IN THE HIGH COURT OF JHARKHAND AT RANCHI Cr.M.P No. 242 of 2014 ....
Ayub Raza ..... .... Petitioner Versus The State of Jharkhand ..... .... Opposite Party
CORAM: HON'BLE MR. JUSTICE RONGON MUKHOPADHYAY For the Petitioner : Mr. Arshad Hussain, Advocate Mr. Haider Ali, Advocate For the State : Mr. Pankaj Kumar, A.P.P.
....
04/ Dated 10th December, 2014 I.A No. 6239 of 2014 This application has been filed for amendment/ addition of the reliefs sought by the petitioner.
On going through the application and after careful perusal of the interlocutory application the same is allowed.
I.A No. 6239 of 2014 is disposed of. The averments made in para-5 of the I.A shall form part of the main quashing application.
Cr.M.P No. 242 of 2013 Heard learned counsel for the petitioner and learned counsel for the State.
In this application the prayer of the petitioner is for quashing the entire criminal proceedings including the first information report which had been instituted in connection with Kara P.S.Case No. 72 of 2013 corresponding to G.R Case No. 459 of 2013 registered for the offences punishable under Sections 379 and 411 of the Indian Penal Code, Section 4(i) of the Mines and Minerals (Development and Regulation) Act, 1957 and Section 21 of the Air (Prevention and Control of Pollution) Act, 1981.
The prosecution story in brief is that the informant who is the Assistant Sub-Inspector of police was on petrolling duty in the evening of 19.12.2013 observed that a Turbo Truck bearing Registration No.JH01AR-6412 was passing by at a high speed. It was also alleged therein that the said truck was apprehended and on inspection it was found loaded with sand but no valid papers were produced by the driver with respect to the sand loaded on the truck.
After investigation the case having been found to be true, charge-sheet was submitted pursuant to which cognizance for the offences punishable under Sections 379/411 of the Indian Penal Code, Section 4(i) of the Mines and Minerals (Development and Regulation) Act, 1957 and Section 21 of the Air (Prevention and Control of 2 Pollution)Act, 1981 was taken vide order dated 5.8.2014.
Learned counsel for the petitioner submits that he is the owner of the vehicle and since the vehicle was under the custody of driver, the owner cannot be directly made responsible for the offence as has been alleged in the first information report. Learned counsel for the petitioner has further submitted that institution of the criminal case and taking cognizance subsequent thereto is bad in law in view of the fact that Assistant Sub-Inspector of police is not empowered to institute the first information report under the provisions of the Mines and Minerals (Development and Regulation) Act, 1957 or under the provisions of the Air (Prevention and Control of Pollution) Act, 1981.
In this context, he has referred to a judgment of the Hon'ble Supreme Court in the case of State (NCT of Delhi) vs. Sanjay [(2014) 9SCC 772] in which the Hon'ble Supreme Court while considering the question as to whether the provisions contained in Sections 21, 22 and other sections of the Mines and Minerals (Development and Regulation) Act, 1957 operate as a bar against the prosecution of a person who has been charged with allegations which constitutes offences under Sections 379/411 of the Indian Penal code and that in the light of the relevant provisions of the MMDR Act, vis a vis the Code of Criminal Procedure and the Indian Penal Code had held that the ingredients constituting the offence under the MMDR Act and the ingredients of dishonestly removing sand and gravel from the riverbed without sand which is the property of State is a distinct offence under the Indian Penal Code. It was further held therein that for the commission of the offence under Section 378 of the Indian Penal Code, on receipt of the police report, the magistrate having jurisdiction can take cognizance of the said offence without awaiting the receipt of the complaint that may be filed by the authorised officer for taking cognizance in respect of violation of various provisions of the MMDR Act. Relevant paragraphs of the above noted judgment is quoted herein under:-
"68. In State of U.P. v. Babu Ram Upadhya, while interpreting a particular statue as mandatory or directory this court observed: (AIR p. 765 para 29) "29. ... When a statute uses the word 'shall', 'prima facie', it is mandatory, but the court may ascertain the real intention of the legislature by carefully attending to the whole scope of the statute. For ascertaining the real intention of the 3 legislature the court may consider, inter alia, the nature and the design of the statute, and the consequences which would follow from construing it the one way or the other, the impact of other provisions whereby the necessity of complying with the provisions in question is avoided, the circumstance, namely, that the statute provides for a contingency of the non-compliance with the provisions, the fact that the non- compliance with the provisions is or is not visited by some penalty, the serious or trivial consequences that flow therefrom, and, above, all, whether the object of the legislation will be defeated or furthered."
69. Considering the principles of interpretation and the wordings used in Section 22, in our considered opinion, the provision is not a complete and absolute bar for taking action by the police for illegal and dishonestly committing theft of minerals including sand from the riverbed. The Court shall take judicial notice of the fact that over the years rivers in India have been affected by the alarming rate of unrestricted sand mining which is damaging the ecosystem of the rivers and safety of bridges. It also weakens riverbeds, fish breeding and destroys the natural habitat of many organisms. If these illegal activities are not stopped by the State and the police authorities of the State, it will cause serious repercussions as mentioned hereinabove. It will not only change the river hydrology but also will deplete the ground water levels.
70. There cannot be any dispute with regard to restrictions imposed under the MMDR Act and remedy provided therein. In any case, where there is a mining activity by any person in contravention of the provisions of Section 4 and other sections of the Act, the officer empowered 4 and authorised under the Act shall exercise all the powers including making a complaint before the Jurisdictional Magistrate. It is also not in dispute that the Magistrate shall in such cases take cognizance on the basis of the complaint filed before it by a duly authorised officer. In case of breach and violation of Section 4 and other provisions of the Act, the police officer cannot insist the Magistrate for taking alleging contravention of the said Act. In other words, the prohibition contained in Section 22 of the Act against prosecution of a person except on a complaint made by the officer is attracted only when such person is sought to be prosecuted for contravention of Section 4 of the Act and not for any act or omission which constitutes an offence under the Penal Code.
71. However, there may be a situation where a person without any lease or licence or any authority enters into river and extracts sand, gravel and other minerals and remove or transport those minerals in a clandestine manner with an intent to remove dishonestly those minerals from the possession of the State, is liable to be punished for committing such offence under Sections 378 and 379 of the Penal Code." Learned counsel for the State on the other hand, submits that so far as cognizance with respect to the provisions under MMDR Act is concerned, the same has been addressed in the judgment rendered by the Hon'ble Supreme Court as referred to above. He further submits while relying on the aforesaid judgment with respect to the offences punishable under Sections 379 and 411 of the Indian Penal Code that, the police does have the power to investigate the case under the provisions of the Indian Penal Code and that the learned Magistrate is empowered to take cognizance and, therefore, the order dated 5.8.2014 by which cognizance was also taken for the offences punishable under Section 379/411 of the Indian Penal Code does not suffer from any infirmity.
Section 22 of the Mines and Minerals (Development and Regulation) Act, 1957 reads as follows:-
5"22. Cognizance of offences.- No court shall take cognizance of any offence punishable under this Act or any rules made thereunder except upon complaint in writing made by a person authorised in this behalf by the Central government or the State Government."
It would appear from a plain reading of Section 22 of the MMDR Act as quoted above is that the court is precluded from taking cognizance of any offence punishable under the Act except upon a complaint made in writing by a person authorized in this behalf by the Central Government or the State Government.
Section 2(d) of the Criminal Procedure defines a complaint which reads as follow:-
" 2 (d) " complaint' means any allegation made orally or in writing to a Magistrate, with a view to his taking action under this Code, that some person, whether known or unknown, has committed an offence, but does not include a police report".
A conjoint reading of section 22 of the MMDR Act and Section 2(d) of the Criminal procedure, 1973 would mean that no first information report can be instituted for the offences under the Mines and Minerals (Development and Regulation) Act, 1957 "as the definition of a complaint in Section 2 (d) of Code of Criminal Procedure excludes a police report".
In such circumstances the Assistant Sub-Inspector of police who had instituted the first information report for the offences punishable under Section 4(i) of the MMDR Act did not have the jurisdiction to institute such FIR and, therefore, the learned Judicial Magistrate, 1 st Class committed an error of law while passing the order taking cognizance dated 5.8.2014 so far as section 4(i) of the MMDR Act is concerned.
As regards the cognizance by the learned Judicial Magistrate Ist Class with respect to Section 21 of the Air ( Prevention and Control of Pollution) Act, 1981 it would be necessary to quote Section 43 of the Act which reads as follow:-
[43. Cognizance of offences.- (1) No court shall take cognizance of any offence under this Act except on a complaint made by-
( a) a Board or any officer authorised in this behalf by it; or
(b) any person who has given notice of not less than sixty days, in the manner prescribed, of the alleged offence and of his intention to make a complaint to the Board or officer 6 authorised as aforesaid, and no court inferior to that of a Metropolitan Magistrate or a Judicial Magistrate of the first class shall try any offence punishable under this Act. (2) Where a complaint has been made under clause(b) of sub-section (1), the Board shall, on demand by such person, make available the relevant reports in its possession to that person.
Provided that the Board may refuse to make any such report available to such person if the same is, in its opinion, against the public interest.]".
From a perusal of section 43 Air (Prevention and Control of Pollution) Act, 1981 the same reveals that no court shall take cognizance except on complaint made by a Board or any officer authorised in this behalf or any person who is given a prior notice of not less than 60 days in the manner prescribed of his intention to make a complaint to the Board or officer authorised as aforesaid.
The record does not disclose of any prior notice in the prescribed manner given to the board or any officer authorised so as to institute the case and no document with respect to above has been brought to the knowledge of the Court. The language of Section 43 of the Air (Prevention and Control of Pollution)Act, 1981 also speaks about a complaint and not a first information report and, therefore, considering the fact that necessary ingredients for the purposes of fulfillment of requirements under Section 43 of the Air (Prevent and Control of Pollution) Act, 1981 have not been fulfilled, the prosecution of the petitioner under Section 21 of the Air ( Prevention and Control of Pollution) Act, 1981 can also not be allowed to continue.
Considering the totality of the facts and circumstances enumerated above the order dated 5.8 2014 by which cognizance was taken by the learned Magistrate for the offence under Section 4(i) of the MMDR Act, 1957 and section 21 of the Air (Prevention and Control of Pollution Act, 1981 is hereby quashed. The order taking cognizance for the offence punishable under Sections 379/411 of the Indian Penal Code on the basis of the discussions made above does not warrant any interference and the trial with respect to the said offences shall proceed accordingly.
This application is allowed in the manner indicated above.

CSS supports color names, hexadecimal and RGB colors.
In addition, CSS3 also introduces:
The numbers in the table specify the first browser version that fully supports CSS3 color values/property.
| Property | |||||
|---|---|---|---|---|---|
| RGBA, HSL, and HSLA | 4.0 | 9.0 | 3.0 | 3.1 | 10.1 |
| opacity | 4.0 | 9.0 | 2.0 | 3.1 | 10.1 |
RGBA color values are an extension of RGB color values with an alpha channel - which specifies the opacity for a color.
An RGBA color value is specified with: rgba(red, green, blue, alpha). The alpha parameter is a number between 0.0 (fully transparent) and 1.0 (fully opaque).
The following example defines different RGBA colors:
#p1 {background-color: rgba(255, 0, 0, 0.3);} /* red with opacity */
#p2 {background-color: rgba(0, 255, 0, 0.3);} /* green with opacity */
#p3 {background-color: rgba(0, 0, 255, 0.3);} /* blue with opacity */
HSL stands for Hue, Saturation and Lightness.
An HSL color value is specified with: hsl(hue, saturation, lightness).
The following example defines different HSL colors:
#p1 {background-color: hsl(120, 100%, 50%);} /* green */
#p2 {background-color: hsl(120, 100%, 75%);} /* light green */
#p3 {background-color: hsl(120, 100%, 25%);} /* dark green */
#p4 {background-color: hsl(120, 60%, 70%);} /* pastel green */
HSLA color values are an extension of HSL color values with an alpha channel - which specifies the opacity for a color.
An HSLA color value is specified with: hsla(hue, saturation, lightness, alpha), where the alpha parameter defines the opacity. The alpha parameter is a number between 0.0 (fully transparent) and 1.0 (fully opaque).
The following example defines different HSLA colors:
#p1 {background-color: hsla(120, 100%, 50%, 0.3);} /* green with opacity */
#p2 {background-color: hsla(120, 100%, 75%, 0.3);} /* light green with opacity */
#p3 {background-color: hsla(120, 100%, 25%, 0.3);} /* dark green with opacity */
#p4 {background-color: hsla(120, 60%, 70%, 0.3);} /* pastel green with opacity */
The CSS3 opacity property sets the opacity for a specified RGB value.
The opacity property value must be a number between 0.0 (fully transparent) and 1.0 (fully opaque).
Notice that the text above will also be opaque.
The following example shows different RGB values with opacity:
#p1 {background-color:rgb(255,0,0);opacity:0.6;} /* red with opacity */
#p2 {background-color:rgb(0,255,0);opacity:0.6;} /* green with opacity */
#p3 {background-color:rgb(0,0,255);opacity:0.6;} /* blue with opacity */

My copy of iLife 2005 came yesterday. I quickly installed it to see all the wondrous improvements since the original version of iPhoto/iMovie that came with my power book in 2002. The motivating factor behind spending the $79.00 for iLife '05 was the updated iPhoto and iDVD. iLife also comes with GarageBand and iMovie.
It took over an hour for iLife to import my iPhoto library. I have 1,756 photos in my library. However, once the import was complete, I found the new iPhoto to be a lot faster. I haven't yet played with iPhoto's advanced features, but will take a closer look the next time I import pictures from my digital camera. iPhoto is only the first stop in my photo archive workflow. Everything lives in my web-based photo-album, powered by Gallery. I use iPhoto to get pictures from my digital devices and touch them up before importing into Gallery. I use the iPhotoToGallery export plugin to upload the pictures into Gallery. (I wish there were some way to sync. gallery with iPhoto.) I like iPhoto's new keyword feature, but I'm dissappointed it still only supports one library of photos and does not support sub-albums. iDVD did not install by default because I don't have a super drive. I have a Lacie DVD writer which Roxio Toast identifies as a "Pioneer DVD-RW DVR-106D." I believe this is the same model as the super drive. Even if it isn't, iDVD now supports writing a DVD image which I can then burn using Toast. The CaptyDVD software that came with the Lacie drive is pretty basic. It will still take nearly 24 hours to encode a DVD using my little 800 MHz powerbook! I still have 60+ Gig of digital video from our wedding TWO years ago that needs to be compiled and burned to DVD. When I get motivated to actually do this, iLife will help.- A RAW Look at iPhoto 5
- Output Like a Pro with iPhoto 5
- iPhoto Library Manager - allows switching between multiple iPhoto libraries

Gary Neville tells Man Utd they need "five or six signings" in January transfer window
Manchester United boss Ole Gunnar Solskjaer has been warned by club legend Gary Neville he needs several new additions in the transfer window to strengthen his struggling side
by Rich Jones, https://www.mirror.co.uk/authors/rich-jones/Manchester United have been told they need "five or six signings" to turn things around in January by former player Gary Neville.
Neville watched on in frustration in his role as co-commentator on Sky Sports as United drew 3-3 with Sheffield United in a frantic Bramall Lane encounter on Sunday.
Ole Gunnar Solskjaer's side came from 2-0 down to take a 3-2 lead only to concede a late equaliser, leaving them ninth in the Premier League table.
And he outlined the need for a number of signings in order to strengthen their side to a sufficient level to climb up the table - pinpointing three specific positions which need urgent attention.
“They need a striker, they need two midfield players, they need a left-back – they need five or six signings," Neville said.
“They can’t do that until January and obviously the summer but the midfield will not go away as a problem for Manchester United just because of an injury.
“It’s a problem full stop – it needs strengthening.”
Whilst Neville sees improvement needed in plenty of areas, he highlighted central midfield as the biggest cause for concern.
“The midfield’s just a problem for United full stop, let’s be clear about it,” he said.
“Even with Scott McTominay in it’s a problem. They haven’t strengthened in that area, obviously Pogba’s injured.
“It’s a problem for them and it’s just not good enough, the midfield just doesn’t have good enough quality.”
Injuries have played a part, but Fred and Andreas Pereira have struggled to make an impact as stand-ins for McTominay and Pogba.
A host of players have been linked with the Red Devils in January, including midfielders such as Sean Longstaff, Declan Rice, James Maddison, Nicolo Zaniolo and Eduardo Camavinga amongst others.
Strikers including Erling Braut Haaland, Mario Mandzukic, Moussa Dembele and Timo Werner have also been linked ahead of their latest transfer window.


Preparation time
less than 30 mins
Cooking time
10 to 30 mins
Serves
Serves 2
Heat a large saucepan of lightly salted water until boiling for the pasta.
Meanwhile, heat half the butter with the oil in a frying pan until no longer foaming and feeling hot.
Add the liver and fry for 1-2 minutes on each side until well browned and just firm when pressed with the back of a fork.
Season in the pan, then remove to a warmed plate and keep warm.
Add the port or Madeira to the pan, bring to the boil and allow to bubble until reduced by half.
Add the vinegar and cook for a few seconds.
Pour in the stock and bring to the boil, stirring. Continue to boil until reduced by half.
Meanwhile, add the pasta to the pan of boiling water and cook for 2-3 minutes for fresh pasta or according to the packet instructions for dried pasta until just tender.
Drain, then toss with the remaining butter and the fresh or dried sage.
Season the pasta well and divide between two warmed serving plates.
Lay the liver over the top (you may want to slice this first).
Whisk the crème fraîche into the sauce in the pan, if using. Check the seasoning and spoon over the liver. Serve immediately

evothings. eddystone
Source: evothings-libraries/
Library for Eddystone beacons.
It is safe practise to call function evothings.scriptsLoaded to ensure dependent libraries are loaded before calling functions in this library.
Methods
Abstract types
Methods
calculateAccuracy(txPower, rssi)
Calculate the accuracy (distance in meters) of the beacon.
The beacon distance calculation uses txPower at 1 meters, but the Eddystone protocol reports the value at 0 meters. 41dBm is the signal loss that occurs over 1 meter, this value is subtracted by default from the reported txPower. You can tune the calculation by adding or subtracting to param txPower.
Note that the returned distance value is not accurate, and that it fluctuates over time. Sampling/filtering over time is recommended to obtain a stable value.
Example
// Note that beacon.txPower and beacon.rssi many be undefined,
// in which case calculateAccuracy returns null. This happens
// before txPower and rssi have been reported by the beacon.
var distance = evothings.eddystone.calculateAccuracy(
beacon.txPower, beacon.rssi);
Parameters
| Name | Type | Optional | Description |
|---|---|---|---|
|
txPower |
|
|
The txPower of the beacon. |
|
rssi |
|
|
The RSSI of the beacon, subtract or add to this value to tune the dBm strength. 41dBm is subtracted from this value in the distance algorithm used by calculateAccuracy. |
- Returns
-
Distance in meters, or null if unable to compute distance (occurs for example when txPower or rssi is undefined).
createLowPassFilter(cutOff)
Create a low-pass filter.
Example
// Create filter with cut off 0.8
var lowpass = evothings.eddystone.createLowPassFilter(0.8)
// Filter value (returns current filter value)
distance = lowpass.filter(distance)
// Get current value
distance = lowpass.value()
Parameter
| Name | Type | Optional | Description |
|---|---|---|---|
|
cutOff |
|
|
The filter cut off value. |
- Returns
-
Object with two functions: filter(value), value()

objects, which represent one of the ETF constituents. ETFConstituentsData
objects have the following attributes:
public class ETFConstituentsAlgorithm : QCAlgorithm { public override void Initialize() { var universe = Universe.ETF("SPY", Market.USA, UniverseSettings, ETFConstituentsFilter); AddUniverse(universe); } private IEnumerable<Symbol> ETFConstituentsFilter(IEnumerable<ETFConstituentData> constituents) { // Get the 10 securities with the largest weight in the index return constituents.OrderByDescending(c => c.Weight).Take(10).Select(c => c.Symbol); } }
class ETFConstituentsAlgorithm(QCAlgorithm): def Initialize(self) -> None: universe = self.Universe.ETF("SPY", Market.USA, self.UniverseSettings, self.ETFConstituentsFilter) self.AddUniverse(universe) def ETFConstituentsFilter(self, constituents: List[ETFConstituentData]) -> List[Symbol]: # Get the 10 securities with the largest weight in the index selected = sorted([c for c in constituents if c.Weight], key=lambda c: c.Weight, reverse=True)[:10] return [c.Symbol for c in selected]

Rails, we've loved it since it was a wee babe of v0.8 versions old! Server-side Javascript since it was called Livewire. And the web since it replaced Archie and Veronica.
We like data. And we're not afraid of marketing. Or math. Let us help with the collection, analysis, and visualization of your data.
We've built a lot of software for a lot of people. Let us help you and your team keep up with the best practices of testing, deployment, and the craft of software development.
Starting with a tiny staff, some seed money from a wealthy and mysterious benefactor, and the best intentions, Transitionpoint was born during the startup explosion of 2000. Based in beautiful and historic downtown Charlottesvile, Virginia, we solved problems for large game companies, small local businesses, famous universities, and enthusiastic entrepreneurs. We used ColdFusion and Java, usually hosted on our own Cobalt servers.
A move across the mountain to Harrisonburg, Virginia, and new opportunities and challenges pushed our fledgling company out of the nest and on a solo journey for John Paul.
After spending time moving between home and coffee shops, it was time to get a real office. Transitionpoint becomes a partner in Thurston Enterprises and builds out over 3000 square feet of downtown office space overlooking our courthouse square. Located above a building housing a coffee shop, a beer and wine store, and brewpub, we couldn't be happier about our new digs!
After years of building web applications with ColdFusion, we fell in love with Rails, eloped, and have been happy ever since. After a chance dinner date with DHH and Dave Thomas at OSCON the night before the release of the first edition of the AWDR book we tried it out and things have never been the same.
A startup project led to an extended residency in New York where we became and continue to be part of the NYC tech scene. As our Amtrak miles and frequent stay points rack up, we've helped numerous startups with the initial products, sites, and scaling.
I joined General Assembly as their second developer and soon thereafter built and managed their remote development team that spanned from the UK to the West Coast. I was an advisor to the curriculum of our first bootcamp and then ran the team that built our first video training product, Front Row.
Continuing on the path of working in online tech education, I joined friends at Treehouse where I soon became the developer for the marketing team where experimentation and data analytics were key parts of daily work. Eventually my position morphed into their first data engineer.
Looking to make a bigger impact, I cofounded Wheelhouse.io to build interactive, developer-focused training tools. Backed by a seed round including Jason Calcanis, and part of the first cohort at the Grand Central Technology Accelerator, we partnered with GitHub and Docker to deliver innovative, interactive training used by over 20,000 people in our first year.
Yet more edtech work -- this time for a team that focuses on technology at all levels, from K12 through college and beyond. As an architect, I worked on our (micro)services migration, our new React front-end, and a company-wide effort to ovehaul our entire marketing approach and related analytics.
After a decade away from working with healthcare companies, it was time to explore it again. This time, it was all about iPad-based check-in software and integration with EMR systems through a public API. As is becoming a pattern, I built our first real data "warehouse", create a small data analytics team over the summer with some excellent interns, and learned a *lot* about HIPPA.
We still love working with enthusiastic entrepreneurs and organizations of all sizes with a strong interest in the healthcare, education, and non-profit sectors. We still focus on Ruby on Rails and have extended our capabilities into marketing analytics, data science, and building/mentoring remote developers and teams. We are still in the Shenandoah Valley, still in our lovely office space, and still love the excitement of the startup world.
Founder, CTO
We work really well with others and have good relationships with a wide range of top-quality developers in the US, Latin America, and Europe.

--- layout: post title: "Managing VFP Class Libraries" author: "Steven Black" type: "" header_text: "" lead_text: "" excerpt: "" category: tags: [] ---
The more applications you develop, and the bigger the teams that work on them, and the more often the software is revised, the more class library management skills are important. Face it: you can't ship a large application without good class management. as program size increases, proper structure becomes exponentially more important. this session, for advanced visual foxpro developers, is all about being an effective class librarian, and working smart with visual and code class libraries. we'll also talk about the conceptual and physical management of classes and class libraries, how the VFP Class Browser and Component Gallery play complementary roles in class library management, and how library structures are related to component architecture. Time permitting, we'll also look at tools to aid in library engineering, documentation, information dissemination, and tactics for version control.
I'm writing this document to share some sensible practices for dealing with VFP Class Libraries. Be aware that if you work alone, or if you are working on a small project, what I suggest herein matters much less than if you are developing a larger system, and collaborating with several other developers. That's because experience suggests that the complexity of managing Visual FoxPro classes and class libraries varies with the size of the project, the intensity of development activities, the complexity of the project's class design, and on the number of developers involved.
Like the old saying goes, to build a 1-meter high tower, all you need is a few undamaged beer cans. But to build a 10-meter or 100-meter high tower, you need a plan, and you need to pay attention to process and structure. That's what this paper is about: how to structure your class libraries so they can scale, at least a little bit.
So, without further ado
Major Rule: Use your own classes as the basis for the controls in your applications.
Figure 1 illustrates a class hierarchy spawned directly from a VFP base class. This is a classic rookie mistake. The problem here is this hierarchy culminates with a read-only class, a Visual FoxPro built-in base class. To make a global change to the hierarchy you'll need change all the first-level subclasses since the culmination class is read-only, so many of the so-called benefits from using an inheritance hierarchy are largely lost.
Figure 1. A class hierarchy spawned directly from a VFP base class.
Compare Figure 1 with Figure 2, which shows a class hierarchy wherein the classes culminate with a class of your own making. To make a global change to the hierarchy you can make a change to the culmination class (class _Textbox, in Figure 2) and, as long as the subclasses are properly implemented, they will inherit its changes.
Figure 2. A class hierarchy spawned from your own base class.
Using your own base classes between your operational classes and the VFP read-only base classes gives a buffer between your classes and the VFP base classes, protecting the class against changes in VFP base class behavior. It also gives you a way to integrate your own standards into the roots of all your classes.
Minor Rule: Use insulation classes to protect you from version changes.
Arguably the classes provided by third parties should be considered de-facto read-only, even if you possess the source code. Third party classes can be unpredictably volatile. If you make code changes to original third-party sources, you have a problem: how do you reliably integrate your changes in the event of new versions? Moreover consider the parallel problem of how to manage both enterprise-wide and application-specific alterations, and not touch this third-party source.
Insulation layers (Figure 3), sometimes colloquially known as I-Layers, are an artificial culmination point that allow centralized access to framework and other volatile subclassable structures. Reading upwards in figure 3, application-specific classes can vary from project to project, and the insulation layer can normally serve simultaneously as an enterprise feature layer and as a framework isolation layer.
Figure 3. Insulation layers protect you from framework changes at the price of an extra inheritance layer.
Insulation layers are not without obvious expenses. Foremostly they add layers to your class hierarchies, which makes things like debugging more tedious.
If you create software for multiple client, consider creating a layer for each company. This only makes sense in the case where a software company will be working repeatedly for a group of customers. The basic structure is a follows:
VFP base classes
Your VFP insulation layer
Customer 1 classes
Application 1 classes
Application 2 classes
Customer 2 classes
Application 3 classes
Application 4 classes
So an insulation layer is a good architectural idea that comes at the cost of slightly deeper hierarchies. Now, if you're following along, you see that we soon have all these classes in all these layers! How best to deal with them?
Good Practice: Know the VFP Class Browser and Component Gallery, and understand what each does best.
A class library is a physical package of classes. For managing visual class libraries (VCXes) you use the Class Browser. But classes can -- and should -- be abstracted in a variety of other ways. For this we can use the Component Gallery, to organize them, be they VCXes or PRGs, along with all the other elements of our software. The Component Gallery is great for creating virtual and abstract groupings of related items in a way that personally suits a particular situation.
Separate white papers on using the Class Browser and Component Gallery are available for download from http://www.msdn.microsoft.com/vfoxpro.
Good Practice: Use Ken Levy's superclass tool; it lets you see exactly what your inheriting.
The deeper your class hierarchies, the more you'll appreciate tools like SuperCls.PRG, which now ships with Visual FoxPro. Supercls gives you the ability to see and edit superclass code while working in the class designer's code editing windows.
Good Practice: Go to Tools|Options|Field Mapping and set your own base classes as the defaults, this integrates your classes into VFP's IDE
You can use Tools/Options/Field Mapping to create a set of default classes that VFP will instance when dragging fields from the Data Environment. John Petersen has a utility that helps manage field mapping for different projects to different classlibs/classes. Alternately you can use the REGEDT32 program and save the key
HKCU\Software\Microsoft\VisualFoxPro\5.0\Options\IntelliDrop
to a file in each project folder. To switch project mappings all you have to do is double click the file in explorer.
Minor Rule: Minimize the number of classes stored in each class library.
Visual SourceSafe only lets one person check out a class library at the same time. Individual classes, be they stored in VCX or .PRG files, cannot be individually checked out. So checking out a class means checking out the library wherein the class lives.
Moreover the probability of finding that a particular library is not available for immediate exclusive use rises with the intensity of development, the number of concurrent developers, and with the number of classes in each library. These forces imply that you should, as much as possible, shoot for small class libraries.
Remember that Visual Class libraries, VCX files, are units of physical distribution. It's a good idea to use class libraries to package things that should be packaged together. If this is so, then checking out a class library should give you exclusive access to things that are functionally related. So when designing class libraries, think cohesion instead of type. In this sense, unless you work alone or in a very small team, having a class library for "buttons" or "forms" makes little sense.
Major Rule: Logically store your classes to minimize coupling.
At first glance segmenting classes into libraries appears simple: Keep first-level subclasses in one VCXes, all forms together in one VCX, cool controls together in another, with other VCXes for, say, composite classes, forms, toolbars, and so on. Everything is straightforward and, if anything, things are easy to find.
But the guiding principle of class library segmentation is coupling. Physically arrange your classes so that distributing and reusing them is not hampered by external dependencies. Classes that depend on each other should probably be stored together, or proximately in related class libraries.
Also, if you can avoid .H files, then do so. H files are a pain in Visual FoxPro.
Minor Rule: Don't store customized classes with "base classes" in the same library.
If you follow the general design rule that all classes should spawn from read/write culmination classes, then these culmination classes are required by all the classes in your application. Now to later reuse these classes, you'll want to minimize unnecessary baggage and detritus when referencing superclass class libraries. Do this by keeping superclass libraries very lean.
Consider also segmenting your base classes into visible and non-visible base class libraries, and other divisions as well. That way, if you need to reuse an abstract non-visual class somewhere else, you don't need to link-in the unrelated visual classes that just happen to be in the same package as its superclass.
Good Practice: Prefer short class names - _txt vs _textbox
Visual FoxPro's compiler just checks syntax. It doesn't check for proper use of things like class, field, and variable names. The longer your class names, the greater the probability of a typo.
Good Practice: Don't go overboard naming your classes according to their pedigree.
While it's generally a good idea to prefix or suffix class names according to a (or any) sensible naming convention, I don't recommend going overboard with hierarchical naming conventions. In other words, avoid naming classes like this:
Txt txtLevel1 txtLevel1Level2 txtLevel1Level2Level3
The reason for this is evident the minute you start redefining classes, which invariably happens if your class design isn't perfect.
Good Practice: Know when to store classes in PRGs, and when to store them in VCXes
Pros of PRG class libraries:
Cons of PRG class libraries:
Good Practice: Know the VFP metadata structures
VFP's VCX files are but DBFs by another name. In this light, all of Visual FoxPro's designers (class designer, form designer, menu designer, report writer, and project manager) are just data entry program to fill VCX, SCX, MNX, FRX, and PJX structures.
Sometimes the most efficient way of doing something is to open and edit the class library as a normal table. This means USE xxx.vcx EXCLUSIVE, then edit the contents of something like the ClassLoc field directly and close the file. Then execute 'COMPILE FORM xxxx' (if you are hacking a .SCX) or 'COMPILE CLASSLIB XXX' (if you are hacking a VCX).
Back the files up before you try this - if you make a mistake you could lose the whole structure.
A cool thing to do is write batch programs that can manipulate directories full of forms in one go. Something like the following code which re-pointers the class library location attribute for all the forms in a directory.
lnFormCount = ADIR( laForms, '*.SCX' ) FOR lnCnt = 1 TO lnFormCount USE ( laForms[lnCnt] ) EXCLUSIVE REPLACE ALL classloc WITH <newpath> ; FOR classloc = <oldpath> USE COMPILE FORM ( laForms[lnCnt] ) NEXT
Major Rule: The "class" of a VFP composite class applies only to the underlying container.
Visual FoxPro supports a variety of containership abstractions. Formsets can contain forms, forms contain controls, grids contain columns which contain controls, optiongroups contain optionbuttons, and containers and custom classes can contain almost anything.
You can have, for example, an address visual class used to display addresses that contain textboxes and labels and perhaps some interactive behavior. But don't be fooled by appearances: The only pure classy thing about a container of objects is the container. The objects in the container are instances of other classes.
When you put a textbox class in another container class, you are not creating a subclass of the textbox, you are creating an instance of it. A subclass of your container will contain textboxes that inherit from your base textbox class, not from changes you make in the textboxes in the superclass container.
Read Drew Speedie's article, 'Dangers of Composite Classes in Development' (FoxPro Advisor, Feb 1998). The general rule is only create composite classes that you intend to instantiate, not that you intend to subclass.
Minor Rule: Use your own classes in your VFP grids and commandgroups.
Add your textbox classes to the grid columns and remove the FoxPro base textboxes. Just drag your textbox from the forms control toolbar into the column, then to eradicate the original text box by selecting the FoxPro base textbox and press delete.
Minor Rule: Understand when you should, and shouldn't, bundle VCXes in your app.
Do you have to distribute class libraries within executables? No! You can choose to exclude any file from a project and as long as it is along SET PATH then VFP will find it at run-time. Of course, you'll have to remember to distribute the proper files, but this strategy buys you great update and customization flexibility.
Major Rule: Use Source Control to Protect Your Class Libraries
Henceforth I talk about Visual Source Safe, but what I say applies to PVCS or any other leading source control systems you might be using.
Good Practice: If you are in experimental mode, coding from the seat of your pants, use the Source Safe safety net.
I often find that I would like to be able to copy a class so that I can experiment with it without committing any changes. This is the sort of thing Visual SourceSafe lets you do. You can, at any time, rollback to any previous version.
Guideline: Realize that Source Control Integration comes with baggage
Visual FoxPro comes with source code integration, but you don't have to use it that way. In fact many developers I respect eschew source control integration and use the source control products interactively. There are many reasons for this. Foremostly you'll notice that Source Safe gets progressively slower as its source database gets larger. Secondly the VFP integration provides few of the features and control available with using the Source Safe client interactively. Third, irritating Source Safe dialogs come up and clutter your VFP desktop, and forth the integration is managed with poorly documented intermediate files that are prone to being forgotten or erased as you copy files around in your development environment.
Guideline: Occasionally clean out your Source Safe project.
Source control is overhead. If you are using source control integration and you find that response time for opening a file is beginning to lag, consider cleaning out your source control database. I suspect, but can't be sure, that Source Safe response time varies inversely with the size of the Source Safe database, which increases every time you check something in.
Good Practice: Be aware of some common problems with Interactive Source Control.
If every time you open a project you get the message: "An unspecified registry error occurred". This means the project is controlled by Visual SourceSafe, but you don't have VSS activated in VFP, or don't have it installed at all. If you really don't need the SourceSafe link, you can clear the SCCDATA field in the PJX file and set the LOCAL field to .T.
Guideline: VFP needs Read/Write privileges in order to compile its structures.
If you have a project that does not allow building, and you get the error message "Cannot Write to Read-Only Cursor", usually this means a read only file. You probably have of your SCX or VCX files is still set to read-only but not marked as checked into SourceSafe in the project file.
In order to compile forms and classes, those files have to be read/write. This is because VFP stores the compiled code in the VCT or SCT. You probably don't have some VCX or SCX files checked out so they are read only on your drive.
If you are using Source Safe interactively, when you do a Get Latest Version on all files in the project (including tables) make sure you have 'Make Writeable' box option checked. VFP needs many of its structures to be writeable since object code is stored as part of its metadata.

Hate speech is one of the most important topic in anti-oppression politics today; a great deal of energy and political will is devoted to identifying, characterizing, contesting, and (sometimes) penalizing it.
The inclusion of misogyny in a definition of what constitutes hate speech is generally controversial. Too often sexism is seen as a “second-class” offence, somehow less dangerous than racism or religious hatred. But it is not.
The outbreak of social media provided a new and free-access platform for people to incite violence and to spread patriarchy-enforcing mindset. Though even men can experience this kind of hate, women are more severely attacked and often insulted. With the online proliferation of hate speech, there is an urgent need to talk about whether someone is using any kind of harmful content that could generate more hate.
Analyzing the web is easy to find well-organized communities and groups of users against women. The aim of this project is to bring to the attention the opinion of small communities and their vision of female’s activism, using the Antifeminist Manifesto as a flagship worth to be followed.
The website’s strenght is focused on the textual part, that is taken from anti-feminist websites and it’s presented, un-edited, to the users. The fact that this kind of content, hyperbolic and without any logic, is really made by some people, create a sense of dissociation and at the same time gives an unseen perspective on what anti-feminists means. A tree-map visualization can help to better understand where do the contents come from, for each website the treemap visualize the number of characters selected for the text.
The website speaks mainly to users that don’t know much about feminism or even to the ones that identify themselves as anti-feminist, not understanding the cultural background they are associating themselves to. We also think is important to reach those people who think that equality has been achieved, not considering the importance of feminism and its principles.
The five points of the Manifesto ironically attempt to persuade the visitors to join the Anti-feminist movement, but the desired effect is the complete opposite. The website gradually show the power and the gravity of hate speech, going from the normalized forms of sexism to the most serious and brutal words used to discredit women. Indeed the project aim to bring awareness on this topic and sensitize the visitors, underlining the importance of being feminist in an era where is easy to share harmful and offensive contents.
The Anti-Feminist Manifesto was born as part of the Final Synthesis Lab final project at Politecnico di Milano. The Lab, held by Density Design research department, aims to analyze and engage the public about complex and controversial social issues through the analysis of data contents. The website’s elaboration is consequential to the research “Do we still Feminism?”, a project which aim to analyze different aspects of feminism online and to identify the different personalities involved in the discussion.
“The Anti-feminist Manifesto” is entirely designed to create a distorted view of reality. The contents are absurd but, at the same time unique, so their job is to take the user through the path defined by the five statements and create a sense of alienation and astonishment.
Each statement summarize the best of the comments online and it is proposed with the same repeated formula to represents a sort of collection of commandments, rules to define women and their role in the society. The statements represent the main arguments used by anti-feminist public, who reveal themselves misogynists because of such offensive content.
We included text descriptions, which are composed with comments found on the anti-feminist communities; even the visual illustrations and graphics are the result of elaboration of those contents. Going deeply, the alienation effect is much more evident, thanks to the interactive parts whose job is to improve the usability.
A note on language: we recognize and respect that many words are offensive without just context. Those words are just reported to increase the power of the project and sensitize the users, without any other intent.
In order to track its dissemination potential of the project we created some simple visualization to register some interesting data about the users that visit and share the link. We are able, thanks to this process, to see the resonance of “the AntiFeminist Manifesto” and prove the feasibility of campaigns of this kind.
The launching campaign of the project consists in a series of provocative posters in which the pillars of the anti-feminist’s believe are postulated. On the affiche is simply written in large letters: “All women are” followed by a sexist insult.
No further clues are given to the reader whose reaction should be astonishment and disdain. The provocative effect should be maximized by the absence of an explicative payoff and push the reader to follow the link to “The Anti-feminist Manifesto” on the poster.
Once landed on the web-site the user is immersed in a “fun-but-not-really” series of hate-speech comments against women disguised in funny interactive visualizations. Eventually the user discovers the real aim of the project and shares the message through a post on different social media.
We expect people to react in a very emotional way, for this reason we left on the poster a lot of blank space to allow people to write their reactions (and eventually share the poster social media.)


When one wishes to test a load and execute mechanism with the Beaglebone Black Programable Real Time Unit (PRU) typically a simple program implementing some sort of visible action (such as toggling an output) is used. In the microcontroller world the simple "Blinking LED" is pretty much the equivalent of the "Hello World" program.
The USR3 LED is a good choice for such a demonstration item as it is already present on the Beaglebone Black board, it is quite visible, and is usually unused by anything else. Furthermore, in order to toggle an external pin high or low, the associated GPIO must be enabled in the PinMux. It so happens that, by default on most Beaglebone Black systems, the USR3 LED is tied to a GPIO that is usually always enabled in the PinMux. This means that you probably do not have to worry about Device Tree Overlays in order to configure the appropriate GPIO so the PRU can turn the USR3 LED on and off.
The example below discusses how to use the BBBCSIO libraries PRU_Driver class to load a PRU binary (compiled PASM Assembler). The example binary being loaded will blink the USR3 LED once per second for ten seconds. If you are new to the Beaglebone Black the image below illustrates the location of the onboard USR3 LED.
NOTE: The code the example below will run in the PRU is called PRUBlinkUSR3LED.bin
and the PASM Assembly Language source for this code can be found in the file
BBBCSIOHelp_PRUBlinkUSR3LEDExamplePASMCode.html. You should probably read the comments in the PRUBlinkUSR3LED.p
source file in order to understand the operation of this program.
The example code running in the PRU uses a GPIO value of 88 which is exposed as GPIO1_24 and has a hard wired connection to the USR3 LED. In most cases this pin will be available as an output. Be aware that if you decide to use a different GPIO as an output you CAN NOT necessarily assume that that pin is available as a GPIO on your Beaglebone Black and even if it is a GPIO you still cannot assume it is set as a GPIO output (as opposed to being an input). Any one pin can be used internally for any of about half a dozen different peripherals (UART, SPI bus, PWM, A/D, HDMI, EMMC etc) and it is not a given that a randomly chosen GPIO or any specific GPIO is available.
So, before using other pins, you will need to ensure that the associated GPIO is configured as an output. There is no code you can call in the BBBCSIO library which does this. You MUST configure the GPIO externally prior to running your executable - usually this is done by editing the device tree.
The code below illustrates how to use the PRU_Driver class to launch a compiled PRU binary. Other than the launch there is no output.
/// +=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+= /// <summary> /// Configures a PRU and runs a compiled binary in it. /// </summary> /// <param name="pruID">The pruID</param> /// <param name="binaryToRun">The binary file to run</param> /// <history> /// 05 Jun 15 Cynic - Originally written /// </history> public void PRUBlinkUSR3LED(PRUEnum pruID, string binaryToRun) { // sanity checks if (pruID == PRUEnum.PRU_NONE) { throw new Exception("No such PRU: "+pruID.ToString()); } if ((binaryToRun == null) || (binaryToRun.Length == 0)) { throw new Exception("Null or zero length binary file name specified"); } // build the driver PRUDriver pruDriver = new PRUDriver(pruID); // run the binary pruDriver.ExecutePRUProgram(binaryToRun); // close the driver, the code in the PRU remains running pruDriver.Dispose(); }
The PRUBlinkUSR3LED
call would be made via a line which looks like:
PRUBlinkUSR3LED(PRUEnum.PRU_0, "/home/debian/CSharpCode/PASMCode/PRUBlinkUSR3LED.bin");

Patterns: Singleton
The singleton pattern is a design pattern that restricts the instantiation of a class to one object. This is useful when exactly one object is needed to coordinate actions across the system. The concept is sometimes generalized to systems that operate more efficiently when only one object exists, or that restrict the instantiation to a certain number of objects. The term comes from the mathematical concept of a singleton.
Features of the Singleton pattern
- Lazy construction.
- The singleton object is not created until it is needed to be used for the first time.
- The constructor is private so you can not build new instances of the object.
- The constructor is only ever called by the getInstance function if the object does not already exist.
Code example
A typical singleton pattern in JavaScript looks like this.
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 |
|
Lets look at what we have created.
An instance variable that is set to null, this will hold our instance of the singleton when the getInstance function is called for the first time.
An init() function which will build our singleton. It can contain private and public variables and functions.
A public getInstance() function. This will return the instance if it already exists and or if it doesn’t, it will create it, set our instance variable and then return it.
That’s all there is to it.


Pair programming is when two developers are working together on a project in real time. Common practice is for one developer to verbally guide the other, while the other developer works directly with the code. It is important for the two people working together to do a check-in with each other to get a sense of how each is feeling. If someone hasn't had sleep or is dealing with something in their personal life, it may be important to know these things up front because they can affect productivity.
Many people assume that programmers work independently, but this isn't typically the case. Developers work with other people in teams. Pair programming can help you become a better team member and developer by learning from your pair and exchanging feedback. Pair programming lets us know where our strengths and weaknesses are relative to other programmers, so that we can work together to focus on improvement.
The Driver is the person who is in front of the screen working with the code, while the Navigator is directing the actions of the driver. Navigators will often be looking up code or other references to make sure the pair is on track. The driver's job is to "keep her or his eyes on the road," and let the navigator give all directions.


This week I reviewed the data collected on my duration goals and conducted a usability test on my blog. I also learned about creating content experiments using Optimize. This allows me to see if changing features on my site will affect the progress towards my goal. This week’s blog focuses on the data collected on my goals and what I have learned so far.
What I learned about my goal’s performance
Data collected using Google Analytics
I had 57 goal completions with the following breakdown:
Because my goals were increasing duration in time, the total completion results have duplicates. A person spending one minute on my site shows up under both the 30 second and 1-minute goals. To adjust for this, I’ve noted completion by goal. Completion of goal shows the actual number of times a goal was met. The percentages show that most people spent five or more minutes on my site which is much more than I expected for a blog. I assumed that most people would spend about a minute before leaving.
Results of usability test
I contacted three people to conduct a usability test. I asked them the following questions:
- Estimate how long you spent on the site (based on the three goals)
- Which parts of the website were most interesting?
- Which parts of the website were least interesting?
- How do you think the site could be improved?
User 1 said they spent more than five minutes on the site. The two latest blogs with the Google Analytics information were most interesting. They enjoyed seeing the data and my conclusions. The least interesting parts were earlier blogs that just discussed formatting techniques and didn’t include data techniques. They didn’t really see any need for adjustments.
User 2 was very similar to user 1. They spent more than five minutes and liked the Google Analytics more than the earlier blogs on design. In terms of improving my site, they suggested expanding the content to do more data analysis.
User 3 also spent more than five minutes on the site but found the earlier blogs to be more interesting than the data analytics. They suggested that I should consider using more images or visuals on my site and making periodic updates with pictures.
Setting up my content experiment
Changes made
Because I had duration goals, it was hard to decide on what changes to test. I decided to create a Call To Action (CTA) and changed the subheading on my homepage to encourage people to check back weekly and spend time on my site.
I created an A/B test in Optimize and sent users to the two versions of the site. I used a 50/50 variant weight, to send users equally to both versions of the page.
How the process went
I had some difficulties setting up my content experiment in Optimize. It took me a while to notice the code that I had to add to my blog code. After I added it in visual studio code and pushed it to Github it took several hours before I could validate that my installation worked. Once I had validation of the installation, I tested the site but couldn’t get variant 1 to render. After thinking about it for awhile I realized that I never pressed start. Go figure!.
