Why are there convoluted foam panels behind your screens Mikk? They don't make any sound
They're there to protect the screens when I get mad and throw them at the wall
No actually I used to have two screens and the speakers were in front of the outermost foam panels. The one on the center was obviously where I sit just to remove flutter echo from between the front and back wall. The screens used to be lower too, below ear level. I suppose the panels aren't thet effective anymore but I just left them as they were.
Very nice Mikk!
Great speakers by the way. I've got the same ones
Like Progressive and Deep House? Grab my latest mix below

I used Genelecs on another studio few days ago where we recorded vocals for my friends project. While they're very accurate monitors too, long sessions with even moderate volumes aren't funny. I'm happy with the Dynaudios
Hi Mikk,
oh shit!
Your JP-8000 is curved in it plastic chassis? Mine too!
JP-8000 is an original banana synth!!
This problem is very ridiculous! another problem is the clicks in attak

I am in the process of building my oven. I have been dreaming of a pizza slice where the crust will have a slight crunch on the outside and a moist dough on the inside. I imagined being able to hold the slice by the end crust and have the slice stand out straight as I eat it. Tonight I went to a local pizza restaurant that had a WFO. Cool to see....however, the pizza crust was not the way I expected. It was very limp and not crunchy at all. In fact, I had a hard time eating it without a fork. My question is....is this normal? Do I have expectations of the WFO that are unrealistic or is it just a bad restaurant?

Re: limp pizza dough
It depends upon what type of dough you make and how long you cook it. For what you had at the restaurant, it was probably a 24 hour warm rise and the 60-90 second cook. For the pizza you want, you will probably want a 24-48 hour cool rise and a 2-3 minute cook.
Re: limp pizza dough
Curious which Pizzeria you were at? There is one in Metro Detroit doing fairly authentic Neapolitan that is pretty wet and floppy like it should be. Most of the others do what I call americanized neapolitan that is dryer and crisper.
I agree with Tom, a wood fired oven is a versatile beast. You an cook what you want, it will just be done at a lower temperature and longer back time than traditional Neapolitan pizza.
Re: limp pizza dough
I'll tell you what has worked well for me. I find I get my 'desired' result, which is close to what you describe, when the dome is hot but the floor is 'moderately hot' allowing the floor to cook a bit longer and get a little drier/crisper. Of course, the life fire gets you the right spring for the desired crust, so the top will be done before the bottom....but I simply hold my larger metal pizza peel over the top for 45 sec or a minute to keep it from getting overdone while the crust on the bottom reaches my ideal spot.
Fired up yesterday, here's my personal favorite. I julienne pepperoni and pan fry it to intensify the flavor. That and some nice sweet sausage, bought with no casing. I have this as my wall paper on my computer and my mouth waters everytime I use the pc!

Dakota maid, all trumps, or king Arthur all make this type of flour.
Do a couple of stretch and folds to the dough midway and cook at a 700-800 degree oven and it will come out great.
Re: limp pizza dough
I'm really surprised to hear it was Tivoli's. I enjoy their pizza, but it is much more New York then Neapolitan, and I've never had anything wet there in many trips. I'd guess Tivoli's is about a 4-5 minute bake time with a high gluten flour and dry mozz.
To get a result as dry as you want you are gonna need to use a fairly low hydration(maybe 55%, not really sure), a dry mozz, and an oven running much cooler then normal, I would start around 600F.
The only downside is that in all honesty what you are after could easily be cooked in a home oven. The upside to that is you could start dialing in your dough now. I'd head over to pizzamaking.com and get some advice on making what you are after from people who have done it.
Re: limp pizza dough
I appreciate all the feedback. Especially the part about being able to do it in a tradition home oven....I'm sure it was a bit hard to tell the guy that just invested thousands of dollars and countless man hours to something that he could have done with what he already owned. But I appreciate you telling me that. I think WFO cooking will teach me alot......has already! This post is just one example. You are probably correct about Tivoli's....they offered a thin crust (which is what I got) that is cooked in the brick oven. They also offered a NY style which was cooked in a gas oven. Sounds like I picked the wrong one for what I was looking for. Now that I know the difference I will have to investigate the two methods. I like them both and it would be fun to be able to have different styles....although I think I like the crunchy style best at the moment. I am learning more every day that this oven is not a one trick pony....which is awesome.
Re: limp pizza dough
No matter what, having a wood fired oven is always better then not having one, you are gonna love it. I'm also gonna bet that if you get really in to pizza you will eventually branch out into different style, some of which the wood fired oven will be a huge plus for due to the extreme heat it can produce.
Just for clarity my statements on Tivoli's were based on their thin crust wood fired pizza, only thing I've ever had there. Like I said before it is much closer to New York then Neapolitan. I would bet their New York style is actually closer to a standard american style pizza then actual New York style. Pizza style classifications can get pretty complicated, and like most pizzeria operators I don't think the people at Tivoli's really care about using the proper names, just the names that sell. Most are in the money business, not the pizza business.
Re: limp pizza dough
Hi Try using 00 Caputo flour its wonderful and should produce a light crispy crust.Caputo Pizzeria Flour 55 lb. :: Tipo 00 Pizza Flour :: Forno Bravo Store
Re: limp pizza dough
I personally would not use caputo for what you are after. Caputo is unmalted, and as such is intended for high temperature bakes. Using Caputo for what you are after will probably lead to browning issues. An american malted flour will not only be cheaper and locally available, but it will give a better result.
If you want to try Caputo regardless, or for a different style pizza you can get in a few places in the metro area.

General Note: The International Conference on Multiphase Flow (ICMF) first was held in Tsukuba, Japan in 1991 and the second ICMF took place in Kyoto, Japan in 1995. During this conference, it was decided to establish an International Governing Board which oversees the major aspects of the conference and makes decisions about future conference locations. Due to the great importance of the field, it was furthermore decided to hold the conference every three years successively in Asia including Australia, Europe including Africa, Russia and the Near East and America. Hence, ICMF 1998 was held in Lyon, France, ICMF 2001 in New Orleans, USA, ICMF 2004 in Yokohama, Japan, and ICMF 2007 in Leipzig, Germany. ICMF-2010 is devoted to all aspects of Multiphase Flow. Researchers from all over the world gathered in order to introduce their recent advances in the field and thereby promote the exchange of new ideas, results and techniques. The conference is a key event in Multiphase Flow and supports the advancement of science in this very important field. The major research topics relevant for the conference are as follows: Bio-Fluid Dynamics; Boiling; Bubbly Flows; Cavitation; Colloidal and Suspension Dynamics; Collision, Agglomeration and Breakup; Computational Techniques for Multiphase Flows; Droplet Flows; Environmental and Geophysical Flows; Experimental Methods for Multiphase Flows; Fluidized and Circulating Fluidized Beds; Fluid Structure Interactions; Granular Media; Industrial Applications; Instabilities; Interfacial Flows; Micro and Nano-Scale Multiphase Flows; Microgravity in Two-Phase Flow; Multiphase Flows with Heat and Mass Transfer; Non-Newtonian Multiphase Flows; Particle-Laden Flows; Particle, Bubble and Drop Dynamics; Reactive Multiphase Flows Record Information Bibliographic ID: UF00102023 Volume ID: VID00362 Source Institution: University of Florida Holding Location: University of Florida Rights Management: All rights reserved by the source institution and holding location.

Coal is the only fossil fuel with a reserve of more than 100 years at current production. Compared to coal, oil and gas reserves are in the order of 40 and 60 years. There- fore, it is expected that coal will remain a primary en- ergy source in the next years. One opportunity to use the coal more efficiently in power stations is to apply gasi- fication technology. In an Integrated GI.silk~.lil al Com- bined Cycle (IGCC) an upstream gasifier produces syn- gas from coal, which drives a high efficient combined cycle. Furthermore, when it comes to reducing CO,- emissions from power plants, the IGCC technology of- fers favorable conditions for the implementation of Car- bon Capture Storage (CCS) by means of CO-shift and CO,-separation in front of the syngas combustion. Be- yond this, the syngas can be used as feedstock to substi- tute natural gas and liquid fuels as well as for hydrogen production. The research work in this paper is focused on mod- eling and simulating a high pressurized entrained-flow coal gasifier using the commercial CFD code FLUENT 6.3.26. In the gasification process coal is gasified at high temperature and pressure with Og and HO. For a bet- ter understanding of the flow pattern and the gasifica- tion process a reaction mechanism have been used for the volatile pyrolysis, heterogeneous and gas phase re- actions . The first step of the work is to simulate an entrained- flow gasifier in a combustion environment. For this pur- pose the coal input has been reduced and the amount of H,0OIO mixture has been adapted to reach hyperstoi- chiometric conditions. In the second step the simulation of the gasifier has been switched to substoichiometric conditions. The main results of this study will be shown and discussed. Based on this, the influence of the swirl number on the species concentrations within the gasifier has been ex- amined. In this work the swirl number S is defined as the ratio of the tangential component to the axial component of the velocity. The influence of the mixing intensity on the gasification behavior has been analized with varia- tion of the swirl number. This takes also an effect on the heat transfer in the reactor and therefore on the gas out- let temperature and the cooling capacity of the reactor. In the simulation the wall temperature of the reactor is kept constant which is a simplification of the real pro- cess. However, first tendencies of the interactions have been identified. Future work will focus on the extension of the simulation model for example by a slag formation submodel. 2 Mathematical Modeling The steady-state Reynolds average Navier-Stokes (R,4NS) equations are used to model the entrained- flow gasifier. The continuous gas phase conservation equations include the equations for continuity, momen- tum and energy. 7th International Conference on Multiphase Flow, ICMF 2010, Tampa, FL, May 30 June 4, 2010 to close the equations. This turbulence model is a recent development and differs from the standard k t model in two important ways. First, it contains a new formu- lation for the turbulent viscosity by computing the value C,,. Second, a new transport equation for the dissipa- tion rate has been derived from an exact equation for the transport of the mean-square vorticity fluctuation. The following equations are used to calculate the reynolds stresses: "(p i)3 [( p,I <0 r +~ (pu; = p are } zr A (4) (Pe i) ui ri -(~ dz + + pC'Se kC~ + ~tCltb The turbulent viscosity is calculated by pt = pC,,k /t. (6) The terms SI, and S, are user defined functions. The values of aex, a,, C1, C2, C1e, Cse and the equation for C,, are given in (7). GA and ab represent the generation of turbulence kinetic energy due to the mean velocity gradients and to buoy- ancy. a~b -*/ ?) _i~ = 2.1 Particle transport equation The coal particles are assumed to be spherical and de- scribed with the Lagrangian equations. The governing equation for a particle trajectory (in x-direction) is: The first term on the right side is the drag force and the second term is the buoyancy force per unit particle mass. Fx is an additional acceleration (force unit par- ticle mass) term, e.g. thermophoretic force, Brownian force, and Saffma's lift force.

The only unknown term is the Reynolds stress -'-' Because this set of equa- tions is not closed the realizable k t model is used 7th International Conference on Multiphase Flow, ICMF 2010, Tampa, FL, May 30 June 4, 2010 2.2 Heat Transfer In this work the conductive, convective and radiative heat transfer are taken into account between the gas, par- ticles and walls. The isotropic scattering properties of the particles to radiation are assumed and the P-1 radia- tion model is used to describe the radiative heat transfer as: Q -V (11) 3 (ag + ap + os ) where a, and a, are absorption coefficients of gas and particle and os the scattering coefficient respectivley. 2.3 Reaction Mechanisms In this study three reactions are included for the gasifica- tion process: (i) coal devolatilization and volatile pyrol- ysis, (ii) heterogeneous char particle surface reactions and (iii) homogenous gas reactions. 2.3.1 Coal devolatilization and volatile pyrolysis The coal devolatilization process is calculated by the two competing rates (Kobayashi) model: x? y z O :CO + -H20+ aN, 2 2 CO + 1/2 O, CO, 2.3.2 Heterogeneous char particle surface reactions Three global heterogeneous reactions according to (4) are used for the char gasification process: C(s)+ +O, CO, C(s) + CO, a 2CO C(s) + HO 4 CO + H, For each reaction the total reaction rate is determined by diffusion and the intrinsic chemical reaction rate. The reaction rate Ri of ith reaction can be expressed as: 4 R ,4, (20) Di + Ri,rc , where Rossi, is the kinetic rate of reaction and Di is the diffusion rate coefficient of the reaction. The diffu- sion rate Di is calculated by D= ,:lT 0 :)30 7 (21) where C, is the diffusion rate coefficient of the its reactant, T, the absolute particle temperature, T, the ab- solute gas temperature and d, the particle diameter. The apparent chemical reaction rate Rigs, is calculated by the new empirical reaction model. Ri,rcin = Agexp RT 10 6 (22) The preexponential factor A and the activation energy E for each reaction are taken from Chen (2) and is listed in table 1.

The two kinetic rates are weighted to yield an expression for the devolatilization as: m, (t) _ (1 fw,o) mp,o me t (0121 + agR,,,, ~i,,~) ep R +2)dii o a (14) where m,(t) is the volatile yield up to time t, mp,o is the initial particle mass at injection and m, is the ash content in coal particle. The variables at and as are yield factors. A two step reaction mechanism is used for the volatile pyrolysis. The term OxHOzN, is calculated with the proximate analysis, ultimate analysis. The enthalpy of formation of the volatiles is based on their lower heating value. The two step reaction mechanism can be written according to (6) as: 2.3.3 Homogenous gas phase reactions The following reaction mechanism is used to describe the gas phase chemistry.

Reactions proceed over the calculated time scales governed by Arrhenius rates and are integrated numeri- cally using the In Situ Adaptive Tabulation (ISAT) algo- rithm (12). ISAT is a powerful tool that enables realistic chemistry to be incorporated in multi-dimensional flow simulations by accelerating chemistry calculations. In full, the method is: in situ, unstructured, adaptive tab- ulation of the accessed region with control of retrieval errors (12). In order to use a tabulation method for a particular flow, it is sufficient to tabulate the accessed region, rather than the whole of the realizable region which is much larger. Since the access region depends on many aspects of the flow, it is not known prior to the performance of the calculation. Hence the table is built up during the reactive flow calculation. Each entry in the table corresponds to a composition that occurs in the calculation. This is referred to as in situ tabulation. 3 Problem description and numerical settings In this paper a 2D axisymmetric model is used due to the symmetry of the gasifier. A cross section of the entrained-flow gasifier is given in Figure 1. Coal will be gasified under high temperature and pressure with Og and He O. Molten slag builds a protection layer for the cooled wall. The temperature of the liquid slag should be controlled in a small range. The CFD simulation of combustion processes is well studied and a lot of research work is published (13). In the past years only a few CFD simulations of gasification processes were performed and a great need for theoretical studies is required. In the gasification process a valuable and usable syngas will be generated. A usable syngas means a high amount of CO and Hg and less CO,. By innovative conversion processes the syngas can be converted to a product gas which can be used in different ways. The purpose of a combustion process is to burn solid fuels to make use of the heat only. In the first part an entrained-flow gasifier is calculated at hyperstoichiometric condition by means a combustion process. For this an adopted amount of HO/O, is fed in the gasifier to reach combustion conditions. This C,H2, 2 + nHO nOO + (2n + 1) H, (25) CO + HO CO, + H, (26) The reactions 23 to 26 are based on the four-step re- action mechanism by Jones and Lindstedt (3) with the following modifications: for the reactions 23 and 25 the equations are build for n 1 a backward reaction for 24 is not used, but for the reaction 25. These modifi- cations are made to reach a similar reaction mechanism like (1) who describe gas phase reactions which is typ- ical for gasification processes. This four-step reaction mechanism is also usually used by simulation gasifica- tion processes [(8), (9), (10)]. The kinetic rate k is computed using the Arrhenius ex- pression: k = ATnexp (E/RT) (27) where A is the preexponential factor, n the tempera- ture exponent, E is the activation energy and R is the uni- versal constant. For equations 23 to 26 the kinetic data are based on the reaction scheme by Jones and Lindstedt (3). For the backward reactions of the equations 25 and 26 the kinetic data are calculated by equilibrium con- stants. The kinetic data for the reaction of the equation 16 is taken from Westbrook and Dryer (5). Turbulence-chemistry interactions are taken into ac- count by using the Eddy Dissipation Concept (EDC) model (11). EDC is an extension of the Eddy Dissipa- tion model to include detailed chemical mechanisms in turbulent flows. It assumes that reaction occurs in small turbulent structures, called the fine scales. The length fraction of the fine scales, y is modeled as: ? = 2.1337 kB : 00 Re"4' where the volume fraction constant is 2.1337 and a represents the kinematic viscosity. Species are assumed to react in the fine structures over a time scale 7, which is proportional to the Kolmogorov time scale.

In both processes adopted mixtures of H,0OIO have been assumed to simulate hyperstoichiometric and sub- stoichiometric conditions, respectively.

In terms of the gasification process at substiochiometric conditions the reaction mechanisms has been extended. In this case all reactions listed in section 2.3 have been taken into account. The equilibrium of the combustion reactions are clearly on the right side (CO,, H,0). For a gasification process the equilibriums of reaction mechanisms are not clearly on one side as indicated in the equations 25 and 26. This makes a simulation of a gasifier difficult and therefore two cases are studied to approach the simulation of an entrained-flow gasifier. GI.lsilk~.Ililln as a very complex process is influenced by many parameters. As a start of a better understanding of the gasification process the influence of the swirl number on the gasification behaviour has been studied. The SIMPLE method is used to couple the pressure and velocity. For spatial discretization of the convective term the second order upwind scheme is selected. A converged result has been obtained when the residuals of mass are smaller than 10-3, for energy smaller than 10-" and for turbulent momentum, turbulent kinetic energy and dissipation rate smaller than 10- Fuel Burner Pressure. water outlet t Cooling screen~ Pressure. water Inlet ) Quench p water I'0. 0.2 Hil 0.0, Cooling jacket - Gas outlet W1~aeter Figure 2: Comparison of CO2 concentration for gasifi- cation (top) and combustion (bottom) Figure 3 shows the CO concentration distribution in- side the gasifier for gasification and combustion process. For gasification the CO, concentration increases near the burner, but decreases towards the outlet whereas the CO concentration increases. For the combustion pro- cess the opposite characteristic can be observed. It is clear that the results of the combustion process are not realistic and are only made to prove the simulation for gasification conditions. However, the comparison of these two cases shows that with reducing the amount of O, the species distribution and the values at the outlet of the reactor are reasonable for a gasification process. 1 Granulated slag Figure 1: Example for an entrained-flow gasifier In all cases the simulations are in a steady-state con- dition.

Figure 4 shows the velocity distribution within the gasi- fier for the two swirl numbers. It can be seen that the velocity near the burner increases from the lower to the higher swirl number. However, the orientation of the ve- locity jet depends on the swirl number. The smaller the swirl number the more the velocity jet is orientated to the centreline. This has a high effect on the temperature and species concentration distributions. Another effect is the residence time and with this, the mixing effect of the gas mixture. 1.0.

The species concentration distribution within the gasifier for as, CO and He is confirmed in Figures 6 to 8. The amount of ag for S 17 ".' .~ is very low at the centreline so that a high mixing leads to a faster consumption of O,. For the ref- erence swirl number of S 11 II l' the total consumption of GO is a little bit later. The as distribution has a influ- ence on the species distribution on the top of the gasifier. The species profiles of CO and He are different near the burner for the both cases, but they get almost equal to- ward to the outlet. 0.6 7th International Conference on Multiphase Flow, ICMF 2010, Tampa, FL, May 30 June 4, 2010 --02 H2 ---CO -Temperature 0.4 Figure 7: CO profile for S 17 .~' (bottom) 11II I' (top) and S 0.6 04 0.2, Figure 8: H~ profile for S = 11II I' (top) and S= 17 .~ (bottom) Figure 9 shows the curves of selected species con- centrations and temperature over the centreline of the gasifier, which are in line with the results from the Fig- ures 6, 7 and 8. For the case of the high swirl num- ber (S 17 l' .' I the almost quasi constant curves of the species concentrations and temperature toward to outlet shows that the reactions of the gas mixture reached their equilibrium. The case for the reference swirl number shows that the mixing effect is still well appropriate to guarantee the total consumption of ag within the upper area of the entrained-flow gasifier. The species concen- trations and temperature have also an almost quasi con- stant curve towards the outlet. Table 3 shows the average molar concentrations and temperature of selected species at the outlet of the gasi- fier. The species concentration for the cases are almost the same.

However, the reference case has a more even temperature profile near the wall. This means the chosen design of the Siemens Fuel Gasifica- tion reactor is the optimum of a good gasification pro- cess in combination with minimized wearing and long operating times. 5 Conclusion In this paper, the reaction mechanims for the simulation of an entrained-flow gasifier is confirmed by comparison of a case where the gasifier is calculated at hyperstoi- chiometric and substoichiometric conditions. The first case was called as a combustion process because only combustion reactions was taken into account. An op- posite species concentration distribution within the re- actor and species values at the outlet are the results of these study. Reasonable results for gasification condi- tions could be shown by the transition from the hyper- to the substoichiometric condition. With this the used reaction mechanisms for the entrained-flow gasifier was confirmed. It could be observed that the swirl number has a high in- fluence on the temperature, species concentration distri- bution, cooling capacity and slag formation on the wall. The residence time of the gas mixture is high for the case of S 17 ".'i with the result that the reactions reach a quasi equilibrium condition immediately. The high tem- perature is orientated outwards at the upper part. For the reference case the swirl number is appropriate to gener- ate a sufficiently high mixing effect to obtain equlibrium conditions at the reactor outlet. The high temperature is orientated more to the centreline. Compared to the case of S = 17 ".' the temperature profile near the wall is more even at the case of S = 1II II'. which is important for a homogeneous slag flow along the reactor wall. The above results show that the case with the refer- ence swirl number is a optimized design for the gasifier. The outcomes of the 2D OFD modeling of a Siemens entrained-flow gasifier have confirmed the quality of the chosen design, which meets both targets of a good gasi- fication process as well as long standing operation times. Further analysis should be the cooling capacity and slag formation on the wall.

Tutorial for
Segments 001 - 003, 039
Puzzle Variations
Using Puzzles
These frameworks can be used to illustrate pieces of a whole. Puzzles also imply interdependence. They can be used as an alternative to a pie chart in some instances. Use these frameworks with others or alone. The size of the segments are designed to hold the maximum amount of text or content. Use them as a finished puzzle or as pieces (just move the pieces out of their position to give the appearance of random piece layout by simply deconstructing the puzzle and scattering the pieces).
Customizing the Puzzles
Adjust size
If you want to change the size/shape of the PowerFramework, be sure to hold the shift key down while sizing so that the puzzles stay uniform and scale correctly. If you are using more than one framework in these series, import them all and then size them all at once. This way they stay uniformly sized and shaped from page to page.
Color variations
Select color from your document's color palette or a complimentary color so that the PowerFramework will reflect the color scheme of the rest of your document. Do not eliminate the lines unless the pieces are different colors.
PowerPoint 2007 and 2010 options
The bevels create an effect much like real puzzles. The bevels add volume to the puzzle pieces without a layering problem. This is the best option for these frameworks.
Click here to go to the FAQ that explains a good bevel format for your puzzle pieces.
3D variations
3D doesn't work with these frameworks.
Shadows don't work with these frameworks.
Gradients, patterns, and pictures
Gradients can be used to create a distinction between the pieces. The lines can then be eliminated. Pictures can be used as a fill. Just be sure that the dimensions of the picture are roughly the dimension of the puzzle piece that will contain it.
There are techniques in both PowerPoint 2007 and pre-PowerPoint 2007 versions to cut a photograph into individual puzzle pieces.
Click here to go to the FAQ that explains cutting photographs into puzzle pieces.
Animations should be selected that will enhance the meaning of the message, not merely to add interest to the slide. With these frameworks, however, you can get a little creative. Pieces come come in from "out of the blue," can grow into existence, etc.

Cindy and George Anthony sat down for their first interview since their estranged daughter's dramatic acquittal of murder – and suggested that medical problems may have contributed to her erratic behavior during the disappearance of 2-year-old Caylee Anthony.
In the opening half of a widely publicized two-part interview with Dr. Phil, which aired on CBS Tuesday night, Cindy Anthony said a history of seizures and other conditions could have led to the lies Casey Anthony told at the time.
"I'm not making justification for (Casey's lies), but there's a cause for that… You just don't have a grand mal seizure," Cindy Anthony said. "I'm not making excuses for her. I want to find out what's wrong with Casey. I know that there's something wrong."
(PHOTOS: Scenes from the Casey Anthony Trial)
The toddler went missing in June 2008. Casey Anthony, 25, did not initially report her missing and eventually told police and family a fictitious babysitter had kidnapped the child. In the meantime the young mom reportedly partied at clubs, got a tattoo that read "Bella Vita" and told lies about her daughter's whereabouts.
When the child's remains were found in woods near the family home in December 2008, her story began to unravel. She was later charged with first-degree murder, but was sensationally acquitted of killing Caylee in July, and instead convicted on four charges of lying to police.
She is currently in an undisclosed location in Florida serving a year of probation on a separate check fraud conviction. Meanwhile, the mystery around what happened to her daughter remains.
The Tuesday night interview focused on Anthony family drama around the time they found out that Caylee had been missing for a month in July 2008. McGraw asked the parents why they were not more suspicious at the time.
"There's hindsight yes, but not in those 31 days," Cindy Anthony said. "I knew what I know now I would have called the Army, the Navy, anybody."
The second portion of the interview is set to air Wednesday night, while another part devoted to their daughter's trial will be shown later this month.

Moroccan spiced lamb breast with herb couscous
Jeanne Horak-Duiff
Recipe type:
Prep time:
15 mins
Cook time:
12 hours
Total time:
12 hours 15 mins
Lamb breast is an extremely cheap cut that benefits from long slow cooking, making it ideal for a sous vide machine. The Morroccan
2 cloves of garlic
1 Tbs sea salt flakes
¼ tsp sweet paprika
½ tsp ras-el-hanout
1 Tbs coriander seed
1 Tbs cumin seeds
2 Tbs thyme leaves
2 Tbs olive oil
a thick slice of butter
250g quick-cook couscous
375ml hot water or stock
A handful of fresh chives
A handful of fresh mint leaves
A handful of fresh flat-leaf parsley
salt and pepper
Fill the sous vide machine and pre-heat to 55C.
To make the spice rub, peel the garlic cloves and lightly crush them together with the salt using a pestle and mortar. Add the paprika, cumin seeds, coriander seed, ras el hanout and thyme leaves and continue to crush together. Gradually add the oil so as to end up with a thickish paste. Melt the butter in a small pan and stir into the spice paste.
Carefully remove any string or elastic tying your lamb belly roll together and flatten the meat (you may find that it is actually several pieces of flattish meat rolled together. Spread all sides generously with the spice paste.
Re-roll the meat and tie securely into a roll. Place the meat into a heavy duty plastic pouch and vacuum seal it. Place the sealed pouch into the sous vide machine, close the lid and set the timer to 12 hours.
When the meat is ready, turn off the machine and prepare the couscous. Finely chop the herbs. Place the couscous into a large bowl and add the hot water/stock. Cover with a plate and allow to stand for 10 minutes or so, then fluff up with a fork and stir in the chopped herbs. Check for seasoning and add salt and pepper as necessary.
Remove the pouch containing the meat from the sous vide machine. Cut open the bag and remove the meat, reserving the juices. If you want a crispy exterior, place the meat in a roasting tin in a very hot oven for 10 minutes, turning frequently till browned - but I did not bother with this.
If you want gravy, spoon or pour off as much of the fat as possible from the juices and heat the remainder in a small saucepan and thicken with a little cornflour mixed with cold water.
Serve the lamb sliced on the couscous, alongside slices of roasted aubergine.
NOTE: 1. I wanted my lamb medium rare but if you want yours to be medium, you need a temperature of about 60C and a cooking time of 12-15 hours; and if you want it well done you will need a temperature of 65-70C and anything from 15-20 hours. 2. If you have no sous vide machine, try slow-roasting the lamb in a closed casserole dish with 500 ml of stock at 150C for three to four hours.

It was a cool and blustery Saturday morning by Lake Michigan, but that didn't stop participants and spectators alike from coming out to take part in the 4th Annual City by the Lake Triathlon at Washington Park in Michigan City. This year there were 142 sprinters and 19 relay participants who took part in the race.
"It nearly doubled numbers from last year because we reached out to the Chicago market," Crystal Sands, Owner of Lighthouse Events and Marketing, said. "It's a very fast course. Olympic and Ironman participants use this course as training. Part of the proceeds goes toward the sports programs of Marquette and Michigan City high schools."
According to Sands, sprinters are individuals who take part in the entire race. Relay participants are individuals who form groups of two or more and each complete in a different section of the triathlon.
Due to inclement weather, the swimming portion of the triathlon was cancelled and replaced with a second running portion, thus making the race start with a half mile run, followed by a ten mile bike ride and finish with a two and a half mile run. Matt Front who hails from Highland, was a first-time triathlon participant. He and two other men were a part of a relay team.
"I'm normally a marathon runner," Frost said. "We swam in college so we thought we'd have an advantage. It was a little windy but the course was good."
Libby Harmon of Granger, IN, who counted this as her second triathlon, was in great spirits after the race ended.
"I was a little disappointed that we couldn't swim," Harmon admitted. "The run was surprisingly challenging and the bike ride was really pretty, riding by all the cottages. The community seemed to enjoy seeing everyone."
There were quite a few spectators there to watch the triathlon. There were also many individuals and businesses there donating their time and services in order to help out and enhance the whole triathlon experience.
"Great Lakes Catering donated a breakfast buffet," Sands said. "There is music, massages and Sauers here in Michigan City donated vehicles to block the wind."
After the race, participants happily dined on the breakfast buffet, chatted with family and friends or waited in line for their turn at a well-deserved massage. An awards ceremony concluded the event with medals given to the top three male and female finishers for each age division. Jeremy Kienitz, Recreation Director for the Michigan City Parks and Recreation Department, was very pleased with the outcome.
"It was very successful. No one was hurt and everyone finished," Kienitz said.
Kienitz went on to explain that this was actually the fifth triathlon held in Michigan City, but the fourth to be headed by the Michigan City Parks and Recreation Department, and the first that was done in collaboration with Lighthouse Events and Marketing.
"We started planning in November," Kienitz said. "There were about 250 people involved when all is said and done."
It was an excellent and well-executed event and everyone enjoyed themselves. The minor weather glitch didn't dampen anyone's spirits. Overall, the City by the Lake Triathlon was indeed a success.

Talks are progressing over the future capital structure of leading UK care home provider Four Seasons.
Discussions between Four Seasons owner Terra Firma and US investment manager H/2 Capital Partners are focusing on a long-term operating and financial solution for the care home group.
Four Seasons said: "Discussions with key stakeholders are progressing, with the parties actively working to reach an agreement on the long-term capital structure of the business.
"Meanwhile, the group continues to have sufficient medium-term finances for its needs. Quality and standard of resident and patient care is our highest priority and we can't envisage any scenario that would affect the quality of care for residents in our homes or patients in our specialist care units."
A spokesman for H/2 Capital Partners said: "For an extended period, H/2 Capital Partners has been seeking to develop a constructive, long-term solution that would provide stability for Four Seasons Health Care, its residents, their families and employees. Over the last six months, H/2 developed a number of proposals that, in its view, would have created a stable future for Four Seasons Health Care, in dialogue with the company's private equity sponsor, Terra Firma, and other stakeholders.
"H/2 provides senior debt capital and other financial solutions to both public companies and institutional borrowers across a variety of sectors and H/2 did not become a senior secured lender to the company with a view toward taking over its business. H/2 remains committed to working cooperatively with all stakeholders to find a long-term, sustainable solution for Four Seasons Health Care."
Four Seasons group net debt stood at £513.8m at the end of the third quarter of 2016.
Group revenue was £174.3m, up 9% year on year.
Occupancy rose to 89.6%, its highest level for three years and ahead of Knight Frank's sector estimate of 88.4%
EBITDA was £19.7m, up by 40% on the third quarter of 2015 with the group holding £51m in cash, up £10m on the previous quarter (see BREAKING NEWS: High occupancy and fee levels boost Four Seasons earnings).

NCDR, L.L.C. v. Mauze & Bagby, P.L.L.C., 2014 WL 941049, — F.3d —- (5th Cir. Mar. 11, 2014)
M&B, a Texas law firm, solicited former dental patients from plaintiff Kool Smiles' dental clinics as potential clients. Allegedly, "M&B ran television, radio, and internet advertisements, and developed a website that strongly implied, or even accused, Kool Smiles of performing unnecessary, and at times harmful, dental work on children to obtain government reimbursements." Kool Smiles sued for trademark infringement, false advertising (standing?), and "cyber-piracy" (I assume cybersquatting) under the Lanham Act. Kool Smiles also sued under state law for defamation, business disparagement, injury to business reputation, and "trade name and service mark dissolution" (dilution?). The district court denied M&B's anti-SLAPP motion, determining that M&B's speech was within the commercial speech exemption to Texas's anti-SLAPP statute, the Texas Citizen's Participation Act. The court of appeals affirmed the only issue on appeal: the applicability of the TCPA to the state claims (M&B didn't appeal the rejection of its attempt to apply the TCPA to the federal claims as well).
A structural comment: while I have no objection to M&B's interlocutory appeal, which does address an important question, merely listing plaintiff's claims makes clear that there are bigger problems with this case, which should be cut down to the disparagement/defamation claims that could, depending on the facts, potentially be sustained, and the junk should be kicked out pronto. M&B brought "several" motions to dismiss, but the district court rejected them all—according to the district court, the motions just generally attacked the plausibility/particularity of the complaints, without getting into the doctrinal reasons that the Lanham Act/trademark claims could not succeed.
The court of appeals had jurisdiction over this interlocutory appeal because, under the collateral order doctrine, the district court's order conclusively determined the disputed question; resolved an important issue separate from the merits; and was effectively unreviewable on appeal from a final judgment.
The TCPA provides an expedited means to kick out claims relating to protected speech and suspend discovery on such claims. The party bringing the claim must establish "by clear and specific evidence a prima facie case for each essential element of the claim in question" to avoid dismissal. Kool Smiles waived the argument that the TCPA doesn't apply in federal court because it conflicts with the Federal Rules of Civil Procedure, so that remains unresolved.
The district court held that M&B's conduct was within the "commercial speech" exception to the TCPA, in that M&B is primarily engaged in selling legal services to clients and that the challenged ads offered those services to potential customers. The statute says that it: "[D]oes not apply to a legal action brought against a person primarily engaged in the business of selling or leasing goods or services, if the statement or conduct arises out of the sale or lease of goods, services, or an insurance product or a commercial transaction in which the intended audience is an actual or potential buyer or customer."
There are no state supreme court cases interpreting the TCPA. Four intermediate cases have analyzed the commercial speech exemption, but none were exactly on point. One involved a defamation case arising from a series of articles in a newspaper. The court in that case borrowed the California anti-SLAPP standard for determining whether the exemption applied, including whether "the cause of action arises from a statement or conduct by that person consisting of representations of fact about that person's or a business competitor's business operations, goods, or services." The stories didn't arise out of the sale of newspapers, so the exemption didn't apply.
Here, the challenged language arose directly from the solicitation of M&B's services. "The solicitation of a service or good is inherent in the sale of the service. Otherwise, there would be a mostly arbitrary distinction created. For example, statements made while fixing a customer's roof would be exempted, but statements made while convincing a customer to hire the roofer to fix the roof would not."
Two other cases concerned businesses upset with their BBB ratings. Both held that the commercial speech exemption didn't apply, so the BBB's speech was protected, because the BBB's intended audience was not an actual or potential buyer or customer; the BBB sells its services to businesses, not to the general public, and the latter was the intended audience of the reviews at issue. Here, though, M&B's intended audience was its potential customers—potential legal clients.
M&B relied on California precedent protecting attorney ads. But there's a clause in the California statute not present in Texas's. California's statute's commercial speech exemption requires that the speech "consists of representations of fact about that person's or a business competitor's business operations, goods, or services." Soliciting clients by using statements about noncompetitors doesn't fall within that description. But Texas's commercial speech exemption contains no such limitation. Thus, M&B's ads and other client solicitation are exempted from the TCPA's protection because M&B's speech arose from the sale of services where the intended audience was an actual or potential customer.

I have a thing for black, I don't know what it is exactly but somehow I'm attracted to black. It seems easiest to layer black on black on black. I was in all black, but I switched into this white knit top last minute. I was about to head out the door, and something wasn't completely right so I threw on this chiffon skull scarf. Scarves are the best accessory, there's so many ways to wear them. I chose to just let it hang! What's your favorite way to wear a scarf?

… Now this quality of being unknown is what we have sometimes called the quality of mystery. And it is mystery which characterizes as best as we have been able to discern, the One Creator in its undistorted self. But we would also like to suggest that the mystery of which we speak is a mystery which resonates down through every distortion, every facet, and every iota of the creation. This mystery is available for participating in, and to our experience, limited though it may be, love is always the most eloquent, the most searching, and the most fulfilling way of participating in the one central mystery which is the Creator Itself.
And so, in the infinitesimally articulated experiences, down through all the densities, and in manner upon manner of creaturely existence, beyond the wildest imagination of any particular creature, there is available the possibility of taking up a direct relation to the one mystery of the creation, and making of this mystery a celebration of the creation itself as the Creator is given the opportunity to participate in a relation [that] the creature has made available to that Creator. The making available of that magical moment goes by the simple name of love.
And so when you are able to love your neighbor, when you are able to love yourself, when you are able to love the entirety of the creation with all of the shortcomings that you may perceive in it, with all of the difficult people that you may know, with all of the flaws which you may be able easily to see within your own self, then you have the greatest gift to give the Creator that the Creator ever could want. The Creator then becomes known to the Creator, just as when you love someone, that someone becomes known to you in a deeper way than they ever could be if the carrier wave of that relationship was anything else but love. …

Does the SPF of Your Sunscreen Really Matter??
- 8 Months ago
- 833
- 5.0
There are so many varieties of sunscreens available in the market that claim to protect your skin from the heat. And, the specifications of each of them are enough to confuse the buyer! These specifications range from waterproof, sweatproof, UVB, UVA, SPF 15, 20, 25, 50 etc. What do they all mean? Do they really help you?
Before getting into the details of these abbreviations, let us understand how these UV rays affect the skin. There are 2 major types of UV rays that can cause damage to your skin:
UV rays type A (UVA): These rays, though may not cause visible sunburns can penetrate deep and may damage the tissues and cause wrinkles.
UV rays type B (UVB): These types of rays are more intense and can cause tan and sunburns.
SPF (Sun protection factor) number indicates collective protection to your skin from both these types of rays. A sunscreen with SPF 30 can provide your skin 30 times the protection of no sunscreen.
So now that you know what SPF means, can an SPF of 100 give 100% protection to your skin?
No. Even a sunscreen lotion with SPF 15 can block 90% of UVB and UVA rays. So, you don't need a sunscreen with SPF 80 or 100 for adequate protection. And many skin experts say that most SPF numbers are not accurate. The results may vary individually as certain skin types tend to burn faster than others.
Skin experts recommend an application of sunscreen every two hours when outdoors especially if swimming or sweating a lot. Even if you are using an SPF 100 or 150 and it claims to be waterproof, sweatproof and provides all-day protection, it needs to be reapplied every few hours to get optimal protection especially if you are outdoors.
Remember, that sunscreens provide limited protection. Therefore it is recommended to seek shade, wear hats and a pair of sunglasses if you are out in direct sunlight for prolonged periods of time.

Take A Stand To Endure-Part 3
August 19, 2015
You and I need to be careful and you and I need to be discerning. We don't need to be anxious or depressed. Why, because we're in Christ. You're in Christ and Christ is in you.
You see, the Bible tells us difficult times are coming, and I believe this is what we are seeing today. The Bible also tells us that we are to be a light in this darkened world. Therefore, we need to keep moving forward with God. This takes faith, and as we live by faith, we must make the scriptures our standard and we must be persistent and continually on the alert. You see Satan is the author of confusion and he is like a roaring lion seeking whom he can devour. Therefore, we must keep our eyes on Jesus and we must live lives separated from this world and from worldliness. Why? Because what you focus on you will become like, and so my friends, let's keep our focus on Jesus and allow ourselves to be conformed to His image and not the image of this world.

Just another guy with a retrospective look at my experience with Mass Effect Trilogy and what it meant to me.
I don't use a numbering system really because I find that's an unnecessary tradition that lends nothing to the review itself and isn't relevant but N4G insists...
... why the 9? Absolutely massive and great trilogy but there should have been incentive other than added DLC to make this purchase the one newcomers and current fans make. This seems strictly for collectors and those missing small pieces of the series and must have those gaps filled. There simply should have been some added Trilogy-only features thrown in, is all I'm saying.
I just got this game last week. I haven't been able to play as much as I would like to, but from what I have played, I have fell in deep with this game. it's so fun I couldn't believe it i didn't play it sooner. I'll give this game a 9/10 it would have been 10/10, but it froze on me.
The trilogy and the books are amazing. Without any doubt, the greatest new franchise to come out this gen. The Mass Effect universe has so much potential to reach Star Wars level. Can't wait to see what Bioware has in store for us next gen.
All the DLC should have been included is all im saying, beings its not, this Trilogy pack is not worthy of anywhere close to a 9, Ive give it a 6 thats it.
Considering the way it was marketed by EA as the "Ultimate" Mass Effect experience, not including the DLC makes that statement less than true, but im not surprised, its EA afterall.
If im a newcomer to this series or a fan , im disappointed in EA's "business" decision to not include the DLC with this Trilogy.
I personally wouldnt purchase this, but that's my opinion, to each his own.

The first of it's kind for Mountain Equipment, the Earthrise is a sleeping bag made from 100% recycled Down and recycled inner/outer fabrics. It has exceptional environmental credentials whilst maintaining superb performance.
Season : 2020W R
Code : 003976-01476-LZ
Weight : 0KG
What is the Earthrise 400?
The Earthrise is the ideal bag for those who truly care about sustainability and ethical sourcing and don't want to sacrifice top performance and reliability (and you shouldn't have to!). We were really impressed with the construction and the care that M.E. have taken to bring you a bag that will not only perform well for years but that you can truly feel great about owning.
What is the Earthrise 400 made from?
Insulation: The Earthrise 400 contains 385g of 100% recycled down with a minimum content of 85/15 650 fill power. Taken from post-consumer waste destined for landfill in Europe, the recycled down originates mostly from used bedding. The down and feathers are removed from source and then washed, sterilised and then sorted. The majority of this recycled down goes into new bedding products, whilst only the highest quality down clusters, with a fill-power of 650 or higher, are used in Mountain Equipment's Earthrise products.
All that recycled down has exceptional environmental credentials while maintaining superb performance. It is all sourced from a European facility powered by solar power, is washed in a plant with extremely efficient water recycling before being graded for quality. Mountain Equipment's use of only the finest grade of recycled down, guarantees not only an ethical purchase but a high performance one. This process saves a valuable material from landfill and by eliminating the farming process that produces virgin down, it vastly reduces the carbon footprint of down production.
Fabrics: All Earthrise sleeping bags are constructed using 100% recycled outer and inner fabrics. These are environmentally-sound fabrics with excellent performance characteristics. Earthrise 20D is used on the outer and is incredibly soft to the touch, wind resistant, comfortable and totally down-proof. It also only weighs 45g/m². The inner fabric is also 100% recycled and is soft, breathable, down-proof, durable and weighs in at only 59 g/m². Combined, these fabrics offer exceptional environmental benefits without sacrificing performance or the look and feel of these high-performance sleeping bags.
What is the construction used in the Earthrise series?
Mountain Equipment's bags are very unique in a number of ways. One is the way they optimise their heat efficiency by using slanted box-wall baffles throughout the entire main body of the bag meaningful weight is removed from the bag's structure.
Mid-level side-seams lift potential cold spots away from the floor, irrespective of sleeping position, and allows versatile distribution and optimisation of the filling throughout the bag. Mountain Equipment their vast experience and knowledge to place a higher density of down in the underside, hood and foot, areas prone to compression. Whilst the upper of the bag has larger roomier baffles creating more "loft" space to reduce radiant heat loss. The specially designed foot section is anatomically shaped for a more natural sleeping position and uses four baffles to make sure your feet are cocooned in as much down as possible. A high percentage of your body heat is lost through your head so Mountain Equipment has developed a hood section which uses 5 baffles to create a truly anatomical shape to surround your head with luxurious warmth.
What are the features?
To further optimise insulation M.E have developed the Gemini System that has two overlapping anti-snag draft tubes, a full-length zip and a fully integrated neck collar with Lode Lock closure. This clever, low profile, closure combines all the advantages of a magnetic fastener with those of a mechanical lock, so no more traditional press-studs. The one-handed quick release closure uses two captivated magnets to pull the locking mechanism together to ensure that the insulated neck baffle cannot be accidentally opened, keeping all that lovely warmth where it should be; inside the sleeping bag.
Earthrise bags are also supplied with a waterproof roll-top stuff sack and a lofting storage cube to store your bag when it's not out on adventures. Storing a down bag fully lofted (and not in its compression sack) helps to stop the sleeping bag from losing its loft (ability to insulate) over time.
How does the Earthrise fit?
The Earthrise fits into Mountain Equipment's 'Alpine Fit' block which is tapered in the upper body and the legs to maximise thermal performance and minimise weight.
How warm a sleeping bag do you really need? We've tried to help you by grouping our sleeping bags by their recognised comfort ratings. These are the ratings supplied by the brands that indicate the temperature at which you will remain comfortable whilst sleeping on a good insulated sleep mat. After all, comfortable is what you want to be when it's cold and wet outside and you're all tucked up in your nice warm sleeping bag.
We always recommend that you choose your bag according to the coldest conditions you will experience; you can always unzip a bag if it is too warm, but trying to sleep when you're too cold is just miserable. Bear in mind that that we are all individuals and we all feel the cold differently, and that our own resistance will fluctuate depending a whole load of factors including how much we have eaten, whether we have consumed alcohol, whether we need a wee or what kind of mood we are in!
Sleeping bags do not generate heat they only trap the heat we produce so it is vital that you get into your bag when you are giving off warmth, don't go to bed when you are cold, have a hot meal or a hot drink or do some brisk exercise to get you nicely warmed up.
Traditionally sleeping bag manufacturers provided their own temperature ratings based on their experience, the products intended end use and the perceived environment. But each brand tested their bags in different ways and it was hard to find a fair comparison between models. So, in 2005 a European standard for sleeping bag temperature ratings, EN 13537, was introduced to give consumers a comparable guide to sleeping bag performance across a range of brands and models. The ratings have four different temperature ratings to give you an indication of the bags performance.
Upper limit: This is the highest temperature at which an average male should experience a comfortable night's sleep.
Comfort: This is the temperature at which an average female should experience a comfortable night's sleep. On average women sleep colder than men so this rating is some degrees above the 'comfort lower limit' for a man.
Comfort lower limit: This is the lowest temperature at which an average male should experience a comfortable night's sleep whilst lying in a curled-up body position. This used to be known as the comfort rating.
Extreme: This is a survival rating where the user is likely to suffer health damage such as Hypothermia. It should be treated with the utmost caution and not be relied on for general use.
However, the EN 13537 European Standard does not apply to down filled sleeping bags with a fill weight of more than 800g; for those bags you will have to rely on the manufacturer's experience and technical expertise, which is often more accurate!
Most reputable brands still use their own rating system alongside EN 13537, for instance the M.E "Good Night's Sleep" and Rab's "Sleep Limit". These ratings are often the most accurate guide to the overall performance of a bag being used by an average outdoor enthusiast. They are based on years of expedition heritage, field trials, technological experience, and constant feedback.
But please bear in mind that all ratings are only a guide and, as mentioned earlier, there are a huge range of factors that can affect your comfort, if you are just not sure it is always wise to go for a warmer model.
The biggest difference you can make to your overall comfort is to use an efficiently insulated sleeping mat. Once you get inside your sleeping bag you instantly compress all the filling beneath you, greatly reducing its efficiency. The use of a quality sleep mat will ensure you are properly insulated from the cold ground and you will of course be a lot more comfortable. Your sleeping bag is only as good as the mat that's beneath it; we recommend EXPED, ThermaRest or Multimat sleeping mats for comfort and insulation.

Hello. I am experiencing a problem with my Catalina vanilla installation.
My Dell 7567's screen is constantly blinking. This started in the installer and persisted after successful installation. Apart from the mentioned, the system is working perfectly fine.
I am able to disable the backlight completely by pressing F11/brightness down button. I am barely able to see the on-screen text using a desk lamp afterwards.
I have tried installing AppleBacklightFixup.kext, Lilu.kext and WhateverGreen.kext and setting my SMBIOS to iMac18,1 but none of those proposed solutions have helped me so far.
To illustrate the problem, I have recorded a video (link) of my laptop booting into the installer and then shutting down. I have also included my CLOVER folder.
I would appreciate any help or advice.
Best regards, Luka

In this thread, I have fully documented the installation of macOS Catalina on my HP EliteDesk 800 G4 Mini. It is a PERFECT HackMini8,1 and is running very well for me without any issues. I hope this documentation helps you to install macOS on your hack. Please leave feedback if you think there is anything I can improve and let me know if you have any questions.
This is my first "modern" hack supporting UEFI and my first hack using Clover "on-the-fly" patches. My previous hacks
Laptop: Thinkpad T61 / Nvidia NVS 140m Laptop: Dell Latitude E6410 / Nvidia G3100m Desktop: Gigabyte G31 / GeForce 9600 Desktop: Biostar TH55HD / Sapphire Pulse RX580 (Google "Catalina Biostar TH55HD" and look for user name deeveedee)
are all perfectly running Catalina and I patched them all "manually" - all DSDT patches applied with MaciSL with virtually no Clover on-the-fly patching and all booted Legacy Clover. This UEFI hack was MUCH easier and took about 20 hours vs. a combined hundreds of hours for the old hacks. I wanted a hack that was a little more future proof and I think this is it. I hope you enjoy this as much as I am enjoying it. It is a perfect MacMini8,1.
