NT includes application programming interfaces (APIs) that allow manufacturers to network operating systems (NOS) write client software to enable their products to run with it. NT supports Macintosh clients and treats them the same way as users of the network, supporting the AppleTalk File Protocol.Macintosh users can access the server NT Server as if it were an AppleShare server. Windows NT Server 4.0 Integration of the user interface of Windows 95 NT 4.0, provides a consistent view across the desktop and the server, resulting in less training time and a faster development of the new network operating system. Tools such as Task Manager, and Network Monitor simplifies server administration.

The task manager offers extensive application and indications of CPU and graphics memory, which allows administrators to control system behavior.Network Monitor has the ability to monitor network traffic, allowing prevent performance problems with it. The directory service of Windows NT (NTDS) holds up to 25,000 users per domain, and hundreds or thousands per company. No matter how centralized or decentralized business, NTDS directory allows you to install an organization capable of providing a complete management of resources, services and applications. NTDS is a directory service that provides security, reliable architecture, graphical interface for management and open interoperability with Novell NetWare. NT 4.0 includes a diagnostic program that provides information about the drivers and the use of the network, minimizing the possible system errors.

This information is presented in graphical form that can be used from a remote NT system. The performance and scalability of the server have been improved as well as sharing and printing of files and performance of Internet server. Windows NT 4.0 works with systems such as NetWare, UNIX and IBM. It supports more than 5,000 hardware platforms and is compatible for most common network protocols such as TCP / IP, IPX / SPX, NetBEUI, AppleTalk, data link control (Data Link Control DLC), HTTP, network architecture systems (Systems Network Architecture, SNA), PPP and point to point protocol tunneling through (Point to Point Tunneling Protocol, PPTP). NT 4.0 is supported for a variety of client systems as Windows 3.x, Windows 95, Windows NT Workstation, IBM OS / 2 and Macintosh.

Vouch and Sway

The subject of auth in web applications is not trivial. Quickly you can learn that there are two disparate components, authentication and authority. If the web application is trivial, authority might be trivial, but authentication likely still is not.

Since we like to invent our own shorthand, we call these vouch and sway.

Vouch

The simplified term for authentication, vouch includes login and password, oauth, oauth2, 2fa or two factor authentication, time-based authentication, fingerprint, fob, facial, etc.

Sway

The simplified term for authority, this refers to the powers held by an authenticated user. In its simplest form, this might be a binary choice, user or admin.

Python Scaffolding SQL tables

Scaffolding support in a framework is a rapid means of implementing crud, i.e. a means of maintaining the database on which we will base our application

Crud is an acronym for Create, read, update and delete, operations that may need to be applied to rows in a table.

Scrudsie could be an acronym adding sorting, selecting, importing and exporting.

If we map out a database for an application, or we are looking to access data that already exists, and have come across dozens or hundreds of table formats, scaffolding is a means of coding crud functions for a table, or even for all tables, in just a few lines of code.

Scaffolding should occur within an Auth framework, especially a utility crud function where any table could have records added, deleted or modified.

Additionally, scaffolding could use a template that defines the entire DOM or identified DIV elements within a DOM (DOM definition wikipedia w3c)

DOM, in this context, stands for Document Object Model, and refers to all the html from the initial doctype definition tag through the final ending tag. Simply “view source” and the chaos of header, body, javascript, meta, link, css, divs, tables, lists and such things is very well known and defined

Python Crud with MySQL

Let’s do the same thing with MySql

pip install MySQL-python
import MySQLdb

class mydbconn():
    def __init__(self):
        self.con = MySQLdb.connect('x', 'x', 'x', 'x')

    def get_columns(self,table):
        cuc = self.con.cursor()
        cursData = cuc.execute("SHOW columns FROM " + table)
        HEADERS = cuc.fetchall()
        keyName = HEADERS[0][0]
        keyLen = self.lenFunction(HEADERS[0][1])
        return keyName, keyLen, HEADERS

    def lenFunction(self,varCharString):
        x = varCharString.find("(")
        varCharString = varCharString[x+1:]
        x = varCharString.find(")")
        varCharString = varCharString[:x]
        return int(varCharString)

if __name__=="__main__":
    con = mydbconn()
    keyName, keyLen, h = con.get_columns("customer")
    for i in h:
        print i

On the fifth line of the program, use your MySql credentials. Sometimes the first parameter is localhost, the second x is the username for the database, the password is third and the name of the database is fourth.

You also have to change the parameter in line 2 of the __main__ section to the name of the table you are using. This routine also has been used with databases that had a key other than named id for the first field, and it was important to have the name of the key and its length to proceed with scaffolding

In the Sqlite3 sqlalchemy example, we got a list of field names. In this example, we get a tuple of tuples. At this point, tuples might be a preferred format, they are immutable and hashable, and a utility crud function would not need to add and remove things from the tuple. However, in a more sophisticated scaffolding environment, you would add things like a field for password verification or especially remove things, like the ability to change certain fields.

Open Source ERP and CRM

The entire Linux operating system including source code can be downloaded from the internet.

In the open source world the most famous piece of software is Linux.  The entire Linux operating system including source code can be downloaded from the internet.  The Apache web server that is responsible for serving up a substantial amount of internet web pages is normally layered on top of the Linux operating system.

Apache may be available for Windows, kind of like Eva Gabor riding in the back of a 1948 Dodge pickup truck, and that may be where the average user most often interacts with the open source side of software.  A further note to understand in the open source software world is the notion in free as in open vs free as in beer.  If you get a free beer you do not have to pay for it, but open source software usually requires a costly agreement with the consultants and engineers that have the knowledge to work with the complex code in an open source application.

Open Source ERP is not a free software concept.  These complex business databases could in theory be used without the computer scientists and engineers that know their inner workings, but the costs of acquiring and maintaining the highly educated workers reqiuired to do this is greater than the cost of a service agreement.

In the Linux market, two examples of open source knowledge suppliers are Redhat and Novell.  Some may argue that other examples inclide Sun and IBM.

Zoho Invoice

Billing and Accounts Receivable, Cloud Invoice

For a small business, we a have just looked at Zoho Invoice. Zoho Invoice is a cloud based accounting system much like QuickBooks OnLine for small business invoicing. We are really impressed with the user interface. The initial sign up phase for a thirty day trial required e-mail verification, so it actually was several days ago that we first considered doing a review for Zoho accounting. But this morning, after digging through my e-mail for the verification links, we completed the process and began to evaluate the invoicing process for a simple time billing scenario such as a consultant would use.

First, we looked for a way to create an invoice. Zoho could not have made the link to begin creating an invoice any easier to pick out of the computer screen. This is a sharp contrast to QuickBooks which, even with it’s navigation screen, leaves us sometimes staring at all the things we can do and wondering where we went to do invoices.

Next, we know that there is really no such thing as an invoicing system without a customer file. And we had no customers entered into the system. Zoho could not have made this step easier. Just below the customer drop down box is a link to create a new customer. And upon adding a new customer, also a little easier than QB, was an option to save the customer and continue entering the invoice we had started.

Very smooth and intuitive, within three minutes, we had created an invoice for a customer, This left me wondering how I could e-mail and print the invoice. With a little glancing around, on the right side of the screen are options to email and print the invoice. Viola!

Having consulted for dozens of companies for 25 years, I wish I had this resource years ago. We will have more information on Zoho invoicing and accounts receivable coming up.

Lean Manufacturing and Web design

Lean manufacturing zealots have declared that web-site design and development can be done faster with the help of Lean manufacturing techniques. They contend that even copywriting is faster, don’t ask us how. Lean manufacturing is a promising practice in the delivery of goods that eliminates pointless and wasteful elements of the production and delivery cycle for elimination. Somehow, this is done by hiring wasteful and self absorbed Lean Manufacturing consultants, because you were too stupid to do this. But let’s examine the Lean Manufacturing premises and promises to see if we can just apply some common sense to our operation. We can even ponder the creative process of copy-writing and look for an application for these principles.

First, widely we hear claims for Lean, these I will call the promises;

  • 1/2 the man hours
  • 1/2 the defects (quality improvements )
  • 1/3 the engineering man hours
  • 1/2 the floor space for the same factory/distribution productivity
  • 1/10th or less of in-process inventories, i.e. Just in Time or JIT WIP management

To back up these goals, the Lean evangelists ask us to envision a ‘fictitious Boat Factory.’ In their workshop they ask teams to for a production line to make as many cardboard sailboats as possible in 30 minutes. They say that the workers struggled to produce 20 good boats and produced 30 defective boats. They then reorganize the divisions of labor in an improved manner to help the team produce 36 boats with only one defective. They hope their dupes miss the point that the initial crappy production line was designed to be unwieldy by the creators of the workshop. They instead only stress the results.

  • 80% output improvement
  • 70% reduction in lead time
  • 97% reduction in defects

All because the assigned method forming the assembly line was optimized. Their assumption is that manufacturers are too stupid to do this, and their data is whatever they say. This is not to say that a production line exists that cannot be improved. My only point is that this little workshop and its purported lessons are rather pedantic.

The relevant facts of Lean Manufacturing consist of looking at the production line in terms of bottlenecks, length, capacity and people. They squeeze those terms into the word FLOW by calling this Faults, Length, opening and workforce. I think they wasted a lot of time doing that. My first suggestion for the Lean Manufacturing people is to quit wasting their time on silly acronyms and stick to the point. A line consists of capacity and operations, and is never perfect. Wow, C-O-NP. Whatever. One claim of the Lean Manufacturing people is that Toyota has seven to ten times the productivity of American companies. Any experienced manufacturing professional knows the utilization of KanBan by Toyota, which can help any manufacturer improve throughput at the expense of WIP. Not surprisingly, when you optimize one thing, something else has to be loosened up to accommodate.

No better example of Lean Manufacturing in practice would be the delivery of water to a fire. Dozens of firemen may spend hours and days idly at the firehouse, and then when called upon all traffic on the road should yield to the firetrucks. Sacrifices made in the productivity in some areas to get water on a fire most quickly.

But even more fascinating is the application of this cheerleader driven logic excercize to web design

The Lean people start with the word FLOW. F stands for faults, and they assume first that clients know what they want. In the Lean Manufacturing model of ideal web-design they encourage lots of meetings to determine the exact number of pages and design of the web-site required. Those meetings of course, are roughly a waste of 75 to 90 percent of meeting time. The purpose of a website is to present information, via the internet and search engines, to an audience of information consumers. Some meetings are required but for the most part only delay the publishing of the website to the internet and search engines. But never mind that, isn’t it just extraordinary how they work the word FLOW into things. At Web-Atlanta we have published web-sites with copywriting in 72 hours. Atlanta web design doesn’t get leaner than that.

At Web-Atlanta, one difficulty we do have is with the graphics department. They insist that a certain amount of ping-pong, fuse-ball and fresh fruit juice are components of a happy workforce. In our copy-writing department, I can assure you that a whip and a cattle prod are quite sufficient. Seriously, the rapid publishing affords us interaction with our clients supplementing the design. The budget is not spent on a myriad of wasteful workshops cutting out cardboard boats with blunt scissors, the real interaction begins when the prototype hits the clients desk and conference calls begin with the clients and Atlanta web design.

The next letter is L, and as you can see, Atlanta web design from Web Atlanta can bring forth a published web site before ten percent of the scheduled meetings have occurred for other web design firms. Then we come to the letter ‘O’ which pertains to the capacity to produce web-sites. Not including graphics, Atlanta web design firm Web-Atlanta produces three sites per day, technically and in copy-writing. In business for fifteen years, we are still waiting for the graphics arts department to decide on the logo for our stationary.

Web Atlanta is a great advocate of incorporating existing EPS graphics into the web design. If you have a public relations graphics package then we can save countless weeks of waiting by allowing our graphics arts department to just play fuse-ball and drink juice while they think about our Logo at Web-Atlanta – our technical department can do the manipulations required to use your existing graphics.

The Lean Manufacturing folks would be a little peeved if I finished without mentioning the W in the word FLOW. As I have mentioned, our use of cattle prods and corporal punishment is all we need to mention in dealing with our technical and copy-writing departments. But another invention of the Lean Manufacturing world are the 5 esses.

  • remove clutter
  • Organize
  • maintain
  • organize
  • measure

Yes, those are the five esses of Lean Manufacturing. Ess means the letter ‘S’ and they make one thing into two because a number 5 looks like a letter ‘S’. Wonder how much time they wasted on that? Don’t waste your time wondering – too much.

At Web Atlanta website design firm, tools that help us quickly produce a website also optimize Page Load Time. It is widely accepted that fast-loading pages improve the user experience. In recent years, many sites have started using AJAX techniques to present the user with the webpage before having to wait for every element of a complex page to load. However the majority of the page load time is spent in separate HTTP requests for images, JavaScript, and style-sheets. Speeding up these separate HTTP requests might help, and the Rails world has shown examples of this form of optimization.

With the roll out of HTML5 and the cacheing technologies in practice at Web Atlanta website design the delays in serving webpages is kept to a minumum. While we typically avoid a rails application for mundane web design, we respect the slip-streaming cleverly developed for massive css and js library delivery while keeping the number of http requests to a reasonable level. With more then nine out of ten internet users connected assymetrically, i.e. their download speed is much higher than upload, interruptions for http requests should be carefully considered, even when AJAX may seem sexy. It is simplistic to assume that bandwidth is rapidly expanding when in fact some users still may even use dial-up or share with many users a slower T1 or T1 speed DSL connection.  If you conditionally gzip HTML, javascript, or CSS, you probably want to add a “Cache-Control: private” if you set an Expires header. This will prevent problems with caching by proxies that won’t understand that your gzipped content can’t be served to everyone. (The Vary header was designed to do this more elegantly, but you can’t use it because of IE brokenness.) For anything where you always serve the exact same content when given the same URL (e.g. static images), add “Cache-Control: public” to give proxies explicit permission to cache the result and serve it to different users. If a caching proxy local to the user has the content, it is likely to have much less latency than you On pages where your users are often sent the exact same content over and over, such as your home page or RSS feeds, implementing conditional GETs can substantially improve response time and save server load and bandwidth in cases where the page hasn’t changed. The idea is pretty simple: When you generate a page, you give the browser a little extra information about exactly what was on the page you sent. When the browser asks for the same page again, it gives you this information back. If it matches what you were going to send, you know that the browser already has a copy and send a much smaller 304 (Not Modified) reply instead of the contents of the page again. And if you are clever about what information you include in an ETag, you can usually skip the most expensive database queries that would’ve gone into generating the page.

Load times for five style sheets of 10kb can be more than double that of one stylesheet of 50kb. Thus, the railsish optimizations can double the speed of RoR webpage delivery. Many designers are afraid that cached webpages may lead to content served but not statistically captured. In the GA model though, the use of an asynchronous JS client side seems to insure that each client reports each web page at least exactly once per cookie-life. However, in distributed content environmnets the server managers such as Amazon and Yahoo suggest that if your files have changed, use a new file name. You can trick browsers into thinking the file URL has changed by adding a useless query string, e.g. index.php?moonjuice=fryed-okra.
