' ELIAHU NISSIM ATTORNEY SUPPRESSION OF FLUTTER ORIGIN OF THE INVENTION The invention described herein was made in the performance of work under a NASA contract and is subject to the provisions of Section 305 of the National Aeronautics and Space Act of 1958, Public Law 85-568 (72 Stat. 435; 42 USC 2457).
BACKGROUND OF THE INVENTION This invention relates to an aerodynamic control system to control flutter or other oscillatory motion and more particularly to a control system including pairs of leading and trailing edge control surfaces, each pair operated in concert by a stability augmentation system to damp out torsion and bending of the oscillating member. For the typical large commercial aircraft and particularly for an aircraft such as a supersonic transport, the weight penalty incurred when structural stiffness is increased to avoid flutter problems makes such a choice highly costly if not prohibitive. An aerodynamic control system which actively combats flutter becomes the more attractive alternative from both weight reduction and fatigue life standpoints. Such a system will be called on, however, to suppress flutter, alleviate gust response and control vehicle instability despite the influence of such variables as oscillatory frequency, mode of vibration, subsonic Mach number, mass, stiffness, elastic axis location, or center-of-gravity location of the system.
Flutter typically consists of both torsional (or twisting) and bending (or plunging up and down) motions. Active control of, for example, wing flutter has heretofore involved the use of a trailing edge, hinged control surface. The inability of a single trailing edge (or a single leading edge) control to simultaneously damp certain combinations of torsional and bending motions of the fluttering member has led to the development of the cooperating leading and trailing edge control system. If, as will be subquently explained, the deflection of the single trailing edge control is initiated to counteract bending, the deflection may actually reinforce torsional motion. With the leading edge, trailing edge cooperating pairs of control surfaces, deflection of one control surface may be used to counteract bending while simultaneously deflection of the other control surface may be used to oppose torsional motion. Thus the cooperating leading edge and trailing edge control surfaces enable both the torsional and bending motions associated with flutter to be opposed simultaneously.
SUMMARY OF THE INVENTION The active aerodynamic control system includes at least one pair of control surfaces located on the leading edge and trailing edge of the fluttering member. At least two sensors located on the fluttering member adjacent to the control surfaces are used to obtain the effects of flutter upon the member in terms of torsional or bending deflections or the time derivatives of these deflections. Information thus sensed is transmitted to a stability augmentation system as electrical input signals. These input signals are converted into control deflections of the leading edge and trailing edge control surfaces. A feedback loop insures the attainment of the computed deflections. The conversion factors which enable input signals to be transformed into control deflection signals are obtained by a theoretical optimization process to be subsequently discussed. Certain of these conversion factors primarily affect control response to flutter while certain other conversion factors predominate in gust alleviation or vehicle stability augmentation.
An aircraft which is dynamically represented by n modes of vibration may require, at most, n/2 pairs of leading and trailing edge controls. Control of the conversion factor relating main surface angles of attack caused by flutter to leading edge control surface deflection angles prevents unfavorable flutter interaction between rigid sections of the fluttering member and sections of the flutter member bearing the hinged leading edge and trailing edge control surfaces.
Flutter of a wing having a deformable chord section may be controlled by careful placement of the flutter sensors. Placement of rotational sensors upon the control surfaces themselves to measure control deflection due to chordwise deformation provides a reference for the control loop of the stability augmentation system. Deflection signals from the stability augmentation system are compared with the deflection of the control surfaces caused by chordwise deformation to determine the necessary correctional deflection.
Stabilization of rigid body modes of the vehicle may be controlled by careful positioning of the pairs of control surfaces in relation to the vehicle center of gravity and by using such paired controls on tail as well as wing members. A brief analysis of control power requirements has revealed that the power necessary to run such a control surface system is within the capabilities of modem-day systems.

DESCRIPTION OF THE PREFERRED EMBODIMENT Referring now more particularly to the drawings wherein like numerals identify like parts throughout the several views, and more particularly to FIG. 1 there is shown a symmetrical air-foil section 10 having a trailing edge control 11 and a leading edge control 12. Controls 11 and 12 are hinged to move up or down and have an equal chord-wise dimension. A symmetrical section and controls of equal chord length are chosen only for purposes of illustration and the invention is not so limited.
FIG. 2 shows an airfoil section 10 in schematic. Airfoil 10 is fluttering wherein it is displaced a distance h from a reference chord and rotated relative to the reference chord at an angle a The fluttering motions can be detected by two sensors 13 and 14 which are located on or in airfoil section 19 at a known distance in terms of percent chord) from the leading edge. Forward sensor I3 and rearward sensor 14 sense either displacement from the reference chord h and h or a time derivative (velocity or acceleration) of such displacement. Moreover, as an alternative scheme, a rotational and a linear motion sensor may be co-located at to measure the rotation of section 10 about its mean aerodynamic center and the displacement of the section 10 from the reference chord.
Chord length of airfoil 10 is defined by For 2b. The deflection angle of the leading edge control 12 relative to the controls neutral chord line is 3 while deflection of the trailing edge control 11 gives the angle 8 FIG. 3a shows a schematic example of a stability augmentation system utilizing signals from two linear accelerometers corresponding to sensors 13 and 14 in FIG. 2 which are .4 Eapart. Calculating or knowing the frequency of oscillation w the distance b (from FIG. 2) and the transfer functions G(2,1), C(2,1), C(2,2), G(2,2), C(1,1), G(1,2), G(l,l and C(l,2), the stability augmentation system can calculate the control deflections [3 and 8 The functions denoted G are out-ofphase (i.e., in quadrature with respect to the displacements) whereas all other are inphase which will be discussed in detail later.
The embodiment of the invention disclosed in FIG. 3a includes two linear accelerometers and 31 which correspond to sensors 13 and 14, respectively. The output of accelerometer 30 is a signal proportional to h (the second derivative with respect to time of h, shown in FIG. 2) and the output of accelerometer 31 is 5 (the second derivative with respect to time. of h-,,). The signals h, and h are applied to a subtractor 32 which produces a signal propoitional to Bf T1 This signal is divided by a constant term .45 with a divider 33 to produce the signal if The signal Ii, is divided by the constant term b with a divider 33 to produce the signal ii, lb The signals il /b and ii are integrated by inte rators 35 and 36, respectively, to produce the signals /band c't These two signals are integrated by integrators 37 and 38, respectively, to produce the signals h /b and a The signals h lb and d are also divided by m with divider 39 and 49, respectively, to produce the signals ih,/b and ia The signal 0. is produced by an analog computer from the output of one of the linear accelerometers 30 and 31, or a different accelerometer at another location could be used to supply the input to computer 41. Different methods are available that can be mechanized by computer 41 to compute w One such method is based on the simple harmonic motion relationship m [acceleration l displacement .Another method measures period" by detecting zero-crossings. Also m can be made to be constant with some loss of effectiveness of the system.
The signal ih /b is applied to multipliers 42 and 47; the signal h /b is applied to multipliers 43 and 46; the signal in: is applied to multipliers 45 and 48; and the signal a is applied to multipliers 44 and 49. The outputs of multipliers 42-45 are summed by an adder 50 to pro duce the signal 8 and the outputs of multipliers 46-49 are summed by an adder 51 to produce the signal B The signal 6 is applied to a trailing edge controller 52 which controls the movement of a trailing edge control element 53, and the signal B is applied to a leading edge controller 54 which controls the movement of a leading edge control element 55. Controller 52 and controller 54 can be any device, such as a servo motor, that will convert an electrical signal into a mechanical motion. A sensor on each control surface senses the deflections of the control surfaces B and 8 The error functions (B -B) and (S -6) are then formed through the normal feedback design. These control surface sensors and the feedback loops are well known and are not shown in FIGS. 3a and 3b. Similarly, the other elements shown in FIG. 3a are well known and hence are not disclosed in detail in this specification.
FIG. 3b differs from FIG. 3a in the use of a constant reference frequency to, rather than an actual (measured) frequency w and in the flutter sensor inputs. Here two flutter sensors are colocated on the wing section (see location 15 in FIG. 2) to sepse rotational acceleration ii and linear acceleration ii The structure in FIG. 3b differs from that in FIG. 3a in that an angular accelerometer 56 is used in place of linear accelerometer 31 and subtractor 32, divider 33 and analog computer 41 are not used. That is, the output of accelerometer S6 is applied directly to integrator 36, and a), is a constant.
FIG. 4 shows a wing 20 having a wing tip 21 and several pairs of leading and trailing adge control surfaces 12 and 11. For convenience the pairs of controls may be referred to as outboard, inboard, midspan in like manner as aircraft engines placed along a wing.
FIG. 5 shows a vehicle 15 having a swept wing 20 and a pair of leading edge 12 and trailing edge 11 controls placed well aft of the vehicle center of gravity 16 because of their outboard location.
A deformable-chord wing section 10 is shown in FIG. 6a. The center section of the chord of wing section 10 between flutter sensors 13 and 14 (see also FIG. 2) is practically rigid. The more flexible leading edge and trailing edge sections of the chord wherein controls 12 and 11 are located are also equipped with position sensors 17 and 18 to measure the approximated chordwise deformation of the leading and trailing edge chord sections. Sensors l7 and 18 may be rotational accelerometers placed on the leading edge and trailing edge controls near the control hinge line.
The deformation of the deformable chord wing section 10 may be approximated by wing section 10 shown in FIG. 6b. ar represents the equivalent angle of attack of the deformed-chord wing section 10 while [3,, and 8 represent the equivalent leading and trailing edge control deflections for the deformed chord section 10. 17 and a 18 represent the angular movement of the leading and trailing edge portions of the chord measured by sensors 17 and 18.
OPERATION The operation of the present invention is now believed to be apparent. FIG. 1 shows the effects of the (downward) deflection of leading and trailing edge hinged control surfaces. Using, for example, a symmetrical airfoil with its chord line alined with the relative wing in FIG. 1a gives zero angle of attack and zero camber when controls are undeflected. Downward deflection of a trailing edge control as in FIG. 1b causes chord line rotation to a positive effective angle of attack as well as changing wing section curvature to give positive camber. These two effects are additive. Downward deflection of a leading edge control as in FIG. 1c causes chord line rotation to a negative effective angle of attack although camber is changed positively. Therefore the camber change caused by the deflection of the leading edge control (up or down) is partially offset by chord line rotation giving unfavorable or negative angle of attack change. At this point, we note the inherent advantage of the trailing edge control to change section lift as against the effect of the leading edge control.
Operating the leading and trailing edge controls in opposite directions as shown in FIG. M can give, in essence, a symmetrical section at a positive angle of attack which will produce increased lift despite the fact that camber-wise the two controls appear to be working at cross purposes. Putting angle of attack effects to one side, the control deflections shown in FIG. 1b and FIG. 10 produce higher lift through an increase in camber. From basic aerodynamics a positively cambered airfoil typically produces a negative (nose down) pitching moment about the aerodynamic center (a.c.) whereas pitching moment about the a.c. of a symmetrical section is zero. Thus, the configuration in FIG. 1b and FIG. 10 will produce positive lift accompanied by (negative) nose-down pitching moment about the a.c. whereas the configuration in FIG. 1d can produce positive lift and zero moment about the a.c. Moreover, leading edge deflection as in FIG. 10 will produce large moment change in comparison to lift change.
Here is the advantage with respect to flutter control of operating leading and trailing edge controls in concert. Flutter analyzed at a section along the wing span involves a bending, wherein the wing section oscillates up and down in translation, and a twisting, wherein the wing section oscillates noseup and nose down in rotation. To combat the flutter at this wing section, lift must be produced to counter the bending and moment must be produced to counter the twisting. With the trailing edge or leading edge control alone, the control deflection required to produce the needed lift may or may not also produce the needed moment about the a.c. Using the two controls in concert permits variation of camber and angle of attack to produce the proper balance of lift and section pitching moment to simultaneously combat both twisting and bending. Although the controls work in concert, the trailing edge control (as discussed before) is the more effective in influencing lift while the primary (but not the only) use of the leading edge control is in controlling the moment about the a.c.
To control flutter, the twisting and bending motions must be measured along a section of the wing containing the leading and trailing edge control surfaces. The frequency of oscillation must also be measured if the scheme described in FIG. 3a is used, whereas the scheme in FIG. 3b uses a constant reference frequency. At least two sensors are required to measure the two flutter motions. As shown in FIG. 2, two accelerometers 13 and 14 are mounted on the wing adjacent but not on the control surfaces. FIG. 2 shows the desired data h, and h which represent the displacement of the sensors 13 and 14 from a reference chord. Sensors 13 and 14 are spaced .4 chord apart for the purpose of illustration of the flutter control technique and to satisfy the trigonometry of FIG. 3a which shows the block diagram illustrating the operation of a stability augmentation system computer. The accelerpmeter s 13 and 14 transmit linear acceleration signals h and h which give b2 by simple trigonometry. Double integration yields il and a Frequency 0) is obtained by actual measurement in the FIG. 3a method.
In FIG. 3b an alternate sensor scheme is shown whereby a rotational accelerometer supplies ii and a linear accelerometer supplies Ii to the stability augmentation system. The two sensors may be co-located as shown in FIG. 2, location 15. a and h are then found directly by integrations. Also in FIG. 3b, a constant reference frequency is used in lieu of measurement of the actual frequency. It can be shown that this constant frequency approximation will not greatly affect flutter suppression with a leading/trailing edge control system.
The last blocks on the right of FIG. 3a and FIG. 3b are transfer functions which are found through an optimization process. the i terms just to the left of the transfer function blocks represent of phase lead terms which are intended to produce damping. The other (non i) terms are real response terms to oppose the bending or twisting deflection which is sensed.
The governing equations for the computation of control deflection angles B and 8 (see FIG. 2) as shown in the block diagram in FIGS. 3a and 3b are:
The C and G terms in equations (1) and (2) are transfer functions transferring h and a which are measured by sensors 13 and 14 (or 15) and portions of the computer as shown in FIG. 3a and FIG. 3b which convert electrical signals into B and 8 values. These C and G transfer functions may be thought of as gearing ratios between the motions of the main surface h and a and the deflections of the control surfaces B and 8 These transfer functions may be written in matrix form for optimization by electronic computer as:
One such optimization resulted in the following values of the transfer functions:
In the diagram of FIGS. 3a and 3b, those terms in equations (1) and (2) which do not influence flutter appreciably are G(l,l), C(I,1) and C(2,l). Transfer function C(2,l) does have predominant importance in controlling rigid body modes. This is an important feature of the stability augmentation system. Since the transfer functions affecting flutter are relatively independent of the C(2,1) term which primarily affects rigid body modes, control of elastic and rigid body modes can be achieved by the same system. Since gust response problems are analogous, the leading/trailing edge control system can provide very efficient gust alleviation. Thus a novel feature of the invention is to combine control of elastic and rigid body modes and gust response in one package. The 1' terms are, once again, 90 phase lead terms which anticipate the motion of the wing vehicle in an attempt to damp flutter, control instability or alleviate gust response. The other (non i) terms produce control deflections in direct response to the sensed wing or vehicle motions.
Optimization of each of the transfer functions was accomplished by calculating and plotting eigenvalues for the aerodynamic energy matrix against the inverse of the nondimensional reduced frequency Velocity/cob) for a series of values of each transfer function taken separately. The optimum value of the transfer function was defined as that value which produced the best performance of the minimum eigenvalue across a range of Velocity/rub) Sensitivity of curves of minimum eigenvalue against the inverse of reduced frequency Velocity/(ob for off-design values of the transfer func tions are necessary to determine just how much accuracy is required. G(2,2) and G(2,2) were found to be the most sensitive parameters. Rough assessment of the power required to drive the controls revealed little or no problem in this area if one starts computing with low values of the transfer functions to insure small control deflections and especially if G( 1,1), C( 1 ,1) and C(2,] are ignored as insignificant in the flutter application. Investigations of compressibility effects have shown those effects to be beneficial to the optimized control system producing high eigenvalues at high values of Velocity/rub In arranging a certain limited number of leading and trailing edge control pairs along the wing span as in FIG. 4, care must be taken to insure that solid chord sections of the wing do not exert an adverse effect upon flutter. Upward deflection of a trailing edge control in response to lift buildup causes a nose-up moment about the aerodynamic center (a.c.) which could affect the frequency of the wing so as to place the wing beyond the optimization frequency range. However, if the value of C( 1,2) is set so that regardless of trailing edge deflection upward, leading edge deflection downward rotates the chord to (effectively) a zero camber position as in FIG. 1d, there can be no moment about the a.c. and no detrimental effect upon wing frequency.
In suppressing flutter of a particular wing, the flutter equations are solved to obtain the flutter speed. Examination of wing deformation at this speed determines the most aerodynamically efficient location along the span for a pair of leading and trailing edge controls. This positioning depends upon the fourth power of the half chord (b and the square of the response vector q Since the fluttering wing generally responds most violently at its tip, this may be the control pair location for constant chord wings. For tapered wings the factor moves this location inboard. The flutter equations are again solved to obtain the flutter speed with one pair of leading and trailing edge controls. If the increase in flutter speed is insufficient, the above procedure is repeated by adding additional pairs of controls, one at a time, until the whole speed range is cleared. Generally speaking, a wing having n modes of vibration may require, at most, n/2 pairs of controls with care being exercised to insure that all possible mode shapes within the frequency band that activates the controls are considered.
In allowing the pilot to control the aircraft, a lower frequency limit can be set by using a washout" filter which permits aircraft response to pilot-initiated control deflections. At the high frequency limit to avoid large phase lags with amplitude changes, integrations of accelerometer (sensor) signals and feedback error loop signals can be made to down-weight these signals at the higher frequencies.
The effect of control placement upon rigid body modes must be considered. FIG. 5 shows a leading and trailing edge control pair 12 and 11 mounted near the tip 21 of a highly swept wing 20 and therefore well aft of the vehicle center of gravity 16. When the control pair 12 and II reacts to combat lift buildup (for example) due to flutter the resultant downward force behind the center of gravity induces a destabilizing nose-up pitching moment affecting the vehicle. Such effects are combatted passively by the use of a washout filter and actively by placement of a leading and trailing edge control pair on the horizontal tail plane or canard surface, introducing a linear stiffness term through adjustment of the transfer function C(2,l By fitting control pairs to the horizontal and vertical tail flutter of the tail separable from those terms primarily influencing flutter, permitting separate treatment and optimization.
The problem of chordwise deformation due to twisting may be met by installing rotational accelerometers on the leading and trailing edge controls near their hinge lines as shown in FIG. 6a. Sensors I3 and M are mounted on a center chord section which is assumed rigid. Signals from sensors 13 and 14 are processed to give control deflections [3 and 8 as before and also to find a... see FIG. 6b. Signals from the sensors 17 and 18 are processed to give the angle a 17 and 18 which correspond to the control deflections caused by chordwise deformation. Knowing '17, 18 and at B.. and 8,, can be found where the subscript e denotes equivalent deformed chord deflection. The eror function of the feedback loop can now serve the dual purpose of subtracting out the equivalent control deflections and insuring control movement which results in attaining B and 8 as on a rigid chord section.
Although the invention has been described and illustrated in detail in a specified embodiment thereof, it is to be understood that this description is by way of illustration only and is not to be taken as limiting on the applicants invention. Obviously, there are many modifications and variations of the present invention possible in the light of the above teachings. Any body moving through a fluid susceptible to oscillation or flutter or any protruding member is the proper subject of the invention. The sensors used to determine a and h may be a combination of a rotation displacement and linear displacement sensor or a sensor of any time derivatives thereof or two linear displacement sensors or sensors of any linear displacement time derivatives although the preferred embodiment employs two linear plane can be suppressed and rigid body modes as well as gust response may be controlled as well. In fact, gust alleviation terms in equations (1) and (2) are generally accelerometers. Sensors location must be at a wing or empennage (or other surface) section where the control pair to be operated is placed and are located near but not on the control surfaces. Airfoil shape is immaterial to the invention. It is anticipated that for landing, some of the control pairs might be used as flaps for reducing stall speed. Some control pairs might be used for maneuvering while others serve only to suppress flutter or damp other oscillations. While hinged, flapped controls are used, deformable leading and trailing edge sections would also serve the purpose of the invention. The use of spoilers with the leading and trailing edge controls, while increasing drag might serve to overcome flutter problems in an unusual case. Hinged, slotted controls might also be used.

Recent Borrego Springs Reviews
Great cabin!
My four friends and I rented the cabin for the weekend . It was clean and well maintained . Very fast response time from the owner . The deck in the back had great views of the sunset . We all felt so relaxed and it was nice to get away from the city . Bbq grill in the back . It was a little difficult to find due to my phone not having service . It was only certain areas though and the cabin does have wifi . I suggest writing out directions first just incase you lose signal for a few while trying to find it . Other than that it was hidden in the woods and not a far drive from the town . Also Lake Cuyamaca is not too far away either . We definitely enjoyed ourselves and will be returning again next year !
When we first arrived the homeowner greeted us. He was very friendly and nice. We were greeted with pie that was delicious! Really quaint house. It was nice and it has the most amazing view. There is also great record collection to listen to. I highly recommend this place! It is great and waking up to the mountains made my trip!
Girls Trip 14
We had a wonderful time at this home. The owner bent over backwards to provide us with everything that we needed to make our stay most comfortable. The house is a great layout. We would definitely come back and stay at this house again. Thank you!

The University of Minnesota women's gymnastics team showcased why they are the best in Minnesota Saturday by scoring a season-best score of 195.425 at the annual Best of Minnesota meet. The Gophers were guided by sophomore Kayla Slechta, who tied three season-best scores and set a new all around superlative of 39.200.
Minnesota began the meet with a solid performance on vault, scoring a 48.725. The Gophers were led by freshman Jenny Covers, who tied a personal best score of 9.800. Coming in second and third, respectively, was Slechta with a 9.775 and freshman Cierra Tomson with a 9.750.
The Gophers continued their dominance as they headed into the second rotation on uneven bars. Senior Lucy Ennis was the meet's top performer in the event with a season-best score of 9.850. She was followed by Slechta, who tied a season best of 9.775, and Tomson, who tallied a 9.750. Minnesota ended the rotation with a score of 48.775, which is a season best on the event.
The Maroon and Gold followed their season-best score on bars with another season-best performance coming on balance beam, scoring a 48.925. Junior Shannon Golich put together an impressive routine for Minnesota and tallied a season-best score of 9.875. Slechta and fellow sophomore Dusti Russell were next in line as they each posted a 9.800, which tied a personal best for Slechta. Senior Briana Jones also had a solid routine as she set a new personal best with a 9.775.
Minnesota closed out the meet with having a trio of Gophers score a 9.800 or higher on floor while the team combined to tally a 49.000. Slechta and Russell tied for the meet high score as they each had a 9.850, which tied a season best for Slechta. Freshman Kylie Schermann rounded out the top three by tying her personal-best score of 9.800.
In the all around, Slechta claimed the crown with a personal-best score of 39.200 while Russell came in second and tied a career best of 39.025. Freshman Cierra Tomson rounded out the top three with a score of 38.850.
The Gophers are back in action at home next weekend as they host Big Ten newcomer No. 8-ranked Nebraska. The two foes will face off Saturday at 6 p.m. in the Sports Pavilion. The meet will not be available through Gopher All-Access because the Big Ten Network will be filming the meet, which will be shown at a later date on BTN.
Gophers Tickets on Sale Now
Pick-Your-Packs and single-event tickets for multiple sports went on sale the morning Sept. 14.
Gophers Release 2017 Competition Schedule

If all of the gift-giving at Christmastime gets to be too much, you might want to consider having a Buy Nothing Christmas.
Buy Nothing is a movement started by a group of Mennonites in Western Canada in 2001 as a way of saying no "to the patterns of over-consumption of middle-class North Americans," says its website, buynothingchristmas.org. (Representatives from the site could not be reached for an interview.)
Ashley Cameron is a local supporter of a Buy Nothing Christmas.
"It really bugs me how much consumerism has engulfed what Christmas represents," says the 21-year-old from Halifax. "I thought this was a way I could support my beliefs."
Cameron is a Christian whose faith is very important to her.
"To me, Christmas is supposed to represent Jesus' birth. I feel the world has taken advantage of that and taken money from it. And then you've got Santa Claus and stuff. They've built it into something it wasn't supposed to be. So I'm trying not to support that."
But it isn't just faith-minded people who are into the idea of removing the consumerism from Christmas. Brad Milligan is a 26-year-old atheist and anti-capitalist from Halifax.
Last year, he had what he called a "China-free Christmas," meaning the gifts he bought for the four people on his list had to be locally made. His China-free Christmas is expanding this year---he won't be buying or receiving Christmas gifts at all. He says that even if he was religious, he doesn't understand why that translates to buying stuff at Christmas.
"I still don't see [why] I should go out to Walmart and purchase gifts for my friends and loved ones that were made in China," he says. "I've never been able to make that connection."
But isn't not buying gifts bad for our economy?
"Yes, and now we're getting close to the core reasons for why Buy Nothing Christmas is necessary in the first place," says the Buy Nothing Christmas website. "Our economy is based on a consumer driven capitalism...if we stop shopping, we stop the economy."
Simply put, our economy depends on people to buy stuff, both stuff they need and crap they don't need. But even a Buy Nothing Christmas recognizes that some things need to be purchased, as does Cameron.
"I might make some gifts for people," she says, allowing that making things can require certain purchases, "but I'm not going to be buying any new items for anybody." Cameron says these gifts will have meaning and purpose.
But if you feel you need to purchase something this Christmas, you might keep in mind a few things, as endorsed by the Buy Nothing folks: Stick to locally, fairly traded goods in environmentally friendly packaging, recycling or re-using, or buying items that are built to last.

In between selling iPhone cases (yes, really) and paying for product placement on the latest season of House of Cards (yes, really), OnePlus seems to have achieved something rather cool on the software front.

In reaction to the recent attacks on Linux Mint, many measures were taken to reduce the risk of future intrusions, but we also worked on the eventuality of being hacked again.

Android 6.0 Marshmallow Update For Samsung Galaxy S6 Edge, S6 Edge+, Note 5 Delayed Under Telus, But Galaxy S6 On Course
Starting with home-country South Korea, the Android 6.0.1 Marshmallow update has been rolled out to several Galaxy S6 series of handsets and Galaxy Note 5 in selected regions, across the globe. Canada's Telus, on the other hand, recently published the Marshmallow update schedule for carrier-branded version of a slew of devices from various Android OEMs.
Collabora is not all that known by regular Linux users since they mostly do work that involves enterprise settings. It's important to know that even if they use LibreOffice for Collabora Office, they are also contributing upstream. In fact, Collabora is one of the biggest contributors, if not the biggest, for LibreOffice. You might wonder
The latest malware scare might be the most terrifying to date. Mobile security company Skycure co-founders Adi Sharabani and Yair Amit announced at the RSA conference in San Francisco this week that a new form of malware puts a vast majority of Android device users at risk. Called "accessibility clickjacking," it's one of the more
With both the Galaxy S7 and LG G5 sporting expandable storage, and Google adding great SD support to Android 6.0, this year it seemed like storage enthusiasts would get everything they could ever want. Apparently that's not the case though, as both OEMs have shunned Google's new "Adoptable Storage" feature. Samsung laid out its thoughts
Day 2 of Mobile World Congress was awesome. The overarching theme of the day was again focused on NFV (Network Functions Virtualisation). But before we get to that, I'm excited to announce that Canonical received a Best of Show award from Trusted Reviews for the BQ Aquaris M10 Ubuntu Tablet. A huge crowd gathered to […]
A total of five kernel vulnerabilities discovered by various hackers and developers in the upstream kernels have been patched in the Linux kernel packages of Ubuntu 15.10 (Wily Werewolf), including those of Ubuntu 15.10 for Raspberry Pi 2.

I'm sorry I have to come with bad news. We were exposed to an intrusion today.

A custom firmware based on Android 5.1.1 Lollipop update was released for Samsung Galaxy Note 3. Owners of the 2013 phablet released by the South Korean tech giant can now opt to install Android 5.1.1 Lollipop update through FlymeOS ROM, according to Team Android. This firmware allows the users to fully customize their mobile device.
The term 'old' is thrown around liberally at a time when smartphones are treated to a paltry one-year life cycle. Essentially, it doesn't take long for the hottest property in tech to become old news — the Galaxy S6 and S6 edge are now precisely that as we look ahead to the seventh-coming at Unpacked
It goes without saying that many of the devices we own these days are convergent in nature – and our smartphones would be the best example to cite, taking into consideration the sheer number of tasks in which it is capable of achieving. Well, Canonical has just shown off its multi-talented BQ Aquaris M10 Ubuntu

GOLLIVER: Regular-season report cards for all 30 NBA teams
Arizona State coach Herb Sendek said via the press release that he and Carson discussed his options and decision, and wished him well:
"Jahii and I discussed his decision to enter the NBA Draft, and while our program will miss him, I know he is ready to start his professional career," said Sendek. "Jahii made an incredible impact on our program over the past two seasons and was a huge part of the success we achieved as a team. I know I speak for the entire Sun Devils community when I say we are wishing Jahii and his family all the best in the future."
The decision was expected after Carson and Sendek acknowledged his departure early last month.
Carson has been projected to be a late first-round or early second-round pick.

I am so glad you decided to continue doing these ideas. They are very enjoyable to read. Once again, I think you should definately extended some of them into oneshots.
| bbissocute chapter 2 . 11/5/2007
Yes, yes it is. Excellent job! I love this. So much fluff tucked into such a small place...So nice...
Know that we're all here for you. I know what depression can do (my mother has gotten it quite frequently, occasionally contemplating suicide) and just know if you need to talk about it, be free to talk to me. It helps. I promise.
Again, really amazing story/shot thing. I cant wait for more. And, I hate to be a bother but there seems to be an error with the program making a few of the italicized words go back on the word in front of it. Ex: "hehated" on 130. I hope I'm not over stepping my boundaries. Especially now.
Loved the story, great job, hope to hear from you soon,
| cheekylildevil chapter 2 . 11/5/2007
great job
200 was my favourite! And 147 and 154 and 168 and 183 and 196!
| Agent of the Divine One chapter 2 . 11/5/2007
Hilarious. :)
But what were you implying with 107?
| titanfan45 chapter 1 . 11/1/2007
That was different than anything I've read in fanfiction so far. I enjoyed it. Well written.
| Lvl2DragonTamer chapter 1 . 10/31/2007
Awesome story. I'm adding this to my faves, and you to my favorite author list, since I've liked just about everything I've read of yours so far.
"Million", "Relieve", "Days", "Education", "Atom", "Baffle", "Referendum", "Energy", "Forecast", "Dreaded" and a whole lot more made me laugh like crazy. "Couples" was the best, though. I can see that all too clearly X).
And then the more serious ones-"Conceal", "Bullets", "Torn", "Growth", and the best one out of all of them, "Estimates"-all of these were really incredible. I liked how you had Raven lose it and almost kill the doctor-that was really sad. I'll have to check out all of your other fics, when I have the time.
| Dreamer878 chapter 1 . 10/27/2007
I love it!
My favourites were: 12, 14, 16, 22, 27, 40, 48, 50, 58, 76.
I really was curious about most of the things you have put forward in this and I really hope you expand on some of them and make them into one-shots. I got to your profile a while back from bbissocute. I have today decided to finish off reading all your stories - I have throughly been enjoying them. Just one thing - I don't quite understand number 62. Otherwise it was awesome!
| Alonein-Darkness7 chapter 1 . 10/22/2007
My favorite five were Referendum, Inheritance, Solicitor, Design, and Talent! I'm not a StarRob fan in the least bit, but I found all of these to be really good ideas! I really love that you have a lot of these written for Cyborg. I love that guy but I'm never able to find anything written for him.
| Lambbaby chapter 1 . 10/20/2007
AH! You mentioned Cheshire! Next to Jinx she may be my new favorite bad girl...if only I can manage to work her into a fic all would well in the world.
So (please ignore my fangirl moment above) I tried to pick out a favorite...and couldn't.I loved them all, mainly because they were so different and yet so very much the Titans we know and love. If I had to choose my top...5? I'd say that #94,#87,#47,#34 and #8 were the ones that I would love to see you flesh out.
I'm beginning to think I may have to give Calli back the title she gave me and give it you instead. Of course I'll change the wording a little...unless you want to called a writer-goddess?
| Agent of the Divine One chapter 1 . 10/18/2007
Fascinating, but I don't understand 22.
Good work as usual.
| bbissocute chapter 1 . 10/15/2007
Wonderful job! I loved every one. Keep it up.
| inq101 chapter 1 . 10/15/2007
More great work, some very insightful stuff here.
(tries not to get jelous of someone elses talent)
Keep it up
| Belladonna Kyle chapter 1 . 10/14/2007
I actually really liked it, mainly becuase you could look at it anyway you want. Like 100, that could be Robin/Raven, Kid Flash/Jinx, Cyborg/Someone, you know what i mean. I espcially liked the inheritance one, because it showed just how secretive Beast-Boy . Gotta love the almost flushing Beast-Boy down the toilet one, that would have killed him. It was all rather cute.
| CalliopeMused chapter 1 . 10/14/2007
Just so you know- Kay and I blame you complete for the starfish thing. I'm on the "what the- there's no central nervous system/circulatory system/bones, how is he going to regrow a leg when it would take an echinoderm a year to begin with?" side. She was on the "image stuck in my head, a week of Rae and BB and lots of time together" camp, and still is. I'm on the side of medicine, QuikClot, paramedics, and some lucky surgeon giving Rae-darling a crash course in limb reattachment.
The debate lasted more than an hour, by IM time stamps, and I eventually drafted my roommate to support the side of "what the- he's a freaking starfish!". Knowing you, you feel absolutely horrible.
Okay, now the part of the review that's actually about the story-like-thing.
You have the strange, the disturbing, the cute, and the just plain sad. I never am sure just how to review these things, because any one of them could be a story and no twelve of them seem to be in the same timeline. I'm pretty sure I could read this two more times and catch new things, and a couple more will stick in my head and want to be longer stories.

When I first saw that episode I thought :" Well at last he made sure she has a penny for the ferryman"

Ed Morrissey is dizzy with trying to figure out which would have been worse: President Obama meaning the snub to Brown and Great Britain, or that it was apparently just a by-product of the administration's inability to run the country. Me, I'm too busy being appalled that there are supposedly functional adults in the Democratic Party that thought that saying the below would help. Read the whole thing, but only if you think that both your head and the wall will survive the pounding that you'll be giving the latter with the former:
Barack Obama 'too tired' to give proper welcome to Gordon Brown
Barack Obama's offhand approach to Gordon Brown's Washington visit last week came about because the president was facing exhaustion over America's economic crisis and is unable to focus on foreign affairs, the Sunday Telegraph has been told.
Sources close to the White House say Mr Obama and his staff have been "overwhelmed" by the economic meltdown and have voiced concerns that the new president is not getting enough rest.
Mr. President?
Man up.
You see, I don't give a tinker's dam if you're feeling overwhelmed. I could care less if your stress levels are elevated. If I came across you puking in the White House toilet from the nervous tension, my only response would be to flip the switch that turns on the fan before I went to find another bathroom. That's because you wanted this job that you now have, and if you didn't know that it was a killing job then you should have asked somebody. 2.5 years apparent aging for every one on it; that's the cost of being POTUS. A look at before-and-after pictures of Bill Clinton and George W Bush should have driven the message home for you. In short, you have no excuse, and my sympathy is zero.
So, instead of sending out people to whine for you about how you can't get your head above water, ask yourself: are you prepared to hack it anyway? If you are, then shut up and do it. If you aren't, do the country a favor and quit. God help me for saying this, but if you can't do the job give it to Joe Biden; he can't do the job either, but at least he's not too proud to beg for help.
Moe Lane
PS: Find the person who made that statement to the Telegraph, thus embarrassing the country, myself, and (least importantly) yourself. If that person works for you, fire that person. Fire that person filthy.
Right after you fire this idiot:
The real views of many in Obama administration were laid bare by a State Department official involved in planning the Brown visit, who reacted with fury when questioned by The Sunday Telegraph about why the event was so low-key.
The official dismissed any notion of the special relationship, saying: "There's nothing special about Britain. You're just the same as the other 190 countries in the world. You shouldn't expect special treatment." The apparent lack of attention to detail by the Obama administration is indicative of what many believe to be Mr Obama's determination to do too much too quickly.
Because there's going to be a post-Obama era someday, and I'd quite like there to be something to work with in it when it comes.

Looking down from the cliffs at the secluded, sandy coves below and the intense turquoise of the sea, you could be forgiven for forgetting that you're in the Ukraine. Crimea is as different from the rest of the country as can be - a slice of the exotic connected to the mainland by two tentative strands of land. Crimea's autonomy stems not just from the peninsula's physical distance from the mother country, but also from its unique history, having been shaped by the Greeks, Romans, Mongols, Ottoman Turks and Crimean Tatars, in contrast to the far more homogenous mainland. Today, Crimea is becoming more and more popular with visiting Europeans, as well as the usual contingent of Ukrainians and Russians.
Stretching from remote Yevpatoria in the west to Feodosiya in the east, the Crimean coast includes both busy seaside resorts and quiet villages, each with its own distinct character. Images of sand-strewn sun worshippers, well-dressed holidaymakers sipping sweet Massandra wine in seaside cafés and millionaires' yachts bobbing on the water are particularly true for the south coast - a lovely but busy stretch of white-sand beach lined with upmarket resorts and exclusive spas running between the tourist hubs of Yalta and Alushta. In contrast, the coast running west from Yalta to Foros is less developed, and dotted with secluded coves, fishing villages and low-key holiday cabins. Inland, mountain-bikers and hikers are making inroads into the little-explored and dramatic mountainous terrain.
The towns of Yalta and Alushta are the south coast's most popular resorts, and the ones that best epitomise the classic image of Crimea as an elite summer retreat for Russian nobility. Yalta's own whitewashed, Renaissance-style Livadia Palace was originally the summer residence of Tsar Nicholas II, and was later used to host the 1945 Yalta Conference between the Allied leaders of WWII. Wistful photographic exhibits on display here are dedicated to Russia's last royal family.
Yalta offers the greatest range of accommodation, from upgraded Soviet-style sanatoriums such as Dnepr - complete with available medical check-ups and treatments - to atmospheric luxury hotels such as Oreanda and Bristol. The eating scene is appropriately diverse, featuring cafés dotting the seafront; elegant fine dining, such as Byely Lyev (Nab Lenina 31A) and Oreanda, which specialise in European and Ukrainian haute cuisine; beachfront shashlyk stands grilling up succulent skewers of meat kebabs; and teahouses such as Aishe (Nab Lenina 9) serving plov (rice with lamb), a dish reflecting Crimea's Tatar heritage. The beachfront revelry continues late into the night at laid-back cocktail bars such as Apelsin (Nab Lenina 35a) and Mojito (Nab Lenina 32), and at the 24-hour dance clubs: Matrix (Nab Lenina 35/2) has nightly performances from international DJs (and a strict dress code).
Alushta is greener and less crowded than Yalta, and home to excellent modern spa hotels, such as More, which offer multiday revitalisation treatment packages by day and lively seafront discos by night.
Quiet Yevpatoria specialises in health tourism, with a smattering of sanatoriums, hot springs and mud treatments that allegedly possess curative properties. Apart from its upgraded facilities, it seems little changed from the time when Soviet workers and their families were sent on seaside holidays here as job-performance rewards. Well-equipped health resorts such as Planeta epitomise Yevpatoria's relaxed, child-friendly character.
Though many come to Crimea for the beaches, there's plenty more to entice you away from the sea. Near Yalta, a short hiking trail leads to Uchan-Su, Europe's highest waterfall. Just south of Yalta, Cape Ai-Todor is home to the much-photographed Swallow's Nest Castle, perched on the very edge of a steep cliff and offering stupendous views from the top. Crimea's 'Grand Canyon' - the gorge between Yalta and Bakhchisarai - makes for some wonderful trekking, particularly if you follow the trail down into the gorge and take a dip in the little waterfalls created by the Auzen-Uzen River. The summit of Ai-Petri, a mountain towering above the tiny town of Alupka, offers splendid views of the Crimean coast; it can be reached by rickety cable car or - for the fitness lovers - by mountain bike.
Alushta makes an excellent base for exploring the nearby Byzantine and Genoese castle ruins. You can also go on guided hikes into the Crimean Nature Reserve, home to gazelles, mountain goats, foxes and numerous bird species. Other spectacular outdoor activities include trekking, mountain-biking, horse riding and camping on nearby Demerdzhi mountain, which offers an otherworldly rock-sculpture garden called the Valley of Ghosts, the majestic Dzhur-Dzhur waterfall and dizzying views from the summit.
Inland, near the regional capital of Simferopol, lie several cave formations. Eminé-Ba'ir-Khosar was the scene of the tragic story of a maiden who threw herself into its incredible 120m (393ft) depths when her love was killed by her father's tribe. Mramornaya (Marble) Cave, a 60,000-year old subterranean riverbed, attracts cavers with its 'melting' rock formations and the opportunity to explore its untouched lower depths with a hard hat and torch.
Sevastopol, a port formerly closed to foreigners, boasts the lion's share of historical monuments. Aficionados of the Crimean War can head south to Balaklava; the valley above it was the site of the ill-fated Charge of the Light Brigade. The Sevastopol Diorama offers the best panoramic view of the former battle site, now an attractive meadow with some vineyards. The town itself is home to Chersonesus, Crimea's largest and most intact Greek ruins; they go right down to the seafront, allowing you to combine a stroll amidst intact temples with a swim, or even a dive in search of treasure with Akvamarin.
The living presence of Crimea's ancient Tatar culture is felt particularly strongly inland, in Bakhchysaray, once capital of the Crimean khanate, where Tatar grandmothers sell traditional food such as köbete (meatballs) and hearty lagman (noodle soup). Here you can visit the 16th-century Khan's Palace and wander through the harem and courtyards, admiring the lofty minarets, the Fountain Yard, the elegant calligraphy above the doorways and the interior of the working mosque.

ONE would be hard pressed to find a government that would say it likes the press or enjoys the kind of scrutiny the press subjects it to. Yet it is equally difficult to find a democracy that is attempting to emasculate the media in the manner in which the South African government is doing with the Protection of Information Bill and the punitive media tribunal it wants to introduce. And although SA is not alone in fighting the free flow of information, it stands out as a country that is sliding backwards at a fast pace in its bid to make public information its own private property.
Consider some of the defining features of authoritarian tendencies in media law, which London-based author and academic Tim Crook writes about in his latest book, Comparative Media Law and Ethics.
A jurisdiction that leans towards authoritarianism practis es "absolute or near total secrecy and suppression of all information relating to intelligence, police". Its "free- speech rights are qualified by rights of national security".
It doesn't believe in "guaranteeing public access to information collected and stored by government/state bodies".
It is a country that imposes "criminal liability on private citizens and journalists who received state information where the classification of confidentiality and secrecy is broad and all-encompassing".
And there's more. Its "ruling elite" buys into the media market "to silence and discourage critical reporting". It's a place where "heavy penalties" are handed down to journalists who "try to protect their sources".
It is also a country that grants "wide powers for state agencies to tap communications of journalists and collect surveillance evidence for the purposes of identifying their sources" and practices "overt and covert . attacks on journalists working for media institutions that publish critical coverage".
If all that sounds familiar, it's because it reads as if it was lifted chapter and verse from the latest government proposals.
The sad feature of Crook's work, however, is that while SA sits firmly in the libertarian camp today, it will find itself lumped on the authoritarian side of the fence tomorrow if the government succeeds in clamping down on freedom of expression.
The other alarming fact, though, is that the South African proposals are the best kept secret in the international arena of media law experts, anticensorship groups or institutions that protect the purveyors of information themselves. When the draft bill was circulated last week among experts in Canada, Israel, the UK and the US, their reactions were not surprising.
"The proposed bill is draconian," says Mibi Moser, a renowned media lawyer in Israel, where limitations on the media are already stringent because of the country's geopolitics and the constant tension between the military and the executive. In comparing the South African bill and current Israeli legislation, he highlights SA's broad definition of "state information", as well as the reasons for not disclosing such information as enormous causes for concern.
Israeli law puts the emphasis on the right of the Israeli citizen to have access to public information, he points out. But the emphasis in the South African instance is the reverse "and it is frightening". But "the most arousing cause for concern", in his appraisal, are the proposed "severe penalties for obtaining, collecting, capturing or copying all kinds of 'state information'."
It's a view echoed by Prof Klaus Pohle, a media law specialist at Canada's Carleton University. "This is something you might expect in a totalitarian banana republic," he argues. However, it's the arbitrarily defined terms of "public good" and "national interest" that unsettle Pohle most. While Pohle concedes that most western democracies - Canada included - have legislation that errs on the side of national security, which is often poorly defined, it is never "as ill defined as (SA's) description of the national interest".
"Among the enumeration of what is meant by the national interest is the public good", which is "vague and subjective.. This section should be the most worrying since it can include anything," he says. "Any criticism of public policy, governmental activity or even private commercial activity may be seen as an attack on the public good."
Imagine trying to debate the previous South African government's so-called AIDS denialism under the proposed legislation, he suggests. It just wouldn't wash because it would be undoubtedly seen as an attack on the public good. But would silence then have been helpful? Surely not.
Or take the example of the Gulf of Mexico oil spill. Had it happened in SA, "one could easily assume that assigning blame, however much warranted, may not serve the public good because it might disturb relations between the developer and the state" under the proposed bill, he points out.
"It might even be illegal to discuss critically the contents of this very bill," he says. Or the arrest of Sunday Times journalist Mzilikazi wa Afrika, for that matter. Not to mention corruption on the part of public servants and government officials. Or the lack of service delivery. The list goes on.
But the question that rolled off most tongues was why SA would want to go down this route at this time.
The answer is quite simple. Our political elite is feeling very insecure and threatened, not by a lack of security, but by what the free flow of information might do to their ever- closing political system, and so has decided to drag the young democracy in the direction of such countries as China, Saudi Arabia, Venezuela and Russia.
Joel Simon of the New York-based Committee to Protect Journalists says governments everywhere are becoming more sophisticated about the strategies they use to control the media.
"Increasingly, legal pressure, advertising boycotts, punitive tax raids, libel suits and other less visible means are replacing imprisonment and state-sanctioned violence," he says.
This is true of China, where a journalist is more likely to be fired than jailed for critical reporting, he says. "And in nominally more open countries, such as Russia, where the Kremlin has used tax raids to take over critical media outlets."
(In SA, it seems, the preferred practice is still arrest.)
Simon balks at the proposed media tribunal, which he sees as a pathetic attempt to control criticism and dissent.
Yet if the litmus test of real political authority and power is the ability to withstand criticism, then why doesn't "the African National Congress (ANC) muster the maturity and the courage that is required to lead without resorting to these kinds of measures?" Crooks asks. "Don't they see that they would also amass a considerable amount of power in the world if they did?"
Clearly not. Instead, the ANC is about to dispose of all the political dignity it has left.
For the past few years, SA has found itself languishing among the flawed democracies of the world in the index of democracies compiled by The Economist's Intelligence Unit (EIU), scoring just shy of what is required to join the world's full democracies.
It was hoped that this year SA would crawl up into the category of the world's best.
"But if these media proposals become practice, SA will be downgraded, not upgraded," says Pratibha Thaker, regional director of the EIU's Africa department.

What does DVR Ready and PVR Ready Mean?
This article explains exactly what DVR Ready and PVR Ready means on your new High Definition TV or Set Top Box.
Would you like to record your favourite TV shows?
Record Live TV?
Perhaps you want to go one step further with the ability to pause and rewind live TV?
Ah, the convenience of being able to watch your shows at your own leisure, and fast forward those annoying ads!
Well, that is exactly what a TV that is DVR / PVR Ready will allow you to do! These days they call it Direct USB Record.
So all you need with your DVR/PVR Ready TV is a PVR Machine.
Just hook up your PVR Machine to your TV and bang you now can Pause and rewind live TV, and in some cases you can even record 2 shows on different channels at the same time. This is an awesome feature to have when you have a pesky visitor interrupt you during your favourite show!
To put it simply DVR stands for Digital Video Recorder, and PVR stands for Personal Video Recorder.
You could rent a PVR which has an inbuilt dual High Definition Digital tuner, that is, 2 TV tuners. Which means that you can record 2 programs at the one time, whilst watching another program. You can also pause and rewind live TV. Its great, almost like the Foxtel box for free to air TV!
This is the best way to take advantage of all those new free to air, freeview TV channels!
Now we must mention, you can use a portable USB hard disk drive to record your shows, which can be a much cheaper option, but before you go out purchasing a hard drive, be sure to check the user manual for your TV to ensure you get the right one! For instance, LG Smart TVs or Interactive TVs require the portable hard drive to have its own power supply and be at least 40GB. This is why we recommend using a PVR Machine, as you will know it will work. You will be able to pause/rewind Live TV, record 2 shows at the same time, use the planner to set up your PVR machine to record your shows on a regular basis – even when your not home.
You will never have to watch ads again, and will always have something to watch with a PVR Machine. So why not rent one with your TV today!

"Real trade - TEX was $23.30, and I sold the ONE month $24s at 80 cents. So I took a FOR SURE 3.4% for the month, and still had 70 cents upside. I've traded the calls, but if I hadn't, OK, I'd have 6 cents I left on the table so far.
But I received an immediate 3.4% for the MONTH, and have gained another 3%. 6.4% in a month, compound that?, I'll take it. If TEX goes, and STAYS at $40 over the next two weeks, oh well, I blew it."
Seems like you may have blown it this month. The whole point isn't how much you make month to month its about the 1 in 4/5 months where you really blow it. You have essentially capped all your upside and are betting the stock will be flat. Why even invest.
"Why even invest?"
To make money? Hope you're just advocating a point, and not trying to start a #$%$ contest. Because over the year and a half, TEX has gone up a grand total of NOTHING...... it's the same price it was in MAY of 2011. Go back a couple of months, and it's DOWN 25 - 30%.
And all that time, the option premiums crank out about 3% a month. As I said, different folks, different strokes. (I take for granted you are experienced enough to understand the options aren't locked in, one can roll them at any time.)
As far as today goes, I told you at the start that I hadn't locked in the ones you quoted me on.... at this exact moment, I've captured all but 20 cents of this move, and all the while had the 3.4% in my pocket if the stock had stayed flat.
Sorry, James. While you are eventually going to be correct on this stock, the eventually part is starting to eat at your ROR. At least to the point where I don't think you can make the argument that buy and hold is the ONLY way to go.
Buy and Hold with TEX is going to make great money. But so can trading it, and so can covered writes.
It is all perspective and when you pick the starting day. Since May 2011 the stock may be be flat but its up 100% this year. So buying when it goes down is far more lucrative then the call strategy.
So you wrote real trade but it isn't? So what was your exact trade then.
I am just pointing our the flaw in selling calls. You hold and own a stock for it to go up. Selling covered calls caps your upside and barely limits your downside for a locked in premium.
My point was why invest in a company if you're going to bet every month its going to be flat. If it goes down you share in all the downside save the premium you saved and if it goes up you lose the money you could have made. To me selling covered calls in this case isn't good. Obviously Ill go case by case since sometimes the premium may be large enough to warrant. 3.4% isn't enough.
It is all perspective. since may 2011 it may be flat but its up 100% this year. So buying when it goes down us far lucrative.
So you wrote real trade but it isn't? So what was your exact trade then. My point was why investthen cap yyour gains nut barely limit your downside. Its silly to me. The 3% is an illusion since it will move enough times that it makes it unprofitable.
Its not buy and hold its buy hold and buy some more

Form.ControlCollection.Add Method
Assembly: System.Windows.Forms (in system.windows.forms.dll)
|Exception type
A multiple document interface (MDI) parent form cannot have controls added to it.
You can use this method to add controls to the form. If you want to add a group of already created controls to the form, use the Control.ControlCollection.AddRange method of the Control.ControlCollection class.
The following code example adds a TextBox and Label control to the control collection of a form. The example requires that a form has been created and named Form1.
